Change your username through account settings

To change your Roblox username, log into your account on the Roblox website, go to Settings, and select the Account tab. You will see a field labeled "Username" with your current name. Click the change button next to it, enter your new username, and confirm the change. The new name takes effect when ready.

You can change your username once every 30 days. If you changed it recently, the system will tell you when you are allowed to change it again. There is a cost to change your username: as of now, the fee is 1,000 Robux (Roblox's in-game currency). You must have enough Robux in your account before you attempt the change.

The username you choose must be between 3 and 20 characters long, contain only letters, numbers, and underscores, and cannot start with a number. Roblox will reject usernames that contain profanity or impersonate official accounts. If your chosen name is already taken, you will see that message and must pick a different one.

Key Takeaways

  • You change your username in Settings under the Account tab on the Roblox website, not in the mobile app.
  • Each username change costs 1,000 Robux and you can only change it once every 30 days.
  • Your new username must be 3 to 20 characters, use only letters, numbers, and underscores, and cannot start with a number.
  • The change takes effect right away, and your old username becomes available for other players to claim after a short delay.

What happens to your old username

When you change your username, your old one does not disappear when ready. Roblox holds it for about 30 days before releasing it to the public. During that time, no one else can use it, but you cannot reclaim it either. After 30 days, another player can take that username if they want it.

Your account history, friends list, and game progress stay with your account no matter what username you choose. Other players who were your friends will still see you on their friends list, though your name will update to the new one. Games you own or have played will still show in your library under your new username.

Where to find the username change option on mobile

If you are using the Roblox mobile app on iPhone or Android, you cannot change your username directly in the app. You must open a web browser, go to the Roblox website, log in, and follow the Settings steps described above. The mobile app does not have the account settings needed to make this change.

Once you change your username on the website, it will show your new name the next time you open the mobile app. You do not need to log out and back in — the app will sync automatically.

Troubleshooting when the change does not work

If you see an error message when trying to change your username, the most common reason is that you do not have enough Robux. Check your Robux balance at the top of the Roblox website. If you have fewer than 1,000 Robux, you will need to purchase more before the change will go through.

If you have enough Robux but still see an error, try logging out completely and logging back in. Clear your browser cache if you are using a computer, or close and reopen the app if you are on mobile. If the problem continues, wait a few minutes and try again — Roblox servers sometimes experience brief delays.

If the username you want is already taken, you will see a message saying so. You cannot reserve a username or put yourself on a waiting list. You must choose a different name or try again later if you think the current owner might abandon it.

Reasons to think before changing your username

Once you change your username, other players may not recognize you right away, especially if you have played with them for a long time. Your old username will be gone after 30 days, so if you change your mind, you cannot get it back. Consider whether your friends and teammates will know who you are under the new name.

Some players use usernames in their social media bios or on Discord servers to help others find them. If you change your Roblox username, you will need to update those links and let people know your new name. The cost of 1,000 Robux also means you should be fairly certain about the change before you spend the currency.

Frequently Asked Questions

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

No. Roblox enforces a 30-day waiting period between username changes. If you try to change it before that time has passed, the system will show you the exact date when you can change it again. You cannot pay extra to bypass this waiting period.

What if someone takes my old username after I change it?

Your old username is held for 30 days before it becomes available to others. Once another player claims it, you cannot get it back. If your old username was important to you, do not change it unless you are certain you want a new one permanently.

Do I lose my Robux if the username change fails?

No. Roblox only charges you the 1,000 Robux if the change goes through successfully. If you see an error message, the transaction does not complete and your Robux stay in your account. You can try again once you have fixed the problem.

Can I change my username if my account is banned or suspended?

No. You cannot access account settings or make any changes while your account is under suspension or ban. You would need to resolve the account status issue first, which usually requires contacting Roblox support through their official website.
