Best Options for a Temporary Phone Number

The right service depends on what you need it for:

Free, one-time verification codes (no signup needed)

If you just need to receive an SMS verification code once and don't care about privacy long-term:

• Quackr –

with over 3 million users and 1,000+ five-star reviews on TrustPilot, Quackr is described as the highest-rated temporary phone number service available . Its phone numbers are rotated at least every 30 days and messages are deleted every 24 hours .

• Temp Number –

offers free temporary phone numbers to protect your privacy online, with no registration required . Note: these numbers are designed for receiving SMS only and cannot be used for making or receiving phone calls .

⚠️ Caveat: most free temporary number services are useless for anything beyond the simplest sign-ups, since platforms like Google, Meta, and banking apps have gotten very good at blocking virtual and reused numbers .

Real, functional number you can delete on demand (dating, Marketplace, privacy)

• Burner –

one of the most popular apps for disposable numbers, known for its user-friendly interface; it lets you create multiple numbers for calls, texts, and voicemail, and allows you to delete numbers instantly when no longer needed . Burner's prepaid numbers work well as true "temporary" numbers with a finite lifespan by design .

• Hushed – good if you need international coverage:

it offers temporary phone numbers in a wide range of countries, making it an excellent option for international users .

Completely free, ongoing second number

• Google Voice or TextNow —

if you just want free and don't care much about privacy or deletion . TextNow is one of the most popular apps for getting a free U.S. or Canadian phone number, allowing unlimited texts and calls over Wi-Fi without a SIM card .

Bottom line recommendation

• Just need one OTP/verification code right now, free → Quackr or Temp Number.
• Want a real, usable number you control and can delete later (dating apps, selling items, business use) → Burner is the most well-rounded choice, since

it spans disposable, temporary, and second-number use cases — you can use a prepaid number as a one-time disposable, or run it as a semi-permanent second number you delete when the situation changes .

• Need international numbers → Hushed.

If you tell me your specific use case (e.g., signing up for an app, online dating, avoiding spam calls, business use, or international travel), I can narrow this down further.

The best service depends on what you plan to use the number for (e.g., verifying an account via SMS, calling/texting on marketplace apps, or general privacy).

Here is a breakdown of the best options based on your specific need:

1. For Account Verification & SMS OTPs (Non-VoIP)

*Many platforms (Google, WhatsApp, Tinder, banks) automatically detect and block virtual/VoIP numbers. These services provide temporary access to real cellular/carrier SIM numbers solely to receive verification codes.*

• TextVerified: Best for US-based verifications. You pay per verification (typically $0.50 to $2.50). High success rate for stubborn services.
• SMSPool: Excellent, low-cost option for single-use OTPs with numbers from dozens of countries.
• 5SIM: Popular globally with a massive selection of countries and platforms, ideal if you need a non-US number.

2. For Calling & Texting (Craigslist, Dating, Privacy)

If you need a private secondary number that can make calls, receive texts, and be "burned" (deleted and replaced) when you are done.

• Burner (iOS / Android):
• Best for: Everyday privacy and short-term use.
• Features: Lets you generate temporary US/Canada numbers, set auto-replies, forward calls, and delete the number instantly with a single tap.
• Cost: 7-day free trial, then subscription-based.
• Hushed (iOS / Android / Web):
• Best value for money.
• Features: Offers prepaid short-term plans (7 days, 30 days, or pay-as-you-go) across the US, Canada, and the UK. Often offers lifetime deals online.
• MySudo:
• Best for all-around privacy.
• Features: Allows you to create complete disposable digital identities ("Sudos") with temporary numbers, emails, and even virtual burner payment cards.

3. For Free Secondary Numbers (Calling & Everyday Use)

• Google Voice: Free for US users, highly reliable for calling and texting. (Note: Requires an existing real US phone number to set up initially, and it uses VoIP, so some services may reject it for 2FA).
• TextNow: Offers free US/Canadian phone numbers supported by ads. Good for quick throwaway use, but numbers can expire if inactive.

4. For Quick, Public One-Time SMS (No Sign-Up)

• Quackr.io or AnonymSMS:
• Warning: Anyone can view the incoming text messages on these public pages, and these numbers are frequently blacklisted by major sites. Do not use them for personal, sensitive, or permanent accounts.

Summary Recommendation:

• Need to pass an SMS verification code? Choose TextVerified or SMSPool.
• Need a number for buying/selling, dating, or freelance work? Choose Hushed (for flexible prepaid plans) or Burner (for ease of use).
• Need a free permanent secondary number? Choose Google Voice.

If you want a reliable paid option, use Textverified, MoreMins, or Hushed depending on whether you need a number for verification, short-term SMS/calls, or a longer-term private second line.^2310111516

• Best for SMS verification: Textverified or 1001sms because they explicitly focus on verification codes and temporary numbers for specific services.²¹⁰⁵
• Best for a private second number with calls/texts: Hushed or Burner, since they’re designed as app-based second numbers with calling, texting, and privacy features.¹¹¹⁶[Burner? no result beyond provided search snippet]
• Best for low-cost country-specific temporary numbers: MoreMins, which offers temp numbers in 50+ countries starting at $0.99.¹⁴¹⁵
• Best for free disposable SMS-only numbers: Textverified free numbers, FreePhone.io, SMSFAST free numbers, or quackr.io, but free disposable services are generally less reliable and less private.^1412136179

A practical rule is:

• Need one-time verification code → choose a verification-focused service like Textverified or 1001sms.²¹⁰⁵
• Need privacy for calls/texts over days or weeks → choose Hushed or Burner.¹¹¹⁶[Burner? no result beyond provided search snippet]
• Need cheap international coverage → choose MoreMins.¹⁴¹⁵
• Need free and temporary only → use a free disposable provider, but expect weaker reliability and privacy.¹⁴¹⁷⁹

If you tell me what you need it for—for example SMS verification, calls/texts, or a specific country—I can recommend the best single option.

It depends on what you’re verifying and whether you need a one-off code, a US number, voice verification, or an API.

Quick recommendation

• Best for strict platforms that reject VoIP: verifynumber.io — uses real carrier-backed eSIM numbers, not VoIP. It claims high success on platforms like Google, Apple, Amazon, and Coinbase, and supports 90+ services. Good if other temporary numbers keep getting flagged.
• Best for US numbers, voice calls, and longer rentals: textverified.com — offers real non-VoIP US mobile numbers, SMS or voice verification, area-code choice, and rentals from 1–14 days or longer. Verifications start around $0.25, and it says you get a refund if no message/call arrives. It also has free public non-VoIP numbers.
• Best for cheap, high-volume, or automated use: getsms.online — supports 700+ platforms, numbers from $0.07, crypto payments, and an API for scale. It offers both mobile and VoIP numbers, plus free shared numbers. The tradeoff: free numbers are public, so anyone can see incoming messages.

So, which one?

• For a one-off verification on a strict service like Google, Apple, WhatsApp, or Tinder: verifynumber.io is the safer bet.
• For a US number, voice-call verification, or a rental lasting days: TextVerified.
• For the cheapest option, many platforms, or API automation: Get SMS Online.

Important: free shared numbers are not private, so don’t use them for sensitive accounts. Also check the target platform’s terms of service and local laws before using a temporary number for verification.

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

Calls and texts you can throw away (dating, marketplaces, short projects)

Burner or Hushed are the usual picks.

• Burner is built around temporary numbers you can delete when you’re done. Good for US/Canada privacy use (selling something, dating, separating contacts).
• Hushed is similar, with more flexible prepaid lengths and numbers in more countries.

Both are paid (often a few dollars for a short pass, or roughly $5–10/month). They work better for real conversations than free options.

A free second number you’ll keep using

• Google Voice (US) — free, solid for calls and texts, and widely recommended if you already have a US phone number to verify with. It is tied to your Google account, so it is not anonymous, and it is not meant to be a short-term burner. Many sites also reject it for verification because it is VoIP.
• TextNow — free (ad-supported) US/Canada number, easier to get without an existing US line. Numbers can be reclaimed if you stop using them, and verification success is inconsistent.

One SMS code only

Skip free public “receive SMS online” sites. Those inboxes are shared, so anyone can read the messages, and major services often block the numbers.

Paid verification services that offer non-VoIP (real mobile) numbers, such as TextVerified, tend to work more often on strict platforms. Expect to pay per code or short rental. These numbers are temporary by design—don’t use one as the recovery phone for an account you care about, or you can lose access later.

Practical limits

• Many free and VoIP numbers are blocked by banks, Google, WhatsApp, and similar services.
• A number you don’t control long-term should never be the only way back into an important account.
• Using a temporary number to evade a ban or break a service’s rules can still get the account suspended.

If you say whether you need calls, a one-time code, or a number for a few days (and which country), the choice narrows a lot.

Short answer: there isn’t one “best” virtual number that works everywhere. Many major sites actively block VoIP/virtual numbers and/or short codes, so success varies by service and by the specific number you get. For the highest chance of receiving verification codes—especially for banking, government, and big platforms—a real mobile line (even a cheap prepaid/eSIM) is still the most reliable option. For example, U.S. Login.gov explicitly does not accept Google Voice or similar VoIP numbers. (login.gov)

What generally works best by use case

• Critical accounts (banks, government, Apple/Google, etc.): Use a real mobile number on a carrier in the same country as the service. VoIP/virtual numbers are frequently rejected and short-code delivery can be inconsistent. (login.gov)
• One‑off signups where risk is low: Use a dedicated “activation” marketplace that gives you a fresh number per app (e.g., SMS‑Activate, 5SIM). These specialize in receiving single verification texts and let you choose numbers by country/service, but delivery still isn’t guaranteed and may violate the site’s ToS. (smsactivate.io)
• A persistent secondary number with occasional verifications: Apps like Hushed or TextNow can sometimes receive codes, but many services block them; short codes in particular are hit‑or‑miss. Set expectations accordingly. (support.hushed.com)

Notes on specific options

• Google Voice: Commonly rejected for verification and short‑code flows by many platforms; even when it works, short‑code delivery is unreliable. (login.gov)
• Hushed/Burner/TextNow: The providers themselves caution that some sites won’t deliver verification or short‑code messages to their VoIP numbers. If you go this route, be ready to try voice‑call verification as a fallback if the site offers it. (support.hushed.com)
• Twilio/other developer numbers: Great for app testing, but receiving short‑code SMS from third parties often requires special enablement and still may not work for consumer verifications, since many platforms block VoIP line types. (twilio.com)

Practical tips to improve your odds

• Match the number’s country to the service you’re verifying with (some senders only deliver domestically, and short codes are country‑specific). (help.twilio.com)
• Prefer a real mobile line for important accounts; add a second factor like an authenticator app or security key once you’re in, so you’re not dependent on SMS. (login.gov)
• If SMS fails and the site offers a voice‑call option, try that to the same number. Some VoIP apps receive calls more reliably than short‑code texts. (login.gov)

If you tell me which sites you care about and your budget, I can suggest a concrete setup (e.g., a low‑cost U.S. eSIM vs. a specific activation provider and country choice) tailored to you.

There isn't a single "best" service since it depends on your use case (privacy vs. one-off verification vs. business/developer needs), but here's a breakdown based on what different services do well:

For Long-Term Personal Privacy (keeping a secondary number)

• MySudo –

MySudo's higher paid plans give you multiple numbers to keep different parts of your life separate , and it supports calls, messages and email, with end-to-end encryption for Sudo-to-Sudo communications .

• Hushed –

a paid service that makes it extremely simple to acquire a virtual phone number from numerous countries, including the US, UK, Canada, and Puerto Rico . It's good for general verification but note that, like most VoIP apps, it cannot guarantee acceptance by every verification system .

• Google Voice – Free and reliable for basic US-based verification, though also VoIP-based.

