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

To create a new username on Roblox, log into your account, go to Settings, select the Account tab, and click Change Username. Type your new name, pay the fee (which varies by how many times you have changed it before), and confirm. The change takes effect when ready, though your old username becomes available for others to claim after 30 days.

The first username change is free. After that, each change costs 1,000 Robux — Roblox's in-game currency that you buy with real money. The cost does not increase with repeated changes; it stays at 1,000 Robux per change. You cannot change your username more than once every 30 days, even if you have the Robux to spend.

Key Takeaways

  • Your first username change is free, but every change after that costs 1,000 Robux, which you must purchase with real money.
  • You can only change your username once every 30 days, regardless of how much Robux you have.
  • The change happens right away, but your old username becomes available for others to use after 30 days.
  • You must be logged into your account and have access to your email to complete the change.

Step-by-step process to change your username

Start by going to the Roblox website and logging in with your email and password. Once you are on your home page, look for the gear icon in the top right corner and click it to open the menu. Select Settings from the dropdown.

In Settings, click the Account tab on the left side. Scroll down until you see the Change Username option. Click it, and a box will appear asking for your new username. Type the name you want, then click the Verify button next to it. Roblox will tell you right away if the name is taken or if it breaks the naming rules (no special characters, no spaces, between 3 and 20 characters long).

If your new name is available, you will see the cost displayed. Click Spend to confirm the purchase. If this is your first change, it will say Free. If you have changed your username before, it will show 1,000 Robux. After you confirm, the change takes effect when ready and you will be logged out. Log back in with your new username.

What happens to your old username

When you change your username, your old one does not disappear right away. For 30 days, only you can use it again if you change your mind. After 30 days, anyone else can claim it. This means if you had a username that other players knew you by, they will not be able to find you by that name after the 30-day window closes.

Your friends list and game history stay the same no matter what username you use. Other players who have you added as a friend will still see you in their friends list under your new name. Your Robux balance, game progress, and items do not change when you change your username.

Understanding Robux costs and payment

Robux is Roblox's virtual currency. To pay the 1,000 Robux fee for a username change, you need to have that amount in your account already. You cannot use real money directly for a username change — you must buy Robux first, then spend it.

Robux packages start at 400 Robux for about $5 USD and go up from there. Prices vary by country and payment method. You can buy Robux through the Roblox website using a credit card, debit card, PayPal, or gift cards. If you are under 13, your account may have restrictions on purchases, and a parent or guardian may need to approve the transaction.

Username rules and what you cannot use

Roblox usernames must be between 3 and 20 characters long and can only contain letters, numbers, and underscores. You cannot use spaces, hyphens, periods, or special characters like @, #, or $. Usernames are not case-sensitive, so "MyName" and "myname" are treated as the same username.

Roblox blocks usernames that contain profanity, slurs, or references to real people's names without permission. If you try to use a name that violates these rules, the system will reject it and tell you the name is unavailable. You will need to choose a different name and try again.

What to do if you cannot change your username

If you see a message saying you cannot change your username, the most common reason is that you have already changed it within the last 30 days. You must wait until the 30-day period is over before you can change it again. Check your account settings to see when your last change was made.

If you do not have enough Robux and your change is not free, you will need to buy more Robux before you can proceed. If the username you want is taken, try adding numbers or an underscore to make it unique. If you believe your account has been hacked or locked, contact Roblox Support through the Help page on their website.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but only within 30 days of changing it. After 30 days, your old username becomes available for anyone to claim, and you would have to pay 1,000 Robux to use it again if someone else has not already taken it. If someone else claims it first, you cannot get it back.

Do I lose my games or items when I change my username?

No. Your Robux, game progress, inventory, and friends list all stay exactly the same. Changing your username is purely cosmetic — it only changes what other players see when they look at your profile or encounter you in games.

What if the username I want is already taken?

Try adding numbers or an underscore to make it unique, like "username_1" or "username123". You can also check if the name belongs to an inactive account by visiting their profile, though Roblox does not reserve old usernames for inactive players. If you really want a specific name, you may have to wait and check back periodically.

Can a parent or guardian change a child's username?

Only the account holder can change the username through their own Settings. If a child's account has parental controls enabled, the parent can manage some settings, but username changes must be done by the child logging in themselves. Parents can set spending limits on Robux purchases.

Is there a way to change my username for free after the first time?

No. After your first free change, every subsequent change costs 1,000 Robux. Roblox does not offer free username changes beyond the initial one, and there is no way around the cost or the 30-day waiting period between changes.
