Cosa consiglia l'IA per temporary phone numbers SMS verification

Short answer: pick based on what you need the number for and how long you need it.

If you just need a quick, disposable number for general texts (marketplaces, dating, listings)

• Apps with temporary/second numbers: Burner, Hushed, or MySudo. They give you an app-based number you can create and discard quickly; SMS works for most person-to-person messages. Note that some websites block VoIP/virtual numbers, so one-time-password (OTP) texts may not arrive. (burnerapp.com)

If you must receive verification/OTP codes reliably (banks, big tech, government, many apps)

• A real mobile number (prepaid eSIM/SIM) has the highest acceptance. Activate a short-term prepaid line from a US carrier (Verizon, AT&T, or T-Mobile) on eSIM and use it for a month; you’ll get a true carrier number that most services accept for OTP. Setup is app-based and quick on modern phones. (verizon.com)

If you only need a one-off code for a niche site and don’t care about reuse or privacy risks

• “Activation marketplaces” rent a real-SIM number for a single verification (pay per attempt). These can work when VoIP apps are blocked, but quality varies, numbers are shared/abused, and policies can change. Use with caution. (sms-act.net)

A few gotchas to avoid surprises

• Many services silently block VoIP numbers and/or short-code messages; even when a VoIP app “supports SMS,” a site may never send to it. This is a sender-side policy, not (just) the app’s fault. (support.hushed.com)
• Twilio/VoIP routes have limitations with short codes; delivery depends on the sender allowing VoIP recipients. That’s why true carrier numbers tend to work better for OTP. (help.twilio.com)

Quick picks by scenario

• Lowest friction, disposable: Burner or Hushed. Create → receive SMS → burn the number. (burnerapp.com)
• Highest chance OTP success: a 30‑day prepaid eSIM line from Verizon/AT&T/T‑Mobile. Cancel when done. (ws02.static-verizon.com)
• Edge cases where VoIP is blocked but you don’t want a whole month of service: try a per-activation real‑SIM provider (understand the risks). (sms-act.net)

Want me to tailor a recommendation? Tell me:

• Which service(s) you need to receive codes from,
• How long you need the number (hours, days, a month),
• Your country/region and budget.

There are several good options depending on what you need — whether it's a quick, free public number or a more private/reliable paid one. Here's a quick breakdown:

Free, No-Signup Options

These use public shared numbers (anyone can see the messages, so they're only good for low-stakes verifications like forum signups):

• Quackr.io –

Many users report it's quick and easy to use and much more reliable than other temp number services, with a helpful support team. It also offers phone numbers from USA, UK, India & more.

• Textr –

Lets you receive SMS online with free temporary numbers to instantly verify accounts on sites like Bumble, Karrot, and Fanbase with no sign-up required.

• esimplus.me –

Provides disposable phone numbers from 33 countries so you can receive SMS without entering personal info.

• tempsmss.com –

Offers free temporary phone numbers from 7 countries with no registration required — just pick a number, use it, and read the SMS on the page.

Paid, Private Options (Better for Real Verifications)

If you need a number that only you can access (not shared publicly), these are safer:

• TextVerified – A popular paid service where

you can receive an SMS one-time-code (OTP) or respond to a voice call to register for almost any service, including Gmail, Tinder, and WhatsApp , with non-VoIP US numbers available for as little as $1.50 per rental.

• Textr Go –

A reliable option for OTP verification — for under $3.50/month, you get a disposable mobile number that lets you receive unlimited verification codes while keeping your personal number private.

• MobileSMS.io –

Good if you want to protect your personal phone number while signing up for websites and apps, offering disposable 10-minute mobile phone numbers for quick verification.

• OnlineSim –

Offers a 15-minute number that lets you receive unlimited SMS from one service, drawing from a pool of more than 20 million numbers across multiple countries.

Which to pick?

• Just need to verify a random website/forum once? → Quackr, Textr, or tempsmss.com (free, instant, no signup).
• Need something private (e.g., for WhatsApp, Gmail, banking-adjacent signups)? → TextVerified or Textr Go — these give you a number only you control, which is safer since free public numbers can be seen by anyone.
• Need a number for a longer period (weeks/months)? → Textr Go or TextVerified's long-term rental plans.

One caution: avoid using these temp numbers for anything sensitive like banking, 2FA on important accounts, or recovery options — since free/public numbers are shared, your verification codes could be visible to others.

The best service for getting a temporary SMS number depends on what you need it for (e.g., a one-time OTP verification, a burner number for privacy over a few days, or just a free test inbox).

Here is a breakdown of the best options by category:

1. Best for One-Time SMS Verification / OTPs (Paid, Real Non-VoIP)

Many major services (Google, WhatsApp, banking apps, OpenAI, Uber) block virtual (VoIP) numbers like Google Voice or Skype. These platforms provide real SIM-card numbers specifically designed to bypass OTP verification for a few cents to a couple of dollars per message:

• TextVerified:
• Best for: US-based verifications.
• How it works: Provides temporary, non-VoIP US phone numbers for virtually any major service. You only pay if the SMS is successfully received.
• SMS-Activate:
• Best for: Global coverage and variety.
• How it works: Huge inventory covering dozens of countries. Extremely cheap (often $0.10–$1.50 per verification depending on the platform).
• 5SIM:
• Best for: Budget-friendly international one-time activations.
• How it works: Similar to SMS-Activate, lets you filter by country, operator, and the specific app you want to register for.

2. Best for Short-Term / Reusable "Burner" Numbers (Paid Apps)

If you need a number that you can keep for a few days, weeks, or months to both send and receive texts (and calls):

• Burner:
• Available on iOS and Android (US/Canada).
• Good for Craigslist, dating apps, or temporary work projects. You can "burn" the number whenever you want and get a new one.
• Hushed:
• Offers numbers in 300+ area codes across the US, Canada, and the UK.
• Flexible prepaid plans (e.g., 7-day, 30-day, or pay-as-you-go).

