You cannot change your Telegram User ID, but you can change your username and profile picture

Your Telegram User ID is a permanent number assigned to your account when you create it. Telegram does not allow you to change this number — it is tied to your account and stays the same for the life of your account. However, you can change two things that appear at the top of your profile: your username (the handle people search for) and your profile picture (the icon that shows next to your name in chats). These are the visible parts most people interact with, and changing them is straightforward.

The confusion often comes from mixing up your User ID with your username. Your User ID is invisible to most people and only shows in certain technical contexts. Your username is what you choose — the @handle that appears in your profile and lets people find you by search. If you want to change how you appear to other users, you are changing your username and profile picture, not your User ID.

Key Takeaways

  • Your Telegram User ID is permanent and cannot be changed, but your username and profile picture can be changed at any time.
  • To change your username, open Telegram, tap your profile picture, select Edit Profile, and enter a new username in the Username field.
  • To change your profile picture, tap your profile picture from the profile screen and select a photo from your device or take a new one.
  • Usernames must be at least five characters long, contain only letters, numbers, and underscores, and cannot be changed more than once every 30 days.
  • If you delete your username, your account remains active but people can only find you by your phone number or through direct contact.

How to change your username in Telegram

Open the Telegram app and tap your profile picture in the bottom-left corner (on Android) or top-left corner (on iPhone). This opens your profile screen. Tap the pencil icon or "Edit Profile" button at the top of the screen. You will see several fields including your first name, last name, and username.

In the Username field, delete your current username and type a new one. Usernames must be at least five characters long and can contain only letters (a–z), numbers (0–9), and underscores (_). Telegram will show you a green checkmark if the username is available or a red X if it is already taken or does not meet the requirements. Once you have entered a valid username, tap the checkmark or Save button to confirm the change.

Keep in mind that you can only change your username once every 30 days. If you try to change it again before 30 days have passed, Telegram will tell you when you can make the next change. If you want to remove your username entirely, you can delete the text in the Username field and save — your account will remain active, but people will only be able to find you by your phone number.

How to change your profile picture in Telegram

Open Telegram and tap your profile picture in the bottom-left corner (Android) or top-left corner (iPhone). On your profile screen, tap the large profile picture at the top. A menu will appear with options to take a photo, choose from your gallery, or remove the current picture.

If you select "Take Photo," Telegram will open your camera so you can take a new picture right away. If you select "Choose Photo," you can browse photos already saved on your device. After you select or take a photo, Telegram may let you crop or adjust it before saving. Once you confirm, the new picture appears immediately in your profile and next to your name in all your chats.

You can change your profile picture as many times as you want with no waiting period. If you want to remove your profile picture entirely, tap your profile picture again and select the delete or remove option.

What happens when you change your username

When you change your username, the old username becomes available for someone else to use immediately. Any links to your old username will stop working — if you had shared a link like t.me/oldusername, that link will no longer lead to your profile. People who had you saved in their contacts by username will need to search for your new username to find you again, though they can still message you if they have your phone number saved.

Your User ID does not change when you change your username. Telegram uses your User ID internally to track your account, so all your chats, contacts, and settings stay exactly the same. The username is just a searchable label on top of that permanent ID.

Differences between User ID, username, and phone number

Your User ID is a number Telegram assigns when you create your account. It is permanent, invisible to most users, and cannot be changed. Your username is the @handle you choose — it is searchable, changeable, and optional. Your phone number is what you used to create the account and is how Telegram verifies your identity. People can find you by phone number even if you have no username set.

In group chats and channels, your username appears as a clickable link if you have one set. If you do not have a username, people see only your name. Your User ID is visible only in certain technical contexts, such as when you use Telegram's bot API or when someone forwards a message and checks the message details — most regular users will never see it.

Troubleshooting username changes

If you see a message that says "Username is already taken," the username you chose belongs to someone else. Try a different combination of letters, numbers, and underscores. If you see "Username is invalid," check that it is at least five characters long and contains only letters, numbers, and underscores — no spaces, hyphens, or special characters are allowed.

If you cannot change your username because Telegram says you have to wait, you have already changed it within the last 30 days. You will have to wait until that 30-day period passes. If you are trying to change your profile picture and the photo does not upload, try a smaller file size or a different image format. Telegram accepts JPG, PNG, and other common image formats.
