You can change your Roblox username through your account settings, but the process has limits on how often you can do it

To change your Roblox username, log into your account on the Roblox website, go to Settings, click the Account tab, and look for the Username field. Click the change button next to your current name, type your new username, and confirm the change. The new name takes effect when ready.

Roblox allows one free username change every 30 days. After that, each additional change costs 1,000 Robux — the in-game currency you buy with real money. If you have never changed your username before, your first change is always free, regardless of when you created your account.

Key Takeaways

  • Username changes happen in Settings under the Account tab on the Roblox website, not in the mobile app.
  • You get one free change every 30 days; additional changes cost 1,000 Robux each.
  • Your new username must be between 3 and 20 characters and cannot contain spaces or special characters.
  • Roblox reserves certain usernames and will reject names that violate community standards, so you may need to try several options.
  • Changing your username does not affect your account data, game progress, or items — only the name other players see.

Step-by-step process on desktop

Open a web browser and go to roblox.com. Log in with your email and password. In the top right corner, click the gear icon or your profile picture, then select Settings from the dropdown menu.

On the Settings page, click the Account tab on the left side. Scroll down until you see the Username section. Click the button labeled "Change Username" or the pencil icon next to your current name. A text box will appear where you can type your new username. Type your desired name, then click the Verify button to check if it is available. If Roblox approves it, click the Confirm button to save the change.

The change takes effect right away. Other players will see your new username in games and on your profile within seconds. Your old username becomes available for other players to claim after a short delay.

Username rules and what Roblox will reject

Your new username must be between 3 and 20 characters long. It can contain letters (uppercase and lowercase), numbers, and underscores only — no spaces, hyphens, periods, or other symbols. Roblox will tell you when ready if your choice breaks these rules.

Roblox also blocks usernames that contain profanity, slurs, or references to real people's names without permission. The system flags names that look like they belong to Roblox staff or famous players. Some common words are reserved and cannot be claimed. If your first choice is rejected, try adding a number at the end or using an underscore between words.

The cost and timing of multiple changes

Your first username change is free. After that, you can change your username once every 30 days for free. If you want to change it again before 30 days have passed, or if you have already used your free monthly change, you must pay 1,000 Robux.

Robux is purchased with real money through the Roblox website or app. The price varies slightly by region, but 1,000 Robux typically costs around $10 USD. Roblox does not refund Robux spent on username changes, so choose carefully before paying.

The 30-day timer resets from the date of your last change, not on a calendar date. If you changed your username on March 15, your next free change becomes available on April 15.

What does not change when you change your username

Your account ID, game progress, Robux balance, and inventory all stay exactly the same. Friends will still see you as a friend, and you will still have access to all games, items, and achievements you owned before the change. Your profile page updates to show your new name, but your account history and statistics remain linked to your account.

If you are part of a group or clan in a game, your membership does not disappear. Other players may need a moment to recognize you by your new name, but the game servers know who you are by your account ID, not your username.

Changing your username on mobile

The Roblox mobile app does not have a built-in username change feature. To change your username on a phone or tablet, open a mobile web browser, go to roblox.com, and follow the same steps as the desktop process. You can also use the "Request Desktop Site" option in your browser settings to access the full website version on mobile.

Some players report that the mobile browser version is slower or occasionally glitchy. If you run into problems, try a different browser or wait a few minutes before trying again. The desktop website is the most reliable way to change your username.

Frequently Asked Questions

Can I change my username back to my old one?

Yes, but only if no one else has claimed it. Old usernames become available after a delay, so if you change back quickly, you may be able to reclaim it. If someone else has taken it, you cannot use it again unless they change their username first.

What if I see an error message when I try to change my username?

Common errors include "Username unavailable" (someone else has it or it is reserved), "Invalid username" (it breaks the character rules), or "Too many attempts" (you tried too many names in a short time). Wait a few minutes and try again. If the error persists, log out, clear your browser cache, and log back in.

Do I have to pay Robux if I change my username within 30 days?

Yes, unless it is your first change ever. You get one free change every 30 days. Any change before the 30 days are up costs 1,000 Robux. The timer resets from your last change date, not from a calendar date.

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

Yes. Your account ID does not change, so your friends list and group memberships stay the same. They will see your new username in their friends list and in games. You will still receive messages and join requests as normal.

Can I change my username if my account is banned or suspended?

No. You cannot access account settings or make any changes while your account is under suspension or ban. You must resolve the issue with Roblox support first. Contact them through the Roblox website's support page to appeal or learn why your account was restricted.
