Does AI name Quackr?

It depends on whether you need a number for a one-time verification code or a standing second number you'll keep using.

Quick comparison

My recommendation

For verifying an account (WhatsApp, Google, Telegram, etc.): go with verifynumber.io if the platform is one that tends to reject virtual numbers — its whole pitch is carrier eSIM numbers that pass checks that standard VoIP lines fail, and it publishes per-platform success rates (e.g., 100% for Google/Gmail, 99% for Amazon/AWS, 99% for Apple ID). If you just need something cheap and fast and the platform is lenient, numberotp.com is the lighter option: 1,500+ supported services, numbers assigned in ~3 seconds, a few cents per activation, and $0.10 in free credits to test it.

For an ongoing number — receiving calls, texting people back, keeping a line separate from your real one: use burnerapp.com. The OTP services are explicitly disposable; numbers expire after use, so they're useless for anything you need to log back into later.

Caveats worth knowing

• These are vendor claims. Success-rate figures and "non-VoIP" assertions come from the services' own marketing pages, not independent testing.
• One-time numbers can't recover an account. If you verify with an expiring number and later get locked out, you may lose access permanently. For anything important, use a number you control long-term.
• Terms of service. Many platforms prohibit virtual/disposable numbers for verification. Check the rules before you rely on one, and don't use this for anything involving financial or identity verification where a real number is required.
• Pricing. numberotp.com quotes a few cents per activation with the price shown before you confirm; verifynumber.io doesn't list pricing on the page above, so check before committing. burnerapp.com is a subscription rather than per-use.

It depends on what you need the number for. There isn’t one best service for every case.

Calls and texts (privacy, selling something, dating, short projects)

These are the usual picks:

• Google Voice — Best free option if you’re in the US and can verify signup with a real mobile number. Good for a lasting second line. It is VoIP, so many apps and banks reject it for verification.
• Burner — Best when you want a number you can delete when you’re done (marketplace listings, one-off contacts). US/Canada, paid, with short trials. Often recommended for true temporary use.
• Hushed — Good if you want short prepaid windows (including multi-day passes) or numbers outside just the US. Paid.
• TextNow — Free with ads for basic calling and texting. Numbers can be reclaimed if you go inactive, and verification success is inconsistent.

PCMag and similar roundups consistently point at Burner, Hushed, and Google Voice for this kind of second-number use. [¹](pcmag.com/how-to/burner-second-phone-number-...) [²](pcmag.com/how-to/i-set-up-a-burner-phone-num...)

One-time SMS codes only

• Avoid free public “receive SMS online” sites for anything that matters. Those inboxes are shared; anyone can read the code, and major apps often block the numbers. Use them only for throwaway, low-stakes signups you will never need again. [³](securitysenses.com/posts/temporary-phone-num...)
• Paid private numbers (for example TextVerified-style non-VoIP rentals, or similar per-code services) work more often on strict apps because the number isn’t public and is less likely to be flagged as VoIP. They cost a small amount per code or rental, and success is still not guaranteed.

Practical limits

• Don’t tie banking, crypto, government, or any account you need to recover to a temporary number. The number can expire or be reassigned, and you can lose the account.
• Many platforms block virtual/VoIP numbers on purpose.
• Using a temporary number for privacy is generally fine. Using one to commit fraud, spam, or evade bans can violate the law and the other service’s terms.

If you say whether you need calls, a few days of texts, or just one verification code—and which country—the recommendation can be narrowed further.

The best service depends on what you need the number for—whether it is a one-time SMS verification code, a temporary line for calling and texting (e.g., Craigslist or dating), or a long-term secondary number.

Here is a breakdown of the best options by use case:

1. For One-Time SMS Verification (Signing up for apps)

Many platforms (like WhatsApp, Uber, or social networks) block standard VoIP numbers. These services specialize in providing real mobile numbers for verification codes.

• TextVerified (Best for US services):
• Uses non-VoIP (real carrier) numbers, so it rarely gets rejected.
• Pay-as-you-go credits per verification.
• SMS-Activate (Best for international coverage):
• Huge global selection of countries and platforms.
• Extremely cheap (often a few cents per code).
• 5SIM:
• Similar to SMS-Activate; useful alternative if a specific country or service is out of stock.

2. For Privacy, Selling, or Dating (Calls + Texts)

If you need a functional second number that you can keep for a few days, weeks, or months to talk and text without sharing your real identity.

• Burner (iOS & Android):
• The gold standard for disposable numbers in the US/Canada.
• Lets you create a number, use it, and "burn" (delete) it whenever you want.
• Offers a 7-day free trial, then subscription-based.
• Hushed:
• Very flexible pricing: offers prepaid 3-day, 7-day, or 30-day packages without recurring subscriptions, as well as lifetime deals.
• Supports numbers from the US, Canada, and the UK.
• Cloaked:
• A privacy-first identity manager that generates working throwaway phone numbers and emails on demand, auto-forwarding messages to your real phone.

