Learn how to identify authentic e-mail from Discover

We're serious about helping you maintain the safety of your personal information. Here are some ways to help you identify authentic Discover e-mails:

Verify the Last 4 Digits of Your Account Number

The last four digits of your Discover card account appear at the top and bottom of every e-mail. Check to make sure the numbers match your account.

Check the Sender's Address

E-mails from Discover will come from one of these addresses:

discover@email.discover.com
service@email.discover.com
websupport@service.discovercard.com
discoverbusinesscard@email.discovercard.com
discover@service.discover.com

Help prevent spam and ensure safe delivery of legitimate e-mails by adding these addresses to your address book.

We're constantly working to improve e-mail security so you will also see this message in our e-mails:

E-mails to Be Cautious of:

Discover will never send you any e-mail that requests you to reply directly in an e-mail with any personal information such as:

Account numbers
Cardmember ID (CID)
Card expiration date
Account Center user ID or password
Birth date
Social security number

Any request for information regarding your account will require you to log in to your account which is protected by the secure firewall of Discover.com.
