An account can be moved to a different phone number from inside the settings. Nothing is exported, nothing is restored, and nothing is left behind — the account stays exactly as it is and the number attached to it changes.
Which is unusually painless, and has two consequences worth understanding before rather than after.
What you will be able to do
- check_circle Move your account to a new number.
- check_circle Say what happens to your chats and groups.
- check_circle Prepare the two things that can go wrong.
- check_circle Know what your contacts will see.
The account does not move — only the identifier attached to it does.

Because the history lives in the cloud rather than on the handset, there is no migration in the usual sense. Conversations, media, groups, channels you administer, saved messages and settings are attributes of the account, and the account is not being replaced. The number is a label on it.
That is genuinely different from platforms where changing a number means a new identity and an exported archive, and it is why this is a settings screen rather than a procedure. The nervousness people bring to it is borrowed from elsewhere.
What does change is the thing you log in with, and the thing recovery runs through. From the moment it completes, the old number is no longer a way into the account — which is the reassurance and the risk in the same sentence.
What happens to your chats when you change the number?
The conversation history, the groups, the channels you run and every setting stay exactly as they were, because none of them were attached to the number in the first place. The one thing that does not survive a change of device is a secret chat, and that is about the device rather than the number — if you are also moving to a new phone, those do not come with you.
Somebody is later given your old number by the carrier. Can they reach your account?
Once the change is made, the old number has no relationship with your account and a code sent to it opens nothing. This is the strongest reason to do it deliberately when you give a number up: a number you stop paying for is eventually reassigned to a stranger, and an account still attached to it is an account with a recovery path belonging to somebody else.
What do your contacts see?
From their side you are the same person in the same chat, and people who could see your number see the new one. What does not happen automatically is anything outside Telegram — their phone's own contacts still holds the old number, so anybody who calls or texts you conventionally is still using the number you left. If that matters, the announcement has to come from you.
What is the one thing to do before starting?
The process verifies the new number, so it has to be a number reachable at that moment — a SIM in a phone you are holding, not one arriving next week. People get caught out doing this in advance of a move, with a new number that is not active yet. An export is unnecessary since nothing is at risk, and leaving groups would achieve nothing at all.

person_check The part that happens outside the app
Telegram will sort itself out. Everything else will not. The number in your friends' phones, on forms, attached to deliveries and to accounts that send you codes — none of that is touched, and the list is longer than anybody expects.
A short message to the people who need it is worth sending on the day, because the failure mode is slow and invisible: somebody tries the old number in three months, gets a stranger or nothing, and concludes you have vanished. A note in your own chat listing the accounts still pointing at the old number saves the same discovery happening one service at a time.
And if the old number is being given up rather than kept, work through anything that sends verification codes to it before the line closes. That is the genuinely consequential list, and it has nothing to do with messaging.
settings Changing it
- Turn on two-step verification first If it is not already on.
- Have the new SIM in a phone you are holding A code is sent to it.
- Do it while the old number still works Not after it is cancelled.
- Open the settings and change the number Nothing else moves.
- Tell the people who call you Their contacts is not updated.
- Repoint anything that sends you codes Before the old line closes.
This page changes what the account is registered with. The curriculum step is what protects it underneath: the cloud password, the recovery address, and what actually happens when the usual way in stops working.
