Yes, you can change your Roblox username, but there are limits on how often

You can change your Roblox username through your account settings on the website or mobile app. The change takes effect when ready, and your old username becomes available for other players to claim after a short period. However, Roblox limits how often you can make changes: your first username change is free, but each change after that costs 1,000 Robux (Roblox's in-game currency, which you buy with real money).

The timing between changes matters. You must wait 30 days after your last username change before you can change it again. If you try to change it sooner, the system will tell you exactly how many days you have left to wait.

Key Takeaways

  • Your first username change is free; every change after that costs 1,000 Robux.
  • You must wait 30 days between username changes, and the system enforces this automatically.
  • You change your username in account settings on the Roblox website or through the mobile app under "Account Info."
  • Your old username becomes available for other players to use after you change it, so you cannot reclaim it later.
  • Username changes are permanent once confirmed — Roblox does not reverse them, so double-check your spelling before you confirm.

How to change your username on the Roblox website

Log into your Roblox account on the website and click your avatar icon in the top right corner. Select "Settings" from the dropdown menu. On the Settings page, click the "Account Info" tab on the left side. You will see a field labeled "Username" with your current name displayed.

Click the "Change Username" button next to your current username. Type your new username into the text box that appears. Roblox will tell you when ready if the name is already taken or if it violates the username rules (no special characters, no spaces, between 3 and 20 characters). Once you enter a name that is available, click "Change Username" to confirm. The change takes effect right away.

How to change your username on the Roblox mobile app

Open the Roblox app and tap the three horizontal lines (menu icon) at the bottom right of the screen. Tap "Settings" at the bottom of the menu. Scroll down and tap "Account Info." You will see your current username listed at the top.

Tap "Change Username" next to your username. Enter your new username in the text field. The app will check whether the name is available and follows Roblox rules. If it does, tap the confirm button to complete the change. Like the website, the change happens when ready.

What happens to your old username after you change it

Your old username does not stay reserved for you. After you change your username, other players can claim your previous name. This usually happens within a few days. If you change your mind and want your old username back, you would have to wait for someone else to claim it first, then hope they eventually change their username so it becomes available again — which is not a reliable way to reclaim it.

Your account history, friends list, and game progress all stay the same when you change your username. Other players will see your new name in games and on your profile, but your account ID (a number behind the scenes) never changes, so Roblox always knows who you are.

The cost and timing rules for multiple changes

Your first username change costs nothing. Every change after that costs 1,000 Robux. The current price of Robux starts at $4.99 USD for 400 Robux, so a username change costs roughly $12 to $13 depending on which Robux package you buy (you will have leftover Robux after the purchase). Prices may vary by country and payment method.

You cannot change your username again until 30 days have passed since your last change. If you try to change it before that window closes, the system will show you a countdown telling you how many days remain. This rule applies whether your last change was free or cost Robux.

Username rules and what Roblox will not let you use

Roblox usernames must be between 3 and 20 characters long and can only contain letters, numbers, and underscores. You cannot use spaces or special characters like hyphens, periods, or symbols. Roblox also blocks usernames that contain profanity, impersonate staff members, or reference hate speech, even if spelled differently.

The system checks your username against a filter before you confirm the change. If your name violates the rules, you will see an error message telling you why it was rejected. You can then type a different name and try again. There is no penalty for trying a name that does not work — you can attempt as many names as you want until you find one that is available and passes the filter.

What to do if you cannot change your username

If the system tells you that you cannot change your username, the most common reason is that you are still within the 30-day waiting period from your last change. Check the message on the screen — it will tell you exactly how many days you must wait. You cannot bypass this rule, even if you buy Robux.

If you see a different error message, your username may have been flagged for violating Roblox rules, or there may be a temporary problem with your account. Try logging out and logging back in. If the problem continues, you can contact Roblox support through the Help page on the website. Go to the "Contact Us" section and describe the issue. Support typically responds within a few days, though response times vary.

Frequently Asked Questions

Can I change my username back to my old one?

Not directly. Once you change your username, the old one becomes available for other players to claim. If someone else takes it, you would have to wait for them to change their username before you could claim it again. There is no way to reserve or lock an old username to your account.

Do my friends still see me after I change my username?

Yes. Your friends list does not change, and your friends will see your new username in games and on your profile. Your account ID stays the same, so Roblox knows it is still you. Your friends do not have to do anything on their end.

Can I change my username more than once every 30 days?

No. Roblox enforces a 30-day waiting period between changes. You cannot pay extra Robux to skip this wait. The timer starts from the moment you confirm your last username change, not from when you started the process.

What if my username was created by my parents and I want to change it?

You can change it yourself if you have access to the account. Log in, go to Account Info, and follow the steps above. If your parents set a PIN on the account to prevent changes, you will need to ask them to remove it first. They can do this in the account settings under "Security."

Does changing my username affect my Robux or game items?

No. Your Robux balance, game items, and all progress stay exactly the same. Only your display name changes. Your account owns everything the same way it did before.