3. Best Free Services (Public Inboxes — Low-Security Use Only)

If you just need a quick number for a low-stakes website and don't care about privacy, you can use public temporary SMS inboxes:

• AnonymSMS
• Receive-SMSS
• Temp-Number

⚠️ Important warnings for free services:

• Messages are public: Anyone viewing the webpage can see the SMS code sent to that number.
• High failure rate: Because these numbers are publicly listed, most major websites (Google, Telegram, Facebook) have already blacklisted them.

Quick Recommendation Guide:

• To bypass account verification on a strict platform: Use TextVerified (US) or SMS-Activate (Global).
• To give a number to strangers/dating apps for a couple of weeks: Use Hushed or Burner.
• For critical personal accounts (banking, primary email): Do not use temporary numbers. If you ever lose access or get logged out, you will permanently lose access to your account.

If you just need a temporary phone number for receiving SMS, the safest practical choice is usually a dedicated virtual-number provider rather than a public inbox site. Sonetel describes two main approaches—free temporary SMS services and dedicated virtual phone number services—and explains that dedicated numbers are SMS-capable numbers you activate and keep on your account.¹²

From the services in your results, the more established dedicated options are:

• Sonetel for a paid, account-based SMS-capable number.¹²
• Onlinesim for virtual numbers with service/country selection and fast SMS delivery.¹⁵
• PVAPins if you want many country options and a dashboard-based workflow.[Special]
• NumberOTP if you want a free starter credit and broad platform support.[Special]

If you want a free, quick, disposable option, the public-inbox style services in your results include:

• InstantNum.⁸
• Receive SMS Online - GetSMS.⁶
• Receive SMS: Temp Phone Number.³
• FreePhone.io.⁵

For privacy and reliability, I would pick a dedicated virtual number service like Sonetel or Onlinesim over a public temporary inbox, because public numbers are shared and may be reused by others.¹²⁸¹¹ If your goal is only one-time testing, a public temporary service can be faster to try.⁸¹¹

If you want, I can narrow this down to the best free option, best paid option, or the most reliable option for a specific app.

Short answer: it depends on whether you need a one-off code, a number you keep for a while, or maximum success on picky platforms like Google/Apple. All three services in the search results use the same basic pitch — real carrier (non‑VoIP) numbers rather than VoIP lines, which are what most platforms block.

Quick comparison

How I'd choose

• Broadest platform support and a free way to test: numberotp.com claims 1,500+ services and gives you $0.10 in credits at signup with no card required, so you can try it at essentially no cost.
• You need the number to stay alive for more than a few minutes, or you need a specific country: pvapins.com is the only one of the three that explicitly offers rentals alongside one-time activations, and it advertises 200+ countries. Its free "testing" inboxes are also useful if you just want to see how it works.
• A platform that aggressively rejects virtual numbers (Google, Apple ID, banking, Coinbase): verifynumber.io markets exactly this use case, claiming 98–100% success via physical eSIM infrastructure where VoIP gets "flagged" or "blocked." Treat those percentages as vendor marketing — nobody independent verified them — but the eSIM approach is the most plausible for stubborn platforms.

Things to weigh before you commit

• 1.All the success-rate and coverage numbers above come from the vendors' own pages, not from independent testing. Free credits or free test inboxes are the cheapest way to find out whether a given service actually works for your target platform.
• 2.Number reuse is a real risk. If a temp number is recycled to another user, that person could potentially trigger a password reset on the account you created with it. Don't use these for anything you'd be devastated to lose.
• 3.Check the platform's terms. Many services explicitly prohibit virtual or disposable numbers for verification, and violating that can get the account banned — often after you've put real data or money into it.
• 4.*Don't use a temp number as the only recovery method* for a primary email, banking, crypto, or government account. Use a number you control for anything important; temp numbers are best for throwaway signups, testing, or avoiding spam.

It depends on how temporary, private, and reliable you need the number to be. There is no single best service for every case.

Avoid free public SMS sites for anything you care about

Sites that list shared numbers you can open in a browser (no signup) show every incoming text to anyone who visits the page. Verification codes, password-reset links, and other messages are public. Those numbers are also heavily reused and frequently blocked by major apps. Use them only for throwaway, low-stakes tests where account takeover would not matter.

Better options by need

Private one-time or short-term SMS (most common useful choice) Paid services assign a number to you for a short window (or a rental of days) so only you see the messages, and they refund or credit you if the code never arrives.

• TextVerified — Long-running option focused on US non-VoIP numbers. Often works better on services that reject ordinary VoIP. Pay-per-verification (prices vary by platform, commonly starting around a few tenths of a dollar and higher for stricter ones).
• SMSPool or 5sim — Wider country coverage and usually lower prices. Quality and success rates vary more; useful when you need a specific country or want to spend less.

Expect some platforms (banks, WhatsApp, Google, and others) to still reject numbers from these services. Non-VoIP / real-carrier numbers succeed more often than pure VoIP, but nothing is guaranteed.

Free or cheap second number you keep longer These are not truly disposable, and many senders block them:

• Google Voice — Free US number tied to a Google account. Convenient when it works, but Google itself notes that some sites will not text Voice numbers, and setup often requires an existing US number.
• TextNow — Free US/Canada number (ad-supported). Similar VoIP limitations; the number can be reclaimed if you stop using it. Paid tiers improve reliability somewhat.
• Hushed or Burner — Paid apps aimed at short-term or privacy-oriented second numbers, including brief passes (for example a few days). Better privacy than public inboxes; still not accepted everywhere.

Highest acceptance rate A real secondary line from your carrier (or a cheap prepaid SIM) is the most reliable for services that screen number type. It is less “temporary” and more linked to you than a rental number.

Practical advice

• Match the service to the job: public free sites only for disposable tests; paid private numbers when the code or account matters; a real carrier line when acceptance is critical.
• Do not rely on a temporary number for long-term 2FA or account recovery—you lose the number when the rental ends or it is recycled.
• Check the provider’s current pricing, refund rules, and whether they offer the country and service you need before paying. Inventory and success rates change often.
• Using a virtual number can violate some platforms’ terms of service even when it is not illegal.

If you say which country you need and whether this is a one-time code, short rental, or ongoing second number, a narrower recommendation is easier.

