Change exp date and code on credit card on file
How do I change the pin and date of expiration date on my credit card that I use for Apple charges?
You may have to add it as a new card and promote it to be the primary payment method.
Log into your account in the App Store/iTunes and you should be able to change/verify it there. Or you can click the blue Edit payment methods in the article below. When signed in and the page loads, you will be on the credit card page. If you have a subscription, you need to add the new card, and then promote it to the primary payment method before you can remove the old card.