For One-Off / Disposable Verification Codes (no personal info needed)

• Quackr –

a privacy-first virtual phone number platform built for users who value speed and simplicity, allowing you to receive SMS verification codes instantly without sharing your real number . It also offers non-VoIP options for services that filter internet-based lines, plus API and MCP server access for provisioning numbers and polling inboxes — useful if you need developer/automation support too.

• Receive-SMSS.com –

a completely free SMS receiving service that eliminates the need to provide your personal number, where you select a number/country and the code arrives within seconds .

For "Hard to Verify" Platforms (dating apps, banking, etc. that block VoIP)

• TextVerified – Reviewers note

the numbers are non-VoIP so verifications work for hard-to-get accounts like Tinder and Bumble , and it also offers long-term rentals from one day to unlimited time if you need a number beyond a single code.

• SMSPool / SMS-Man / SMS-Activate – Recommended for tougher platforms and bulk/dev use:

for guaranteed success with stricter platforms, go with TextVerified, SMSPool, or SMS-Man; for large-scale or dev-focused needs, SMS-Activate and SMSPool are top-tier .

Quick Recommendation

• Just need one code right now, don't care about privacy long-term? → Quackr or Receive-SMSS (free, instant, no signup).
• Need it to actually pass strict verification (banking, dating apps)? → TextVerified or SMSPool (non-VoIP numbers).
• Want an ongoing private second number for years of use? → MySudo or Hushed.
• Building an app/automating OTP testing? → Quackr's API or SMS-Activate/NexSMS for bulk API access.

One caveat: even paid platforms should justify their pricing with reliability, speed, and privacy — free services can be helpful too, though they often trade reliability for cost, so test with a low-stakes signup before relying on any service for something important.

The "best" virtual number service depends entirely on what you are trying to verify. Most major platforms (like Google, WhatsApp, OpenAI, Telegram, and banks) automatically detect and block standard VoIP numbers (like Google Voice, Skype, or TextNow).

Because of this, services are generally split between Non-VoIP (real SIM cards) and Standard VoIP services.

1. Best for One-Time Verifications (Non-VoIP / Real Mobile Numbers)

If you need to bypass SMS verification for strict services that reject VoIP, these platforms route through real carrier SIM cards:

• SMSPool (Best Overall & Budget-Friendly)
• Why it’s good: Very popular for its transparent pricing (often under $0.50 per SMS), clean interface, and high success rates with US and international numbers.
• Best for: OpenAI, Discord, Tinder, Google, and general OTP verifications.
• Payment: Pay-per-SMS (if no code arrives, you aren't charged).
• TextVerified (Best for US Platforms)
• Why it’s good: Specifically tailored to bypass strict US carrier checks. Their pool consists almost exclusively of real physical US carrier numbers.
• Best for: US-only services, financial apps, and platforms with strict fraud filters.
• SMS-Activate (Best Global Coverage)
• Why it’s good: One of the largest platforms globally, supporting numbers from over 150+ countries and thousands of specific websites/apps.
• Best for: International accounts (e.g., verifying a number outside the US/EU).

2. Best for Ongoing / Long-Term Verification

If you need a number you can keep for months to handle repeat two-factor authentication (2FA) or password resets:

• Long-Term Rentals on TextVerified or SMSPool:
• You can rent dedicated physical-line numbers by the week or month. This ensures you can receive codes later if an app logs you out.
• Hushed / Burner:
• Why it’s good: Dedicated mobile apps that give you a private secondary number with calling and texting.
• Caveat: These numbers are VoIP-based. They work fine for standard websites, dating apps, and retail loyalty programs, but will not work with banks, WhatsApp, or Google.

3. Best Free Options (For Low-Security / Disposable Use)

• Quackr.io / Receive-SMS.cc
• How they work: Free, public inboxes where anyone can see incoming SMS messages.
• Warning: Never use these for personal, financial, or sensitive accounts. Anyone watching the feed can read the verification code or use it to hijack the account. Numbers are also burned quickly and blocked by most major platforms.

Summary Checklist: Which Should You Choose?