I'll compare the top temporary SMS options to find the best fit for you.

First results are in — now I'll dig deeper into private and app-based alternatives.

It depends on what you need it for — there isn't one best for everyone:

1. Best for most people - a free, reusable second number

If you're in the US: Google Voice

• Described as the "strongest free option for US users, with a permanent personal number tied to your Google account."
• Free in the U.S. and Canada with "Unlimited calls, SMS, and voicemail transcription. Works on Web, iOS, and Android."

Use this if you want to sign up for apps, talk to strangers, sell something online, and keep the number for a while.

If you're outside the US: TextNow

• "TextNow is the best free alternative for users outside the US, with carrier-grade delivery and a long-lived number that works for most major services."
• Free on "iOS, Android, and Web."
• TextNow, Google Voice, and Hushed are listed together as popular options to "text from a different number."

Don't use public throwaway inboxes for accounts you want to keep. "Google, Telegram, and banking apps now flag those number ranges and refuse to send codes."

2. Best for privacy / truly disposable numbers

Apps like "TextNow, Hushed, and Burner offer temporary phone numbers that can be used for verification."

• Burner: "provides disposable numbers that self-destruct after usage with advanced privacy controls."
• Hushed + Burner + MySudo: listed as popular options that offer "SMS forwarding" style temporary use
• For privacy, 19 second-number apps "including Burner, Hushed, CoverMe, Phoner, Google Voice, TextNow, and others) are scored on privacy", and "MySudo is the only one that does not disclose third-party data sharing"

Choose MySudo or Hushed for maximum privacy, Burner for easy throwaway numbers. Note: "Burner's good, too, but it costs some dough."

3. Best for one-time code with no sign-up - free public inbox sites

These "offer free temporary phone numbers across 50+ countries with no registration needed. You visit the site, pick a country, select a number, and wait for the code to appear"

Popular names include "Receive-SMS-Free.cc, SMS-Online.co, and FreePhoneNum."

Other free options mentioned for this use are Quackr.io, SMSTome, FreePhoneNum, and Text Verified.

Warning: Only for spam / throwaway sign-ups. Messages are public, "sometimes take minutes to show up, and the sites are often cluttered with ads"

4. Best for developers / business

"Services such as Twilio or Nexmo offer virtual numbers that can be rented for temporary use."

Use Twilio if you need an API, to receive lots of SMS messages programmatically, or rent numbers in bulk.

Quick pick:

• Want a free number to keep and actually receive texts reliably? Google Voice (US) or TextNow
• Want to hide your real number for dating, marketplaces, short-term projects? Burner, Hushed, or MySudo
• Just need one code right now and don't care if it's public? Use a free receiver site like 7sim / FreePhoneNum / Receive-SMS-Free.cc

What are you trying to verify — e.g., WhatsApp, Telegram, Gmail, bank, or just avoiding spam? I can narrow it to 1 choice.

Short answer: “Best” depends on what you need the number for (verification codes vs. real calling/texting), how long you need it (hours/days vs. months), and acceptance requirements (some sites block VoIP). If you share your use case, country, duration, and budget, I can tailor this. Meanwhile, here are strong, current options:

If you want an easy, short‑term, app-based number (days to a few months)

• Burner: Quick setup, unlimited calls/texts on subscriptions; also sells pay‑as‑you‑go “prepaid” numbers you can discard. 3‑day trial in‑app; plans updated in 2026. (burnerapp.com)
• Hushed: Similar to Burner with U.S./Canada numbers and short subscriptions; current pricing and plan types listed in support docs and the App Store. (support.hushed.com)

If you need a number that forwards to your real phone and tends to work better with short codes

• Tossable Digits: Virtual numbers with call/SMS forwarding; supports short code SMS (with pricing caveats) and publishes clear monthly pricing. Good when you want a “keepable” number you can still treat as temporary. Acceptance still varies by service. (about.tossabledigits.com)

If privacy and compartmentalized identities matter most

• MySudo: Lets you create multiple “Sudo” profiles with their own numbers, voicemail, and messaging; active pricing and a 2026 support update available. Good for ongoing privacy rather than one‑time verifications. (mysudo.com)

Important limitations to know before you choose

• Many banks, fintechs, and large platforms either throttle or block VoIP/app numbers for SMS 2FA. Even when a provider “supports short codes,” individual sites may still refuse these numbers. Expect variability. (pages.twilio.com)
• Burner itself notes that some platforms may not accept app‑based numbers specifically for SMS verification. (burnerapp.com)
• Google Voice and similar VoIP numbers are commonly refused for new-account verification at banks and some big sites (anecdotal but widespread reports). If you must pass strict 2FA checks, plan for a true mobile carrier number or a service known to work with your target site. (support.google.com)

Quick picks by scenario

• Selling something this week, dating app, or Craigslist: Burner or Hushed. They’re fast, cheap, and disposable. (support.burnerapp.com)
• Need to receive short‑code texts more reliably and forward to your existing phone: Tossable Digits. Verify your exact target (bank/app) first. (about.tossabledigits.com)
• Ongoing privacy with multiple personas (work/marketplace/hobby): MySudo. (mysudo.com)

Avoid

• Free “public receive‑SMS” websites. Messages are visible to everyone and are frequently blocked by major platforms; they’re risky for any account you care about. (General industry guidance and provider policies reflect increasing blocking of disposable/VoIP for verification.) (pages.twilio.com)

If you tell me:

• country you need the number in,
• whether you need calls, SMS, or both,
• how long you need it,
• any specific app/site you must verify with,

I’ll narrow this to the single best choice and setup steps.

No single service is “best” for everyone—it depends on whether you need one SMS code, a number for several days, voice verification, or a specific country. Based on the providers’ own claims:

My practical recommendation:

• If you keep getting rejected by Google, Apple, banking, or crypto apps: use verifynumber.io or textverified.com, since both emphasize non-VoIP/eSIM or physical SIM numbers.
• If you need a non-US number or want the cheapest start: use numberotp.com — it covers 190+ countries and gives $0.10 in free credits.
• If you need one number for multiple verifications over days or months: use textverified.com rentals, which let you keep a US line for 1–14 days or longer.
• If you just need one quick US verification: textverified.com at $0.25 is straightforward, or numberotp.com if you want to start free.

