You can change your Roblox username once every 30 days without paying anything

Roblox lets you change your username for free, but only once per month. You do this through your account settings on the Roblox website or mobile app — there is no separate tool, no code to buy, and no third-party site involved. The change takes effect when ready, though other players may see the old name briefly if they have cached it locally.

If you have never changed your username before, your first change is free. If you changed it recently, you will see a countdown timer showing when you can change it again. The 30-day window resets from the date of your last change, not from the first of the month.

Key Takeaways

  • You can change your Roblox username once every 30 days at no cost through your account settings.
  • The change happens when ready in your profile, though some players may see your old name cached for a few hours.
  • If you have already changed your username recently, the system will show you exactly when you can change it again.
  • Usernames must be between 3 and 20 characters, contain only letters, numbers, and underscores, and cannot start with a number.
  • If your desired username is taken, you cannot reserve it or put yourself on a waiting list — you will need to choose a different one.

Steps to change your username on desktop

Go to the Roblox website and sign into your account. Click the gear icon in the top right corner of the page, then select Settings from the dropdown menu.

On the Settings page, click the Account tab on the left side. You will see a section labeled Username with your current name displayed. Click the Change Username button next to it.

Type your new username into the text box. Roblox will tell you when ready if the name is already taken or breaks the naming rules. If the name is available, click Change Username to confirm. Your new name is now live.

Steps to change your username on mobile

Open the Roblox app and tap the three horizontal lines (menu icon) in the bottom right corner. Tap your username at the top of the menu to open your profile.

Tap the three dots in the top right corner of your profile screen, then select Settings. Scroll down and tap Account. You will see your current username with a Change button next to it.

Tap Change, enter your new username, and tap Change Username to save it. The change takes effect right away.

What usernames Roblox will not allow

Your username must be between 3 and 20 characters long. It can contain letters (uppercase and lowercase), numbers, and underscores only — no spaces, hyphens, periods, or special characters. Your username cannot start with a number.

Roblox also blocks usernames that contain profanity, impersonate staff members, or match certain reserved words. If you try to use a blocked name, the system will reject it and suggest that you choose something different. There is no way to appeal a blocked name or request an exception.

Why you might not see the change button

If you changed your username within the last 30 days, the Change Username button will be replaced with a timer showing how many days and hours remain before you can change it again. You cannot bypass this timer, and there is no way to change your username more than once per month even if you pay Robux.

If you are under 13 and your account has parental controls enabled, your parent or guardian may have restricted username changes. Check with them, or ask them to adjust your account settings in the Parent Dashboard.

What happens after you change your username

Your new username appears in your profile, on your posts, and in games when ready. However, other players may see your old username in their friends list or in chat for a few hours while their local cache updates. This is normal and does not mean the change failed.

Your user ID — a unique number assigned to your account — never changes. Games and scripts that reference your user ID will continue to work. Only the display name changes.

Frequently Asked Questions

Can I change my username more than once a month if I pay Robux?

No. The 30-day limit applies to all accounts regardless of how much Robux you own or spend. Robux is Roblox's premium currency and does not unlock faster username changes.

What if someone else takes the username I want?

Usernames are first-come, first-served. If a name is taken, you cannot reserve it or join a waiting list. You will need to choose a different username or wait to see if the other player changes their name in the future.

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

Yes, if no one else has claimed that old username. However, you still have to wait 30 days from your last change. You can change back to any available username you want.

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

Yes. Your user ID stays the same, so you remain in their friends list under your new name. They will see the new username the next time they open the app or refresh their friends list.

What if I see an error message when I try to change my username?

Common errors include: the name is taken, the name breaks the character rules, the name contains blocked words, or you have already changed it within 30 days. Read the error message carefully — it usually tells you which rule the name broke. Try a different username.
