If you’ve forgotten your username, you can test possible email addresses on our account recovery page. Unless you previously added an alternate email address to your account, we won’t be able to email you your account username for security reasons. To ensure you receive important notifications from us, please add address to your address book.

For Gmail users who provided an alternate email address when signing up for Gmail, here's how to recover you username:

  1. Visit the username-assistance page.
  2. Enter your alternate email address and click Submit.
  3. Type the pictured characters and click Submit.
  4. Check your alternate email account for a list of Gmail usernames you've associated with the address.
    • If you received an email from the Gmail team at your alternate address after signing up, you can also retrieve your username from that message. Keep in mind that we won't be able to help you recover your username unless you can access your alternate email address.
    • If you didn't provide an alternate email address when you signed up for Gmail but received an invitation to sign up, you may be able to retrieve your username by clicking the link in your Gmail invitation.

Visit the Gmail Help Center for additional username recovery tips. You may also recover your password.
