You can change your 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 by account age), and confirm the change. The new name takes effect when ready, though it may take a few minutes to show up everywhere in the game.

Roblox limits username changes to once per 30 days to prevent abuse. If you changed your username recently, you will see a countdown timer showing when you can change it again. There is no way to speed this up or request an exception.

Key Takeaways

  • Username changes cost Robux (Roblox's in-game currency), with the price depending on how old your account is and how many times you have changed it before.
  • You must wait 30 days between username changes, and this waiting period cannot be skipped.
  • Your old username becomes available for other players to claim after you change it, so choose carefully if you plan to switch back later.
  • Changing your username does not affect your game progress, items, or friends list — everything stays with your account.

Step-by-step: changing your username on desktop

Open a web browser and go to the Roblox website. Log in with your email and password. Click the gear icon in the top right corner and select Settings.

In the Settings menu, click the Account tab on the left side. Find the section labeled "Username" and click the button next to it that says "Change." A text box will appear where you can type your new username. Roblox will tell you when ready if the name is already taken or breaks the naming rules (no special characters, numbers only at the end, no spaces).

Once you enter a valid name, Roblox shows you the cost in Robux. Click Confirm, and the change is complete. Your new username appears on your profile right away, though it may take a few minutes to update in games you are currently playing.

How much the username change costs

The cost depends on your account age and how many times you have changed your username before. New accounts pay more than established ones. If you have changed your username multiple times, the price increases each time.

Roblox does not publish exact pricing, but the cost typically ranges from 1,000 to 10,000 Robux for most players. You can see the exact price before you confirm the change, so there are no surprises. If you do not have enough Robux, you will need to purchase more through the Roblox website before you can complete the change.

What happens to your old username

When you change your username, your old one becomes available for any other player to claim. This means if you change your mind later, you cannot get the same name back unless the new owner gives it up. Think carefully about your new username before confirming, because you cannot undo the change.

Your friends list, game progress, items, and Robux all stay with your account. Changing your username does not affect any of that. People who had you added as a friend will still see you on their friends list, though your name will update to the new one.

Troubleshooting: username change not working

If the Change button does not appear next to your username, you are likely still in your 30-day waiting period. Check the countdown timer — it shows exactly when you can change again. You cannot bypass this limit.

If you see an error message when you try to confirm the change, the most common reasons are: you do not have enough Robux, the username is already taken, or the name breaks Roblox's naming rules. Try a different username and make sure you have enough Robux in your account. If the problem continues, try logging out and back in, or use a different web browser.

Changing your username on mobile

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

Scroll down to find Account Settings and tap it. Look for the Username section and tap the button next to it. Follow the same steps as the desktop version: enter your new username, check the cost, and confirm. The change takes effect when ready on mobile and desktop.

Frequently Asked Questions

Can I change my username back to my old one?

Not directly. Once you change your username, the old one goes back into circulation and other players can claim it. If you want to use your old name again, you would have to wait for the person who claimed it to change theirs, then change yours to match — which is unlikely. Choose your new username carefully.

What if my username is already taken?

Roblox tells you when ready if a name is taken when you type it in. You will see a red message saying the username is unavailable. Try a different name. You can add numbers or underscores to make a variation of the name you want.

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

No. Your account keeps everything — all your games, items, Robux, and friends. Only your display name changes. People who play with you will see your new name, but your progress and inventory stay exactly the same.

How long does it take for my new username to show up everywhere?

It shows on your profile and in most places when ready, but it can take a few minutes to update in active games. If you are playing when you change it, you may see your old name until you rejoin the game.

Can I change my username more than once every 30 days?

No. Roblox enforces a 30-day waiting period between changes. This limit cannot be removed or bypassed, even if you contact Roblox support. You can see exactly when your next change is available in your account settings.
