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 web browser, 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 region but is typically under $10 USD), and confirm the change. Your new username takes effect when ready, though your old username becomes available for others to claim after 30 days.

Roblox limits how often you can change your username to prevent account takeovers and keep the username system stable. If you changed your username recently, you will need to wait until the 30-day window passes before you can change it again.

Key Takeaways

  • You must use a web browser to change your username — the mobile app does not have this feature.
  • Roblox charges a fee to change your username, and the amount depends on your region and account age.
  • You can only change your username once every 30 days, starting from the date of your last change.
  • Your old username becomes available for others to use 30 days after you change it.

Step-by-step process to change your username

Open a web browser and go to roblox.com. Log in with your email address and password. Once you are logged in, look for the gear icon in the top right corner of the page and click it to open the menu.

From the menu, select Settings. On the left side of the Settings page, click Account. You will see your current username displayed with a button or link next to it that says "Change" or shows an edit icon. Click that button to open the username change window.

Type your new username into the text box. Roblox will tell you right away if the name is already taken or if it breaks the content policy. If the name is available, you will see a green checkmark. Click the button to proceed to payment.

Enter your payment information or use Robux (Roblox's in-game currency) if you have enough. Complete the transaction. Your username changes when ready once payment goes through.

What happens to your old username after you change it

Your old username does not disappear right away. For 30 days after you change it, your old username is locked and cannot be used by anyone else. This protects you in case you made a mistake or want to change back quickly.

After 30 days, your old username becomes available for any other player to claim. If you want to keep that username, you would need to change back to it before the 30-day window closes. Changing back counts as a new username change, so you would have to wait another 30 days before changing again.

Username rules and restrictions

Roblox usernames can be 3 to 20 characters long and can include letters, numbers, and underscores. You cannot use spaces, special characters, or consecutive underscores. Usernames are not case-sensitive, so "MyName" and "myname" are treated as the same username.

Roblox filters usernames against a content policy that blocks names containing profanity, slurs, or references to illegal activity. If you try to use a name that violates the policy, the system will reject it and ask you to choose a different one. The rejection happens before you pay, so you will not be charged for an invalid name.

Cost of changing your username

The fee to change your username varies by region. In the United States, the cost is typically $4.99 USD, but prices are different in other countries. Roblox shows you the exact price in your local currency before you confirm the purchase.

You can pay with a credit card, debit card, PayPal, or Robux. If you use Robux, the cost is usually 1,000 Robux, though this can vary. Younger accounts or accounts with limited history may face higher fees or be unable to change their username at all.

If you cannot change your username

If the Change button does not appear in your Account settings, your account may not be old enough or may not have spent enough Robux to unlock the feature. Roblox requires accounts to meet certain conditions before allowing username changes. Very new accounts created within the last few days typically cannot change their username yet.

If you see an error message when you try to pay, check that your payment method is valid and that you have enough funds. If the problem continues, try a different payment method. If none of your payment methods work, contact Roblox support through the Help page on their website.

Frequently Asked Questions

Can I change my username on the Roblox mobile app?

No. Username changes are only available through the Roblox website on a computer or tablet web browser. Open roblox.com in Safari, Chrome, or another browser and follow the steps in your account settings.

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

Once your old username is claimed by someone else, you cannot get it back. If you think you might want to use that username again, change back to it within the 30-day window. After 30 days, it is gone for good.

Do I have to pay every time I change my username?

Yes. Each username change costs money, whether you are changing to a brand new name or changing back to an old one. Roblox charges the fee to prevent spam and account abuse.

Can I change my username if my account is banned or suspended?

No. If your account is suspended or banned, you cannot make any changes to it, including changing your username. You would need to resolve the suspension or ban first by contacting Roblox support.

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

Your new username appears when ready in your profile and in games once the payment goes through. Other players will see your new name right away in chat, on leaderboards, and in their friends list.
