Character length

Choose a username 6–30 characters long. Your username can be any combination of letters, numbers, or symbols.

Special characters

  • Usernames can contain letters (a-z), numbers (0-9), and periods (.).
  • Usernames cannot contain an ampersand (&), equals sign (=), underscore (_), apostrophe ('), dash (-), plus sign (+), comma (,), brackets (<,>), or more than one period (.) in a row.
  • Usernames can begin or end with non-alphanumeric characters except periods (.). Other than this rule, periods (dots) don’t matter in Gmail addresses.
