You can change your username once every 30 days without paying
Roblox lets you change your username for free once per month. You do not need to buy Robux or pay any fee — the change is built into your account settings. If you have never changed your username before, you get one free change when ready. After that, each change resets on a 30-day timer from the date you made the previous one.
The process takes about two minutes and happens when ready. Your new username becomes active right away across all your games, your profile, and your friends list. People who had you added as a friend will still see you — the friendship does not break when you change your name.
Key Takeaways
- You can change your Roblox username once every 30 days at no cost by going to Settings > Account > Username.
- Your new username takes effect when ready and appears everywhere — your profile, games, and friends' lists.
- Usernames must be between 3 and 20 characters and can only contain letters, numbers, underscores, and hyphens.
- If you try to change your username before 30 days have passed since your last change, the button will show you exactly when you can change it again.
- Changing your username does not affect your account security, your Robux balance, your games, or your friend list.
Step-by-step: changing your username on computer
Start by logging into your Roblox account on a web browser. Click the gear icon in the top right corner of the page — this opens your Settings menu. Select Account from the left sidebar.
Look for the Username section. You will see your current username displayed, and below it a text box where you can type a new one. Type the username you want. Roblox will check in real time whether that name is available — if it is taken, you will see a red message saying so. If it is available, the message will turn green and say "Username available."
Once you see the green message, click the Change Username button. The page will refresh, and your new username will appear at the top right of the screen where your old one was. You are done — the change is live.
Changing your username on mobile or tablet
Open the Roblox app and log in. Tap the three horizontal lines (the menu icon) in the bottom right corner. Scroll down and tap Settings.
Tap Account. You will see your username listed near the top. Tap on it to open the username change screen. Type your new username in the text box. The app will show you whether it is available — green means you can use it, red means it is taken.
Tap Change Username when you are ready. The app will update, and your new name will show in your profile when ready.
Rules for what your new username can be
Roblox usernames must be between 3 and 20 characters long. You can use letters (uppercase and lowercase), numbers, underscores, and hyphens. You cannot use spaces or special characters like periods, commas, or symbols.
Your username cannot be the same as someone else's username — Roblox checks this automatically and will tell you if the name is taken. You also cannot use a username that violates Roblox's community standards. Names that include slurs, hateful language, or references to illegal activity will be rejected, and Roblox will not tell you specifically why — it will just say the name is unavailable.
If you want a username that is currently taken, there is no way to reserve it or put yourself on a waiting list. Your only option is to check back periodically to see if the account holding that name becomes inactive. Roblox does not publicly state how long an account must be inactive before its username becomes available again.
What happens if you change your mind within 30 days
Once you change your username, you cannot change it again for 30 days. This timer starts from the moment you clicked the button, not from when you first created your account. If you realize you made a mistake, you are stuck with the new name until the 30 days are up.
There is no way to undo a username change or to contact Roblox support to reverse it. Plan your new username carefully before you confirm the change. If you are unsure, write it down and live with it for a day before you make the change official.
Paid username changes and what they are for
Roblox also offers a paid option: you can change your username more than once per month by spending 1,000 Robux. This costs real money — the exact dollar amount depends on how many Robux you buy at once, but 1,000 Robux typically costs between $10 and $12 USD.
The paid change follows the same rules as the free change — your new username must still be available, must follow the character rules, and takes effect when ready. The only difference is that you can do it as many times as you want if you keep paying. Most players never need this option. Use the free change once a month, and you will have all the flexibility you need.
Frequently Asked Questions
Will my friends still see me after I change my username?
Yes. Your friend list does not break when you change your username. Everyone who had you added will still see you in their friends list, and you will still see them in yours. Your username change does not affect any of your social connections on Roblox.
Can I change my username back to my old one?
Only if nobody else has taken it in the meantime. Once you change away from a username, it becomes available for anyone else to claim. If you want to go back to an old name, you will have to wait until the 30-day timer is up, then hope nobody else has grabbed it. If someone has, you cannot get it back.
What if the username I want is taken?
You cannot reserve it or request it. Try a variation — add a number, an underscore, or a short word to make it unique. If the exact name matters to you, you can check back occasionally to see if the account holding it becomes inactive, but Roblox does not publish how long that takes.
Do I lose my Robux or games if I change my username?
No. Your Robux balance, your game library, your inventory, and everything else on your account stays exactly the same. A username change only changes your name — nothing else is affected.
Can I change my username if my account is new?
Yes. You can change your username on a brand-new account. There is no waiting period or account age requirement. If you created an account and when ready want a different name, you can change it right away.
