You can change your Roblox username once every 30 days at no cost through your account settings

Roblox lets you change your username for free once per month. You do not need to buy Robux or pay any fee. The change takes effect when ready, and your old username becomes available for other players to claim after a short period. You make the change directly in your account settings on the Roblox website or app — there is no separate form or approval process.

The 30-day waiting period resets each time you change your name. If you changed your username on March 15, you cannot change it again until April 15. This limit applies whether you paid for a name change or used your free monthly change.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • The change happens when ready in your account settings on the Roblox website or mobile app.
  • Your old username becomes available for other players to use after a few days.
  • If you have already used your free change this month, you must wait until the 30-day period ends before changing again.
  • Roblox does not refund Robux spent on paid username changes, even if you change your mind the same day.

Steps to change your username on the Roblox website

Go to the Roblox website and sign into your account. Click the gear icon in the top right corner, then select Settings. On the left side, click Account. You will see a section labeled Username with your current name displayed.

Click the Change Username button next to your name. Type your new username in the text box. Roblox will tell you when ready if the name is already taken or contains words it does not allow. Once you enter a name that is available, click Change Username to confirm. The change takes effect right away, and you will see your new name the next time you refresh the page or log out and back in.

Steps to change your username on the Roblox mobile app

Open the Roblox app and tap the three horizontal lines (menu icon) at the bottom right. Tap your username or profile picture at the top of the menu. Scroll down and tap Settings. Tap Account, then scroll to find Username.

Tap Change Username. Enter your new username and check that it is available. Tap the checkmark or confirm button to save the change. Like the website, the change is when ready, though it may take a moment to appear across all Roblox services if you are playing a game at the same time.

What happens to your old username

When you change your username, Roblox holds your old name for a few days before releasing it. During this time, no one else can take it. After that period ends — usually between three and seven days — another player can claim the old name. You cannot reclaim an old username unless it has not been taken by someone else.

Any games, items, or friends you had under your old username stay with your account. Your user ID, which is a number assigned to your account, never changes. Games and friends are tied to your user ID, not your username, so changing your name does not affect your progress or relationships in games.

Why your username change might not work

If you see a message saying you cannot change your username, the most common reason is that you have already used your free change within the last 30 days. Check the date of your last change — if it was fewer than 30 days ago, you must wait until that date passes. The system will tell you the exact date you can change again.

Another reason the change might fail is that the username you chose is already taken, contains banned words, or violates Roblox naming rules. Usernames cannot include spaces, special characters (except underscores), or words that Roblox flags as inappropriate. If you see an error, try a different name. You can also check whether a name is available by typing it in the change box — Roblox will tell you before you confirm.

The difference between free and paid username changes

Roblox offers both a free monthly change and a paid option using Robux, the in-game currency. The free change is the same as the paid one — there is no difference in how it works or how long it takes. The only difference is cost. If you have already used your free change this month and want to change your name again before the 30 days are up, you can pay Robux to do so when ready. The price varies but is usually between 1,000 and 1,500 Robux.

Roblox does not refund Robux spent on a paid username change. If you change your mind after paying, you cannot get your Robux back. For this reason, it is worth waiting for your free monthly change if you are not certain about the new name.

Troubleshooting: Your username change did not save

If you clicked confirm but your username did not change, try signing out and signing back in. Sometimes the change takes a moment to sync across Roblox servers. Refresh the page or close and reopen the app. Check your account settings again to see if the new name appears.

If the name still has not changed after 10 minutes, clear your browser cache or app cache and try again. On a computer, you can usually do this by pressing Ctrl+Shift+Delete (Windows) or Command+Shift+Delete (Mac), then selecting the option to clear cache. On a mobile app, go to your phone's Settings, find the Roblox app, and tap Clear Cache. Then open Roblox again and check your username.

Frequently Asked Questions

Can I change my username more than once a month?

You can change your username once every 30 days for free. If you want to change it again before 30 days have passed, you must pay Robux. The paid option costs between 1,000 and 1,500 Robux depending on your account age and region.

What if someone takes my old username?

Once another player claims your old username, you cannot get it back. Roblox does not reserve old usernames permanently. If you want to keep a username, do not change it. If you do change it and later want the old name back, you would have to ask the current owner to change theirs, which they are unlikely to do.

Does changing my username affect my games or friends?

No. Your user ID stays the same, and all your games, items, and friends are tied to that ID, not your username. Everyone on your friends list will still see you as a friend, and your game progress will not change. Other players will see your new username in games and on your profile.

Why does Roblox say my username contains banned words?

Roblox filters usernames for words it considers inappropriate or against its rules. The filter is automatic and sometimes blocks names that seem harmless. If your chosen name is rejected, try removing numbers, changing the spelling slightly, or picking a different name entirely. You can test names in the change box to see which ones are allowed.

Can I change my username if my account is new?

Yes, you can change your username on a new account. There is no minimum age requirement for username changes. However, very new accounts (less than a few days old) may have restrictions on other account features, so if you cannot change your username, wait a day or two and try again.
