What Addresses Fall Into the "PO Box" Shipping Zone?

Overview

The PO Box Shipping Zone in ShipperHQ is triggered based on patterns detected in the street address line, not by a specific carrier or shipping method alone. When an address matches known PO Box formats and the destination country is the United States, ShipperHQ applies the PO Box zone and any associated rules or functionality.

An address is classified into the PO Box Shipping Zone when both of the following conditions are met:
