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, but only once per month. You do this through your account settings on the Roblox website or app — there is no charge, and you do not need to buy anything. The change takes effect when ready after you confirm it.

The 30-day waiting period resets from the date you last changed your name, not from the calendar month. If you changed your username on March 15, you cannot change it again until April 15. This limit exists to prevent spam and account takeovers.

Key Takeaways

  • You can change your username once every 30 days without paying anything.
  • The change happens in your account settings under the "Account Info" tab, and takes effect right away.
  • Your new username must be between 3 and 20 characters, contain only letters, numbers, underscores, and hyphens, and cannot be taken by another player.
  • If you try to change your username before 30 days have passed, Roblox will show you the exact date you can change it again.
  • Changing your username does not affect your game progress, Robux balance, or friends list.

Steps to change your username on desktop

Go to the Roblox website and sign into your account. Click the gear icon in the top right corner and select "Settings" from the dropdown menu.

On the Settings page, click the "Account Info" tab on the left side. You will see a field labeled "Username" with your current name. Click the "Change Username" button next to it.

Type your new username into the box that appears. Roblox will tell you right away if the name is already taken or breaks the naming rules. Once you see a green checkmark saying the name is available, click "Change Username" to confirm.

Your new username is now active. You do not need to sign out and back in — the change shows up when ready in your profile and to other players.

Steps to change your username on mobile app

Open the Roblox app and tap the three horizontal lines (menu icon) in the bottom right corner. Tap your username at the top of the menu to go to your profile.

On your profile page, tap the gear icon to open settings. Scroll down and tap "Account Info." You will see your current username with a "Change Username" button next to it.

Tap the button, type your new username, and wait for Roblox to check if it is available. When you see the green checkmark, tap "Change Username" to finish.

Rules for choosing a new username

Your new username must be between 3 and 20 characters long. It can contain letters (uppercase and lowercase), numbers, underscores, and hyphens. Spaces are not allowed.

Roblox blocks usernames that contain profanity, impersonate famous people or brands, or look like they are trying to scam other players. If you try a name and it gets rejected, the site will tell you why. Common reasons include the name being taken, being too similar to a taken name, or containing blocked words.

You cannot use a username that was previously yours if someone else has claimed it in the meantime. Once you change away from a name, it becomes available to other players after a short delay.

What happens if you try to change too soon

If you attempt to change your username before 30 days have passed since your last change, Roblox will show you a message saying "You can change your username again on [date]." The date shown is exactly 30 days after your previous change.

There is no way to bypass this waiting period. Roblox does not offer paid username changes that skip the 30-day rule, despite what some third-party websites claim. If a site promises to change your username faster for money, it is a scam.

Your username versus your display name

Roblox has two separate name fields: your username and your display name. Your username is what you use to sign in and what appears in your profile URL. Your display name is what other players see in games and on your profile.

You can change your display name as often as you want, but it does not affect your login username. If you want a different name to show in games, you can change your display name in Account Info without waiting 30 days. The display name field is separate from the username field.

What does not change when you update your username

Your Robux balance, game progress, inventory items, and friend list all stay exactly the same. Games you have built, groups you own, and any trades you have made remain under your new username. Other players' friend lists automatically update to show your new name.

If you have a custom URL or profile link saved somewhere, it will no longer work after you change your username. You will need to update those links to use your new username. Your old username becomes available to other players after a few days, so do not count on being able to reclaim it.

Frequently Asked Questions

Can I change my username more than once a month?

No. Roblox enforces a strict 30-day waiting period between username changes. You cannot pay to skip this limit or change it faster. The timer resets from the date of your last change, not from the calendar month.

What if someone took my old username after I changed it?

Once you change away from a username, it becomes available to other players after a short delay. You cannot reclaim it unless the person who took it changes their name. If the username is important to you, do not change away from it unless you are sure you want something different permanently.

Is there a fee to change my username?

No. Roblox allows one free username change every 30 days. Any website or service claiming to change your username for a fee is not affiliated with Roblox and should not be trusted with your account information.

Can I change my username if my account is new?

Yes. There is no minimum account age required to change your username. You can change it as soon as you create your account, as long as you have not changed it in the past 30 days.

What if the username I want is taken?

Roblox will tell you when ready when you try to claim a taken name. You will need to choose a different username. You can try variations like adding numbers, underscores, or hyphens to make the name unique.
