The fastest and most convenient way to activate your new card is through the Barclays app or on our website.

1. Install and launch the Barclays US Credit Card app on your mobile device, or visit the activation page of our website. (If you don’t have the Barclays App download it on Apple's App Store or on Google Play.)
2. If you already have an online account — Choose “Existing Cardmember” and log in using your username and password. Verify your identity by completing the required fields. Your card will be activated and ready for use.
3. If you’re a new Cardmember or don’t have online account access set up — Select “Activate my card now” and complete the required fields.
4. Select “Continue” and your new card will immediately be activated and ready to use.
