The steps to change your username on Roblox

You can change your Roblox username through your account settings on the Roblox website. The process takes about two minutes and requires you to be logged in. Roblox lets you change your username once every 30 days, and each change costs 1,000 Robux (the in-game currency) or 12,500 Robux if you do not have a membership.

To change your username, go to the Roblox website, log into your account, and click the gear icon in the top right corner to open settings. Select "Account" from the menu on the left side. Under the "Username" section, you will see your current name with a "Change" button next to it. Click that button, type your new username, and confirm the purchase.

Your new username takes effect when ready after you complete the purchase. Other players will see your new name in games, on your profile, and in chat. Any games you own, items you have collected, and friends you have added stay with your account — changing your username does not affect any of that.

Key Takeaways

  • You can change your username once every 30 days through your account settings on the Roblox website.
  • The change costs 1,000 Robux if you have a membership, or 12,500 Robux if you do not.
  • Your new username appears everywhere when ready — in games, on your profile, and in messages.
  • Changing your username does not affect your games, items, friends list, or account history.
  • You must be logged in to your account and have enough Robux in your balance before you start the change.

What happens if you do not have enough Robux

If your account does not have enough Robux to cover the username change, you will see the cost when you click the "Change" button, and the system will not let you proceed until you add more. You can buy Robux directly through the Roblox website by clicking "Buy Robux" in the top right corner of any page.

Roblox sells Robux in packages starting at 400 Robux for about $5 USD, with larger packages available at higher prices. The exact dollar amount varies by country and payment method. If you have a membership, you also receive a monthly stipend of Robux that you can use toward a username change.

The 30-day waiting period between changes

After you change your username, you must wait 30 days before you can change it again. This timer starts the moment your new username takes effect, not when you click the button. If you try to change your username before the 30 days are up, the "Change" button will show you how many days remain.

There is no way to skip this waiting period or change it. If you made a mistake with your new username, you will need to wait the full 30 days before you can try again. For this reason, it is worth taking a moment to make sure your new username is spelled correctly and is something you will be happy with for at least a month.

Username rules and what Roblox will not allow

Roblox has rules about what usernames can contain. Your username must be between 3 and 20 characters long and can only use letters, numbers, and underscores. Spaces and special characters like hyphens, periods, or symbols are not allowed.

Roblox will reject usernames that contain profanity, hateful language, or references to illegal activity. The system also blocks usernames that are too similar to existing famous accounts or that impersonate real people. If you try to use a username that breaks these rules, you will see an error message telling you the name is not allowed, and you can try a different one without losing your Robux.

Changing your username on mobile versus desktop

You can only change your username through the Roblox website on a computer or tablet — the mobile app does not have this feature. If you are on a phone, open the Roblox website in your mobile browser, log in, and follow the same steps: tap the gear icon, go to Account settings, and click Change next to your username.

The process is identical whether you use a computer or mobile browser. You still need the same amount of Robux, and the 30-day timer works the same way. The only difference is that the layout on a small screen may look slightly different, but all the buttons and options are in the same places.

What to do if your username change does not go through

If you clicked "Change" and paid the Robux but your username did not update, wait a few minutes and refresh the page. Sometimes the change takes a moment to process. If your username is still the same after 10 minutes, check your Robux balance to see if you were charged — if you were, the change should appear within an hour.

If your Robux were taken but your username never changed, or if you see an error message, contact Roblox support through the help page on the website. You will need to describe what happened and provide the date and time you tried to change it. Roblox support can check your account history and refund your Robux if there was a system error.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but you have to wait 30 days and pay the Robux cost again. If you changed your username and want to go back, you can do that on your next change date. Keep in mind that if someone else took your old username in the meantime, you will not be able to use it.

Do my friends see my old username or my new one?

Your friends see your new username everywhere — in their friends list, in games, and in chat. Your old username disappears completely. They will not see a notification that you changed it unless you tell them.

What if someone else is using the username I want?

If the username you want is already taken, Roblox will tell you it is not available when you try to use it. You will have to choose a different name. There is no way to claim a username that someone else is using, even if that account is inactive.

Can I change my username if my account is banned?

No. If your account is banned, you cannot log in or access any account settings, including the username change feature. You would need to appeal the ban first through Roblox support.

Does changing my username affect my game progress or items?

No. Your games, items, Robux balance, friends list, and all account data stay exactly the same. Only your display name changes. Other players will see your new name, but everything else about your account remains unchanged.