3. For Free or Long-Term Use (VoIP)

• Google Voice (Best free option, US only):
• Free calling and texting to US/Canada numbers.
• You can keep the number indefinitely as long as you use it periodically.
• Note: Requires an existing US mobile phone number to set up, and some strict verification services reject it because it is VoIP.
• TextNow:
• Free calling and texting supported by ads.
• Can be kept active as long as you send a message or make a call regularly.

4. For Completely Free, Throwaway Public SMS

If you don't care about privacy and just need to bypass a low-stakes website.

• Quackr.io or Receive-SMS-Online.info:
• Free, no registration required.
• Warning: The inboxes are completely public. Anyone on the internet can see the SMS codes sent to these numbers. Never use them for banking, personal accounts, or anything sensitive.

Summary Recommendation

• Need a quick 2FA code that works reliably? $\rightarrow$ TextVerified or SMS-Activate.
• Selling on Facebook Marketplace or going on a blind date? $\rightarrow$ Burner or Hushed.
• Want a free second line for long-term use? $\rightarrow$ Google Voice.

It depends on what you need the temporary number for. For SMS/OTP verification, services like SMSFAST, NumberOTP, VerifyNumber.io, 5SIM, and TextVerified are built for receiving codes; for calls/texts as a short-term second line, apps like Burner, Hushed, or MoreMins are more appropriate.^9117127

A practical way to choose:

• Best for one-time verification codes: SMSFAST or NumberOTP. SMSFAST says it offers free temporary numbers across 190+ countries with instant SMS delivery and no sign-up required,⁹ while NumberOTP says it provides real non-VoIP numbers for 190+ countries and supports 1,500+ services.²
• Best for a short-term private number with calls/texts: Burner, Hushed, or MoreMins. Burner is designed for privacy and offers unlimited calls/texts,¹⁷ Hushed offers a second number for calling and texting starting at $6.99,¹² and MoreMins offers temp numbers in 50+ countries with free incoming SMS and calls.¹
• Best for longer rental or business use: TextVerified or a virtual-number service like 1001SMS. TextVerified says its numbers can be rented for 1 to 14 days for SMS and voice verification,⁷ and 1001SMS positions itself as a platform for temporary numbers, virtual numbers, and eSIMs in one account.²

If you want the simplest recommendation:

• Use SMSFAST or NumberOTP if your goal is receiving OTP codes.⁹²
• Use Burner or Hushed if you want a temporary private phone line for calls and texts.¹⁷¹²

One important caveat: many platforms block or flag temporary or VoIP numbers, so a provider’s “works with X app” claim is not guaranteed in every case.²⁷

It really depends on what you need the number for. Here's a quick breakdown based on common use cases:

For a one-time SMS verification code (free, low stakes)

If you just need to receive a single code and don't care about privacy or reliability long-term: - If you just need a number for one verification code and nothing else, a free receive-only service like Quackr or Temp Number will do—no need to pay for an app .

• Keep in mind these free shared numbers are public —

Quackr also offers premium private numbers for users who need a dedicated number that only they can access, since free numbers are shared and messages are publicly visible . - Free shared temporary numbers don't work for things like WhatsApp verification since WhatsApp blacklists them, but a private, non-VoIP number works because the platform can't distinguish it from a regular carrier SIM .

For a real, functional number you'll use for a while (dating, selling online, short projects)

• Burner is a popular pick:

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 best for marketplace selling, dating, short-term projects, or anyone who wants a real temporary number with full functionality . It also lets you delete numbers instantly when no longer needed, providing complete control over your privacy .

• Hushed is similar but with more flexible pricing:

it offers 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 . It's also strong for international numbers: Hushed offers temporary phone numbers in a wide range of countries and prioritizes security by encrypting calls and messages .

For a free, permanent-ish second number (don't need deletion/privacy)

• Google Voice:

if you just need a free second number for basic calling and texting and don't care about deleting it later, Google Voice works — think of it as a permanent second number you happen to use temporarily . It's best for people who want free and don't need deletion, privacy, or verification, and it's completely free .

• TextNow:

gives you a free number with ads, unlimited texting and calling with no subscription required — the trade-off is ads, VoIP-based calling (which can cause verification issues), and number recycling if you don't use it regularly .

For developers/OTP automation at scale

• NumberOTP:

provides private, non-VoIP virtual numbers that work on WhatsApp, Telegram, Gmail, Instagram, and any platform that accepts real carrier numbers, available in 150+ countries with instant activation , and developers can use its SMS API to automate number provisioning and OTP reading .

My recommendation: For quick, casual verification → try Quackr (free). For a real number you'll actually use for a while → go with Burner or Hushed. Let me know your specific use case (dating app, marketplace selling, business, international, developer/API) and I can narrow it down further.

I'll search for top temporary phone number services to compare options.

I found some promising leads. Now I'll open detailed pages to gather specifics for comparison.

There is no single best - it depends on what you need the number for:

1. Quick decision guide

If you want a free, long-term 2nd number for calls + texts: Use Google Voice or TextNow.

