Yes, you can change your Roblox username, but it costs Robux and has limits

Roblox lets you change your username through your account settings, but the change is not free. You pay 1,000 Robux (the in-game currency) each time you change it. You can change your username once every 30 days, so you cannot swap it back and forth on a whim. The change takes effect when ready after you pay and confirm it.

The username you choose must be between 3 and 20 characters long, contain only letters, numbers, and underscores, and cannot be already taken by another player. Roblox also blocks usernames that violate their community standards — profanity, impersonation of real people, and hate speech will be rejected during the change process.

If you have never changed your username before, Roblox gives you one free change. This is a one-time offer, so use it carefully if you created your account with a name you now dislike.

Key Takeaways

  • Your first username change is free, but every change after that costs 1,000 Robux.
  • You can only change your username once every 30 days, regardless of whether you paid or used your free change.
  • Your new username must be 3 to 20 characters, use only letters, numbers, and underscores, and cannot already belong to another player.
  • The change happens when ready after you confirm it and pay, and your old username becomes available for other players to claim.

Where to change your username in account settings

Open Roblox in your web browser and log into your account. Click the gear icon in the top right corner to open your settings menu, then select Account from the left sidebar. You will see a section labeled Username with your current name displayed.

Click the Change Username button next to your current name. A box will appear where you can type your new username. Type the name you want, and Roblox will tell you when ready whether it is available or violates community rules. If the name is available and acceptable, you will see a button to proceed to payment.

On the payment screen, Roblox will show you the cost (1,000 Robux if you have already used your free change, or 0 Robux if this is your first change). Confirm the purchase, and your username will change right away. You will be logged out and asked to log back in with your new username.

How to get Robux to pay for a username change

Robux is Roblox's currency, and you buy it with real money through the Roblox website or mobile app. Go to the Robux section in your account settings and select how much you want to buy. Roblox offers packages ranging from 400 Robux for about $5 to 40,000 Robux for about $200, though prices vary slightly by region and payment method.

You can also earn Robux by creating games or items in Roblox Studio and selling them to other players, but this takes time and requires you to build something people want to buy. For a quick username change, buying Robux directly is the fastest route.

If you are under 13, your account may have restrictions on buying Robux or spending it without parental permission, depending on your account settings. Ask the adult managing your account to help you purchase Robux if you cannot do it yourself.

What happens to your old username after you change it

Once you change your username, your old name is released back into the pool of available usernames. Other players can claim it when ready. This means if you change your mind within seconds, you might not be able to get your old name back — someone else could have already taken it.

Your account history, friends list, games you have created, and items you own all stay with your account. Changing your username does not reset or delete anything. Other players will see your new username in games and on your profile, but your user ID (a number assigned to your account) never changes.

Why Roblox charges for username changes and the 30-day wait

The 1,000 Robux fee and 30-day cooldown exist to prevent spam and account abuse. Without a cost and a waiting period, players could change their names constantly to evade moderation, impersonate others, or confuse their friends. The fee makes name changes intentional rather than casual.

The 30-day limit also protects players from account takeovers. If someone gains access to your account, they cannot when ready change your username and lock you out. The waiting period gives you time to regain control and change your password before your name is altered.

Usernames you cannot use

Roblox blocks usernames that contain profanity, slurs, or hate speech. The system also rejects names that impersonate real celebrities, public figures, or Roblox staff members. Names that are too similar to existing popular usernames may also be flagged, though Roblox does not publish an exact rule for what counts as "too similar."

If you try to change to a name that violates these rules, Roblox will show you an error message and let you try a different name. You will not be charged Robux for a failed attempt, so you can experiment with different options until you find one that works.

What to do if your username change fails or gets stuck

If you paid for a username change but it did not go through, check your Robux balance. If the Robux were deducted but your username did not change, log out and log back in — sometimes the change takes a moment to sync. If your username is still the same after logging back in, contact Roblox support through the Help section in your account settings.

Roblox support can see your transaction history and will refund your Robux if the change failed on their end. Provide them with the date and time you attempted the change, and they will investigate. Response times vary, but most issues are resolved within a few days.

Frequently Asked Questions

Can I change my username on mobile?

Yes. Open the Roblox app, tap the three-line menu icon, go to Settings, then Account, and select Change Username. The process is the same as on a computer, and you will be charged the same amount of Robux.

What if someone took my old username right after I changed it?

You cannot get it back unless that player changes their username or the account is deleted. Usernames are first-come, first-served once they are released. If the name is important to you, you could try messaging the player who took it and offering to trade, but Roblox does not have an official name-trading system.

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

No. Your account stays the same — only the name displayed changes. Your friends list, created games, owned items, and Robux balance all remain exactly as they were. People on your friends list will see your new username the next time they log in.

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

Only if no one else has claimed it. Since old usernames become available when ready after you change them, someone else may have already taken it. If they have not, you can change back to it, but you will pay 1,000 Robux again and have to wait 30 days from your last change.

What if I am under 13 and cannot buy Robux?

Ask the adult managing your account to purchase Robux for you. If your account has parental controls enabled, you may need their permission or password to complete the purchase. Alternatively, you could wait until your account is no longer restricted, though Roblox does not publish the exact age at which restrictions lift.