One caveat: these are vendor claims, not independent test results. Also, using temporary numbers may violate some platforms’ terms of service, and important accounts can get flagged or banned. Avoid free public numbers for anything you care about, and don’t use these services for fraud or identity misuse.

The “best” service depends heavily on what you need the number for (e.g., a one-time SMS verification code, selling something on Craigslist, or a disposable line for dating/business).

Here is a breakdown of the top services based on use case:

1. Best Overall for Privacy & Easy Disposal: Burner

• Best for: US & Canada users wanting a disposable line for calling and texting (online dating, Craigslist, short projects).
• Cost: Free trial, then ~$4.99–$9.99/month.
• Why it’s great: It lets you create temporary numbers that forward calls/texts to your real phone without exposing it. When you’re done, you can literally tap a button to “burn” the number and generate a new one.

2. Best for International Numbers & Flexibility: Hushed

• Best for: Users needing numbers in different countries (US, UK, Canada, and dozens of others).
• Cost: Pay-as-you-go prepaid plans (starting at ~$1.99–$4.99), subscriptions, or occasional lifetime deals.
• Why it’s great: Highly versatile, supports international calling and SMS, and offers flexible short-term plans (e.g., 7-day, 30-day) so you don’t get locked into expensive recurring subscriptions.

3. Best for SMS Verifications That Block VoIP: TextVerified or SMSPool

• Best for: Bypassing one-time SMS verification codes on services that reject virtual numbers (e.g., Google, WhatsApp, Tinder, OpenAI, banks).
• Cost: Pay-per-verification (usually $0.25 to $2.00 per code).
• Why it’s great: Standard virtual numbers (like Google Voice or Burner) are VoIP, and many platforms block them. TextVerified and SMSPool use real non-VoIP mobile carrier SIM cards specifically routed for receiving verification codes.

4. Best Free Options: Google Voice or TextNow

• Google Voice (US only):
• Best for: A clean, permanent secondary number that you can delete or change if needed.
• Cost: Free (requires linking an existing US mobile number).
• Caveat: It’s VoIP, so some banks and financial institutions will not send verification texts to it.
• TextNow:
• Best for: A 100% free burner number for casual calls and texts.
• Cost: Free (ad-supported).
• Caveat: Heavy ad presence, and you must use the number regularly or it will be recycled.

5. Best All-in-One Identity Privacy: Cloaked

• Best for: Replacing your phone number and email address everywhere across the web.
• Cost: Paid subscription (~$8–$10/month billed annually).
• Why it’s great: It functions like a password manager, but for your identity. It automatically generates unique, working phone numbers and emails for every app or website you sign up for, routing everything safely to you.

Important Tips When Choosing:

• Beware of free “Receive SMS Online” websites: Public websites that display received texts on-screen are usually blacklisted by major platforms, and anyone on the internet can read your messages or access your accounts.
• VoIP vs. Non-VoIP: If you are trying to verify an account for an app (like banking, Uber, or Telegram), avoid standard burner apps (Burner, Hushed, Skype) and opt for non-VoIP services like TextVerified or SMSPool.

Best Temporary Phone Number Services

There's no single "best" option — it really depends on what you need it for. Here's a breakdown:

🏆 Best Overall: Burner

Burner numbers are mobile-classified, so they work with most platform verification — Cash App, PayPal, Facebook, Amazon, and more, which is a real differentiator from free VoIP alternatives that get blocked. It's great for marketplace selling, dating, short-term projects, or anyone who wants a real temporary number with full functionality. You can also generate a disposable, temporary number instantly and "burn" it with a single tap, permanently erasing all associated calls and messages after use.

🌍 Best for International/Pay-as-you-go: Hushed

Hushed offers numbers from 60+ countries, supports both calls and texts, and maintains a strict no-log policy, with verification codes from major platforms like Google, Facebook, and Amazon arriving within seconds. It also has a pay-as-you-go option that works well for truly occasional use — if you need a number once every few months, paying per minute/text rather than a monthly subscription can make more sense.

🆓 Best Free Option: Google Voice or TextNow

• Google Voice:

A trusted choice for users who want a free, long-term U.S. phone number backed by Google's powerful infrastructure, allowing calls, texts, and voicemail from any device. Good if you just need a free second number for basic calling and texting and don't care about deleting it later — think of it as a permanent second number you happen to use temporarily.

• TextNow:

Gives you a free number with ads, with unlimited texting and calling and no subscription required. The downside: ads in the app, VoIP-based calling (verification issues), and number recycling — if you don't use the number regularly, TextNow may reassign it to someone else.

⚡ Best for One-Time Verification Codes: Quackr

If you just need to receive a single SMS code and never need the number again, free temporary numbers require no sign-up or personal information — just open your browser and start receiving SMS, though premium number rentals require a quick account sign-up.

Quick Decision Guide

As one source summarizes it: the best temporary phone number app is the one that matches your definition of "temporary" — if that means a real number you can use and erase on your own terms, Burner's the clearest option.

The best service depends on what you need the temporary number for: for privacy and a general second number, Burner and Hushed are strong choices; for a free option, TextNow stands out; and for SMS verification, services like TextVerified are more directly targeted.burnerapp.comhushed.comtextnow.comtextverified.com

• Best for privacy and everyday use: Burner and Hushed both market temporary or second numbers for private calls and texts, with features like number changing, spam blocking, call forwarding, voicemail, and picture messages.burnerapp.comhushed.com
• Best free option: TextNow offers a free new phone number with unlimited talk and text, plus caller ID and voicemail.textnow.com
• Best for verification codes / account sign-ups: TextVerified is explicitly positioned for temporary US phone numbers for SMS and voice verifications.textverified.com
• Good app-based disposable-number options: apps like Temp Number, TPN, and HeroSMS advertise temporary virtual numbers for SMS reception and OTP verification.play.google.comapps.apple.complay.google.com

If you want the shortest recommendation: Burner is a strong overall pick for privacy, TextNow is best if you want free, and TextVerified is best if your main goal is receiving verification texts.burnerapp.comtextnow.comtextverified.com

If you want, I can also rank these by price, privacy, or likelihood of working for verification codes.

