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

Roblox lets you change the name on your account once per month. The process takes about two minutes and costs 1,000 Robux — the in-game currency you buy with real money. You do this through your account settings on the Roblox website or app, not through a game itself.

The 30-day waiting period starts the moment you confirm your new name. If you change your username on March 15, you cannot change it again until April 15. This limit exists to prevent account takeovers and spam, so Roblox enforces it strictly.

Key Takeaways

  • Changing your username costs 1,000 Robux and can be done once every 30 days through your account settings.
  • You must be at least 13 years old to change your username; younger accounts cannot change theirs.
  • Your new username must be between 3 and 20 characters, contain only letters, numbers, underscores, and hyphens, and cannot be already taken.
  • After you confirm the change, your old username becomes available for other players to claim after a short delay.
  • If you do not have enough Robux, you can buy more through the Roblox website using a credit card, gift card, or other payment method.

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 of the page, then select "Settings" from the dropdown menu. On the left side, click "Account" to open your account details.

Look for the "Username" section near the top of the page. Click the "Change" button next to your current username. A box will appear asking you to enter your new name. Type the name you want, then click "Check Availability" to see if someone else is already using it. If the name is available, you will see a green checkmark. If it is taken, you will see a red X and need to try a different name.

Once you have found an available name, click "Buy for 1,000 Robux" to confirm the purchase and change. Roblox will charge your account when ready. Your new username will be active right away, though it may take a few minutes to show up everywhere on the site.

Steps to change your username on mobile

Open the Roblox app and sign in. Tap the three horizontal lines (the menu icon) in the bottom right corner. Scroll down and tap "Settings," then tap "Account."

Tap "Username" to open the change screen. Enter your new name in the box that appears and tap "Check Availability." If the name is free, you will see a green checkmark. Tap "Buy for 1,000 Robux" to complete the change. The new username takes effect when ready.

Rules for choosing a new username

Your username must be between 3 and 20 characters long. You can use uppercase and lowercase letters, numbers, underscores (_), and hyphens (-). Spaces are not allowed. Roblox blocks usernames that contain profanity, impersonate famous people or brands, or violate their community standards.

If you try a name and Roblox says it is unavailable, someone else already has it. You cannot reserve a name or put it on a waiting list. You have to choose a different one. Common names, short names, and names that look like real words fill up quickly, so be ready with a few options.

What happens to your old username

When you change your username, your old one does not disappear forever. Roblox holds it for a period of time before releasing it to the public. During that time, no one else can claim it. After the hold expires — usually within a few weeks — other players can take it.

Your friends will see your new username in their friend list right away. Any games you created, items you own, and Robux you have will stay on your account. Your profile history and past messages will still be tied to your account, though they will show your new name.

If you do not have enough Robux

You need 1,000 Robux to change your username. If your account does not have that much, you must buy more. Go to the Roblox website, click the Robux icon in the top right, and select "Buy Robux." Roblox will show you different amounts you can purchase, ranging from 400 Robux to 40,000 Robux. The price in dollars varies depending on how many you buy at once.

You can pay with a credit card, debit card, gift card, or other payment methods depending on your region. After you complete the purchase, the Robux will appear in your account within a few minutes. Then you can go back to your account settings and change your username.

Age restrictions on username changes

If your account is for someone under 13 years old, you cannot change the username yourself. A parent or guardian must request the change through Roblox's parent controls or contact Roblox support directly. Roblox has this rule to protect younger players from making changes they might regret.

If you are 13 or older, you have full control over your username and can change it whenever the 30-day waiting period allows. Make sure you have access to the email address linked to your account, because Roblox may ask you to verify your identity before processing the change.

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. The timer starts when you confirm your new name, not when you first click the change button. You cannot pay extra to skip the wait.

What if someone takes my old username after I change it?

Roblox holds your old username for a period of time before releasing it publicly. Once it is released, anyone can claim it. You cannot reclaim it unless you wait for the person who took it to change their name or for their account to be deleted. Plan ahead if your old username is important to you.

Do I lose my Robux or items if I change my username?

No. Your Robux, game items, friends list, and everything else on your account stays exactly the same. Only the name changes. Your account history and past activity remain tied to your new username.

What if Roblox says my chosen name violates community standards?

Roblox blocks names that contain profanity, impersonate real people or brands, or break their rules. If your name is rejected, try a different one. You are not charged the 1,000 Robux if the name is rejected before you confirm the purchase.

Can I change my username if my account was created by a parent?

If you are 13 or older, you can change it yourself through your account settings. If you are under 13, your parent or guardian must make the change. Contact Roblox support or use the parent controls in your account settings to request help.
