Change your username through the Roblox account settings
To change your Roblox username, go to your account settings on the Roblox website or app, find the username field, and enter a new name. Roblox lets you change your username once every 30 days. The first change is free; after that, each change costs 1,000 Robux (Roblox's in-game currency, which you buy with real money).
The steps are the same whether you use a computer or phone. Open Roblox, sign in to your account, and click the gear icon (settings) in the top right corner. Select "Account Settings," then find "Username" in the left menu. Click "Change Username," type your new name, and confirm the change.
Your new username takes effect immediately. Any games you own, friends you have, and items in your inventory stay attached to your account — only the name changes. Other players will see your new username the next time they look at your profile or encounter you in a game.

- Your username changes immediately, but your games, friends, and inventory remain the same.
- If your new username is already taken or violates Roblox rules, the system will reject it and ask you to choose a different one.
- You cannot change your username if you have not verified your email address on your account.
What usernames Roblox will not allow
Roblox blocks usernames that contain profanity, slurs, or hateful language. The system also rejects names that impersonate Roblox staff, famous people, or other well-known accounts — for example, you cannot use "Roblox" or "Administrator" as your username. Names that are already taken by another player will also be rejected.
If your chosen username is rejected, Roblox will tell you why and ask you to pick a different one. You can try again immediately; there is no penalty for rejected attempts. Keep in mind that Roblox's content filter is automated, so some rejected names may seem harmless to you — the system errs on the side of caution.
Usernames with special characters and numbers
Roblox usernames can include letters, numbers, underscores, and hyphens. You cannot use spaces, periods, or other special characters. If you want a username like "Player_123" or "Game-Fan," those are allowed. Usernames must be between 3 and 20 characters long.
Many players add numbers or underscores to their preferred name when the plain version is already taken. For example, if "Dragon" is taken, you might use "Dragon_1" or "Dragon123." This is a common workaround and does not violate any Roblox rules.
Changing your username on mobile versus desktop
The process is nearly identical on phone and computer. On mobile, open the Roblox app, tap the three-line menu icon at the bottom right, select your profile picture, and tap "Settings." Scroll down to "Account" and tap "Username." On desktop, use the gear icon in the top right corner and navigate to Account Settings the same way.
Mobile users sometimes report that the settings menu loads slowly or that the username field does not appear immediately. If this happens, close the app completely and reopen it. Make sure you are using the official Roblox app from the Apple App Store or Google Play Store, not a third-party app.
What happens if you forget to change your username before the 30-day window closes
If you change your username and then want to change it again, you must wait 30 days from the date of your last change. The system will show you a countdown timer in your account settings telling you exactly when you can change it next. You cannot change your username twice in one day, even if you pay Robux.
If you change your username and immediately regret it, you cannot undo the change directly. However, if you change it again after 30 days, you can use your old username — assuming no one else has claimed it in the meantime. Plan your username changes carefully, because once the 30-day window passes, your old name may be taken by another player.
Robux costs and payment methods
Your first username change is free. Every change after that costs 1,000 Robux. You can buy Robux through the Roblox website or app using a credit card, debit card, gift card, or other payment methods Roblox accepts in your country. Prices vary by region, but 1,000 Robux typically costs between $10 and $15 USD equivalent.
If you do not want to spend money on a username change, you can wait for special promotions. Roblox occasionally offers free Robux or discounted username changes during events or for new accounts, though these are not may provide. Check your account settings or the Roblox news feed to see if any current offers apply to you.
Frequently Asked Questions
Can I change my username if I have not verified my email?
No. Roblox requires email verification before you can change your username. If you have not verified your email, go to account settings, find "Email," and click the verification link Roblox sends you. This usually takes a few minutes.
What if someone else takes my old username after I change it?
Once you change your username, your old name becomes available for any other player to claim. If you want to use it again later, you will have to wait until that player changes their username or until Roblox recycles inactive accounts — which can take months or years. Choose your new username carefully.
Do my friends see my old username or my new one?
Your friends see your new username immediately. Their friend list updates automatically, and any messages or game invitations show your new name. Your old username disappears from their view entirely.
Can I change my username more than once every 30 days if I pay more Robux?
No. The 30-day waiting period is a hard limit that applies to all accounts, regardless of how much Robux you spend. You cannot bypass this restriction with payment.
What if Roblox says my username violates the rules but I do not think it does?
Roblox's filter is automated and sometimes rejects names that seem harmless. Try a slightly different version — add a number, change a letter, or use an underscore. If you believe the rejection is a mistake, you can contact Roblox support through your account settings, though response times vary.