• Google Voice is described as a trusted choice for a free, long-term U.S. phone number backed by Google, to make and receive calls, send texts, and access voicemail from any device.
• It integrates with Gmail and Google Calendar and includes voicemail transcription, call forwarding, spam filtering, and multi-device sync.
• Limitation: Free U.S. number only, requires a Google account, U.S. only and limited international support.

• TextNow is one of the most popular apps for a free U.S. or Canadian number, allowing unlimited texts and Wi-Fi calls without a SIM.
• It also offers voicemail, call forwarding, and cross-device sync on iOS, Android and web.
• Limitation: ad-supported, only U.S. or Canadian numbers, and inactive numbers may be recycled.

At a glance from 2026 comparisons: TextNow = free calling & texting, Google Voice = long-term second number.

If you want a true disposable / burner number for dating, marketplace, freelancing: Use Burner.

• Burner is the go-to app when you need a quick, disposable phone number for privacy or short-term use like Craigslist, dating apps, or keeping your real number private.
• You can create multiple temporary numbers, each with its own inbox for texting, calling and voicemail, then “burn” it when done.
• Burner is a virtual phone number app designed for situations where not every number needs to be permanent.
• Compared to Google Voice: Google Voice is free and tied to a Google account for a single, permanent number, while Burner is a paid service designed for flexibility, multiple numbers, short-term use, and clearer separation.
• Burner supports multiple active numbers on one device and includes features like auto-replies to keep lines organized.

Burner is generally trial/paid, not free for continued use, while TextNow and TextFree offer free second numbers.

If you want cheap one-off / occasional use, including non-U.S. numbers: Use Hushed.

• Hushed is listed alongside Burner as Trial/paid Temporary numbers for calls + SMS, best for private temporary numbers.
• Hushed is a mobile app that provides additional numbers for calling and texting, often used for occasional or short-term needs.
• Compared to Google Voice, Hushed is more focused on temporary or ad-hoc numbers rather than a single long-term number tied to an account.
• Paid apps like Burner or Hushed offer secure short-term numbers, while Google Voice provides a permanent virtual number.

2. Very important: free numbers often fail verification

If you need the number to receive an OTP from WhatsApp, Tinder, banks, Stripe, PayPal, etc., do NOT use free public "receive SMS online" sites or free VoIP apps.

• Free temporary numbers are virtual numbers generated using VoIP technology, usually accessible via websites or apps, with some services displaying received messages publicly.
• Messages on free numbers can be publicly visible, many services block temporary numbers, and recycled numbers can leak earlier messages.
• Free public burner sites issue numbers shared across thousands of strangers, almost always tagged as VoIP, and routinely rejected by WhatsApp, Tinder, banking apps, and Stripe.
• Specifically: TextNow, TextFree, Hushed in free mode, 2ndLine issue VoIP-flagged numbers from ranges that Stripe, PayPal, Venmo, Bumble, Tinder, and most banks reject.

For that use-case you need a real U.S. mobile, non-VoIP number assigned only to you, for example:

SLYNUMBER - provisions every number through the regulated North American Numbering Plan as a real U.S. mobile line, assigned only to you.

• It serves 200,000+ users across 150+ countries, starts at $4.99/month, and encrypts calls and SMS with TLS and SRTP.
• Comparison table claims: Real U.S. mobile number Yes for SLYNUMBER vs No for Google Voice, SMS verification Yes vs Limited, Starting price $14.99 / 3 months vs Free.
• Recap: SLYNUMBER passes SMS verification for WhatsApp, banking, Tinder, Instagram, while Google Voice is free but VoIP-flagged and fails many verifications, and burner apps at $2-$5/week are often blocked by high-trust services.
• Plans start at $4.99 per month on quarterly billing ($14.99 billed every three months), with annual $49.99/year also available.

My recommendation for you

• Just need to avoid spam for signups, dating, Craigslist / Facebook Marketplace, freelancing? -> Burner if you are in the U.S./Canada and want to burn numbers, Hushed if you want cheap one-offs or international numbers.
• Want a free permanent 2nd number and live in the U.S.? -> Google Voice. Want free without a carrier link? -> TextNow.
• Need to pass SMS verification for a bank, WhatsApp, Instagram, Tinder? -> Pay for a real-mobile provider like SLYNUMBER, not a free public inbox.

Do you want me to narrow it down? Tell me:

• 1.U.S. or other country?
• 2.Calls + SMS or SMS-code only?
• 3.Free only, or OK to pay a few dollars?

There’s no single “best” virtual SMS service — it depends on whether you need one-time OTP codes, long-term number rental, non-VoIP numbers, API access, or the cheapest global coverage. Based on the search results, these are three strong options:

SMSPin is a good pick if you want the broadest country/app coverage and low-cost one-off verifications. It advertises 210+ countries, 10,000+ apps, numbers from $0.01, and an automatic refund if a code doesn’t arrive. It also publishes measured delivery rates, e.g. Pakistan and UAE at 100%, Vietnam and Philippines at 97%, and US/UK at 89% over the last 30 days smspin.io.

