Tips for a Good Username

1

Keep it short

Aim for under 12 characters so it's easy to read in chat.

2

Avoid just numbers

Instead of Name1234, try adding a prefix like its_Name.

3

Make it memorable

Use real words combined creatively rather than random letters.

4

Check for typos

Changing your username later costs 1,000 Robux!

5

Avoid copied formats

Originality stands out more than copying popular trends.

6

Think long term

Avoid dated memes that you might regret in a few years.
