You can change your Roblox username through your account settings, but the process has limits you should know before you start

To change your username in Roblox, go to your account settings, find the "Change Username" option, enter your new name, and confirm the change. The whole process takes about two minutes. However, Roblox limits how often you can change your username and charges Robux (the in-game currency) for each change after your first one.

Your first username change is free. After that, each change costs 1,000 Robux, which is roughly $12.50 USD depending on your region and current exchange rates. You can only change your username once every 30 days, so plan your new name carefully before you start.

Key Takeaways

  • Your first username change is free, but every change after that costs 1,000 Robux.
  • You must wait 30 days between username changes, so you cannot change it back when ready if you regret your choice.
  • Usernames must be between 3 and 20 characters long and cannot contain spaces or special characters.
  • Your old username becomes available for other players to claim after you change it, so do not expect to reclaim it later.

Step-by-step: changing your username

Log into your Roblox account on a computer or mobile device. Go to the settings menu by clicking the gear icon in the top right corner of the page (on mobile, tap the three horizontal lines, then tap "Settings").

Click or tap "Account" in the left sidebar. Scroll down until you see "Change Username" and click or tap it. Type your new username in the text box that appears. Roblox will tell you when ready if the name is already taken or breaks the naming rules.

Review the cost. If this is not your first change, you will see the 1,000 Robux charge displayed. Click or tap "Buy" to confirm and complete the change. Your new username takes effect right away.

What usernames Roblox will and will not allow

Roblox usernames must be between 3 and 20 characters long. They can contain letters (uppercase and lowercase), numbers, and underscores only. Spaces, hyphens, periods, and special characters like @, #, or $ are not allowed.

Roblox also blocks usernames that contain profanity, slurs, or references to drugs and alcohol. The system checks your name automatically when you type it, so you will see an error message if your choice violates the rules. If you are unsure whether a name will work, try typing it in the change username box — Roblox will tell you before you pay anything.

Usernames that impersonate Roblox staff, famous people, or other well-known players may be flagged and changed by Roblox moderators, even after you have set them. If this happens, you get a free username change to pick something new.

The 30-day waiting period between changes

After you change your username, you cannot change it again for 30 days. This rule applies to everyone, including users who paid Robux for their last change. The 30-day timer starts the moment your new username takes effect, not when you click the button.

If you try to change your username before 30 days have passed, the "Change Username" option will be grayed out and show you how many days you have left to wait. There is no way to speed this up or pay extra to change it sooner.

What happens to your old username

When you change your username, your old one becomes available for any other player to claim. You cannot reserve it or ask Roblox to hold it for you. If you change your mind and want your old name back, you will have to wait until 30 days have passed, then pay 1,000 Robux to change to it — but only if no one else has claimed it in the meantime.

Your friends will still be able to find you after you change your username. Roblox keeps your account ID the same, so your profile, games, and friend list do not change. The only thing that changes is the name that appears next to your avatar.

If you cannot afford the Robux cost

If you do not have 1,000 Robux and do not want to buy them, you can earn Robux through Roblox games that reward them. However, earning enough Robux this way takes time and is not may provide. Some games offer small amounts of Robux for completing tasks or reaching milestones, but the amounts are usually small.

Another option is to ask a parent or trusted adult to buy Robux for you if you are under 18. Robux can be purchased through the Roblox website or mobile app using a credit card, debit card, or gift card. A 1,000 Robux package costs around $12.50 USD, though prices vary by region.
