Signing up for Telegram with a US number
Telegram needs a phone number for every account. Your first code comes by SMS or call; after that, codes for new logins usually go to the Telegram app on devices where you’re already signed in. Telegram warns that this is no substitute for a number you control, because “whoever has the number, has the account.” So use a rented number only if you’ll keep it as long as the account, and turn on two-step verification.

Why Telegram’s codes usually skip SMS, and why the number still matters
Once you’re logged in somewhere, Telegram sends the code for a new login as a message from “Telegram” in the app on your other devices, not by text. Logging in to Telegram Desktop or Telegram Web works this way too: a Telegram admin has said those apps don’t send SMS at login, and the code goes to the app on your phone.
That makes the number feel unimportant after sign-up. Telegram’s FAQ says the opposite. The phone number is the only way it identifies a user, in-app codes are no replacement for an up-to-date number, and without one you risk losing the account for good. When every device is logged out, a fresh login falls back to the number. If a rental has ended and the number has gone to someone else, that code goes to them.
Two settings narrow the risk. Two-step verification adds a password, after which a login needs both the code and the password. And if you log in often, Telegram may ask you to verify a login email, which it can then use to send login codes.
Which numbers Telegram accepts
Telegram’s FAQ says accounts can only be connected to a mobile number and that landlines aren’t supported. It says nothing about VoIP or virtual numbers either way, and each number can hold one Telegram account.
Ours is a non-VoIP US number. Telegram decides whether to send it a code; if nothing arrives, cancel within 24 hours.
Getting Telegram’s first code on a number from us
Get a number and keep its page open
Rent it for 1 year, with auto-renew on, for the reasons above.
Enter it in Telegram’s sign-up screen
Telegram asks for the number in international format, so enter +1 and then the ten digits. If it offers to call you, or to verify with a flash or missed call, wait for the text instead: a number from us can’t receive calls, and those codes are the call itself.
Paste the code into Telegram
The text appears on the number’s page with the code already picked out. Copy it into Telegram, then set a two-step verification password before you do anything else.
How long to keep the number
For as long as you want the account. Telegram tells users to keep it connected to a number they control, and a rented number is under your control only while the rental runs. 1 year costs $34.99; with auto-renew on, it doesn’t lapse unless you decide.
If you later want the account on a number of your own, Telegram lets you move it and keep everything: go to Settings, tap your phone number above the username, then Change Number. Do it while our number is still active. If the new number already has a Telegram account, Telegram says you have to delete that account first.
Telegram also deletes accounts that don’t come online for 18 months, by default. You can change that period in Settings.
If the Telegram code doesn’t arrive
Telegram’s own advice is short:
- Check the number is in international format, starting +1.
- Look in Telegram on any device that’s already logged in. If you’re signed in anywhere, the code goes to the chat named “Telegram” there, not to SMS.
- For problems signing up or logging in, use the contact form linked from Telegram’s FAQ.
Telegram’s developer documentation adds that where SMS codes cost a lot for a user’s country or provider, Telegram can require a Premium subscription before the login or sign-up goes ahead.
If no text reaches the number’s page, cancel it from 5 minutes to 24 hours after you bought it; when our supplier accepts the cancellation, the money comes back. The general guide to missing codes goes through other causes.
Questions people ask
- Can I use Telegram without a phone number?
- Only with Telegram’s own anonymous numbers, which are blockchain-based and available on the Fragment platform; Telegram says these let you have an account without a SIM card. Every other account needs a phone number.
- Why is Telegram not sending me an SMS code?
- If you’re logged in on another device, Telegram usually sends the code there, as a message in the chat named “Telegram”, instead of by SMS. Telegram Desktop and Web logins work the same way.
- What happens to my Telegram account if I lose the number?
- Telegram says it can’t help unless you still control the number or a logged-in device. From a logged-in device you can change the number in Settings; without one, the number is the way in, for whoever holds it.
- Can two Telegram accounts share one number?
- No. Telegram says each phone number is a separate account, and moving an account to a number that already has one means deleting that other account first.
- I have a new phone number. What do I do on Telegram?
- Telegram’s answer: if the new number is only for a short trip, nothing. If it’s permanent, change the number in Settings while you can still log in; Telegram says you keep everything.
