The Basic Process: What Happens When You Change Your Name
You can change your Roblox username through your account settings on the website or mobile app. The change takes effect when ready — your old name disappears and your new one shows up in games, on your profile, and in chat. You do not need to create a new account or restart anything.
Roblox lets you change your username once every 30 days. If you changed it recently, you will see a countdown timer telling you when you can change it again. The first username change is free; after that, each change costs 1,000 Robux (the in-game currency you buy with real money).
Your user ID — a number assigned when you created your account — never changes. Friends who have you added will still see you in their friends list after you change your name, and games you own stay yours. Only the display name changes.
Key Takeaways
- You can change your username once every 30 days, with the first change free and later changes costing 1,000 Robux each.
- The change happens when ready across all Roblox games and your profile, but your user ID stays the same so friends keep you added.
- You make the change in account settings on the Roblox website or mobile app, not in a game.
- Usernames must be between 3 and 20 characters, cannot contain spaces, and cannot be offensive or already taken by another player.
Changing Your Username on the Website
Go to www.roblox.com and log in to your account. Click the circle with your current username or avatar in the top right corner of the page. A dropdown menu will appear with several options.
Select Settings from that 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 right away if the name is already taken or breaks the rules (spaces, offensive words, or too short). Once you see a green checkmark saying the name is available, click Change It to confirm. If you have changed your name in the last 30 days, you will be asked to pay 1,000 Robux instead.
Changing Your Username on Mobile
Open the Roblox app on your phone or tablet and log in. Tap the three horizontal lines (the menu icon) in the bottom right corner of the screen. Scroll down and tap Settings.
Tap Account in the Settings menu. You will see your username listed near the top. Tap Change Username below it. Enter your new name in the box that appears, and the app will show you whether it is available. Tap Change It to finish.
The mobile process works the same way as the website — your first change is free, and you can only change once every 30 days. If you are on mobile and do not see the option, make sure you are logged in and your app is up to date.
Rules for Your New Username
Your username must be between 3 and 20 characters long. You can use letters, numbers, and underscores, but not spaces or special characters like hyphens, periods, or symbols. Roblox will reject any name that contains profanity or is designed to impersonate another player or celebrity.
The name cannot already be taken by someone else. If you see "This username is taken" when you try to claim it, that exact name belongs to another account. You will need to choose something different. Roblox does not hold usernames for inactive accounts, so popular names get claimed quickly.
You cannot use a name that looks too similar to an existing one just to confuse people — for example, replacing the letter O with the number 0. Roblox moderators review flagged names, and using tricks to get around the rules can result in your account being suspended.
What Happens If You Do Not Have 1,000 Robux
Your first username change is always free. If you want to change it again and do not have 1,000 Robux saved up, you have two options: buy Robux with real money, or wait until your 30-day cooldown is over and try a different name that might be free to change.
Robux are sold in bundles starting at $4.99 for 400 Robux. A username change costs 1,000 Robux, so you would need to buy at least the $9.99 bundle (1,000 Robux) or higher. Some players earn Robux through games they create, but earning enough for a username change this way takes a long time.
If you are under 13, your account may have restrictions that prevent you from buying Robux without a parent or guardian's permission. Check your account settings to see if parental controls are turned on.
Troubleshooting Common Problems
If you see "You must wait X days before changing your username again," you are still in your 30-day cooldown from your last change. The timer counts from the exact time you made the previous change, not from midnight. You cannot change your name twice in one month no matter what.
If the name you want is rejected as "unavailable" or "taken," someone else already has it. Try adding a number or underscore to make it unique — for example, if "Alex" is taken, try "Alex_2024" or "Alex123." Roblox does not have a waitlist for usernames, so you cannot reserve a name that is currently taken.
If you changed your username but it is not showing up in games, log out completely and log back in. Sometimes the change takes a few minutes to sync across all servers. If it still does not show after 10 minutes, restart the game or app.
What Does Not Change When You Change Your Username
Your user ID stays the same forever. This is the number Roblox uses to track your account behind the scenes. Friends who have you added will still see you in their friends list even after you change your name — the friendship is tied to your user ID, not your username.
Games you own, Robux you have, and items in your inventory do not go anywhere. Your game history, achievements, and any money you have spent stay attached to your account. The only thing that changes is the name other players see when they look at your profile or meet you in a game.
If you are a content creator or streamer, changing your username does not affect your channel or followers on other platforms. Your YouTube, Twitch, or Discord accounts are separate from your Roblox account and do not update automatically.
Frequently Asked Questions
Can I change my username back to my old one?
Yes, but only after 30 days have passed since you changed away from it, and only if no one else has claimed it in the meantime. If someone took your old name, you cannot get it back unless they change their username and it becomes available again.
What if someone else is using a name similar to mine?
Roblox allows similar names as long as they are not identical. If someone is impersonating you or using a name designed to confuse people into thinking they are you, report them through the "Report Abuse" button on their profile. Moderators will review the report and take action if the name violates the rules.
Do I lose my friends when I change my username?
No. Your friends stay added because the friendship is tied to your user ID, which never changes. They will see your new username the next time they log in, but you will still be in their friends list.
Can I change my username if my account is under 13?
Yes, but parental controls may restrict your ability to spend Robux. If you want to change your username a second time and need to buy Robux, a parent or guardian may need to approve the purchase depending on your account settings.
What happens if I change my username and then want to change it again when ready?
You have to wait 30 days from the time you made the last change. The cooldown is strict — you cannot pay extra Robux to skip the wait. After 30 days, you can change it again for 1,000 Robux (unless it is your second change ever, in which case the first change is still free).
