Need to update credit card number

Hi, I would try this page in the Apple help

https://support.apple.com/en-us/HT201266

It will help you get your information up to date.

See Set up your Apple ID payment method and shipping address on Mac https://support.apple.com/guide/mac-help/set-apple-payment-method-shipping-address-mac-mchl29cac995/mac

And on an iPhone, use Settings > Name/Apple ID > Payment & Shipping

_______

And see Change, add, or remove Apple ID payment methods https://support.apple.com/en-us/HT201266
