Roblox username rules in short

A Roblox username must be 3 to 20 characters long. It can use letters and numbers, plus one underscore that cannot be the first or last character. Spaces and other symbols, including dots, are not allowed. Roblox also filters personal information and inappropriate words, and usernames are unique, so a name you like may already be taken.

Tips for picking a Roblox username

  • Keep it short and easy to read. Friends need to be able to type it and say it out loud.
  • Pick something you will still like in a year, not just this week’s joke.
  • Never use your real name, age, school, address or social media handles in a username.
  • Skip long strings of numbers. One or two digits are enough to make a name unique.
  • Use CamelCase if you want a long name to stay readable, such as BrickBuilder instead of brickbuilder.
  • If a name is taken, add your own word in the box above and generate again.

Username and display name

Roblox gives you two names. Your username is unique and has to follow the rules above. Your display name is what many players see first, and it does not have to be unique, so it is the place to show more personality.

NameWhat it is
UsernameYour unique account name. Letters, numbers and one underscore, 3 to 20 characters.
Display nameA name shown to other players that can be shared with others. It is more flexible than a username.

A simple approach is a clean, short username from this generator and a display name with extra flair.
