Change your username through your account settings

To change your Roblox username, log into your account on the Roblox website, go to your account settings, and select the option to change your username. The process takes about two minutes and works the same way whether you're on a computer or phone. You'll need to know your current password to confirm the change.

Roblox lets you change your username once every 30 days at no cost. If you've already changed it recently, you'll see a countdown timer showing when you can change it again. The name you pick must be between 3 and 20 characters, can only use letters, numbers, and underscores, and cannot be a name already taken by another player.

Key Takeaways

  • You can change your username once every 30 days for free through your account settings on the Roblox website.
  • Your new username must be 3 to 20 characters long and can only contain letters, numbers, and underscores.
  • You will need to enter your current password to confirm the username change.
  • If you've already changed your username recently, you must wait 30 days from your last change before you can pick a new one.

Step-by-step: finding the username change option

Start by going to the Roblox website and logging in with your email and password. Once you're logged in, look for the gear icon or menu button in the top right corner of the page — this is usually next to your avatar picture. Click it and select "Settings" from the dropdown menu.

In Settings, click on the "Account" tab on the left side. You'll see several options listed, including "Username". Click on "Username" and you'll see your current name displayed with a button or link to change it. Click that button to open the change form.

Entering and confirming your new username

A text box will appear where you can type your new username. As you type, Roblox will tell you right away if the name is already taken or breaks the rules — for example, if it's too short, too long, or uses characters that aren't allowed. Keep typing until you see a green checkmark or message saying the name is available.

Once you've picked an available name, you'll need to enter your password in a separate field to confirm the change. This is a security step to make sure someone else hasn't gained access to your account. Type your password carefully, then click the button to save your new username. The change takes effect when ready.

What happens if you've already changed your username recently

Roblox enforces a 30-day waiting period between username changes. If you've changed your username within the last month, the username change option will still appear in your settings, but it will show a timer counting down the days and hours until you can change it again. You cannot bypass this timer or pay to change your username sooner.

The 30-day timer starts from the date you made your last change, not from the date you created your account. If you changed your username on March 15, you can change it again on April 15. During the waiting period, your current username stays the same and cannot be modified.

Rules for picking a new username

Your new username must follow Roblox's naming rules or the system will reject it. The name must be between 3 and 20 characters long — you cannot have a one-letter or two-letter username, and anything longer than 20 characters will be cut off. You can use uppercase and lowercase letters, numbers 0 through 9, and underscores, but no spaces, hyphens, periods, or special characters like @, #, or $.

The name you pick cannot already belong to another player. If you type a name that's taken, Roblox will show you a message saying so, and you'll need to pick something different. Usernames are not case-sensitive, so "JohnSmith" and "johnsmith" are treated as the same name. If someone already has "johnsmith", you cannot use "JohnSmith" either.

Changing your username on mobile devices

The process on a phone or tablet is nearly identical to the computer version. Open the Roblox app or go to the Roblox website in your mobile browser and log in. Tap the menu icon (usually three horizontal lines) in the top right or bottom of the screen, then tap "Settings". From there, tap "Account" and then "Username" to open the change form.

Enter your new username the same way you would on a computer, and Roblox will check availability in real time. When you're ready, enter your password and tap the button to confirm. The change happens right away, and your new username will show up everywhere on your profile and in games.

What to do if your desired username is taken

If the username you want is already taken, you have a few options. You can add numbers to the end of the name — for example, if "Alex" is taken, try "Alex123" or "Alex2024". You can also use underscores to separate words, like "Alex_Gaming" instead of "AlexGaming". Many players add their birth year or a number that's meaningful to them to make their username unique.

There is no way to reserve a username or put your name on a waiting list if someone else has it. You cannot contact Roblox to ask them to free up a username that's inactive. Your only option is to pick a different name that follows the rules and is not currently in use.

Frequently Asked Questions

Can I change my username more than once every 30 days?

No. Roblox enforces a strict 30-day waiting period between username changes, and there is no way to change it sooner or pay to bypass it. You must wait the full 30 days from your last change before you can pick a new username.

Will my friends still be able to find me after I change my username?

Yes. Your friends will see your new username in their friends list, and they can still message and play with you. Your profile, games, and inventory all stay the same — only the name changes. Your user ID, which is a number assigned to your account, never changes.

What if I change my username and then want to change it back?

You can change back to your old username, but you have to wait 30 days from when you made the first change. If you changed from "OldName" to "NewName" on March 1, you could change back to "OldName" on March 31 — but only if no one else has claimed that name in the meantime.

Does changing my username cost Robux or real money?

No. Changing your username is free and does not cost Robux, real money, or any in-game currency. Roblox allows one free username change every 30 days for all players.

Can I use special characters or spaces in my username?

No. Your username can only contain letters (A–Z, a–z), numbers (0–9), and underscores. Spaces, hyphens, periods, and special characters like @, #, $, or ! are not allowed and will cause the system to reject your choice.
