Create a username

If you see "Username not allowed" when you sign up for your Google Account or Gmail, follow these guidelines.

Note: “Abuse” and “Postmaster” are reserved aliases, and you cannot use them as usernames or aliases. For more information, refer to our spam and abuse policy.

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.
