The Basic Process: What Happens When You Change Your Name

You change your Roblox username through your account settings on the Roblox website — not in the game itself. The process takes about two minutes once you are logged in. Your new name appears when ready to other players, and your old name becomes available for someone else to use after a short waiting period.

One important thing to know: Roblox lets you change your username once every 30 days. If you changed it recently, you will see a countdown timer telling you when the next change is allowed. You cannot bypass this waiting period, and it applies whether you changed the name yourself or someone else changed it on your account.

The change costs Robux — Roblox's in-game currency that you buy with real money. The cost is 1,000 Robux, which is roughly $12.50 USD, though the exact dollar amount varies by country and payment method. If you do not have enough Robux in your account, you will need to purchase more before you can proceed.

Key Takeaways

  • You change your username in account settings on the Roblox website, not inside any game.
  • Each username change costs 1,000 Robux and you can only change once every 30 days.
  • Your old username becomes available for others to claim after a waiting period, so choose a name you plan to keep.
  • If your account was hacked and the name was changed without your permission, contact Roblox support with proof of ownership.

Step-by-Step: Changing Your Username on Desktop

Open a web browser and go to roblox.com. Log in to your account using your username and password. Once you are 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 that icon and select Settings from the dropdown menu. 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 — click that button.

A window will pop up showing your current username and asking you to enter a new one. Type the name you want into the text box. Roblox will tell you when ready if the name is already taken or if it breaks the naming rules — for example, names cannot contain certain words or be longer than 20 characters. Once you enter a name that is available, you will see the cost (1,000 Robux) and a button to confirm the change.

Click the confirmation button. If you have enough Robux, the change happens right away. Your new username is now live on your profile and in all games. If you do not have enough Robux, you will be taken to the Robux purchase page to buy more before you can complete the change.

Changing Your Username on Mobile

The process on a phone or tablet is almost identical, but the menu layout is slightly different. Open the Roblox app or go to roblox.com in your mobile browser. Log in and tap the three horizontal lines (hamburger menu) in the bottom right corner of the screen.

Tap Settings, then tap Account. Scroll down until you see the Username section. Tap Change Username and follow the same steps as on desktop — enter your new name, check that it is available, and confirm the purchase of 1,000 Robux.

What to Do If Your Username Was Changed Without Permission

If you log into your account and find that your username has been changed and you did not do it, your account may have been hacked. Change your password when ready by going to Settings > Account > Password and entering a new one. Then check your email address and phone number in the account settings to make sure they have not been changed as well.

After securing your account, contact Roblox support through their help page at roblox.com/support. Explain that your username was changed without your permission and provide details like the date you last logged in, the old username, and the new one. Roblox support can see the change history on your account and may be able to restore your old username if you can prove you own the account.

To prove ownership, be ready to provide information like the email address on the account, the date you created it, or any Robux purchase receipts. The faster you report it, the better — the longer a hacked account stays compromised, the harder it is to recover.

Choosing a Username You Will Not Regret

Because you can only change your username once every 30 days and each change costs Robux, it is worth thinking through your choice before you confirm. Your username is what other players see when you join games, so pick something you are comfortable with for at least the next month.

Avoid usernames that include your real name, birth year, or other personal information. Roblox is played by people of all ages, and keeping your identity private is safer. Also avoid names that are offensive or that you might be embarrassed by later — usernames that seemed funny at age 10 often do not feel the same way at age 15.

If you are not sure whether a name is available, you can type it into the change username box and Roblox will tell you when ready. There is no cost to check — you only pay the 1,000 Robux when you actually confirm the change.

Understanding the 30-Day Waiting Period

After you change your username, you cannot change it again for 30 days. This timer starts the moment you confirm the change, not when you first click the button. If you change your mind in the next 29 days, you will have to wait until the full 30 days have passed.

The 30-day rule applies to everyone, including accounts that were hacked and had their names changed by someone else. If your account was compromised and someone changed your username, you still have to wait 30 days from that change before you can change it again — unless Roblox support restores your old username, which resets the timer.

Frequently Asked Questions

Can I change my username for free?

No. Every username change costs 1,000 Robux, which you must purchase with real money. There is no way to change your username without spending Robux, and Roblox does not offer free username changes as part of any promotion or membership.

What happens to my old username after I change it?

Your old username becomes available for other players to claim after a waiting period. Roblox does not hold old usernames for you, so if you change your mind, you cannot get it back. Choose carefully before you confirm the change.

Can I change my username if I have not spent any money on Roblox?

Only if you have earned or received 1,000 Robux through other means. You must have 1,000 Robux in your account balance before you can change your username. If you have zero Robux, you will need to purchase some first.

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

Yes. Your friends list does not change, and they can still see you in their friends list under your new username. Games you have played and items you own stay with your account — only the name changes.

How do I know if a username is taken before I try to change to it?

Type it into the change username box on the account settings page. Roblox tells you when ready whether the name is available or already taken. You can check as many names as you want without paying anything — you only pay when you confirm a change.