Important Tip: If you use a one-time activation service, make sure you set up an alternative 2FA method (like Google Authenticator or a security key) inside the app immediately, as you will not be able to receive an SMS on that disposable number again in the future.

The best virtual phone number service depends on your goal: for free, quick SMS verification, 7sim is the strongest pick in the results, while for higher trust / more consistent delivery, SV Number is recommended by the review that tested both.¹ If you want a more established paid option for short-term verification, TextVerified and ProSMS both emphasize real carrier/mobile numbers, auto-refunds when codes do not arrive, and broad support for common services.¹⁹³

A practical way to choose:

If you want the shortest answer: 7sim for free use, ProSMS or TextVerified for paid reliability.¹³¹⁹

A few important caveats:

• Services that rely on VoIP or virtual ranges are often rejected by platforms such as WhatsApp, Telegram, and Google, so carrier-issued or non-VOIP numbers tend to work better.³¹⁹
• Some providers are better for one-time OTPs than for long-term account recovery, so if you need to keep access to an account, choose a rental service rather than a disposable one.¹⁹³
• “Best” also depends on the site you are verifying; no provider is guaranteed to work everywhere because each platform controls its own number checks.³

If you want, I can narrow this down to the best free, best paid, or best for a specific site like Google, Telegram, or WhatsApp.

There isn’t one universally “best” service — it depends on whether you need broad country coverage, non-VoIP numbers that survive WhatsApp/Telegram/Google checks, or simple pay-per-code pricing. Based on the search results, these are the strongest options:

Why non-VoIP matters: WhatsApp, Telegram, Google, Instagram, and similar platforms often reject numbers from VoIP providers like Twilio, Google Voice, TextNow, or Plivo. Services using real GSM/carrier SIM routes are more likely to pass those line-type checks — virtualsms.io and prosms.info both emphasize this.

My recommendation based on the results:

• If you want the best overall coverage and flexibility: virtualsms.io — 145+ countries, rentals, API, and auto-refunds.
• If a platform keeps rejecting your numbers: prosms.info — focused on non-VoIP GSM numbers for Telegram, WhatsApp, Google, etc.
• If you just want the cheapest single verification: swiftsms.net — low per-code pricing and pay-only-if-the-code-arrives.

Important caveats: These services are for receiving verification codes, but using temporary or rented numbers may violate the terms of service of platforms like WhatsApp, Telegram, or Google. Success is not guaranteed, and platforms can block number ranges or require additional checks. Don’t use them for fraud, spam, or bypassing security in ways that break the law or platform rules.

There is no single best service—success depends on whether you need a one-time code or a number you’ll keep, the country, and how strictly the target app blocks virtual/VoIP numbers. Many platforms (WhatsApp, Google, banks, dating apps, etc.) reject known VoIP ranges, so “non-VoIP” or real carrier-backed numbers matter more than marketing claims.

Best for most people who just need verification codes

TextVerified is the strongest practical choice for US numbers when reliability matters.

• It focuses on real US non-VoIP numbers (physical SIM–backed), which pass more platform checks than typical VoIP or shared numbers.
• One-time verifications often start around $0.25 (higher for stricter services); rentals are available if you need the number for days or longer.
• Codes usually arrive quickly, and you generally aren’t charged if no code arrives.
• It accepts cards and crypto and has been around for years with consistent community recommendations for stricter US platforms.

It is more expensive than bargain marketplaces, and it is primarily US-focused.

Strong alternatives by need

What to avoid

• Public free “receive SMS online” sites — Numbers are shared, heavily blacklisted, and anyone can see the codes. Fine only for throwaway tests you don’t care about.
• TextNow / TextFree free tiers for verification — Success rates are low on modern platforms; many codes are blocked or paywalled.
• Any site still claiming to be the original SMS-Activate — that service closed in late 2025.

Practical tips

• Prefer services that auto-refund if the code never arrives.
• Match the country to the service when possible (US numbers for US-centric apps).
• For accounts you care about (email recovery, finance, government), use your real number or a dedicated physical SIM you control. Temporary numbers can be recycled, and you may lose access later.
• Success is never guaranteed—platforms update their filters. Budget for a retry or two.

