Quick answer
What is a virtual number for SMS verification?
A virtual number is a real mobile number you can use online, without a SIM card, to receive one-time passwords (OTPs) from apps like WhatsApp, Telegram, Google or TikTok. On OTPWave you buy one for a single verification from about ₦1,000, read the code on screen, and get refunded automatically if no code arrives.

How it works
- You choose the app and country you need.
- A number is assigned to you instantly.
- You enter it in the app and request an SMS code.
- The code is forwarded to your dashboard within seconds.
One-time numbers vs rentals
A one-time (temporary) number receives the code for a single verification and expires after about 20 minutes. A rental keeps the same number for days so it can receive several messages. On OTPWave rentals come in the lengths each country offers, usually 1, 3 or 7 days, and can be extended on the same number.
Good reasons to use one
- Keep your personal number private when signing up online
- Separate business and personal accounts
- Verify an app that doesn't support your country's numbers
- Test sign-up flows as a developer
What a virtual number can't do
- Receive voice calls (SMS only)
- Guarantee that every app will accept it, since some apps block virtual numbers
- Be used to impersonate someone, evade a ban or break an app's rules (not allowed on OTPWave)
