The steps to change your username on Roblox mobile

Open the Roblox app on your phone or tablet and tap the three horizontal lines (the menu icon) at the bottom right of the screen. Tap your username or profile picture at the top of the menu. On the profile page, look for a pencil or edit icon next to your username — tap it. Type your new username in the text field that appears, then tap the checkmark or confirm button. Roblox will tell you whether the name is available; if it is, confirm the change and you are done.

The entire process takes about one minute. Your new username appears across all your Roblox games and your profile when ready after you confirm. Other players will see the new name the next time they load a game or visit your profile.

Key Takeaways

  • You change your username through your profile menu in the Roblox mobile app, not through settings.
  • Roblox tells you right away whether a username is taken, so you can try another one without waiting.
  • Your new username shows up everywhere — in games, on your profile, and in messages — as soon as you confirm the change.
  • You can change your username as often as you want, though Roblox may limit how frequently you can change it if you do it repeatedly in a short time.
  • The change is permanent once you confirm it; you cannot undo it, but you can change to a different name later.

What happens if your chosen username is already taken

When you type a new username and tap confirm, Roblox checks whether another player is already using it. If the name is taken, the app shows a message saying the username is unavailable. You then type a different name and try again. There is no waiting period — you can try as many names as you want in one sitting until you find one that is free.

If you want a specific name that is taken, you have no way to reserve it or request it from the player who has it. Your only option is to try variations: adding numbers, underscores, or abbreviations. For example, if "Alex" is taken, you might try "Alex123", "Alex_", or "Alexxx".

Where to find the username edit button on different phone screens

The location of the edit button depends on your phone's screen size and the version of the Roblox app you have. On most phones, after you tap your profile picture or username in the menu, you will see your profile page with your username displayed near the top. The edit icon (usually a pencil) appears directly next to or below your username. On tablets or larger screens, the edit button may be to the right of your username instead of below it.

If you do not see an edit button, make sure you are on your own profile page, not someone else's. You can only edit your own username. If you are on the correct page and still cannot find the button, try updating the Roblox app from your phone's app store — older versions sometimes have the button in a slightly different spot.

How long the username change takes to show up everywhere

Your new username appears on your profile and in games almost when ready — usually within seconds of you confirming the change. However, in some cases it may take a few minutes for the name to show up in other players' friend lists or in chat messages if they have the app open. If someone has your profile page loaded in their browser when you change your name, they may need to refresh the page to see the new username.

In rare cases, if you are playing a game when you change your username, the game may still show your old name until you close and reopen it. This does not happen often, but restarting the game guarantees your new name will display correctly.

Restrictions on how often you can change your username

Roblox does not publish an exact limit on how many times you can change your username, but the platform does slow down players who change their name very frequently — for example, multiple times per day over several days. If you change your username and then try to change it again within a short time, Roblox may show a message saying you need to wait before making another change.

The waiting period is temporary and usually lasts a few hours or a day. It exists to prevent spam and abuse. If you change your username once every few weeks or months, you will never hit this limit. Changing your name once or twice a month is normal and will not trigger any restrictions.

What you cannot do with your username

You cannot reserve a username before you create an account, and you cannot hold multiple usernames at once. Each account has exactly one active username. You also cannot see a list of usernames that are available before you try to create one — you have to type a name and let Roblox tell you whether it is taken.

You cannot change your username back to a name you used before if another player has claimed it in the meantime. Once you change away from a username, it becomes available for anyone else to take. If you want to use an old username again and it is now taken, you will have to wait until that player changes their name, which may never happen.

Frequently Asked Questions

Can I change my username on Roblox mobile if I have not verified my email?

Roblox does not require email verification to change your username on mobile. You can change it as long as you are logged into your account. However, if your account is very new (less than a few days old), Roblox may prevent username changes as a security measure.

What if I change my username and then forget what it was?

Your old username is gone and cannot be recovered. However, you can see your current username by opening your profile in the Roblox app — it displays at the top of your profile page. If you need to know what your account name is for any reason, that is where to find it.

Does changing my username affect my Robux or my games?

No. Your Robux balance, game progress, friends list, and all your in-game items stay exactly the same when you change your username. Only the name itself changes. Other players will see your new name, but everything else about your account remains unchanged.

Can I use special characters or spaces in my new username?

Roblox usernames can include letters, numbers, and underscores. You cannot use spaces, periods, hyphens, or other special characters. If you try to use a character that is not allowed, Roblox will show an error message and ask you to try a different name.

What if someone else is using a username that looks like mine?

Usernames on Roblox are case-insensitive, meaning "Alex" and "alex" are treated as the same username. However, players can use similar-looking names like "Aiex" (with an i instead of an l) or "Alex_" (with an underscore). Roblox does not prevent this. If you think someone is impersonating you, you can report them through the in-game report system or by contacting Roblox support.