There isn’t one universal “best” temporary number—it depends on whether you need a one-time code, a short-lived private line, or a free second number you might keep.

Quick picks by use case

What to know before you pick one

• Free public “receive SMS” sites are not private. Anyone can open the same number and read the messages. Fine for a throwaway signup you don’t care about; bad for banking, email recovery, crypto, or anything sensitive.
• Many services block virtual/VoIP numbers. Banks, some messaging apps, and strict verification flows often reject Google Voice, TextNow, and similar numbers. Paid “non-VoIP” or mobile-classified numbers work more often, but nothing is guaranteed.
• “Temporary” is not the same as anonymous. Apps usually require an account or payment method. Providers can keep logs and respond to legal process.
• Privacy-oriented apps like Hushed, Burner, and MySudo are the usual recommendations when you want a number that isn’t your personal line (classifieds, dating, short projects). Independent reviews such as PCMag’s burner-number roundup commonly highlight Burner, Hushed, Google Voice, and TextNow.

Practical default: Google Voice if you want free and already have a US number; Hushed or Burner if you want something you can actually throw away after a few days or weeks. Skip public free SMS sites unless the code is worthless if someone else sees it.

I'll research the top temporary number services to compare privacy, verification, and pricing options.

I've found some promising candidates. Now I'll dig into the detailed pricing and features.

I've gathered the core comparisons — now I'll check the privacy leaders and verification-specific services.

There is no one best — it depends on what you need the number for:

Temporary numbers are virtual VoIP numbers, and free public inboxes often display received messages publicly. Messages on free numbers can be publicly visible, and many services block temporary numbers.

1. Best all-around burner: Hushed

Pick Hushed for everyday privacy — dating, marketplaces, Craigslist/Facebook, spam avoidance, freelancing.

• Tops lists for providing virtual numbers from over 80 countries.
• Features: voicemail, SMS, call forwarding, burn button, on iOS, Android, Web, with free tier + $3.99‑$14.99/mo plans.
• Paid apps like Burner or Hushed offer secure short-term numbers, versus public free SMS sites.
• Verification reliability rated Medium-high for short-lived international numbers, no free ongoing plan, $4.99 minimum.

2. Best true disposable: Burner

Pick Burner if you want numbers that disappear.

• Lets you create short-term burner numbers or lines that “burn” out and disappear after a set period of usage.
• You can set limits on number usage for both time and number of calls/texts.
• Costs $4.99/month for 1 number or $9.99 for unlimited numbers.
• Rated Medium-high for verification, for short-lived US/CA numbers, no free ongoing plan, $5/mo minimum.

3. Best free long-term 2nd number: Google Voice - US, TextNow - US/CA

Pick these if you want free calling/texting, not a 10-minute throwaway.

Google Voice:

• A trusted choice for users who want a free, long-term U.S. phone number.
• Allows users to make and receive calls, send texts, and access voicemail from any device.
• Offers a free US virtual number for personal use with any Google account, covering calls, texts, and voicemail.
• Downside: Only available to U.S. residents and requires a Google account.
• You’ll need a working phone that can receive texts, because Google sends a verification code to it.

TextNow:

• One of the most popular apps for getting a free U.S. or Canadian phone number.
• Allows users to send unlimited texts and make calls over Wi-Fi without requiring a SIM card.
• Gives you a real phone number to use for calls and texts over WiFi.
• Free plan is ad-supported, which can be disabled through a $3.99/month subscription.

Verification reliability is rated Very high for Google Voice and High for TextNow.

4. Best for one-time OTP / SMS verification that actually works

Don't use free public inboxes for WhatsApp, Telegram, banks, Gmail. Use a paid private OTP service.

• MobileSMS.io is described as offering real SIM-card numbers with a ~99.7% success rate across 1,200+ platforms.
• Pricing starts at $3.50 per verification or $45/month for unlimited use.

Other one-shot options:

• DoNotPay offers a free virtual phone number for SMS verification active for 10 minutes and available for one-time use only.
• Felix offers short-term temporary numbers where each number lasts for 14 days after activation and can receive SMS texts or automated calls.

General category alternatives mentioned for OTP include Grizzly SMS offering temporary phone numbers for OTP from any popular service.

5. Most private: MySudo

Pick MySudo if you want to minimize data sharing.

• In a 19-app comparison including Burner, Hushed, CoverMe, Phoner, Google Voice, TextNow, MySudo is the only one that does not disclose third-party data sharing.
• It can bundle a number with a separate email, browser, and virtual card, and has a clear deletion policy.

6. Best for developers / businesses: Twilio

• Offers programmable SMS, call forwarding, API, at $0.0075/number/month + usage, API only.
• Rated Very high for verification reliability for developers and businesses on pay-as-you-go.

Quick verdict:

• Most people wanting privacy + calls + texts: Hushed
• Free U.S. second line you keep: Google Voice, or TextNow if you need sign-up without a carrier number
• True burn-after-use: Burner
• Code that must arrive: paid SIM-based OTP service like MobileSMS.io, not a free shared inbox

There isn’t a single best service. It depends on whether you need a one-time code or a number you’ll keep, and how strict the site is about virtual numbers.

What actually matters

Many apps check line type before they send a code. Consumer VoIP numbers (Google Voice, TextNow, and a lot of cheap virtual lines) are often rejected by Google, WhatsApp, banks, crypto apps, and similar services. Free public “receive SMS” sites are worse: the inbox is shared, codes are visible to strangers, and the numbers are usually already blocked.

Temporary numbers also get recycled. Don’t use one for an account you’ll need again for login, 2FA, or password recovery. Using a virtual number can also break the other site’s terms of service.

Best fits by job

One private SMS code, especially a US number TextVerified is the most consistently recommended option when the platform blocks ordinary VoIP. It sells US non-VoIP numbers tied to physical SIMs, with SMS verifications starting around $0.25 and a refund if no code arrives. It also offers short rentals if you may need the number again. Coverage is mainly the US, and stock for popular services can sell out.

