Why would my customer get an error of “Address does not match” when they use a credit card to checkout through Authorize.Net on my Storefront?

Authorize.Net requires that the address detail used in the storefront match the address your customer has attached to their credit card account. Authorize.Net payment method does not ignore address mismatches. This is for the security of your customers card. Advise your customers to check the billing address, a business name or any other field that has information that is may not be matching.