VirtSMS is worth considering if you specifically want non-VoIP numbers, which can mean better success rates and fewer blocks. It supports WhatsApp, Telegram, Google, and 6,800+ services across 190+ countries, with both one-time activations and long-term rentals from 1 to 30+ days. Most codes arrive within 10–30 seconds, and crypto payments are supported virtsms.com.

VirtualSim is a strong option if you need API integration or longer number retention. It covers 180+ countries and 2,400+ services, with prices starting around $0.01 depending on service/country — for example, it lists Telegram from $0.12 and WhatsApp from $0.02, though actual country prices vary. It offers an sms-activate-compatible interface, rental up to 180 days, and refunds if you cancel or the number fails virtualsim.io.

Quick recommendation:

• Cheapest/global one-time SMS: SMSPin smspin.io
• Non-VoIP, higher success rate: VirtSMS virtsms.com
• API/scripting + long-term rent: VirtualSim virtualsim.io

Before using any of them, check the target platform’s terms of service — some apps restrict virtual or VoIP numbers, and numbers can still be blocked depending on the route.

The “best” service depends on whether you need a one-time code, a short rental, or a lasting second number you can call and text from. Reliability also varies a lot by the app or site you’re verifying—many block VoIP and known virtual ranges.

Ongoing second number (calls + texts)

These are better for a private line you keep, not one-shot verification.

For a small business line with calling features, look at services like OpenPhone or Grasshopper instead of consumer burner apps.

One-time or short-term SMS verification (OTP codes)

These rent a number long enough to receive a code (or for a few days). Success is higher when the provider uses non-VoIP / real carrier numbers, but stock and acceptance change constantly.

• TextVerified — Long-running option focused on US numbers, often described as non-VoIP. Better suited to stricter platforms than generic VoIP, but more expensive, and user reviews are mixed on refunds and failed attempts.
• SMSPool — Frequently recommended for a balance of price, coverage, and reliability, including non-VoIP options. Good default to try for one-off codes.
• 5SIM — Large country and service catalog, competitive pricing, crypto-friendly. Reliability varies by route; budget for retries.
• SMS-Man and OnlineSIM — Useful alternatives for international numbers and longer rentals.

SMS-Activate shut down in December 2025. Sites still using that name are not the original service—treat them cautiously.

What to avoid for anything important

Free public “receive SMS online” sites (shared inboxes) are poor choices for accounts you care about. Messages are visible to anyone, numbers are heavily reused, and major platforms often block them. Use them only for low-stakes testing.

Practical tips

• VoIP vs non-VoIP matters. WhatsApp, Google, banks, and many fintech apps often reject VoIP (including Google Voice and many free apps) before a code is even sent. Non-VoIP numbers cost more and still aren’t guaranteed.
• Prefer auto-refunds. Choose providers that credit you automatically if no SMS arrives within the window.
• Most reliable option for critical accounts: a cheap prepaid SIM or eSIM from a real mobile carrier. Virtual services are convenient but easier to block.
• Terms of service: Many platforms forbid virtual or temporary numbers for signup. Accounts created this way can be limited or banned.
• Privacy: Private paid numbers beat public inboxes. None of these hide you from law enforcement if payment or account details are traceable.

If you say whether you need a one-time code, a number for a few days, or a long-term second line—and which country or app—it’s easier to narrow this further.

The best virtual phone number service depends on what you need: business SMS, one-time verification, or free/shared temporary numbers. For reliability and ongoing use, paid providers like RingCentral, Twilio, Google Voice, and Sonetel are stronger choices; for quick SMS verification, services such as VirtualSim, VirtSMS, SMSPin, 5SIM, and Onlinesim are built specifically for receiving codes.^{1471011121415}

Here’s the practical breakdown:

If your goal is account verification, the most useful options in the results are VirtualSim, VirtSMS, SMSPin, 5SIM, and Onlinesim because they are explicitly designed for receiving OTPs and one-time codes.^1231215

If your goal is reliable long-term use, the stronger picks are Twilio, RingCentral, Google Voice, and Sonetel, since they are positioned more as standard virtual phone or business communication services rather than disposable verification tools.¹⁴⁷¹⁴

A few important caveats:

• Shared public numbers can be risky because incoming SMS may be visible to others; Multilogin notes this for services like receive-smss.com and similar public inbox sites.³
• Some verification platforms advertise non-VoIP numbers or higher success rates, which can matter for services that block standard VoIP numbers.²¹⁰
• For business or recurring SMS, a paid provider is usually more stable than a free public inbox.¹⁴¹⁴

If you want, I can also narrow this down to:

• best free options
• best for WhatsApp/Telegram
• best for business use
• best by country

The best virtual phone number service depends heavily on what you need the SMS for. Services differ greatly depending on whether you need a quick verification code (OTP), a permanent business number, a private second line on your smartphone, or an automated developer API.

A critical factor to understand is VoIP vs. Non-VoIP (Real SIM): Major services (like Google, WhatsApp, OpenAI, Tinder, and banks) often block standard VoIP numbers. If you need SMS for account verifications, you usually need services offering non-VoIP / real carrier numbers.

