People say OTP number for a phone number that only has to receive a one-time password. In the SMS For U app you pick the service and a country, enter the number at the service and read the OTP on your screen. The number is reserved for you and goes back into circulation afterwards.
How to get your OTP
- Install SMS For U from the App Store on iPhone or from Google Play on Android.
- Search for the service that asks for your number.
- Pick a country the app lists for that service right now, and confirm.
- Enter the number at the service and ask for the code.
- The OTP appears in the app on its own. Copy it across.
What an OTP number does, and what it does not
It receives the text message with the one-time password. It does not make calls, it cannot reply, and you do not keep it for later logins.
Private, not a public list
Free number lists show every message to everyone who opens the page, so your code can be read and used by someone else. Our number is reserved for you alone while you wait for the code.
When a service refuses the number
Some services refuse whole number ranges before they send anything. Then another try with the same country usually fails too. Cancel, and pick another country.
Where it does not fit
Banks, wallets and payment apps: our terms rule them out in every country. Accounts you must keep for years belong on your own number, because the service may ask for the same number again.
Common questions
What is an OTP number?
A phone number used only to receive a one-time password. You enter it at the service, the OTP arrives, and the number has done its job.
Is a free OTP number safe?
Public numbers show your code to anyone on the page, and most big services refuse them. For anything that matters, use a number only you can read.
What if no OTP arrives?
You do not pay for a number that brought no code. Cancel it in the app and try another country.
Can I get an OTP number for WhatsApp or Telegram?
Yes, pick the service in the app. WhatsApp checks numbers strictly and Telegram may show the code in an app where you are already signed in.
