Roblox Username Checker
Type the name you want. We ask Roblox whether it is free, already taken, or not allowed.
What the answer means
Available means you can register or switch to the name today, though someone could still grab it before you do. Taken means another account has it. Not allowed means Roblox blocks it for its own rules, for example names that look like personal details.
Rules for Roblox usernames
- 3 to 20 characters
- Letters, numbers and one underscore only
- No spaces and no underscore at the start or end
- No phone numbers, emails or other private info
Short and simple names are the hardest to find. Adding a number or a second word usually works.
Questions
Does checking a name reserve it?
No. Register or change your name on Roblox to actually claim it.
Can I take a name that used to belong to someone?
If the name shows as available, yes. Roblox frees names when an account changes its username.
