What is a Secure Online Account Number?
Secure Online Account Numbers is a free service that offers you added security by protecting your account number while shopping online, and the convenience of automatically filling online checkout forms. By using a secure number in place of your actual Discover Card account number, your actual account number is not revealed on the Internet or stored in an online retailer’s files. If they don’t have your number, it can’t be lost or stolen. Because a secure number can only be used at the store where it was first assigned, if it is ever lost or stolen, it can’t be used anywhere else.
