Account Questions

Do not activate the card. Contact Capital One immediately by calling the fraud reporting line at 1-800-227-4825 (available 24/7) to report the situation. It’s possible the card was sent in error or your identity may have been used without your permission. Capital One’s fraud team will investigate and advise you on next steps. See the Contact Support page for all contact options.

​
After Activation Questions

Your card is active immediately after completing the activation process. You can start making purchases right away.
Activating a replacement card works the same way as activating a new card. Visit capitalone.com/activate, sign in, and select the replacement card from your account. Verify your information and click Activate. Your old card will be automatically deactivated once the replacement is active. For full details, see the How to Activate guide.
Yes. After activation, you can add your card to Apple Pay, Google Pay, or Samsung Pay from your phone’s wallet app.
Wait 15 to 30 minutes after activation and try again. If it’s still declined, check that your billing address is correct in your account, verify you’re using the right PIN for debit cards, or call the number on the back of your card.
Your old card is automatically deactivated when you activate a replacement card. Cut up and dispose of the old card securely.