1. Best for OTPs & Account Verification (Non-VoIP / Real SIMs)

If you need a number strictly to bypass phone verification checks on apps that block VoIP numbers:

• SMSPool: One of the most popular and cost-effective services specifically for SMS verification. It routes through real SIM cards rather than VoIP, giving it a very high success rate for services like OpenAI, Telegram, and Discord. You only pay per successful code received (often $0.10 – $1.00 depending on the service).
• TextVerified: The gold standard for US-based real carrier numbers. It offers both short-term one-time verifications and recurring rentals. Excellent success rate with strict platforms like Uber, Tinder, and banking apps.
• DaisySMS: A cheaper, highly reliable alternative to TextVerified that also uses real US physical SIM lines. Works seamlessly with most verification systems.
• SMS-Activate / 5SIM: Massive global platforms supporting numbers from over 100+ countries. Extremely cheap, though number quality can vary by country and carrier.

2. Best for Long-Term Personal Use (Second Line / Privacy)

If you want a dedicated private second phone number on your smartphone to receive texts and calls continuously:

• Google Voice:
• Cost: Free (for personal US accounts).
• Best for: Standard communication, craigslist ads, signups that accept VoIP.
• Downside: Many services (banks, rideshares, OpenAI) detect it as VoIP and will reject it for SMS verification.
• Hushed:
• Cost: Flexible prepaid plans or lifetime subscriptions (often on sale).
• Best for: Private second numbers in the US, UK, and Canada. Supports both calling and SMS/MMS without tying back to your personal identity.
• Burner:
• Cost: Subscription-based (~$5–$10/month).
• Best for: Disposable or semi-permanent US/Canadian lines with features to auto-delete or "burn" numbers when you no longer want them.

3. Best for Business & Team Collaboration

If you need a stable, professional virtual number to manage customer support, team inboxes, and business texting:

• OpenPhone: The industry favorite for startups and modern businesses. It provides US/Canadian virtual numbers, an intuitive desktop and mobile app, shared inboxes, and integrations with Slack/HubSpot.
• Zadarma: Ideal for international virtual numbers. It covers 100+ countries and offers virtual SMS-enabled numbers with cloud PBX features at competitive rates.
• eVoice / Grasshopper: Established virtual phone systems best suited for small business owners who want toll-free or local numbers with multi-extension call and SMS forwarding.

4. Best for Developers (APIs & Automation)

If you are building an application and want to programmatically receive SMS via webhooks:

• Twilio: The industry standard. Offers global numbers, highly reliable webhooks, and exhaustive documentation.
• Telnyx: A direct, slightly more cost-effective alternative to Twilio with private global IP networking and full SMS API capabilities.
• Plivo / Vonage (formerly Nexmo): Great scalable alternatives for developer-focused international SMS delivery and reception.

5. Best Free Temporary SMS Services (Public Inboxes)

If you just want to register for a casual forum and don't care about privacy:

• AnonymSMS, Receive-SMS-Free.cc, or SMS-Receive.net:
• How it works: You pick a public number from a website, trigger your SMS, and watch the public feed for your code.
• Warning: Anyone can see these messages, numbers are reused frequently, and major apps (Google, WhatsApp, PayPal) have already blacklisted almost all of these public numbers. Never use them for sensitive accounts.

Summary Recommendation:

• For app verification/2FA (WhatsApp, Discord, OpenAI): Choose SMSPool or TextVerified.
• For a permanent second line on your phone: Choose Hushed or Google Voice.
• For business/team SMS: Choose OpenPhone.
• For software integration/APIs: Choose Twilio or Telnyx.

Best Virtual Phone Number Services for Receiving SMS

Based on current comparisons, here's a breakdown by use case:

For Free/Personal Use

Google Voice remains the go-to free option for US residents. It gives US residents a free, permanent virtual SMS number and supports calls and SMS messages from any device with a Google account.

Most account verification sites accept it.

TextFree and TextNow are solid free alternatives. They give you a real US phone number on the free tier, support SMS and calling over Wi-Fi or data, though the trade-off is ads inside the app — best for light personal use only.

For Privacy-Focused Use (Dating Apps, Marketplaces, etc.)

MySudo, Hushed, and Cloaked are top picks in this category. MySudo offers one, three or nine phone numbers depending on the paid plan, useful for keeping different parts of your life separate.

Hushed offers US, Canadian, UK and Puerto Rican numbers with calling, texting and auto-reply tools , while Cloaked lets you create separate contact identities with numbers and email aliases, plus communication controls and optional forwarding.

For One-Time Verification Codes (OTP/SMS Verification)

If you just need a quick, disposable number for a single verification code, several specialized services stand out:

• Quackr –

a privacy-first virtual phone number platform that allows you to receive SMS verification codes instantly without sharing your real number, supporting multiple countries including the US, UK, and Germany, with no registration required.

• SMSPool –

a web-based service that provides virtual numbers specifically for SMS verification , with pay-per-verification pricing, numbers from 30+ countries, and API access for developers.

