If you can't add a payment method, check Add a payment method to your Apple Account - Apple Support , or this one about what to do if your payment method is declined in the App Store or iTunes Store —> If your payment method is declined in the App Store or iTunes Store - Apple Support
- Apple is checking with your financial institution if the payment method is valid and receiving a negative, or no, response. Make sure the name and address are entered exactly as it appears on your financial institution bills and that the 3 digit CVV is correct. Check with your financial institution about the status of your card. “If you want to know why a debit card, credit card, or other payment method was declined, speak with your financial institution. Apple doesn't have information about why the payment method was declined.”
- Make sure your payment method is up to date or to try a different one ( If you need to change or update your Apple Account payment method - Apple Support ).
- Make sure this is one of the payment methods that you can use with your account, as listed in this support article: Payment methods that you can use with your Apple Account - Apple Support .
・Unfortunately the payment methods list is somewhat general and does not include individual brands of cards (I guess there are too many and are constantly changing). This thread is an example of where a person was not using an acceptable kind —> Why are my cards not supported on the MFI… - Apple Community
・Also read any footnotes in the document.
・If you are trying to use a payment method from another country you may encounter problems. Apple’s statements to me are unclear. In If your payment method is declined in the App Store or iTunes Store - Apple Support Apple implies international payment types can be used when it says, "You might need to ask your financial institution to allow international purchases on your debit or credit card". Apple then counters this in Add a payment method to your Apple Account - Apple Support with, “If you're using an accepted payment method but your Apple Account is set to a different country or region, change your country or region.” Usually it is easiest to just use a card from the same country as your Apple Account setting.
・Finally, note that the document only says which methods _are_ acceptable. Apparently certain types (usually a credit or debit card) _must_ also be present under certain situations such as when a subscription is involved.
