## Discussion

See <doc://com.apple.documentation/documentation/Contacts/CNPostalAddress> for the values that can be used with this key. These values point to the specific area of the address that is at fault, for example, <doc://com.apple.documentation/documentation/Contacts/CNPostalAddressStreetKey> indicates the street. When you supply the key values in a payment error, the Apple Pay sheet highlights the appropriate field, enabling the user to correct errors.
