How I change my App Store country region and add the card ?

Hi wayme16,

Thanks for reaching out to Apple Support Communities. We understand you're either changing or have changed your Apple ID region and want to add a payment card. We'll be happy to assist.

You'll need to use a card from the same country/region as your Apple ID. The resource you came to us from has the details. If you've already changed your region and are using a card from that same region, these steps may help with adding a payment method: Change, add, or remove Apple ID payment methods. We hope this helps.

Best regards.
