You can change your Bumble username in the app settings, but only once every two weeks

Open Bumble and tap the profile icon in the bottom right corner. Select Settings, then tap Username. Type your new username — it must be between 3 and 20 characters, contain only letters, numbers, and underscores, and cannot start with a number. Tap Save or Confirm depending on your device. The change takes effect when ready, but you cannot change it again for 14 days.

If the username you want is already taken, Bumble will tell you and ask you to try another. You do not need to pay anything to change your username, and changing it does not affect your matches, messages, or account history.

Key Takeaways

  • Go to your profile, select Settings, then Username to make the change in the app.
  • Your new username must be 3 to 20 characters and can only contain letters, numbers, and underscores.
  • You can change your username once every 14 days, so plan ahead if you want to switch again soon.
  • Changing your username does not delete your account, messages, or matches — only the name other users see changes.
  • If your desired username is taken, try adding a number or underscore to make it unique.

What characters and lengths are allowed

Bumble usernames must be between 3 and 20 characters long. You can use uppercase and lowercase letters (A–Z, a–z), numbers (0–9), and underscores (_). You cannot use spaces, hyphens, periods, or special characters like @, #, or $. Your username also cannot start with a number — it must begin with a letter or underscore.

If you try to save a username that breaks these rules, Bumble will show an error message and ask you to fix it. The app will tell you exactly what is wrong, so you can adjust before trying again.

The 14-day waiting period between changes

After you change your username, you must wait 14 days before changing it again. This limit applies whether you change it once or multiple times. If you try to change your username before the 14 days are up, Bumble will show you a countdown telling you how many days remain.

This waiting period exists to prevent spam and keep usernames stable so your matches can find you. If you realize you made a typo or chose a username you dislike, you will have to wait the full two weeks before you can fix it. Plan your username carefully the first time.

What happens to your messages and matches when you change your username

Changing your username does not affect your conversations, matches, or account in any way. People you have already matched with will still see your messages and your profile — the username change just updates what new users see when they search or browse. Your match history, unread messages, and all your account data stay exactly the same.

The person you are talking to will see your new username the next time they open the conversation or refresh the app. They will not receive a notification that you changed it.

Troubleshooting a username that will not save

If Bumble will not let you save your new username, check that it follows the rules: 3 to 20 characters, letters and numbers only (plus underscores), and starting with a letter or underscore. If your username meets those rules but still will not save, the username may already be taken. Try adding a number or underscore to the end and try again.

If you see an error message that does not mention the username rules, close the app completely and reopen it. Sometimes a temporary glitch prevents the change from going through. If the problem continues after restarting, try changing your username on a different device (like a computer or tablet) if you have access to one, or contact Bumble support through the app's Help section.

Changing your username versus changing your display name

Bumble has two separate name fields: your username (the handle other users see) and your display name (the first name or nickname shown on your profile). You can change your display name as often as you want with no waiting period — it is in the same Settings menu, usually labeled Name or Display Name. Your username has the 14-day limit.

Most people use their first name or a nickname as their display name and a more unique handle as their username. If you only want to change how your name appears on your profile, edit the display name instead — that change is when ready and has no restrictions.

Frequently Asked Questions

Can I change my username back to what it was before?

Yes, but you still have to wait 14 days between changes. If you changed your username and want to switch back, you will have to wait two weeks, then change it again. There is no special "undo" option.

What if someone else takes the username I want after I change mine?

Usernames are first-come, first-served. If someone else claims the username you want while you are waiting out your 14-day period, you will not be able to use it. Choose a backup username in case this happens, or wait and see if it becomes available later.

Does changing my username affect my Bumble BFF or Bumble Bizz profile?

If you use multiple Bumble modes (dating, BFF, or Bizz), they all share the same username. Changing it in one mode changes it in all of them. You cannot have different usernames for different modes on the same account.

Will my matches be notified that I changed my username?

No, your matches will not receive a notification. They will straightforward see your new username the next time they open the app or refresh your profile. There is no announcement or alert about the change.
