  • How do I tell which browser I'm using?

    You can tell what browser you are using by:

    • Clicking on the "Help" button on your browser's tool bar
    • Clicking on "About" for the browser and the version will display in that window
  • Why do I get logged off for inactivity after only a brief time?

    Because of security measures, you are logged off due to inactivity so no one can  steal your information.
  • What security measures are in place on Discover.com?

    We have multiple industry-standard security solutions in place such as 128-bit Secure Socket Layer (SSL), which encodes personal information you send over the Internet. We also employ multiple firewall layers and active system monitoring to provide real-time fraud alerts.
  • How can I tell if an email is really from Discover card?

    Authentic e-mails from Discover will come from one of these five addresses:

    If you receive what appears to be a fraudulent email from us, please email us at emailwatch@discover.com or call 1-800-DISCOVER (1-800-347-2683) immediately.

  • What if I receive an error message that states, "You have exceeded the maximum number of unsuccessful registration attempts?"

    We limit the number of unsuccessful registration attempts that can occur in one day to protect the security of your Discover Card account. If you receive this message, you will be unable to re-register until the following day. If you need immediate access, you can contact Customer Service at 1-800-Discover (1-800-347-2683).
  • What if I get a message that states, "The User ID you have selected is already in use" while I am registering for the Account Center?

    This message indicates that someone else has already chosen the user ID you wish to use and you must select something else.
  • What if I receive an error message that states, "You have exceeded the maximum number of unsuccessful sign-in attempts?"

    We limit the number of unsuccessful sign-in attempts that can occur in one day to help protect the security of your account.

If you need immediate assistance, please contact Customer Service at 1-800-DISCOVER (1-800-347-2683) and ask for a password reset.
  • What if I get an error that states, "Page Cannot be Displayed"?