• Receive-smss.com – praised for simplicity:

you click a number and start receiving texts and that's it, with no logins or nonsense.

For Business Use (Team Messaging, CRM Integration)

CallHippo is a strong business pick. It's a virtual phone number provider with SMS built in, supporting two-way messaging, CRM sync, and shared team inboxes, with numbers in 150+ countries available within minutes, and plans starting at $0 per user per month.

RingCentral is also widely recommended, especially for privacy and verification needs. It's a great way to protect your privacy, allowing you to receive SMS codes reliably while keeping your personal number hidden, and is intuitive and efficient for both beginners and professionals.

EZ Texting is another strong business contender — a powerful service that tackles SMS verification and bulk messaging with ease, giving access to multiple virtual numbers from different area codes, which is essential for segmenting SMS use cases.

Quick Recommendation Summary

A note of caution: Free temporary/shared numbers (like those from Quackr, Anonymous SMS, or similar public pools) are convenient but less reliable — free shared numbers may occasionally fail on some platforms , and many virtual phone number apps rely on VoIP numbers, which can fail on stricter platforms

I'll search the web to compare the top virtual SMS services and their current features.

I've found some promising leads — now I'll open the detailed pages to verify the specifics.

Best virtual numbers for receiving SMS — pick by use case

There is no single best service. Paid carrier-grade numbers work for business and verification, while free apps work for low-risk personal use but often fail verification.

Free numbers exist but fail on anything that depends on delivery like SaaS verification or sales outreach, for real work you want a paid number from a vendor with carrier relationships.

1. Best for business teams: Quo / OpenPhone

Quo, formerly OpenPhone, for team-shared business line with Slack and HubSpot integrations, $19/user/month.

• Starter $19/user/month, Business $33/user/month
• Real US/Canada carrier numbers, not VoIP-flagged
• Best feature is shared inbox so whole team sees calls and texts
• Works on most services since numbers are carrier-grade
• 7-day free trial, no card required

Cybernews also lists Quo for small businesses at $19/month per user with VoIP, call forwarding, routing, voicemail-to-text, multiple numbers and toll-free numbers.

Alternatives at scale:

• KrispCall at $15/user/month with unified callbox, bulk SMS and custom caller ID
• Dialpad at $27/month per user for sales teams and call centers
• Business SMS now requires STIR/SHAKEN caller ID authentication and A2P 10DLC registration for business SMS.

2. Best for developers / API receiving: Twilio, Vonage

Twilio for programmatic SMS/voice with $0.0085 per SMS, pay-per-use, no monthly commitment.

• Roughly $1/month per US number plus $0.0085 per SMS
• Twilio is API-first, not a phone app
• Developer SMS testing use case is listed as Twilio, Vonage at $0.0085/SMS pay-per-use API, no monthly fee
• Other US pricing reported as local/10DLC number $1.15/month; toll-free $2.15/month

Vonage:

• Vonage outbound SMS from US local at $0.00809 per segment, with inbound around $0.00649
• Listed together with Twilio for developer SMS testing and OTPs, notifications and programmable voice/SMS integration.

Use these if you need to receive SMS into code via webhook, queue or database, not a human inbox.

3. Best free for personal US use: Google Voice

Google Voice still gives free US numbers tied to a Google account, works on Android, iOS, web.

How it works:

• Visit voice.google.com and sign in with Google account, then select a number by area code or city
• Must link it to an existing US mobile or landline number that receives a verification code
• Can receive and send SMS verification codes, make/receive calls, and get free voicemail transcription
• Completely Free, listed as Free with $16.30/month per user for businesses

Limits:

• US-only, requires a US-based account
• Many fraud-sensitive services detect and reject Google Voice numbers as VoIP
• Some banks, government services or 2FA short codes may not reliably send to Google Voice because services block virtual numbers
• Not intended for emergency calls and does not support 911 services
• Must use it within a rolling nine-month period or number can be reclaimed

Best for: second line, one-time signups, newsletters and separating personal from public use. Skip if you need bank or government SMS-2FA.

4. Best free ad-supported alternative: TextNow

TextNow for low-volume burners, but both Google Voice and TextNow fail on services that block VoIP for verification.

• Primarily focused on unlimited SMS capabilities within the US and Canada over Wi-Fi or data, without contract or monthly fee
• Accessible on iOS and Android smartphones and tablets, plus a web-based platform to send and receive from browser
• Setup is sign up with email, choose US area code, receive new dedicated US number instantly
• Listed as Free with one-time fee of $4.99 for SIM card, with unlimited calling/texting and voicemail transcriptions

Many popular VoIP services like Google Voice, TextNow, Burner, Hushed, RingCentral, DialPad, OpenPhone, Nextiva and Vonage don’t support SMS-based 2FA in all cases due to routing and verification reasons.

5. Best cheap disposable burners: Hushed, Burner, MySudo

Hushed or MySudo for personal burner, low monthly cost for marketplace listings, dating apps and signups you do not want tied to real number.

