Yes, you can change your Roblox username, but the process depends on your account type and how many times you have changed it before

Roblox lets you change your username through your account settings. The steps are straightforward, but there are limits: you get one free username change, and after that, each change costs 1,000 Robux (Roblox's in-game currency). If you have never changed your username before, you can do it at no cost right now.

The username you choose must be between 3 and 20 characters, contain only letters, numbers, hyphens, and underscores, and cannot be already taken by another player. Roblox also blocks usernames that violate their community standards — so anything hateful, sexual, or impersonating a real person will be rejected.

Key Takeaways

  • Your first username change is free; every change after that costs 1,000 Robux, which you must purchase with real money or earn through Roblox Creator Exchange if you are a developer.
  • You can change your username once every 30 days, so you cannot switch back and forth rapidly if you change your mind.
  • The username must be 3 to 20 characters and can only use letters, numbers, hyphens, and underscores.
  • Roblox rejects usernames that are already taken, contain profanity, or appear designed to impersonate or harass another player.

How to change your username in Roblox

Open Roblox and log into your account. Click the gear icon in the top right corner of the screen to open settings, then select Account Settings. On the left side, click Account Info.

You will see your current username displayed. Click the Change Username button next to it. Type your new username into the box that appears. Roblox will tell you when ready if the name is already taken or violates community rules. If the name is available, you will see a green checkmark. Click Purchase if this is not your first change (you will be charged 1,000 Robux), or Change if it is your free change. Your new username takes effect right away.

Understanding the 30-day waiting period

After you change your username, you must wait 30 days before changing it again. This applies whether you paid Robux or used your free change. The 30-day timer starts the moment you confirm the new username, not when you click the button.

If you change your mind within those 30 days, you cannot switch back when ready. You will have to wait until the 30 days are up, then pay 1,000 Robux to change it again (since your free change is already used). Plan your username choice carefully, because changing it twice in a row is expensive.

What happens to your old username

When you change your username, your old name becomes available for other players to claim. This happens when ready. If you regret the change, someone else may have already taken your original username by the time you realize it. You cannot reserve or hold onto an old username.

Your account history, friends list, inventory, and game progress all stay with your account no matter what username you use. Other players who were your friends will still see you in their friends list under your new name. Games you created or played will still be linked to your account.

When Roblox rejects a username

Roblox blocks usernames for three main reasons: the name is already taken, it contains words or phrases that violate community standards, or it appears designed to impersonate or harass someone. The system checks these automatically when you type the name in.

If your chosen name is rejected, try a variation — add a number, use an underscore, or pick a different word entirely. Roblox does not tell you which specific rule your name broke, only that it is not allowed. If you believe your username was rejected by mistake, you can contact Roblox support through your account settings, but rejections are rarely overturned.

Robux costs and how to get them

If you have already used your free username change, you will need 1,000 Robux to change it again. Robux is purchased with real money through the Roblox website or app. The cost varies by how many Robux you buy at once, but 1,000 Robux typically costs around $10 USD. Prices may differ in other countries.

If you are a Roblox developer, you can earn Robux through the Creator Exchange program by selling items, games, or passes you have created. However, you cannot convert earned Robux directly into spending Robux — the Creator Exchange has its own separate currency system. For a username change, you will need to purchase Robux with money.

Changing your username on mobile

The process on mobile is nearly identical to desktop. Open the Roblox app, tap the three horizontal lines (menu) in the bottom right, then tap your username at the top. Select Account Settings, then Account Info. Tap Change Username and follow the same steps as on desktop.

Make sure you are connected to a stable internet connection before starting, because interrupting the process mid-change can cause errors. If the change fails, wait a few minutes and try again.

Frequently Asked Questions

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

Only if no one else has claimed it in the meantime. When you change your username, your old name becomes available when ready. If someone else takes it, you cannot get it back. You would have to contact that player and ask them to change their name, which they are under no obligation to do.

What if I change my username and then want to change it again the next day?

You cannot. The 30-day waiting period is mandatory and starts the moment you confirm your new username. You must wait the full 30 days, then pay 1,000 Robux to change it a second time. Plan your username carefully to avoid this cost.

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

Yes. Your friends list updates automatically, and your friends will see your new username the next time they log in or refresh their friends list. Your account history and all your games stay linked to you under the new name.

What if Roblox says my username is inappropriate but I think it is fine?

Roblox uses automated filters and human review to block usernames that violate community standards. If you believe your username was rejected incorrectly, you can contact Roblox support through your account settings and explain why you think the name should be allowed. However, most rejections are not overturned.

Can I buy a username that someone else has?

No. Usernames cannot be bought, sold, or traded. Each username belongs to the account that claims it. If you want a specific username, your only option is to wait and hope the person who has it changes their name and you claim it before someone else does.