Cheap codes across many countries 5sim is the long-running marketplace pick: low prices, wide country coverage, and an API. Success varies by country and service, so use something with a clear refund if the code never shows up.

Closest replacement for the old SMS-Activate style SMS-Activate shut down in December 2025 and pointed users to HeroSMS. Treat it as a large catalog service in that same category, not as a guaranteed identical product. Check current pricing, payment methods, and refund rules before depositing.

A number you keep for calls and texts

• Google Voice is the best free option if you’re in the US and already have a US mobile number to set it up. Google says some sites, including banks and subscription services, will not text Voice numbers.
• Hushed or Burner are reasonable paid second lines for listings, dating, or separating work from personal. They are still virtual, so verification is hit-or-miss.
• A cheap prepaid SIM or carrier second line is the most reliable choice when the service must accept the number.

Practical pick

• Strict US signup, one code: start with TextVerified.
• International or low-cost bulk/testing: 5sim (or HeroSMS if you want the post–SMS-Activate marketplace style).
• Everyday second number, not just codes: Google Voice if you can get it; otherwise Hushed/Burner, knowing many verifications will fail.
• Anything financial, government, or long-term: use your real carrier number.

Avoid free public inboxes for anything you care about. And if a code doesn’t arrive, switch providers or number types rather than retrying the same burned prefix.

Short answer

There isn't one "best" service, because platforms disagree about what they'll accept. What actually determines whether a code arrives comes down to five properties of the number, not the brand behind it.

The five things that matter

Per esimpy.com, a number has to be:

• 1.Non-VoIP / carrier-backed. Every major platform blocks VoIP now. Anthropic names VoIP, Google Voice, app-created numbers and landlines explicitly; OpenAI blocks VoIP, landlines and shared numbers; WhatsApp, Telegram, X and Discord do the same. If your number came from an app (Google Voice, TextNow, Skype, Hushed), it's VoIP and it will be refused.
• 2.Private, not a shared public inbox. Free "receive SMS online" sites publish numbers on a public page where anyone can read incoming messages — meaning strangers can see your code and the number has almost certainly already been used on the platform.
• 3.Unused on that specific platform. Platforms cap accounts per number, and the caps differ more than people expect.
• 4.From a supported country. Anthropic, for example, accepts numbers only from supported locations and separately requires you to be physically in one.
• 5.Held for the right duration. One-time numbers live ~20 minutes and suit throwaway signups. Rentals run days to months and suit anything you'd be upset to lose, because many platforms re-check your number long after signup.

Named options in the results

Two providers came up, both marketing themselves on exactly these criteria (worth noting: these are their own pages, so treat the specs as vendor claims):

virtualsms.io — claims real carrier SIMs (not Twilio/Google Voice), 145+ countries, 2,500+ services, one-time codes at $0.05/code and rentals from $0.25/day (1, 3, 7 or 30-day terms, extendable), with automatic refund if no code arrives. They say most codes land in 30–60 seconds and also offer an API/MCP server plus matching-country proxies.

virtsms.com — claims non-VoIP numbers across 190+ countries and 6,800+ services, split into Activations (one-time, refund on failure) and Rent (1–30+ days, unlimited messages on a dedicated number). They quote 10–30 second delivery.

How to judge any provider

The distinguishing questions, again from esimpy.com:

• Does it publish a per-number delivery rate? Numbers rotate through carrier pools and success rates move; live per-number accuracy is the one stat that predicts success.
• Is there an automatic refund when a number fails inside its window? If failure costs you money, the incentives are wrong. (Both providers above advertise this.)
• Is the inbox private to you?
• Are rentals available, not just 20-minute numbers? A provider offering only one-time numbers can't serve the accounts that matter most.
• Can you reach a human? Verification fails in specific, weird ways.

Platform-specific notes

Cost

A working number for a single verification usually runs about a dollar or two depending on country and platform — smaller than most people assume, though not the "few cents" some providers imply.

One caveat worth flagging

Many platforms' terms prohibit verification with numbers you don't own, and Telegram-style accounts where "the number is your login" can be lost permanently if you rent and then let it lapse — or if the provider recycles it. If an account genuinely matters, a rental you control or your own carrier number is the safer bet. Conversely, if the goal is just privacy so your real number stays out of data-broker and spam pipelines, a rented non-VoIP number does that job cleanly.

The best service depends on what you need: for high-volume app verification across many platforms, VirtSMS stands out in the results because it advertises 6,800+ services, 190+ countries, and both one-time OTP and long-term rentals.⁵⁷ For the broadest country coverage in the results, SMS Feel is strongest on paper with 180+ countries, 5,000+ services, and an API for developers.⁶

If you want the quickest practical comparison, here’s how the top options in your results stack up:

A few practical takeaways:

• Choose VirtSMS if your priority is maximum service coverage and a mix of temporary and rental numbers.⁵⁷
• Choose SMS Feel if you care most about country coverage, fast OTP delivery, and developer tooling like an API/SDKs.⁶
• Choose HeroSMS if you specifically want non-VoIP numbers and webhook-based automation.²
• Choose VirtualSMS if you want real carrier SIM numbers rather than cloud/VoIP-style numbers.[?]

One caution: these providers are marketing their own capabilities, so the “best” choice can change depending on whether you need WhatsApp/Google support, a specific country, rental duration, or API integration.⁵⁶⁷²

If you want, I can also rank these for a specific use case like WhatsApp, Google, Telegram, developer API, or lowest price.

When choosing a virtual number service for receiving SMS verification codes (OTPs), the most critical factor is whether the service provides real mobile (non-VoIP) numbers or VoIP numbers.

Most major platforms (Google, WhatsApp, OpenAI, banks, Tinder, Uber) automatically detect and block standard VoIP numbers (like Google Voice or Skype).

