I cannot successfully update my payment method on my Apple ID

When a card is being placed on file for future purchases, Apple will verify that the account is active and verify basic information like address, activity on account etc. Either your bank or the payment network (Mastercard, Visa etc.) is not able to verify the card.

You’ll need to contact Apple Support for assistance with the issue. If you’re in the US please call  1-800-MY-APPLE or outside the US, consult the support articles below.

Where does it fail? Sometimes all you need to do is reset the expiration data and the CVV security code. Is there any information in read stating what the error is? If so, please share that information.
