Get a temporary Arvesi virtual number for SMS verification
A temporary number is a virtual phone number for receiving OTPs without exposing your real SIM card number.
Single-use · held for 20 minutes · from $0.01 · refunded in full if no code arrives
What “temporary” actually means here
The number is yours from the moment you order it until the arvesi code lands, or twenty minutes pass — whichever comes first. Then it is released.
It is not a shared inbox. For that window the number routes to your screen and nobody else's, which is the whole difference from a free public number.
No code, no charge — the refund is automatic and goes back to your balance. You are never billed for a number that stayed silent.
It cannot receive a second code, and you cannot get it back later. That is what keeps it at $0.01 instead of a monthly line rental.
Because the number is recycled after you, don't attach one to an account you intend to keep. If arvesi will ever text you again — a login, a password reset, a delivery code — you want a rented number that stays yours, not a temporary one.
A temporary number is a virtual phone number you can use to receive SMS messages, specifically one-time passcodes (OTPs), without exposing your real SIM card number. It's a disposable layer between your personal identity and the apps you're signing up for. If you value privacy, test apps, or build automation workflows, this guide explains how temporary numbers work, what they cost, and when to use them.

What Is a Temporary Number? Meaning & Beginner Explanation
A temporary number is a virtual phone number that receives SMS messages, especially OTP codes, without connecting to your personal SIM card. It's a short-lived, disposable layer between your identity and the services you're verifying with. You use it once or rent it briefly, then move on, keeping your real number private and free of spam.
Unlike a second SIM or a burner phone, a temporary number is rented digitally and ready in seconds. "Temporary" doesn't mean low quality; it means short-lived by design. Numbers work with real, active lines (not VoIP-only) that can receive OTPs from apps like WhatsApp, Telegram, and Google.
A reliable temporary number service offers two options: one-time use for a single code, or longer rentals (24 hours to 30 days) for ongoing verification. The core benefit? Your personal number stays off marketing lists, data brokers' databases, and spam callers' radar.
How Does a Temporary Number Work?
The process takes less than a minute. Here's how it works:
Step 1: Pick a country and select the app you need (WhatsApp, Telegram, Google, or hundreds of others).
Step 2: Pay per use (from $0.01) or rent a number for a fixed period.
Step 3: Enter the provided number in the app's verification screen.
Step 4: The OTP code lands in your dashboard within seconds.
Step 5: Copy the code, paste it into the app, and you're verified.
The service handles all the SIM infrastructure, so you don't need any hardware. Whether you're doing WhatsApp verification or another app, the experience is the same: instant number, instant code.
If no code arrives within the service's stated window, you're eligible for an automatic refund. That safety net makes paid services far more reliable than free alternatives. You can also receive SMS online for multiple apps from one dashboard.