Here are the best services broken down by category:

1. Best Overall & Value: SMSPool

• Best for: Everyday verification codes (OpenAI, Discord, Telegram, social media).
• Pricing model: Pay-per-SMS (typically $0.10 to $1.50 depending on the service and country).
• Why it’s great:
• Uses real non-VoIP carrier routes.
• You only pay if the SMS actually arrives; if the code fails to deliver, the balance is refunded automatically.
• Shows real-time platform success rates so you know if a carrier route is currently working before you purchase.

2. Best for Strict US Platforms: TextVerified

• Best for: US-based apps that strictly enforce fraud filters (e.g., US banks, Venmo, Craigslist, dating apps).
• Pricing model: Credit-based, pay-per-verification (slightly more expensive than budget competitors).
• Why it’s great:
• Uses genuine major US mobile carriers (Verizon, AT&T, T-Mobile).
• Extremely high bypass rate for services that reject almost every other virtual number.
• Offers both one-time activations and long-term number rentals.

3. Best for Global Variety & Cheap High-Volume: 5SIM or SMS-Activate

• Best for: Verifying accounts across non-US countries or testing at scale.
• Pricing model: Pay-per-SMS (often as low as a few cents per code).
• Why they’re great:
• Enormous pools of numbers across 100+ countries.
• Massive API support if you need automated registration.
• SMS-Activate also offers rental options if you need a number reserved for days or weeks.

4. Best for Long-Term / Recurring 2FA: MobileSMS.io

• Best for: Keeping the same number active for multiple logins over months.
• Pricing model: Monthly or temporary rentals.
• Why it’s great:
• Provides real SIM card numbers from countries like the US, UK, and India.
• One-time temporary numbers are discarded immediately, meaning if an app asks for SMS verification again later, you will be locked out. Services like MobileSMS.io allow dedicated long-term holding.

Options to Avoid

• Free Public SMS Sites (e.g., Receive-SMS, Temp-Number): These numbers are public, heavily abused, and already blacklisted by virtually all major platforms. Additionally, anyone visiting the website can read your incoming codes.
• Standard VoIP Apps (TextNow, Google Voice, Burner, Skype): While great for regular texting and calls, they are classified as VoIP by carrier databases and will fail on almost any modern verification system.

Recommendation Summary

• For quick, reliable one-off verifications at a fair price: SMSPool
• For stubborn US apps/financial services: TextVerified
• For international numbers on a budget: 5SIM
• For an account you plan to keep long-term: Choose a rental option rather than a disposable one-time activation.

The "best" option really depends on what you need it for, and it's worth noting that many "top 10" lists for this niche (including several in my search results) are published by the services themselves or affiliates ranking themselves #1 — so take glowing claims with a grain of salt. Here's an honest breakdown by use case:

For personal privacy (occasional account sign-ups)

These are established, reputable apps with real user bases rather than SEO-only listicles:

• Google Voice – Free, widely trusted, and commonly used alongside paid alternatives even by reviewers who primarily recommend other tools.

Hushed and Cloaked are also services I use, and I still keep a ported number with Google Voice.

• Hushed – A long-running paid virtual number app.

Hushed offers US, Canadian, UK and Puerto Rican numbers with calling, texting and auto-reply tools. Keep in mind though, verification success depends on the receiving service .

• MySudo – Good if you want multiple separate identities.

MySudo's higher paid plans give you multiple numbers to keep different parts of your life separate.

• Burner – Another well-known disposable-number app often grouped with Hushed and Tossable Digits as outperforming free options for things like Google verification.

For developers / bulk or automated verification (API access)

If you need to programmatically receive OTPs at scale (e.g., for testing or account management tools), the pay-per-number "SMS activation" platforms are the standard choice:

• 5sim.net, SMS-Activate, TextVerified – These are consistently the three names that come up across independent comparisons as the leading options,

ranked by success rate, country coverage, and pricing, tested across 80 verification scenarios in one comparison. TextVerified is generally positioned as the premium, more reliable (non-VoIP) option, while 5sim/SMS-Activate are the budget picks — 5sim.net wins on raw price, while TextVerified leads US-only premium tiers . The trade-off: TextVerified offers higher-quality carrier-grade, non-VoIP numbers that pass stricter platform checks, but pricing reflects that — expect to pay 3-5x more than budget services.

• Twilio is the industry-standard enterprise API if you're building verification into your own product (not mentioned in these consumer-focused results, but it's the dominant business-grade choice for real two-way SMS/voice numbers at scale).

For quick, free, one-off codes

If you just need a number once and don't care about privacy, free public-number sites exist, but understand the trade-offs:

• Sites like **Quackr

Short answer: there isn’t a single “best” service that reliably works everywhere. Whether an SMS verification code will arrive depends mostly on the site or app you’re verifying. Many major services actively reject VoIP/virtual numbers. Two clear, current examples:

• Login.gov explicitly doesn’t accept Google Voice or similar VoIP numbers. (login.gov)
• WhatsApp lists VoIP numbers among unsupported types for registration. (faq.whatsapp.com)

What tends to work best, from most reliable to most flexible

• A real mobile line (postpaid or mainstream prepaid) on a cellular carrier. This has the highest acceptance across banks, government, and big platforms.
• A carrier-connected “second line” app that supports short codes. Example: Sideline says it supports many short‑code messages (but not Telegram/WhatsApp). Reliability is still app‑ and service‑dependent. (support.sideline.com)
• Paid VoIP number apps that acknowledge short‑code limits and document what they support. Examples:
• TextNow: their help center says some verification/short codes won’t work and you must confirm the target service accepts TextNow’s VoIP numbers (paid tiers tend to fare better than free). (help.textnow.com)
• Hushed: can receive some verification codes, but delivery isn’t guaranteed because many senders block VoIP. (support.hushed.com)
• Google Voice: often works for some sites, but you can’t send texts to 5–6 digit short codes, and some services block GV outright. (support.google.com)

Important caveats to know before you pay

• Short codes aren’t universal to VoIP. Even Twilio notes that receiving short‑code SMS on long‑code/virtual numbers isn’t guaranteed, even when local. That uncertainty is why results vary so much across apps. (help.twilio.com)
• Some platforms publish outright VoIP bans (e.g., Login.gov, WhatsApp), and others silently filter by “line type” behind the scenes—so two services can treat the same virtual number differently. (login.gov)

How to choose, practically

• If you need maximum reliability (banks, government, crypto, or anything high‑stakes), use a real mobile number rather than a virtual one.
• If you must use a virtual number:
• Prefer a provider that publicly documents short‑code/verification behavior (not just “supports SMS”).
• Test with the exact service you care about while you’re still within a refund or trial window.
• Expect that WhatsApp/Telegram may not verify on VoIP; Sideline says it won’t work for those specifically. (support.sideline.com)

If you tell me:

• Which service(s) you need to verify,
• Your country/region,
• Whether this is one‑time or ongoing use,

I can recommend the most suitable option (and the lowest‑cost way to test it) for your exact case.

