To activate a Discover card, use the online activation page or call Discover customer service at 1 (800) 347-2683. Discover card activation requires a Social Security number as well as the card number, expiration date and security code.
You don’t need a Discover username and password to activate a Discover card online. But having an account can streamline the process because you won’t have to enter extra personal information to verify your identity. Either way, Discover card activation is quick and easy. Plus, the steps are the same for Discover credit cards and debit cards.
How to activate a Discover card:
- Go to the Discover card activation page.
- Log in to your account or choose “Without Logging In” if you don’t have one.
- Enter your birthdate, the last 4 digits of your SSN, your 16-digit card number and the card’s expiration date. (Only needed if you don’t log in)
- Type in the 3-digit security code from the back of the card.
- Click “Continue” to activate your Discover card.
You can use a Discover card immediately after activation. For security reasons, you cannot make any transactions with a Discover card before activating it. Activation ensures that someone doesn’t steal the card out of the mail and use it.
To activate a Discover gift card, use the online activation page or call 1 (866) 522-7026.
