You get one free username change, then Roblox charges for the next one

Roblox gives every account one free username change. After that, each change costs 1,000 Robux (the in-game currency). If you have not yet changed your username since creating your account, you can do it now at no cost. Once you use that free change, the next one will require payment.

The free change is a one-time offer per account, not something that resets. Plan your new username carefully, because if you change it again later, you will need to spend money. This guide walks you through using your free change before it is gone.

Key Takeaways

  • Every Roblox account gets exactly one free username change; after that, changes cost 1,000 Robux each.
  • You change your username in Account Settings on the Roblox website, not in the game itself.
  • The new username must be between 3 and 20 characters, contain only letters, numbers, and underscores, and not be taken by another player.
  • The change takes effect when ready, but your old username becomes available for others to claim after a short delay.
  • If you have already used your free change, there is no way to change your username without paying or creating a new account.

Where to find the username change option

Open a web browser and go to the Roblox website. Sign in to your account if you are not already logged in. Click the gear icon in the top right corner of the page — this opens your account menu.

From the dropdown menu, select Settings. On the Settings page, click the Account tab on the left side. You will see a section labeled Username with your current name displayed. Next to it is a button that says Change Username (or Change, depending on your browser). Click that button to proceed.

Rules for your new username

Roblox enforces specific rules about what usernames are allowed. Your new name must be between 3 and 20 characters long. It can contain letters (uppercase and lowercase), numbers, and underscores only — no spaces, hyphens, periods, or special characters.

The username you choose cannot already be taken by another player. When you type a name into the change box, Roblox tells you when ready whether it is available. If the name is taken, you will see a message saying so, and you can try a different one. Usernames are not case-sensitive, so "John" and "john" are treated as the same name.

Checking if your free change is still available

If you have never changed your username before, your free change is waiting. If you are unsure whether you have already used it, the Settings page will tell you. When you click Change Username, the system shows you whether the change is free or will cost 1,000 Robux.

If it says the change costs Robux, you have already used your free change on this account. At that point, your only options are to pay for the change or create a new Roblox account. There is no way to recover or reset the free change once it has been used.

What happens after you confirm the change

Once you type in your new username and confirm it is available, click the button to complete the change. The new name takes effect when ready — you will see it update on your profile and in games right away. Other players will see your new username when they look at your profile or encounter you in a game.

Your old username does not disappear when ready. Roblox holds it for a short period (usually a few days) before releasing it so other players can claim it. During that time, if you change your mind, you cannot get the old name back by changing again — you would have to pay for another change and hope the old name is still available.

Why you cannot change your username on mobile

The username change option only works on the Roblox website, not in the mobile app or on the Roblox website viewed on a phone browser. If you try to access Settings on your phone, you will not see the Change Username button. You must use a computer or tablet with a full web browser to make the change.

If you only have access to a phone, you can still change your username by opening the Roblox website in your phone's browser and requesting the desktop version of the site. Most phone browsers have an option to "Request Desktop Site" in the menu. Once you switch to desktop view, the Change Username button will appear.

What to do if your desired username is taken

If the username you want is already claimed, Roblox will not let you use it. You have two choices: pick a different name, or wait to see if the current owner abandons their account. Usernames from inactive accounts are sometimes released, but there is no way to know when or if that will happen.

Many players add numbers or underscores to make a name unique — for example, "john_2024" or "john123" instead of just "john". You can also try variations of your preferred name to find one that is available. Once you confirm your new username works, you cannot undo the change without paying, so make sure you are happy with it before you click confirm.

Frequently Asked Questions

Can I get my free username change back if I used it by accident?

No. Once you use your free change, it is gone permanently. Roblox does not restore free changes or offer refunds. If you changed your username and regret it, your only option is to pay 1,000 Robux for another change or create a new account.

What if I see the change button but it says I need Robux?

That means you have already used your free change on this account. Every account gets one free change only. If you want to change your username again, you will need to purchase 1,000 Robux through the Roblox website or app.

Does changing my username affect my games, friends, or Robux?

No. Your games, friend list, Robux balance, and all other account data stay exactly the same. Only your display name changes. Your friends will see your new username, but they do not need to re-add you or do anything on their end.

How long does it take for the username change to show up everywhere?

The change is when ready on your profile and in games. However, it may take a few minutes to update in other places like the Roblox website search or in chat logs. If you do not see your new name right away, refresh the page or close and reopen the game.

Can I change my username back to my old one for free?

Only if you have not used your free change yet. If you have already changed your username once, changing it back to the old one costs 1,000 Robux, just like any other change. Your old username also has to still be available — if someone else claimed it, you cannot use it again.
