Hello, I cannot change billing address and my payment method not acceptable for my current region

- Apple is checking with your financial institution if the payment method is valid and receiving a negative 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.

- Make sure your payment method is up to date or to try a different one ( If you need to change or update your Apple ID 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 ID - Apple Support . A solution may also be to use a method from the same country as the store you are using. It is frequently posted here that this is a requirement but the only official statement I can find about international payment methods is what Apple itself says is in its own support article specifically helping you with declined payment methods: https://support.apple.com/HT203005 I quote it here for you and others to read. "You might need to ask your financial institution to allow international purchases on your debit or credit card".

・Unfortunately the payment methods list is somewhat general and does include individual brands of cards (I guess there are too many and are constantly changing).

・Also read any footnotes in the document.

・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.

If you still have problems, contact official Apple Support. Click here --> Choose your country or region - Official Apple Support Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