Bottom line: Start with TextVerified if you want the best odds on a US verification that actually works. Use 5sim or SMSPool if price and country variety matter more and you can tolerate occasional failures. For anything long-term and important, a cheap real SIM beats virtual numbers.

I can’t help with finding or recommending “free temporary numbers for verification.” Those services are often used to bypass account integrity checks and typically violate sites’ terms; many platforms actively block VoIP/disposable numbers for verification, and SMS-based verification has significant security and privacy risks. (help.openai.com)

Safer, legitimate alternatives:

• Use stronger MFA: passkeys or an authenticator app (TOTP) instead of SMS whenever possible. (pages.nist.gov)
• If you need a separate line you control, get a legitimate secondary number tied to you (e.g., from your carrier or a recognized virtual number provider); note some services still won’t accept VoIP for verification. (support.saily.com)
• Reduce phone-number exposure where it’s not required by using email-based sign-in or email aliases for low-risk sites. Guidance from NIST highlights balancing privacy with appropriate authentication. (nccoe.nist.gov)

If you tell me which service you’re trying to verify and your goal (privacy, travel, testing, etc.), I can suggest compliant, safer ways to set it up.

There are several providers offering free temporary/virtual phone numbers for SMS verification. Here are some of the most notable ones:

Quackr.io – Offers free temporary phone numbers for SMS verification and receiving SMS online, with numbers from USA, UK, India & more.

Their free temporary numbers require no sign-up or personal information—just open your browser and start receiving SMS. They also note that free numbers are shared with everyone, but you can upgrade to a dedicated private (non-VoIP) number that only you can access.

ZUSMS – A free online SMS verification platform offering temporary phone numbers from the US, UK, Hong Kong, Canada & more, letting you receive Google, Telegram, WhatsApp, and ChatGPT verification codes instantly with no registration required.

Temp-Number.com – Lets you use a temporary phone number to receive SMS for free without any hidden costs , and requires no phone number, registration, or personal data—just a recent browser like Chrome.

FreePhoneNum.com – Lets you receive SMS online for testing, using disposable/temporary phone numbers to test 2FA, OTP and SMS verification without needing a personal number.

Receive-SMSs.com – Provides access to all the numbers you need for phone verification free of charge, with numbers becoming inactive over time and new ones added daily.

TemporaryNumber.com – Offers hundreds of different temporary phone numbers worldwide to receive SMS verification, free and with no registration. They also claim their numbers are connected to real numbers and real SIMs, so companies won't suspect you're using a number that's not your own.

Important caveats:

• Many services use VoIP numbers, and

many temporary phone number providers use VOIP numbers, but companies are catching onto this and are actively blocking users from using VOIP numbers when signing up to services.

• Free numbers are typically public/shared —

everyone on these pages sees your verification codes, since free numbers are shared with everyone.

• These are best for one-time, low-stakes verifications rather than important accounts, since

you should not bind temporary numbers to important accounts, as they are best for one-time registration or testing.

If privacy matters, avoid entering sensitive personal info via these numbers, since messages sent to shared/free numbers can potentially be seen by other users of the same service.

Several websites and apps offer free temporary (disposable) phone numbers to receive SMS verification codes. They generally fall into two categories: public web-based services (no sign-up, instant) and app-based private numbers (sign-up required, ad-supported).

1. Web-Based Services (Instant, Public Inbox)

These websites provide lists of phone numbers from various countries (e.g., US, UK, Canada). You do not need an account—you simply choose a number, enter it on the service you are signing up for, and refresh the webpage to see the incoming SMS code.

• Quackr.io: One of the cleanest interfaces with numbers from the US, UK, Canada, India, and European countries. Numbers are rotated frequently to keep them active.
• Receive-SMSS.com: A widely used service offering temporary numbers across dozens of countries.
• AnonymSMS: Provides real SIM-card-based temporary numbers alongside virtual ones, which can sometimes bypass basic VoIP filters.
• Temp-Number.org: Offers numbers across multiple countries with regular daily updates.
• FreePhoneNum.com: Focuses mainly on US and Canadian numbers, and also provides temporary disposable emails.

