You can change your username once every 30 days at no cost

Roblox lets you change your username for free once every 30 days. You do not need to pay Robux or use a third-party service. The change takes effect when ready, and your old username becomes available for other players to claim after a short period.

The process takes less than a minute and happens directly in your account settings. If you have changed your username recently, you will see a countdown timer showing when you can change it again.

Key Takeaways

  • You can change your Roblox username once every 30 days without paying anything.
  • The change happens in your account settings under the "Account Info" tab, not through a separate page or tool.
  • Your new username takes effect right away, but your old username stays reserved for a few days before other players can use it.
  • If you see an error message saying the username is taken, try a different name — Roblox usernames are case-sensitive and must be between 3 and 20 characters.
  • You cannot undo a username change, so make sure you want the new name before you confirm.

Step-by-step: changing your username on desktop

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

On the Settings page, click the "Account Info" tab on the left side. You will see your current username displayed with an "Edit" button next to it. Click that button to open the change screen.

Type your new username into the text field. Roblox will tell you right away if the name is already taken or breaks the naming rules. Once you see a green checkmark or confirmation message, click the button to save your new username. The change is final and takes effect when ready.

Changing your username on mobile

Open the Roblox app on your phone or tablet and sign in. Tap the three horizontal lines (menu icon) at the bottom right of the screen, then tap your username at the top of the menu.

Tap "Account Settings," then scroll down and tap "Account Info." You will see your username with an "Edit" option. Tap it, enter your new username, and confirm the change. The process is the same as on desktop, and the change takes effect right away.

Why Roblox shows a 30-day wait between changes

The 30-day rule exists to prevent account takeovers and impersonation. If someone gains temporary access to your account, the delay makes it harder for them to change your username and lock you out permanently. It also stops players from rapidly cycling through usernames to confuse friends or avoid moderation.

The timer resets from the moment you make a change, not from a fixed date each month. If you change your username on March 15, you can change it again on April 14.

What happens to your old username

Your old username does not disappear when ready. Roblox reserves it for a few days to prevent confusion and to give you a brief window to change back if you made a mistake. After that period, other players can claim the username.

Friends who had you added will still see you in their friends list, even though your username changed. Your user ID — a number assigned to your account — never changes, so Roblox uses that to track you, not your username.

Common reasons a username change fails

The most common problem is that the username you want is already taken. Roblox will show you this message when ready when you type it in. Try adding a number, underscore, or different spelling.

Usernames must be between 3 and 20 characters long and can only contain letters, numbers, underscores, and hyphens. Roblox will reject names with spaces, special characters, or words that violate its community standards. If you get an error message, read it carefully — it will tell you what rule the name breaks.

If you see a message saying you have already changed your username recently, you have hit the 30-day limit. You will have to wait until the timer runs out before you can change it again.

Paid username changes and what they are for

Roblox does offer a paid option to change your username more often, but it is not necessary. If you pay 1,000 Robux (the in-game currency), you can change your username when ready without waiting for the 30-day timer. This is useful only if you need to change your name urgently and cannot wait.

For most players, the free option is enough. You get one change every month at no cost, which is plenty for fixing a typo or trying a new name.

Frequently Asked Questions

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

Not directly. Once you change your username, you cannot undo it. However, after a few days your old username becomes available again, and you can claim it if no one else has taken it. If someone else claimed it first, you cannot get it back.

What if I change my username and then regret it?

You will have to wait 30 days before you can change it again. If your old username is still available (usually within a few days), you can claim it back. If someone else took it, you will need to pick a different name.

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

Yes. Your friends list does not break when you change your username. Your friends will see your new username the next time they log in or refresh their friends list. Your user ID stays the same, so Roblox tracks you by that, not by your name.

Can I use special characters or spaces in my new username?

No. Roblox usernames can only contain letters, numbers, underscores, and hyphens. Spaces and special characters like @, #, or ! are not allowed. If you try to use them, Roblox will reject the name and tell you why.

What if the username I want is taken?

Try a variation: add a number at the end, use an underscore between words, or change the spelling slightly. Roblox will tell you when ready if a name is available as you type it. Keep trying different options until you find one that works.
