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 will need to spend 1,000 Robux (Roblox's in-game currency) each time you want a new name. You can change your username once every 30 days, so you cannot swap names repeatedly in a short period. The change takes effect when ready after you confirm it.

Before you change your name, understand that some games and friends may still see your old username briefly while their data updates. Your user ID — a number assigned to your account — never changes, so people who have you added as a friend will still find you. Any games you have played, items you own, and progress you have made stay with your account under the new name.

Key Takeaways

  • Changing your username costs 1,000 Robux and you can do it once every 30 days.
  • Your user ID stays the same, so friends can still find you even after you change your name.
  • You change your username in account settings under the "Account" tab, not in a game.
  • The name change takes effect right away, though some games may show your old name for a few hours while they refresh.
  • You cannot use a name that is already taken, contains banned words, or violates Roblox naming rules.

How to change your username step by step

Log into your Roblox account on the website or in the app. Go to the settings menu by clicking the gear icon in the top right corner of the screen. Select "Account" from the left sidebar menu.

Look for the "Username" section on the Account page. Click the "Change Username" button next to your current name. Type the new username you want into the text box. Roblox will tell you right away if the name is already taken or breaks the naming rules — you cannot use spaces, special characters, or numbers at the start of your name. Once you enter a name that is available, click "Buy for 1,000 Robux" to confirm the purchase and change.

Your new username is now active. If you do not have 1,000 Robux in your account, you will need to buy Robux before you can complete the change. Roblox sells Robux in bundles starting at small amounts, though the price per Robux is better if you buy larger bundles.

What happens to your old username after you change it

Your old username becomes available for someone else to use after you change it. There is no way to reserve it or get it back later. If you think you might want your old name again, wait before changing — once another person takes it, you cannot reclaim it.

Friends who have you added will still see you in their friends list under your new name. Games you have played will show your new username in leaderboards and chat, though some older games may take a few hours to update. Your profile page, which shows your games and items, will display your new name when ready.

Roblox username rules and what names you cannot use

Roblox has specific rules about what characters and words you can use in a username. You cannot start a username with a number, use spaces, or include special characters like underscores, hyphens, or periods. Your username must be between 3 and 20 characters long. Roblox will reject any name that contains words it has flagged as inappropriate or offensive.

You also cannot use a name that is already taken by another account. If you try to use a name that someone else has, Roblox will tell you it is unavailable and you will need to pick a different one. Some names that look similar to popular usernames or brand names may also be rejected, though Roblox does not always explain why a specific name was blocked.

If you cannot change your username or the change fails

If you see an error message when you try to change your username, the most common reason is that you do not have enough Robux. Check your Robux balance in the top right corner of the screen — you need exactly 1,000 Robux available. If your balance is lower, you will need to buy more Robux before you can proceed.

If you have enough Robux but the change still will not go through, try logging out and logging back in, then go to account settings again. Clear your browser cache if you are using the website, or restart the Roblox app if you are on mobile. If the problem continues, contact Roblox support through the Help page on the website and describe what error message you are seeing.

Another reason a change might fail is if the username you chose was taken by someone else between the time you typed it and the time you clicked confirm. Pick a different name and try again. If you are trying to change your username but the "Change Username" button does not appear, you may have changed your name within the last 30 days — you have to wait until the 30-day cooldown ends before you can change it again.

How to check when you can change your username again

Roblox enforces a 30-day waiting period between username changes. If you changed your username recently, you will not see the "Change Username" button in your account settings until the 30 days have passed. The button will reappear automatically once you are may be able to access to change again.

There is no way to see exactly how many days are left in the countdown, but you can check by going to your account settings and looking for the "Change Username" button. If it is not there, you are still in the waiting period. Mark the date you made your last change on a calendar so you know when you will be able to change again.

Frequently Asked Questions

Can I change my username for free?

No. Every username change costs 1,000 Robux, which is Roblox's paid currency. There is no way to change your username without spending Robux. If you do not want to pay, you will need to keep your current username.

Will my friends still be able to find me after I change my username?

Yes. Your user ID never changes, so anyone who has you added as a friend will still see you in their friends list under your new name. They can still message you and join your games. Your profile page will show your new username, and they can find you by searching for it.

What if someone takes my old username after I change it?

Once you change your username, your old name becomes available for anyone else to use. Roblox does not hold old usernames or let you reclaim them. If you think you might want your old name back, do not change your username. Once someone else takes it, it is gone permanently.

Can I change my username more than once a month?

No. You can only change your username once every 30 days. After you make a change, you have to wait a full month before you can change it again. There is no way to speed up this waiting period or change it more often.

What if the username I want is already taken?

You will need to pick a different name. Roblox will tell you when ready if a name is taken when you type it into the change box. You can try adding numbers or slight variations to the name you want, as long as the number is not at the start of the username.
