Check your credit reports. Pulling your credit report and credit score is the most accurate and convenient way to find all of the accounts that have been reported in your name. Your credit report will display every open account in your name, from bank accounts to credit cards and more.

Go to http://accounts.google.com/signin/usernamerecovery and enter any email accounts or phone numbers that you've had for a while and which may have been used as recovery info. The “find your email” page can help you locate any forgotten Google accounts.

Your Google Account gives you a safe, central place to store your personal information — like credit cards, passwords, and contacts — so it's always available for you across the internet when you need it.