Temporary Number API for Developers - Integration Guide
For developers, the temporary number API is where things get powerful. It lets you request a number and poll for OTP status programmatically; no dashboard clicks needed. A few HTTP requests handle the entire lifecycle: request number, check status, fetch the code.
Here's a practical example of the API flow:
- POST /numbers/request → Get your temporary number
- GET /numbers/{id}/status → Poll for SMS arrival
- GET /numbers/{id}/otp → Retrieve the received code
Common use cases for the API:
- Automated testing of your app's SMS onboarding flow
- CI/CD pipelines that verify OTP functionality on every deploy
- Internal tooling that needs on-demand numbers at scale
- Multi-account verification for legitimate business use
Most developers go from zero to live in under an hour using documented endpoints. The API is RESTful and returns JSON, so it integrates cleanly with any modern stack.
Temporary Number API for OTP & SMS Automation
Pair the API with automation to unlock hands-free verification. The API returns the OTP directly to your script, so your automation completes the entire verification step without human intervention. No more babysitting the process or manually copying codes.
What this enables in practice:
- CI/CD testing: Automatically verify your app's SMS OTP flow every time you deploy a new build.
- User acceptance testing (UAT): Simulate real user sign-ups with fresh, valid numbers to catch UX bugs early.
- Bulk workflow automation: Verify multiple accounts for legitimate testing or internal use without manual steps.
- Cost reduction: The API replaces physical SIM cards entirely, lowering your testing infrastructure spend.
The OTP arrives in real time, so your automation never stalls waiting for a code. This makes the temporary number API a genuine upgrade for QA teams and developers who previously had to manage physical devices to test SMS flows.
Temporary Number Cost - Free vs. Paid & Refund Policy
There's no reliable, completely free temporary number service. Free options are usually shared, slow, and often fail on major apps. Paid pay-per-use services, by contrast, are genuinely cheap and far more dependable.
Option Cost Reliability Refund
Free numbers $0 Low; often blocked by major apps None
Pay-per-use From $0.01 High; dedicated line per request Automatic if no code
Rental Daily to monthly High; number reserved for your use Per service policy
The key difference is the refund policy. A good paid service will refund you automatically if no code is delivered; you never pay for a failed attempt. Our pay-per-use pricing starts at $0.01, with transparent costs per country and app shown up front.
For long-term needs like keeping a Telegram account active, you can rent a number for a day or month. Renting is cheaper than repeated single-use purchases when you need the number beyond one verification. And free numbers for quick tests exist, but don't rely on them for critical verifications.

How to Choose the Right Temporary Number Service
Look for three things: transparent coverage, honest pricing, and a real refund policy. A service that openly lists which countries and apps it supports and doesn't overpromise success rates is one you can trust.
Your checklist:
- Coverage: Confirm the service supports your specific app and country before paying.
- Pricing transparency: Look for exact per-number costs shown up front, with no hidden fees.
- Refund terms: Automatic refunds are the strongest signal a service trusts its own product.
- API access: If you're a developer, verify the API is documented and accessible.
- Security stance: Ensure the service explicitly prohibits fraud and spam.
Choose based on whether you need a quick one-off code or a longer rental window. And remember: don't use temporary numbers for banking, government portals, or accounts you might need to recover years later. Those require your real identity.

Temporary, free, or rented?
Three different products that all put a number between you and arvesi. Most people verifying once want the first.
Temporary number
A private number, yours for one arvesi code. It expires after that, so nobody else ever receives your codes. Cheapest way to verify once.
Free public number
A shared inbox anyone can read. Fine for testing your own app — never for a real arvesi account, because strangers see the code too and the number is usually already registered.
Rented number
The same number kept for days or weeks, receiving unlimited SMS. Use it when you need to log back in to arvesi later, or receive more than one code.
Questions about temporary arvesi numbers
Is it legal and safe to use a temporary number for OTP verification?
Yes, as long as you're using it for legitimate purposes like testing your own apps, protecting your privacy, or signing up for services you intend to use. It's illegal to use temporary numbers for fraud, spam, or to violate an app's terms of service.
Why does my temporary number sometimes fail to receive a code?
The most common reasons are high demand for a specific country/app combination, the app blocking virtual numbers, or the number being flagged for previous misuse. A reliable service will show coverage data up front and refund you if the code doesn't arrive.
What's the difference between a one-time number and a rental number?
A one-time number is for a single verification; you pay once and use it briefly. A rental number is yours for a set period (e.g., 24 hours to a month) and is ideal for keeping an account active or receiving multiple messages over time.
What should I NOT use a temporary number for?
Avoid using temporary numbers for anything that requires long-term proof of identity, like banking, government services, or critical accounts you might need to recover later. Also, don't use them for activities that violate an app's terms of service.
How do I troubleshoot a code that hasn't arrived?
First, double-check that the number you entered matches the one on your dashboard. Wait a full 60–90 seconds for delivery. If it still doesn't arrive, request a new code in the app. If it fails again, the number may not be supported for that service. Check. Check the coverage page or request a refund.
