FedEx requires residential addresses with a house number only to be on the address line 1 WITH the street name. In the form of AddressLine1: HOUSENUMBER + STREETNAME.
Some integrations - such as Amazon allow the customer to have the house number as address line 1 and street name as address line 2.
This causes the packer to have to either edit the order address by inserting the street name into address line one OR the order cannot be fulfilled using FedEx due to the order lock on Amazon orders.