I'll compare the top virtual number services for SMS verification codes.

I've mapped the key trade-offs — now I'll gather specific details to finalize my recommendations.

There is no single best — it depends if you want to receive a code for yourself vs. send codes as a business, and if the site blocks VoIP.

1. The key rule: VoIP vs. non-VoIP

A VoIP number lives on the internet (Google Voice, TextNow, free "receive SMS online" sites). A non-VoIP number is a real mobile number on a carrier's network. Apps like Telegram, WhatsApp, and Google block VoIP because spammers abuse it

• A VoIP number is a phone number that lives entirely on the internet. It isn't tied to a physical SIM card or a mobile carrier's network

• Google Voice, TextNow, most free "get a free number" apps, and the vast majority of free public "receive SMS online" websites all hand out VoIP numbers

• A non-VoIP number, also called a mobile or real number, is issued by an actual mobile carrier and backed by their network, the same way the SIM in your phone is

Platforms like Telegram, WhatsApp, Instagram, Tinder, Google, and Discord started refusing them [VoIP].

Skip if: Skip throwaway SMS receiver sites for any service you plan to keep using; Google, Telegram, and banking apps now flag those number ranges and refuse to send codes

Public ranges have been mass-blocked by every major service since around 2023. Even when a code does come through, sharing a public number means anyone refreshing the page can read it.

Important: Never use a public SMS-receiver website for any account you plan to keep. The number is shared with everyone reading the page, the code shows up publicly, and the service you signed up for will flag the account on the next risk review.

2. Best if YOU need to receive a one-time OTP

For strict verifications — WhatsApp, Telegram, Google, TikTok, Facebook, banks — you need a paid, private, non-VoIP / SIM-based activation, not a free VoIP app.

Top options in this category:

• SmsPva, SMS-Man, Grizzly SMS, PVAPins, SMSActive, eSIMpy
• SmsPva provides temporary phone numbers for receiving SMS verification codes online without using your personal number. The platform offers both real SIM-based numbers and virtual numbers from more than 60 countries, making it suitable for WhatsApp, Telegram, Google, TikTok, Facebook, and hundreds of other services

• With over 1,550,000 users and pricing starting from $0.05

• SMSActive.com provides high-quality, private, and secure temporary phone numbers from over 100+ countries

• PVAPins offers numbers from over 200 countries, including Australia

How to pick: filter by the app you're verifying, it only shows numbers confirmed to work with that specific service. A high accuracy rating is a strong proxy for "this is a clean, non-VoIP number the app accepts".

My pick for one-off privacy signups: PVAPins / SmsPva / Grizzly — pay $0.10-$0.30 per OTP, use once and throw away.

3. Best for a long-term 2nd number for everyday verification

The pick: Google Voice remains the strongest free option for US users, with a permanent personal number tied to your Google account

• Google Voice gives US Google accounts a free permanent phone number that handles SMS, voicemail, and forwarding
• New Voice numbers require a US-billing Google account and a US-routable forwarding number at first setup
• Most major US banks accept Voice numbers for verification, but a smaller subset (typically credit unions and some neobanks) still flag VoIP

Runner-up: TextNow is the best free alternative for users outside the US, with carrier-grade delivery and a long-lived number that works for most major services

• TextNow stayed the most reliable free option for non-US users, with numbers from the US and Canada that pass the major verification flows
• The number is reclaimed if you stop opening the app for thirty days, but TextNow Premium at $9.99 monthly removes both limits

US users get the best free deal with Google Voice. Non-US users land on TextNow for a reliable free number or Hushed for short-lived international numbers

4. Best disposable / burner for short-term privacy

• Hushed sells week-long, month-long, or longer numbers in dozens of countries on a pay-as-you-go basis. The minimum credit pack is $4.99
• Burner has a similar model in the US and Canada at $5 monthly for a single line. Both handle most verification flows but Hushed is the broader international option
• Burner provides disposable numbers that self-destruct after usage with advanced privacy controls

Warning: Treat these as second-tier when you want a number you can throw away cleanly. Major banking apps and some government portals refuse Hushed and Burner number ranges

5. Best if YOU are a developer sending verification codes

Twilio and Plivo are the right answer if you are building software that needs programmable phone numbers, not just receiving codes by hand

Pay-as-you-go pricing starts at $1.15 monthly per US number plus per-message costs

2026 pricing comparison:

• For most teams in 2026: Twilio Verify is the most complete verification API (at a premium: $0.05 per verification plus channel fees), Plivo Verify is the value pick (no verification fee — you pay only ~$0.008 per US SMS)
• Telnyx ~$0.005/SMS, Plivo $0.00550/SMS, Vonage $0.0079/SMS, Twilio $0.0079/SMS

Do not buy a Twilio / Vonage / Plivo VoIP number to receive third-party OTPs yourself — those are often blocked as VoIP for WhatsApp, banks, Google. Use them to send OTPs to your own users.

Bottom line:

• One strict OTP (WhatsApp/Google/bank/crypto): paid non-VoIP activation — SmsPva, PVAPins, Grizzly
• Free long-term US 2nd number: Google Voice
• Free long-term non-US: TextNow
• Paid throwaway international: Hushed, US/CA throwaway: Burner
• Business API to send codes: Twilio Verify for completeness, Plivo / Telnyx for cheapest
