On a VISA, MasterCard, and Discover please turn your card over and look in the signature strip. You will find (either the entire 16-digit string of your card number, OR just the last 4 digits), followed by a space, followed by a 3-digit number. That 3-digit number is your Securty Code. On American Express Cards, the Security Code is a 4-digit number that appears above the end of your card number.
