Roblox Username Rules
- 3–20 characters.
- Letters and numbers, plus at most one underscore that is not first or last.
- No spaces, periods or other symbols.
- No inappropriate words or personal information.
- Changing the username later costs 1,000 Robux; the display name is the cheaper way to rebrand.
Safe Usernames for Kids
Roblox is popular with younger players, so it's worth choosing a name that keeps personal details private. Leave out real names, ages, school names, birth years and locations. A fun word pair like MochiBunny or TurboTitan is just as memorable and much safer. Roblox's parental controls are covered in its official help pages.
