Roblox lets you change your username once every 30 days, with some exceptions for new accounts

You can change your Roblox username once per calendar month. After you change it, you must wait at least 30 days before changing it again. This 30-day window resets on the same date each month — so if you change your username on March 15, you cannot change it again until April 15 at the earliest.

New accounts have a different rule. If your account is fewer than 30 days old, you can change your username once for free without waiting. After that first change, the standard 30-day waiting period applies.

Each username change costs 1,000 Robux, which is Roblox's in-game currency. You purchase Robux with real money through the Roblox website or app. The only exception is that first free change on brand-new accounts.

Key Takeaways

  • You can change your username once every 30 days, and each change costs 1,000 Robux except for the first free change on new accounts.
  • The 30-day timer resets on the calendar date you made your last change, not 30 days from the exact time you changed it.
  • Your old username becomes available for other players to claim after you change yours, usually within a few hours.
  • Changing your username does not affect your account security, your friends list, or your game progress.
  • If you change your username and then want to change it back, you still have to wait 30 days and pay 1,000 Robux again.

What happens to your old username after you change it

When you change your username, your old one does not stay reserved for you. Other players can claim it almost when ready — usually within a few hours. If you want to use that username again later, you would have to wait for someone else to abandon it, which is unpredictable and may never happen.

This is why many players write down their old usernames or take screenshots before changing them, especially if they had a username for years. There is no way to "reclaim" an old username through Roblox support, even if you were the original owner.

How to check when you can change your username next

To see when your next username change becomes available, go to your account settings on the Roblox website. Click on your profile icon in the top right, select Settings, then choose Account. Look for the username field — if you are within the 30-day waiting period, you will see text that says something like "You can change your username on [date]."

If that message does not appear and the username field is clickable, you are able to change your username right now. The Roblox mobile app shows the same information in its account settings menu.

Why Roblox enforces the 30-day rule

The 30-day limit exists to prevent account takeovers and fraud. If someone gains access to your account, they cannot when ready change your username and disappear. The waiting period gives you time to notice the breach and recover your account before your identity is fully changed.

The cost of 1,000 Robux also serves as a friction point — it makes username changes deliberate rather than casual, and it discourages people from cycling through usernames to evade bans or scams.

What does not change when you change your username

Your account ID, friends list, game progress, and Robux balance all stay exactly the same. Your friends will see your new username in their friends list, but they do not have to re-add you. Any games you have played, items you own, or achievements you have earned remain on your account.

If you are in a group or a game where your username is displayed, it will update to show your new name. Old chat messages or forum posts you made under your old username will still show that old name, because those are historical records.

Changing your username on console or mobile

You can change your username from the Roblox mobile app or from a console like Xbox or PlayStation, but the process is the same as on the website. Open your account settings, find the username option, and follow the prompts. The 30-day rule and the 1,000 Robux cost explore no matter which device you use.

If you are playing on console, you may need to sign into the Roblox website separately to manage your username, depending on how your account is linked. The mobile app usually handles it directly within the settings menu.

What to do if you cannot change your username

If the username field is grayed out or locked, you are still within your 30-day waiting period. The date when you can change it next should appear on the same screen. If you see an error message instead, try logging out and logging back in, or clear your browser cache and try again.

If you believe your account has been compromised and someone else changed your username without your permission, contact Roblox support through the Help page on the Roblox website. Provide as much detail as you can about when you last used your account and what username you had. Roblox support can investigate, but they cannot undo a username change — they can only help you regain access to your account.

Frequently Asked Questions

Can I change my username more than once in 30 days if I pay extra Robux?

No. The 30-day waiting period is a hard limit that applies to everyone, regardless of how much Robux you have or how much you are willing to spend. You cannot bypass it by paying more money.

If I change my username and then change it back, do I have to pay twice?

Yes. Each username change costs 1,000 Robux and counts as a separate change. If you change from "Player1" to "Player2" and then back to "Player1", you pay 1,000 Robux each time and must wait 30 days between each change.

What if someone else takes my old username after I change mine?

Once you change your username, you have no claim to the old one. If someone else claims it, there is nothing Roblox support can do to give it back to you. This is why some players create a second account and claim their old username on it if they want to preserve it.

Does changing my username affect my Roblox account security?

No. Your account security depends on your password and two-factor authentication settings, not your username. Changing your username does not make your account more or less find, though the 30-day waiting period does protect you if someone else gains unauthorized access.

Can I see a history of all the usernames I have used?

Roblox does not provide a public history of your past usernames. Only you can see your current username in your account settings. If you want to keep track of usernames you have used, you would need to write them down yourself.
