  • What are the numbers on the back of my Discover Card?

    On the back of your Discover Card, there is an area where you sign your name. If your card was printed before July 2003, you will see two sets of numbers including your 16-digit Account number (see Card A) OR the last four digits of your Account number (see Card B). If your card was printed after July 2003, you will see three sets of numbers (see Card C or Card D).

    These numbers are part of the state-of-the-art technology that we employ to enhance security and cardmember convenience. The cardmember ID number is used to verify transactions made when the Card is not present, such as Internet or catalog purchases.

    It is also required when registering for the Account Center. The sequence number, which always begins with the letter "A," will be used for future product and security enhancements.

  • I requested a new card design, what should I do with my current card?

    Since your account number will not change, your current card will remain active until the expiration date. Continue using it until the expiration date shown on the card or call us at 1-800-DISCOVER (1-800-347-2683) to deactivate the card. You do not need to return your current card to us. If you choose not to use your old card, please destroy it.

  • I changed my reward program so why is my old card design still appearing on my account?

    If you recently changed reward programs, the card designs associated with the old rewards program will continue to be active until the expiration date shown on the card. You can continue to use that card for purchases until it expires and it will earn rewards towards the new reward program.

  • If I request a new card design, will my account number stay the same?

    Yes. If you request a new card design, the terms of your aggrement will remain the same, including your account number, interest rates, statement closing date, rewards program, and account center settings.
