Choosing a Roblox Username

Your Roblox username identifies your account, so it is worth choosing carefully. Roblox Support documents a 3 to 20 character format using letters, numbers, and up to one underscore that is not at the beginning or end. Roblox also filters inappropriate names, so clean, readable handles are the safest bet.

Because Roblox has hundreds of millions of accounts, many simple names are already taken. A reliable trick is to combine two words plus a short number, or swap in an underscore — for example PixelFox_7 or NovaBuilderX. Generate a batch above and try them in order on the signup screen until one is free.

How to Change Your Roblox Username

Two names, two different rules. Changing your username — your account identifier — costs Robux every time. Changing your display name, which is what other players actually see in experiences, is free. If you only want a different name on screen, change the display name and leave the username alone.

Changing the username

  1. Log into your account.
  2. Open Settings — the gear icon (top-right) on a browser, or the three-dots More menu in the mobile app.
  3. Select the Account Info tab.
  4. Select the Change Username button (pencil icon).
  5. Enter your new username, then your current Roblox password.
  6. Select Buy to confirm the change.

A few things worth knowing before you buy: your account’s original creation date carries over to the new name, your previous usernames stay visible to other players through People search, and you can switch back to an old username later — though that also costs Robux. You can’t take a name that belongs to another account, and there is no discount for a cosmetic tweak like changing capitalisation.

Frequently Asked Questions

What are the Roblox username rules?

A Roblox username must be 3 to 20 characters. It can contain letters and numbers and at most one underscore, and the underscore cannot be at the start or the end. Spaces and other symbols are not allowed, and offensive names are blocked by Roblox's filter. Our generator keeps every idea inside these limits.

What is the difference between a Roblox username and a display name?

Roblox usernames identify an account, while display names are shown separately in the Roblox experience. Their rules and change options differ, so use Roblox account settings for the current display-name behavior and keep the username itself clean and distinctive.

How do I change my Roblox username?

Log in, open Settings (the gear icon on a browser or the three-dots More menu in the app), select the Account Info tab, then the Change Username button. Enter your new username and current password, and select Buy to confirm. If you only want a different on-screen name, change your display name instead — that is free.

How much does it cost to change a Roblox username?

Every username change costs Robux, and switching back to a previous username costs Robux too — there is no discount for a small change like adjusting capitalisation. Your display name, by contrast, can be changed for free. Roblox shows the current price in the change flow before you confirm.

Can I use symbols or fancy fonts in my Roblox name?

This generator uses the documented username format: letters and numbers with at most one underscore that is not first or last. Display names are a separate Roblox feature with different moderation behavior; use the official Roblox settings for the final check.

How do I find an available Roblox username?

This tool generates rule-valid ideas locally; it does not check Roblox availability. Enter a name on the Roblox signup or account settings screen to see instantly whether it is free. Generating a batch of ten and trying them in order is the fastest way to land one that is open.
