You can change your username once every 30 days through your account settings
To change your Roblox username, log into your account on the Roblox website, go to your account settings, find the "Change Username" option, and enter your new name. The system will tell you when ready if the name is taken or violates Roblox rules. Once you confirm the change, your new username takes effect right away, though other players may see the old name briefly while the system updates across all servers.
The process takes less than a minute if your chosen name is available. Roblox limits you to one username change every 30 days, so you cannot change it again until that period passes. If you change your mind within a few minutes, you can change it back, but that still counts as using your one change for the month.
Key Takeaways

- Your new username takes effect when ready, though it may take a few minutes to show up in games and on other players' screens.
- Usernames must be between 3 and 20 characters and cannot contain spaces or special characters except underscores.
- If your chosen name is already taken or breaks Roblox content rules, the system will reject it and suggest you try a different one.
Step-by-step: changing your username on desktop
Open a web browser and go to roblox.com. Click the "Log In" button in the top right corner if you are not already signed in, then enter your username or email and password. Once you are logged in, click your avatar icon in the top right corner and select "Settings" from the dropdown menu.
In Settings, click the "Account" tab on the left side. Look for the section labeled "Username" and click the "Change" button next to it. Type your new username in the text box that appears. Roblox will check in real time whether the name is available and whether it follows the rules. If the name is available, a green checkmark appears. Click "Change Username" to confirm.
Your new username is now active. You will see it displayed in your account settings when ready. In games and on other players' profiles, it may take a few minutes to update everywhere, but the change is permanent once you confirm it.
What names Roblox will and will not allow
Roblox usernames must be between 3 and 20 characters long. You can use letters (A–Z), numbers (0–9), and underscores, but not spaces or other special characters like hyphens, periods, or symbols. The system rejects names that are already taken by another player, even if that player has not logged in for years.
Roblox also blocks usernames that contain words or phrases it considers inappropriate, hateful, or that reference real people without permission. If you try to use a name that breaks these rules, the system will show an error message and suggest you try something different. The blocked words change over time as Roblox updates its filters, so a name that worked years ago might be rejected now.
What happens to your old username after you change it
Your old username becomes available for other players to claim after you change it. There is no grace period — as soon as your new username takes effect, another player can register your old name. This means if you change your mind later, you cannot get your exact old username back unless the new owner gives it up.
Your account history, friends list, and game progress stay with your account no matter what username you use. Other players who have you added as a friend will see your new username the next time they log in. Games you have created or items you own remain yours, but they will now show your new username as the creator or owner.
Changing your username on mobile or tablet
The Roblox mobile app does not have a built-in username change feature. You must use a web browser on your phone or tablet instead. Open Safari, Chrome, or your default browser and go to roblox.com. Log in with your account, then follow the same steps as the desktop version: tap your avatar icon, select Settings, click Account, and find the Username section.
The mobile website works the same way as the desktop version, though the layout is narrower. If you have trouble finding the Settings option on mobile, make sure you are logged in first — the menu only appears when you are signed into your account.
If your username change does not go through
If you see an error message when you try to change your username, the most common reasons are that the name is already taken, it contains blocked words, or you have already used your one change for the month. The error message usually tells you which problem occurred. If the name is taken or blocked, try a different username. If you have already changed your username recently, you will need to wait until 30 days have passed since your last change.
In rare cases, account restrictions can prevent you from changing your username. This happens if your account has been flagged for violating Roblox rules. If you believe your account was restricted by mistake, you can contact Roblox support through the Help page on the website. Explain your situation and they will review your account.
Why Roblox limits you to one change per month
The 30-day limit exists to prevent players from impersonating others or evading bans. If players could change usernames constantly, someone could take on a famous player's name, cause trouble, then switch to a new name to avoid consequences. The monthly limit makes it harder to do this repeatedly and gives Roblox time to catch accounts that are breaking rules.
The limit also helps other players recognize you over time. If your friends or teammates could not count on your username staying the same, it would be harder to build a reputation or maintain relationships in games. The 30-day window balances the ability to rebrand yourself with the need for stability in the community.
Frequently Asked Questions
Can I change my username if I have not played in a long time?
Yes. Your ability to change your username is not affected by how long it has been since you last played. As long as your account is active and not restricted, you can change your username whenever you want, as long as you wait 30 days between changes.
What if someone else took my old username after I changed it?
Once you change your username, your old one becomes available when ready and you cannot claim it back. If another player registered it, you would need to contact that player and ask them to change their username so you could take it back — but they have no reason to do so. Choose your new username carefully because you may not be able to get your old one back.
Do I lose my Robux or game progress when I change my username?
No. Your Robux balance, game progress, friends list, and all items stay with your account. Only the name displayed changes. Everything else remains exactly the same.
Can I change my username more than once a month?
No. Roblox allows one username change every 30 days. If you change your username and then change your mind, changing it back still counts as your one change for the month. You will have to wait 30 days from your last change before you can change it again.
What if the username I want is taken?
Try a different name. You can add numbers, underscores, or slight variations to make it unique. The system will tell you when ready whether a name is available, so you can keep trying different options until you find one that works.
