There are a number of reasons why a credit card may be declined:
- Your bank declines the payment based on your spending habits, account balance, or card information like the expiration date and CVC.
- Your payment is blocked because it was identified as high-risk.
Double check that you entered your credit card details correctly (card number, expiration month and year and CVC) and also that all of the details on the payment form are filled out. If your card is still declined, try a new card or contact your credit card company by calling the customer service number on the back of your card.
