You can change your Roblox username once every 30 days through your account settings

To change your Roblox username, log into your account on the Roblox website, go to Settings, select the Account tab, and click the button next to your current username. Type your new username, pay the fee (which varies but is typically around 1,000 Robux for the first change and increases with each subsequent change), and confirm. The change takes effect immediately, though it may take a few minutes to update across all Roblox games and services.

You can only change your username once every 30 days. If you try to change it again before that period ends, you will see a message telling you when you can make your next change. There is no way to speed up this waiting period.

Key Takeaways

  • Username changes cost Robux (Roblox's in-game currency), and the price increases each time you change it within a certain period.
  • You must wait 30 days between username changes, and this timer resets each time you make a change.
  • Your old username becomes available for other players to claim after you change it, so choose carefully if you want to keep it reserved.
  • The change appears immediately in your account settings but may take a few minutes to show up in games and on your profile.

Where to find the username change option

Open the Roblox website and sign into your account. Click the gear icon in the top right corner of the page to open your account menu, then select Settings from the dropdown.

In Settings, click the Account tab on the left side. You will see your current username displayed with a button labeled "Change Username" or a pencil icon next to it. Click that button to begin the change process.

Understanding the cost and Robux requirement

Changing your username requires Robux, which is Roblox's premium currency. The cost depends on how many times you have changed your username recently. Your first username change costs around 1,000 Robux. If you change it again within a certain timeframe, the cost increases — typically to 10,000 Robux or more for subsequent changes.

You must have enough Robux in your account before you attempt the change. If you do not have enough, you will need to purchase more Robux through the Roblox website using real money or a gift card before you can proceed. The purchase happens through your account and is not reversible once confirmed.

What happens to your old username

Once you change your username, your old one becomes available for any other Roblox player to claim. This means someone else could take it. If you think you might want to use that username again in the future, you should know that you cannot reserve it — it enters a general pool immediately.

Your friends will see your new username in their friends list, and your profile will display the new name. However, any games or content you created under your old username will still be associated with your account, so you will not lose access to anything you built or owned.

The 30-day waiting period between changes

After you change your username, you must wait exactly 30 days before you can change it again. This timer starts from the moment you confirm the change, not from when you clicked the button. You cannot bypass this waiting period through any method — there is no premium option or workaround.

If you try to change your username before the 30 days are up, the Settings page will show you the exact date and time when you will be able to make your next change. Plan your username changes with this limitation in mind, especially if you are unsure about a new name.

Troubleshooting common username change problems

If you see an error message saying the username is unavailable, it means another player has already claimed it or it violates Roblox's naming rules. Usernames cannot contain certain words, numbers-only sequences, or patterns that Roblox flags as inappropriate. Try a different name that includes letters and is not similar to a name already in use.

If you do not see the "Change Username" button in your Account settings, you may not have enough Robux, or you may still be within your 30-day waiting period. Check your Robux balance at the top of the page and verify the date you last changed your username. If you recently created your account, Roblox may also restrict username changes for new accounts for a short period.