• Hushed sells short-term numbers for $1.99 for 7 days or $4.99/month for unlimited
• Also listed as $3.99 prepaid / $4.99/month subscription with multiple numbers, international calling and voicemails
• MySudo bundles up to 9 personas, numbers + emails + handles, at $2-15/month
• Both are app-based on iOS, Android and web, but services with strong anti-VoIP filtering like banks and government portals will reject them
• Burner for disposable phone numbers at $4.99/month with 7-day free trial, multiple numbers and spam blocking
• For temporary privacy: Burner/Hushed/TextNow.

Use for Craigslist, Facebook Marketplace, dating, trials and spam shielding. Do not use as sole 2FA number for bank.

6. Best for privacy persona: Surfshark Alternative Number

• Privacy, security and anonymity use case at $18.44–$20.44/month
• Service itself costs $2.99/month to $4.99/month on top of Surfshark VPN subscription
• Can generate new online persona including name, email and phone number
• Limitation noted: only provides USA numbers and users report you can’t pick area code or initiate texts/calls in some setups.

7. Best temporary OTP / activation numbers: SMS-Activate, 5SIM, SMS-Man, Temp Number

For one-time verification codes without long-term rental:

• Temporary virtual numbers for receiving verification messages and OTP codes, with platforms such as 5SIM, SMS-MAN, and SMS-Activate offering broad international coverage.
• Temp Number is described as disposable numbers for SMS verifications with selection from 180+ countries, instant in-app confirmation codes and privacy focus
• Quackr offers disposable numbers for verification with clean interface for temporary numbers

These are pay-per-code, often $0.01+, and best when Google Voice/TextNow is blocked. Numbers are single-use or short rental.

8. Free public inboxes — use only for throwaway testing

Examples include Receive-SMS-Online, Receive-SMS-Free, FreePhoneNum.com, SMS-Receive.net. Free public numbers are shared inbox where anyone can see your codes.

Why to avoid for anything important:

• Numbers are recycled and rejected by major SaaS verification flows
• Recommendation is to skip free public-receive-SMS sites whose numbers are shared, recycled and burned
• Free options that mostly work are Google Voice for US-only personal use and TextNow for low-volume burners

Never use public inboxes for banking, password reset, crypto or accounts you need to keep.

Quick choice

• Solo business line + SMS customers: Quo/OpenPhone $19/user/month
• App needs to receive SMS via API: Twilio ~$1/mo + ~$0.0085/SMS
• Free second line US: Google Voice if you have US number to verify, else TextNow
• Disposable dating/marketplace: Hushed $1.99/7-day or $4.99/mo
• One-time OTP blocked elsewhere: 5SIM / SMS-Activate / SMS-Man / Temp Number

Finding a completely free phone number to receive verification codes (OTPs) depends on what you are signing up for. Because major platforms (like WhatsApp, Google, banks, and social media) block virtual/VoIP numbers, options fall into two categories:

1. Public Temporary SMS Websites (No Sign-Up, Disposable)

These platforms provide temporary numbers with public inboxes. You simply copy a number, enter it into the app, and wait for the code to show up on the web page.

• Quackr.io: One of the cleanest and most frequently updated disposable SMS services. It offers numbers from multiple countries (US, UK, Canada, France, etc.) and periodically purges old numbers to reduce blocks.
• Receive-SMSS.com: A widely used platform with dozens of public numbers from international carriers.
• AnonymSMS: Similar to Quackr, offers fresh real SIM/mobile numbers periodically to help bypass VoIP filters.
• SMS-Receive.net: A simple, ad-supported site offering temporary numbers across Europe, the US, and Asia.

⚠️ Important Privacy Warning: Public SMS inboxes are visible to anyone on the internet. Never use these numbers for accounts containing personal information, banking/financial data, or anything you intend to keep long-term. Anyone else can use the same number to reset your password.

2. Free Private Virtual Number Apps (Requires Registration)

If you need a private number that only you can access:

• Google Voice (US only):
• Pros: Completely free, private, permanent, and works for many standard verification codes.
• Cons: Requires an existing US carrier mobile or landline number to activate. Many banks and financial services block Google Voice because it is classified as a VoIP service.
• TextNow / TextFree:
• Pros: Free US/Canadian phone number via app (ad-supported).
• Cons: Receiving shortcode verification texts (5- or 6-digit sender numbers used by banks, Uber, Tinder, etc.) is often blocked on the free tier; you usually have to pay a small fee (or watch ads) to "lock in" the number for verification texts.

Why Free Numbers Often Fail

If a service rejects the free number, it is usually due to:

• 1.VoIP Detection: Services like WhatsApp, PayPal, and Telegram use lookup databases (like Twilio or Telesign) that identify virtual numbers and automatically reject them.
• 2.Reused Numbers: Public numbers have often already been used hundreds of times on popular platforms and are blacklisted.
• 3.Shortcode Restrictions: Automated SMS gateways often refuse to send codes to non-carrier (VoIP) lines.

