You can change your Roblox username once every 30 days through your account settings

To change your username, log into your Roblox account on a web browser, go to your account settings, find the username field, and enter your new name. Roblox charges 1,000 Robux (the in-game currency) for each username change. The change takes effect when ready, and your old username becomes available for other players to claim after a short delay.

The process takes about two minutes. You cannot change your username more than once per month, and there are restrictions on what characters and words you can use. If you have never changed your username before, your first change costs the same as any other.

Key Takeaways

  • Username changes cost 1,000 Robux and can only happen once every 30 days.
  • You must access your account settings through a web browser — the mobile app does not have this option.
  • Your new username takes effect right away, but your old name stays reserved for a few hours before others can use it.
  • Roblox blocks usernames with certain words, numbers-only names, and names that look like impersonation attempts.

Step 1: Log in and navigate to account settings

Open a web browser and go to roblox.com. Click the circular profile icon in the top right corner and select Settings from the dropdown menu. You will see a list of options on the left side of the page. Click Account to open your account details.

If you are not logged in, click Log In at the top of the page and enter your username and password. You must be logged into the account you want to change — you cannot change someone else's username.

Step 2: Find and click the username field

In the Account settings page, look for the field labeled Username near the top. Next to it, you will see your current username and a pencil icon or Edit button. Click that icon or button to make the field editable.

Do not confuse this with your display name, which is a separate field below it. Your username is what appears in your profile URL and in-game chat. Your display name is what other players see as a label above your character in games.

Step 3: Enter your new username and check availability

Click in the username field and delete your current name. Type your new username. As you type, Roblox will show you whether the name is available or taken. A green checkmark means the name is free. A red X means someone else has it or it violates Roblox's naming rules.

Usernames can be 3 to 20 characters long and can include letters, numbers, and underscores. Roblox does not allow spaces, special characters other than underscores, or names that are all numbers. The system also blocks words it considers inappropriate or names that look like attempts to impersonate official Roblox accounts.

Step 4: Confirm you have 1,000 Robux and proceed

Before you can change your username, Roblox will tell you the cost: 1,000 Robux. Check your Robux balance in the top right corner of the page (it shows next to your profile icon). If you do not have 1,000 Robux, you will need to purchase more through the Roblox website or through the mobile app before you can change your name.

Once you have confirmed your new username is available and you have enough Robux, click the button to confirm the change. Roblox may ask you to re-enter your password for security. Do this and click confirm again.

Step 5: Wait for the change to process

Your new username takes effect when ready after you confirm. You will see it update on your profile page and in your account settings. The 1,000 Robux will be deducted from your balance right away.

Your old username becomes unavailable to other players for a few hours while Roblox's system updates. After that delay, someone else can claim it. You will not be able to change your username again for 30 days from the date of this change — Roblox counts the full calendar month, not 30 days from the exact time.

What to do if your username change fails

If you see an error message after clicking confirm, the most common cause is that someone claimed the username between the time you typed it and the time you submitted. Go back to step 3, choose a different name, and try again.

If the error says your account does not have permission to change usernames, your account may be too new or restricted. Roblox sometimes limits username changes on accounts that are fewer than 30 days old or accounts that have been flagged for rule violations. Wait a few days and try again, or contact Roblox support through the Help page on their website.

Frequently Asked Questions

Can I change my username on the Roblox mobile app?

No. The username change option only appears in the web version of Roblox. You must use a computer or tablet with a web browser. Open roblox.com in Safari, Chrome, Firefox, or Edge, log in, and follow the steps above.

What happens to my old username after I change it?

Your old username stays reserved for a few hours, then becomes available for other players to claim. You cannot get it back unless you change your username again and happen to choose it — but you would have to pay 1,000 Robux again and wait 30 days since your last change.

Do I lose my games, items, or friends if I change my username?

No. Your account, inventory, game progress, and friends list stay exactly the same. Only the name displayed changes. People on your friends list will see your new username the next time they log in.

Can I change my username more than once a month?

No. Roblox enforces a 30-day waiting period between username changes. If you changed your name on March 15, you cannot change it again until April 15 at the earliest. The timer resets each time you make a change.

Why is my username being rejected even though it looks normal?

Roblox blocks names that contain words it flags as inappropriate, names that look like impersonation attempts (such as "Roblox_Admin"), or names that are all numbers. Try adding an underscore, changing a letter, or choosing a completely different name. The system will show a red X if your choice is blocked.
