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

Roblox lets you change your username once per month without paying. You do this through your account settings on the Roblox website or app. The change takes effect when ready, and your old username becomes available for other players to claim after a short waiting period.

The process is straightforward: log in, go to your account settings, find the username field, type your new name, and confirm. Roblox will check whether the name is already taken or violates their naming rules. If it passes, you're done. If you try to change it again before 30 days have passed, the system will tell you when you can change it next.

Key Takeaways

  • You can change your Roblox username once every 30 days without paying anything.
  • Username changes happen through account settings on the website or mobile app, not in the game itself.
  • Your new username must not already be taken and must follow Roblox's naming rules, which ban profanity, impersonation, and certain symbols.
  • After you change your username, your old name becomes available for others to use after a waiting period.
  • If you want to change your username more than once per month, you must pay Robux, Roblox's premium currency.

Step-by-step: changing your username on the website

Open a web browser and go to roblox.com. Log in with your email and password. Once you're on your home page, look for the gear icon or menu button in the top right corner and select "Settings" or "Account Settings."

In the settings menu, find the "Account Info" tab. You'll see a field labeled "Username" with your current name. Click on that field, delete your old username, and type your new one. Roblox will show you whether the name is available as you type. If a red message appears saying the name is taken or breaks the rules, you'll need to pick a different one.

Once you've entered a name that works, click the "Save" or "Confirm" button. Roblox will ask you to re-enter your password to confirm the change. Type it in and submit. Your new username is now active.

Changing your username on the Roblox mobile app

Open the Roblox app on your phone or tablet and log in. Tap the three horizontal lines (the menu icon) at the bottom right of the screen. Scroll down and tap "Settings."

In Settings, tap "Account Info." You'll see your current username displayed. Tap on it to edit. Type your new username and check whether it's available. Once you've chosen a name that works, tap "Save" or "Confirm," then re-enter your password when prompted.

Rules for choosing a new username

Roblox usernames can be 3 to 20 characters long and can include letters, numbers, and underscores. You cannot use spaces, periods, hyphens, or most other symbols. The name cannot contain profanity, slurs, or references to real people's names in a way that looks like impersonation.

Names that are already taken will be rejected when ready. If you see a message that your name "violates community standards," it means Roblox's filter flagged it as inappropriate. Try removing numbers, changing the spelling slightly, or picking a completely different name. There's no appeal process for rejected usernames — you straightforward choose another one.

What happens to your old username

When you change your username, your old one doesn't disappear right away. Roblox holds it for a waiting period (usually a few days to a week) before making it available to other players. During that time, no one else can claim it, and your account history remains tied to your new name.

Your friends' lists, game progress, inventory, and Robux balance all stay with your account. The only thing that changes is the name other players see when they interact with you. If someone bookmarked your profile or sent you a message using your old username, those links and messages will still work because they're tied to your account ID, not your username.

Changing your username more than once per month costs Robux

If you want to change your username again before 30 days have passed, you'll need to spend Robux. The cost is typically 1,000 Robux for an extra change. Robux is Roblox's premium currency that you buy with real money or earn through game development.

To make a paid username change, go to your account settings and attempt to change your username. If you're within the 30-day window, the system will show you the Robux cost and ask whether you want to proceed. If you have enough Robux in your account, you can complete the purchase when ready. If not, you'll need to buy more Robux first through the Roblox website or app.

Troubleshooting common problems

If you see a message that says "Username already taken," that name belongs to another player. Try adding numbers to the end, using an underscore, or picking a different name entirely. If the message says your name violates community standards, Roblox's filter rejected it as inappropriate. Rephrase it or choose something different.

If you're locked out of changing your username because you changed it recently, you'll see a message telling you exactly when you can change it again. You cannot bypass this 30-day timer without paying Robux. If your account was hacked or compromised, contact Roblox support through their help center — they may be able to reset the timer in certain situations.

If your change doesn't seem to take effect, try logging out completely and logging back in. Sometimes the new username takes a few minutes to show up across all Roblox services. If it still doesn't appear after 10 minutes, refresh the page or restart the app.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but only after the waiting period ends and someone else hasn't claimed it. If your old username is still available, you can change to it just like any other name. If someone else has taken it, you'll need to wait until they change their username or contact Roblox support if you believe your account was compromised.

Do my friends see my username change right away?

Yes. Your friends' lists update when ready to show your new username. Any messages or notifications they receive will use your new name. Your account ID stays the same, so they can still find you through their friends list even if they don't remember your new name.

What if I change my username and then regret it?

You can change it again, but you'll have to wait 30 days or pay 1,000 Robux to do it sooner. There's no undo button, so make sure you're happy with your new name before confirming the change.

Can I use special characters or emojis in my username?

No. Roblox only allows letters, numbers, and underscores. Spaces, periods, hyphens, and emoji are not permitted. If you try to use them, the system will reject your username and ask you to pick a different one.

Does changing my username affect my game progress or items?

No. Your inventory, Robux balance, game progress, and all your items stay with your account. Only the name changes. Everything else remains exactly as it was.
