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

To change your username, log into your Roblox account on a computer or phone, go to your account settings, and select the option to change your username. You'll see your current name and a field to enter a new one. Roblox charges 1,000 Robux (the in-game currency) for each change. The new username takes effect when ready once you confirm it, though it may take a few minutes to update across all Roblox games and the website.

The 30-day waiting period starts from the moment you make a change, so you cannot change your username again until that time has passed. If you try to change it sooner, Roblox will show you the exact date when you can make your next change.

Key Takeaways

  • You need 1,000 Robux in your account balance to change your username, which costs real money or must be earned through Roblox games.
  • Each username change has a 30-day cooldown period before you can make another change.
  • New usernames take effect when ready but may take a few minutes to show up in games and on your profile.
  • You cannot reserve a username in advance — you can only claim it when you have the Robux and are ready to change.

How to access your username settings on computer

Open Roblox in a web browser and log in to your account. Click the circular icon in the top right corner of the page (your profile picture or avatar icon). A menu will drop down with several options. Select Settings from this menu.

On the Settings page, click the Account tab on the left side. Scroll down until you see the section labeled Username. Next to your current username, you will see a button that says Change. Click this button to open the username change dialog.

How to access your username settings on mobile

Open the Roblox app and tap the three horizontal lines (the menu icon) in the bottom right corner. Scroll down and tap Settings. Tap Account to expand that section.

Look for the Username field. Tap the Change button next to it. The same dialog will open as on computer, and the process from that point is identical.

Entering and confirming your new username

When the change dialog opens, you will see a text field with your current username highlighted. Delete it and type your new username. Roblox usernames can be 3 to 20 characters long and can include letters, numbers, and underscores. Spaces and special characters like hyphens or periods are not allowed.

As you type, Roblox will check whether the name is available. If the name is taken, you will see a message saying so. If it is available, the message will confirm that. Once you have entered a name that is available and you are happy with it, click the Buy or Confirm button (the exact wording varies slightly by device). Roblox will deduct 1,000 Robux from your account, and your username will change when ready.

What happens if you do not have enough Robux

If your account balance is below 1,000 Robux, the Change button will be grayed out or will show a message that you do not have enough Robux. You will need to purchase Robux through the Roblox website or app before you can proceed. Robux can be bought with real money, or you can earn them through certain games or by selling items if you have a Roblox Premium membership.

The cost is always 1,000 Robux per change, regardless of how many times you have changed your username before or how long your username has been the same.

The 30-day cooldown and what it means

After you change your username, you cannot change it again for 30 days. This cooldown period begins the moment you confirm the change, not at midnight or on any particular schedule. If you change your username on a Tuesday at 3 p.m., you will be able to change it again on the following Tuesday at 3 p.m.

If you try to access the username change dialog before the 30 days are up, Roblox will display the date and time when you will be able to change it next. There is no way to bypass this cooldown, and Roblox does not offer refunds for Robux spent on a username change.

Troubleshooting common problems

If your new username does not appear in games right away, wait a few minutes and refresh your browser or restart the game. The change propagates across Roblox servers, and this usually takes only a few minutes but can occasionally take longer.

If the Change button does not appear in your account settings, check that you are logged in to the correct account and that your account is not restricted. Accounts that have been flagged for violations may have limited access to certain features. If you believe your account has been restricted unfairly, you can contact Roblox support through the Help page on the website.

Frequently Asked Questions

Can I change my username back to what it was before?

Only if no one else has claimed that username in the meantime. Once you change away from a username, it becomes available for anyone else to take. If you want to reclaim an old username, you will need to change to it again and pay 1,000 Robux, but only if it is still unclaimed.

What if the username I want is taken?

You cannot reserve it or put your name on a waiting list. You can only change to a username that is currently available. If the name you want is taken, you will need to choose a different one or wait to see if the person using it changes their username eventually.

Do I lose my games, items, or friends if I change my username?

No. Your account, inventory, game progress, and friend list all stay exactly the same. Only your display name changes. Your friends will see your new username, and you will still have access to everything you owned before the change.

Can I change my username more than once in 30 days if I pay more Robux?

No. The 30-day cooldown is a hard limit that cannot be bypassed by paying extra. You must wait the full 30 days before making another change, regardless of how much Robux you have.

What if I made a typo and want to change my username again right away?

You will have to wait the full 30 days. Roblox does not make exceptions for typos or mistakes. If you realize when ready after changing your username that you made an error, you will need to wait until the cooldown expires to fix it.
