What a Telegram username does and why you need one
A Telegram username is a unique handle that lets other people find and message you without knowing your phone number. Instead of sharing your actual number, you give them your username — something like @yourname. Once you set one, anyone on Telegram can search for it and start a conversation with you.
You don't have to create a username to use Telegram. The app works fine with just your phone number. But a username gives you privacy: your phone number stays hidden from people you don't know, and you control who can reach you. If you run a business, a username also makes you easier to find and looks more professional than a phone number.
Usernames are permanent once you set them, but you can change or delete yours anytime. The name you choose is yours alone — no one else on Telegram can use it.
Key Takeaways
- Open Telegram, tap your profile picture, select Settings, then tap Username to create one for the first time.
- Your username must be at least five characters long and can only contain letters, numbers, and underscores.
- Telegram checks when ready whether a username is already taken, so you'll know right away if you need to pick a different one.
- Once you set a username, other people can find you by searching for it, but your phone number stays private.
- You can change your username as often as you want, and your old username becomes available for someone else to use.
Open Settings and find the Username section
Start by opening the Telegram app on your phone. Tap your profile picture in the bottom right corner (on Android) or top left (on iPhone). This opens your profile page.
Look for the word "Settings" and tap it. You'll see several options listed. Scroll down until you find "Username" — it's usually near the top of the Settings menu. Tap on it.
If you haven't created a username yet, the field will be empty or show a message saying you don't have one. This is where you'll type your new username.
Choose a username that follows Telegram's rules
Your username must be at least five characters long. It can contain letters (a–z, A–Z), numbers (0–9), and underscores (_). You cannot use spaces, hyphens, or special characters like @, #, or $.
Telegram doesn't allow usernames that start with a number. Your first character must be a letter. After that, you can mix letters, numbers, and underscores however you want.
Think about what you want people to search for. If your name is Sarah Chen, something like @sarahchen or @sarah_chen works well. If you run a coffee shop called The Daily Brew, @thedailybrew or @daily_brew makes sense. Keep it straightforward — shorter usernames are easier to remember and share.
Type your username and check if it's available
Tap in the username field and type the name you want. As you type, Telegram checks in real time whether that username is already taken. You'll see a green checkmark if it's available or a red X if someone else is using it.
If the username you want is taken, try adding a number or underscore. For example, if @sarahchen is taken, try @sarahchen2 or @sarah_chen_. Keep trying different versions until you find one with a green checkmark.
Once you see the green checkmark, your username is ready to use. Telegram saves it automatically — you don't need to tap a separate Save or Confirm button. The username takes effect when ready.
What happens after you create your username
Once your username is set, people can find you by searching for it in Telegram. They don't need your phone number anymore. When someone searches for @yourname, your profile appears in their results, and they can message you directly.
Your phone number is now hidden from people who find you through your username. They'll see your name, profile picture, and bio, but not your number. This is one of the main reasons to create a username — it keeps your phone number private.
You can still message people and use all of Telegram's features normally. Your username doesn't change how the app works; it just gives people another way to reach you.
How to change or remove your username later
If you want to change your username, go back to Settings, tap Username, and clear the field. Type a new username and wait for the green checkmark. Telegram saves the change right away.
When you change your username, your old one becomes available for someone else to use. People who have your old username saved in their contacts will see it as a link that no longer works, but they can still message you if they have your phone number or your new username.
To remove your username entirely, go to Settings, tap Username, and delete all the text in the field. Leave it blank and tap outside the field. Telegram will remove your username, and people will only be able to find you by phone number again.
Frequently Asked Questions
Can I use my real name as my username?
Yes. Many people use their real name or a version of it. Just remember that anyone searching for that username will find you, so use a name you're comfortable sharing publicly. You can always change it later if you change your mind.
What if the username I want has a space or special character in it?
Telegram only allows letters, numbers, and underscores. If you want a two-word username like "sarah chen", use an underscore instead: @sarah_chen. Hyphens and other symbols won't work.
Can someone else take my username if I delete it?
Yes. Once you remove your username, it becomes available for anyone else to claim. If you think you might want it back, change to a different username instead of deleting it.
Do I need a username to use Telegram?
No. Telegram works with just your phone number. A username is optional and mainly useful if you want privacy or want to be easier to find. You can add one anytime, even after using Telegram for months.
Can I see who searched for my username?
No. Telegram doesn't tell you when someone searches for your username or views your profile. You only know someone found you if they message you or add you to a group.
