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 mobile device, go to your account settings, find the "Change Username" option, and enter your new name. Roblox charges 1,000 Robux for each username change — that's the in-game currency you buy with real money. The change takes effect when ready once you confirm it, and you cannot undo it, so choose carefully.

The 30-day waiting period starts from the moment you complete a username change. If you changed your username yesterday, you cannot change it again for 29 more days. This limit applies whether you paid for the change or not.

Key Takeaways

  • Username changes cost 1,000 Robux and can only be done once every 30 days.
  • You change your username through account settings on the Roblox website or app, not through a game.
  • Your new username takes effect right away and cannot be reversed, so think through your choice before confirming.
  • If you forget your current username, you can still log in with your email address or phone number instead.
  • Changing your username does not affect your game progress, inventory, or friends list.

How to find the username change option on desktop

Open Roblox.com and log in. Click the circular profile icon in the top right corner of the page. A menu will drop down — select "Settings" from that menu. On the left side of the settings page, you will see several tabs. Click "Account." Under the Account tab, look for the line that says "Username" with your current name next to it. Click the "Change" button or link next to your username.

A box will appear asking you to enter your new username. Type the name you want, then click outside the box or press Enter to see if it is available. Roblox will tell you right away if the name is taken or if it breaks the naming rules. If the name is available, you will see a button to confirm the purchase. Click it, and the change is done.

How to change your username on mobile

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." Tap "Account." Look for the username field and tap "Change Username." Enter your new name in the box that appears. Roblox will show you whether the name is available.

If the name is free, tap the button to confirm and pay. The process is the same as on desktop — you will be charged 1,000 Robux, and the change happens right away. Make sure you have enough Robux in your account before you start, or you will need to buy more.

What happens if your desired username is taken

If someone else already has the username you want, Roblox will show you a message saying the name is unavailable. You cannot reserve a name or join a waitlist for it. Your only option is to choose a different name. You can try variations — adding numbers, underscores, or slightly different spellings — to see what is open.

Usernames that break Roblox's naming rules will also be rejected. You cannot use spaces, special characters other than underscores, or names that contain slurs or hateful language. Roblox checks this automatically, so if your choice is rejected, try a different name that follows the rules.

How much Robux you need and where to buy it

A username change costs exactly 1,000 Robux. You can buy Robux through the Roblox website or app using a credit card, debit card, gift card, or other payment methods depending on your region. Prices vary by country, but in the United States, 1,000 Robux typically costs around $10 USD. You can also earn Robux through Roblox Premium membership, which gives you a monthly stipend.

Before you start the username change process, check your Robux balance by clicking your profile icon and looking at the number displayed next to the Robux symbol. If you do not have 1,000 Robux, you will need to buy more before you can complete the change.

Why you cannot change your username back when ready

The 30-day cooldown exists to prevent people from rapidly cycling through usernames to confuse friends or to evade moderation. It also gives Roblox time to track username changes in their system. Even if you regret your choice five minutes after changing it, you have to wait the full 30 days before you can change it again — and you will pay another 1,000 Robux for the second change.

This is why it matters to think through your new username before you confirm. Write it down, say it out loud, imagine seeing it in a game chat for the next month. If you are not sure, wait a day and come back to the decision.

What does not change when you update your username

Your game progress, Robux balance, inventory, and all your items stay exactly the same. Your friends list does not disappear. People who have you added as a friend will still see you in their friends list, though your name will update to the new one. Any games you have created or published will still be yours. Your account history and moderation record do not reset.

The only thing that changes is the name that appears when you play games and chat with other players. Everything tied to your account stays attached to you.

Frequently Asked Questions

Can I change my username if I have been banned or warned?

Yes, a ban or warning does not prevent you from changing your username. However, changing your username will not remove a ban or make a warning disappear. Your account history stays with your account no matter what name you use.

What if I forgot my current username but want to change it?

You can still log in using your email address or phone number instead of your username. Once you are logged in, you can change your username through settings the same way. You do not need to remember your old username to create a new one.

Do I lose my Robux if I change my username?

No. The 1,000 Robux you spend on the username change is deducted from your balance, but all your remaining Robux stays in your account. Your inventory and all purchased items remain yours.

Can someone else take my old username after I change it?

Yes. Once you change your username, your old name becomes available for anyone else to use. If you think you might want it back later, you cannot reserve it or prevent others from taking it.

How do I know if my new username is appropriate?

Roblox will reject any name that contains spaces, most special characters, or content that violates their community standards. If your choice is rejected during the change process, the system will tell you why. You can then pick a different name that follows the rules.
