Where to Find the Username Change Option

Open Roblox in your web browser and sign into your account. Once you are logged in, click the circular icon with your avatar in the top right corner of the page. A dropdown menu will appear with several options.

From that menu, select Settings. This takes you to your account settings page, where all your profile information lives. You will see tabs across the top of the page — click the Account tab to find username controls.

Key Takeaways

  • Your username change option is in Settings under the Account tab, accessible from the avatar menu in the top right corner.
  • Roblox charges 1,000 Robux for a username change, and you must wait 30 days between changes.
  • Your new username must be between 3 and 20 characters, contain only letters, numbers, and underscores, and cannot already be taken.
  • Once you change your username, your old name becomes available for other players to claim after a short period.
  • You can change your username on mobile or computer, but the steps are the same regardless of device.

The Username Field and Change Button

In the Account tab, scroll down until you see the Username field. This shows your current username. Next to it, you will see a button labeled Change or Change Username depending on your account age and region.

Click that button. A dialog box will open asking you to confirm that you want to proceed. This is where Roblox tells you the cost: 1,000 Robux. If you do not have enough Robux in your account, you will need to purchase more before continuing.

Entering Your New Username

After you confirm the cost, a text field appears where you type your new username. Roblox enforces specific rules: your username must be between 3 and 20 characters long, can only contain letters (A–Z, a–z), numbers (0–9), and underscores (_), and cannot be a username that is already taken by another player.

Type your desired username into the field. As you type, Roblox checks in real time whether that name is available. If the name is taken, you will see a red message saying so. If it is available, you will see a green checkmark or confirmation message.

Do not use spaces or special characters like hyphens, periods, or symbols — Roblox will reject them. If you want to separate words, use an underscore instead. For example, cool_player_123 works, but cool-player-123 does not.

Confirming the Purchase and Waiting for the Change

Once you have entered a valid, available username, click the button to confirm the change. Roblox will deduct 1,000 Robux from your account when ready. Your username changes right away — you do not have to wait for it to take effect.

After you change your username, Roblox prevents you from changing it again for 30 days. If you try to change it before that period ends, the button will be disabled and show a countdown timer telling you how many days remain.

What Happens to Your Old Username

When you change your username, your old one does not disappear forever. Roblox releases it back into the pool of available names after a waiting period, usually a few weeks. Other players can then claim it if they want to.

Your account history, friends list, games, and inventory all stay with you — they are tied to your account ID, not your username. Changing your name does not affect any of that. People who had you added as a friend will still see you on their friends list, though your name will now show as your new username.

Troubleshooting Common Problems

If the Change button is grayed out or missing, check whether you have enough Robux. You need exactly 1,000 Robux available in your account. If you have spent Robux recently, you may need to purchase more. Visit the Robux shop from the menu to buy more if needed.

If you see an error message saying your username is unavailable even though you just checked it, try refreshing the page and entering the name again. Sometimes the availability check lags slightly. If the name is still marked as taken, another player claimed it between when you checked and when you tried to confirm.

If you are under 13 years old, your account may have restrictions that prevent username changes. Contact Roblox support through the Help page if you believe your account should allow changes but the button is not appearing.

Frequently Asked Questions

Can I change my username for free?

No. Roblox charges 1,000 Robux for every username change. This is a one-time fee per change, not a subscription. If you change your username again later, you will pay 1,000 Robux again.

How long do I have to wait before changing my username again?

You must wait 30 days between username changes. After you change your username, the Change button becomes unavailable and shows a countdown timer. Once the 30 days pass, you can change it again if you have another 1,000 Robux.

What if the username I want is already taken?

You cannot use a username that another player has claimed. Try a variation instead — add numbers, underscores, or extra letters. For example, if shadowplayer is taken, try shadowplayer_1 or shadowplayer123. Check availability as you type to find an open name.

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

Yes. Your friends list and all your account data stay the same. Your friends will see your new username on their friends list and in games. Your account ID never changes — only the display name does.

Can I change my username on mobile instead of computer?

Yes. The steps are identical on mobile and computer. Open Roblox in your mobile browser, go to Settings, click the Account tab, and use the Change button next to your username. You can also use the Roblox mobile app if you prefer.