Cheap Alternative (If Free Doesn't Work)

If you cannot get a free number to work, consider one-time non-VoIP activation services (such as SMSPool, 5SIM, or Grizzly SMS). These provide real, physical carrier SIM numbers specifically for one-time verification codes and usually cost between $0.10 and $0.50 per code.

Several providers offer free phone numbers for verification codes, including Textverified, Tell A Bot, Tiger SMS, MobileSMS.io, Quackr, and FreePhoneNum.^31451510

If you want the clearest fit for this exact use case, Textverified explicitly says its free numbers are for receiving SMS verification codes, and Tell A Bot also advertises free temporary numbers for SMS verification.³¹ If you want broader public free-number options, Quackr and FreePhoneNum both provide temporary numbers for receiving SMS online.¹⁵¹⁰

One important caveat: TextFree does not support verification messages on its free plan; it says 2FA texts require a TextFree Plus subscription.²

There are several providers that offer free phone numbers specifically for receiving SMS verification codes. Here are some of the most notable options:

Popular free SMS verification services:

• Quackr.io –

Offers free temporary phone numbers for SMS verification with phone numbers from the USA, UK, India & more.

The numbers are updated every month.

• TextVerified (free numbers) –

Provides free phone numbers to receive SMS verification codes and get free phone verifications for your favorite services.

Their free numbers are from the US and non-VoIP, letting you receive SMS and texts for free with temp numbers.

• SMSOnline –

Offers free temporary phone numbers for SMS verification, letting you complete SMS verification with free temporary numbers for China, USA, India, Japan & more to verify WhatsApp, Google, etc.

No registration is required.

• Tellabot –

Lets you pick a free temporary phone number to receive SMS verification codes online, with numbers that are publicly available and usable to receive free SMS messages from 700+ online services.

• AnonymSMS –

Provides free disposable phone numbers for receiving SMS verification codes, regularly updating its pool with new numbers from various countries.

• SmsBower –

A platform offering free temporary phone numbers to get verification codes for new account sign-ups or social media profiles, with numbers from multiple countries.

A few things to keep in mind:

• 1.These numbers are public/shared — Services like Quackr, Tellabot, and similar sites use shared numbers that anyone can view, so they're best for quick one-time verifications (not for accounts you want to keep secure long-term).

• 1.Reliability varies — Since many people use the same numbers, some may get blocked by certain platforms (like WhatsApp or banking apps) due to overuse.

• 1.For more permanent/private numbers, you'd typically need a paid tier — most of these services (TextVerified, SMSOnline, etc.) offer paid private numbers starting at low costs if the free shared option doesn't work for a specific platform.

If you tell me which specific app/service you're trying to verify (e.g., WhatsApp, Google, a dating app), I can suggest which of these free options tends to work best for that particular platform.

Several providers offer free numbers for receiving SMS verification codes:

• Textverified — offers free non-VoIP US mobile numbers for receiving SMS verification codes. The numbers are shared publicly on a free tier. app.textverified.com
• VirtualWebPhone — provides free US virtual numbers for receiving SMS online from services like WhatsApp, Instagram, Discord, Coinbase, Netflix, and others. No signup is required for public inboxes. virtualwebphone.com
• Quackr — offers free United States temporary phone numbers for SMS verification and OTP activation on platforms like Gmail, Telegram, Discord, and Tinder. quackr.io

Caveat: these free numbers are usually public/shared, so codes can be stolen or already used, and they generally should not be used for banking, payment accounts, or anything tied to your real identity. Some major services also block known public numbers. virtualwebphone.com quackr.io

There isn’t one universal provider—options fall into two groups, and success depends on the service you’re verifying.

Personal free numbers (private inbox)

These give you a number only you control:

• Google Voice — Free permanent US number for eligible users. Setup usually requires an existing US phone number. It works for some verifications (e.g. Telegram, Discord in tests) but many apps and banks block it as VoIP.
• TextNow — Free US/Canada number (ad-supported) that you can get without already having a US line. Useful for calls/texts and some lower-security codes; major platforms often reject it as VoIP, and inactive free numbers can be recycled.
• TextFree — Similar ad-supported free US number; verification success is generally lower and less consistent than TextNow.

Public temporary numbers (shared inboxes)

Sites such as Receive-SMS.app, FreePhoneNum, SMSS.net, and TextVerified’s free tier list numbers you can use immediately with no signup. Incoming SMS appears in a public webpage inbox.

These are free and fast for low-stakes signups, but:

• Anyone can read the messages, so never use them for banking, email recovery, payments, or accounts you care about.
• Many services (Google, WhatsApp, banks, etc.) block these numbers or known VoIP ranges, so delivery is unreliable.

Practical takeaway: For a number you keep, try Google Voice (if you qualify) or TextNow. For a one-time code you don’t mind being public, use a temporary SMS site and expect frequent failures on strict platforms. Paid non-VoIP numbers are more reliable when free options are blocked.

I'll search the web for providers offering free numbers for verification codes.

Initial results point to a few candidates. I'll open the top pages to verify the details.
