How do I change the card number I pay with

Hi 5464OTN-bush

welcome to the Apple (user-to-user) Community!

Your Apple ID is the account that you use to access all Apple services and make all of your devices work together seamlessly.

To change the card number you are using in your Apple ID account for iCloud payments, you may need to add a new card first, before you can delete the old one.

How to add an Apple ID payment method:

Add a payment method to your Apple ID - Apple Support

How to delete an Apple ID payment method:

Remove a payment method from your Apple ID - Apple Support

How to change an Apple ID payment method:

If you need to change or update your Apple ID payment method – Apple Support

All the best :-)

Add, then Trash:

You need at least on method of payment in there. So, add the new number, and then trash the one that is currently in there..