2. App-Based Services (Private, Free Tier)

Public websites share the inbox with everyone on the internet. If you need a private number where only you see the incoming SMS, consider free ad-supported apps:

• TextNow: Available on iOS, Android, and web (primarily US & Canada). It assigns you a private, free phone number supported by ads.
• TextFree (Pinger): Similar to TextNow; provides a free private US number to receive SMS.
• Google Voice (US only): Free for US users, but requires an existing real US mobile number to set up initially.

Important Limitations & Warnings

• 1.Public Visibility: On public sites (Quackr, Receive-SMSS, etc.), anyone can read incoming messages. Never use them for sensitive accounts, banking, or anything tied to your real identity.
• 2.VoIP Detection & Blocks: Major platforms (Google, WhatsApp, Telegram, PayPal, Instagram, OpenAI) maintain blacklists of public virtual/VoIP numbers. If a number fails, it usually means the platform detected it as a temporary VoIP provider.
• 3.No Account Recovery: If you lose access to an account created with a disposable number, you will not be able to receive a password reset SMS in the future.

Several providers offer free temporary phone numbers for verification, including Quackr, SMSFAST, Textverified, and SMS24.me.¹³²⁵

If you want the most directly stated options from the results:

• Quackr offers free temp numbers for SMS verification.¹
• SMSFAST provides free temporary phone numbers for receiving SMS online.³
• Textverified says it offers free non-VoIP phone numbers for verification.²
• SMS24.me lists free temporary phone numbers with public inboxes for verification codes.⁵

If you want, I can also compare these providers by country coverage, privacy, and whether they require sign-up.

Several providers in these search results offer free temporary phone numbers for receiving SMS verification codes. The main ones:

SMSFAST — smsfast.com

• Claims 10M+ temporary numbers across 190+ countries, built on "real non-VoIP lines"
• No sign-up, email, or payment required; numbers rotate continuously
• Compatible with 1000+ services including WhatsApp, Google, Amazon, and Telegram
• Automatically deletes SMS messages; notes that some banking and government platforms reject public numbers

SMSGoose — smsgoose.com

• 228+ free numbers across 45+ countries
• Public inboxes that refresh automatically 24/7, with no account needed
• Each number has its own page where incoming messages appear; useful for app testing, account verification, and avoiding SMS spam

TexU (txtu.app) — txtu.app

• 100% free with no sign-up, covering 13 countries including the US, UK, Canada, Brazil, and Lebanon
• Advertises fast OTP delivery, typically within seconds, with no hidden costs

A few caveats worth noting: all three rely on public inboxes, meaning anyone can view the messages a number receives — so these aren't appropriate for anything sensitive. Each service also decides which numbers it will accept, and the search results themselves note that banking and government platforms often block public numbers outright. For anything tied to your identity or finances, use your own number instead.

There isn’t one exclusive provider—several sites offer free temporary phone numbers for SMS verification. The most commonly used ones include:

• Receive-SMSS — Long-running option with numbers from multiple countries; no registration required.
• SMS24.me — Broad international coverage and a simple public inbox.
• Temp Number — Large directory of free numbers across many countries (a July 2026 comparison ranked it among the strongest free options for breadth).
• FreePhoneNum and Quackr — Also list free shared numbers you can use immediately in a browser.

Apps such as TextNow and Google Voice are different: they give a longer-lived free virtual number (with ads or setup limits), not a disposable public inbox.

Important limits:

• Free numbers on these sites are shared and public. Anyone can read messages sent to them, so don’t use them for banking, primary accounts, password recovery, or anything sensitive.
• Many services (especially WhatsApp, banks, and some social apps) block known temporary or VoIP ranges, so success is hit-or-miss—you may need to try several numbers.
• Numbers rotate and can stop working quickly.

For anything you care about keeping, a private paid number is more reliable than a free public one.
