When you request a rate in the ShipEngine API, you might get a value back for “zone” in the response. USPS uses Postal Zones to estimate the distance between an origin and destination address. These zones are numbered from 1-9; Zone 1 is a local shipment, and Zone 9 is the furthest possible distance between locations for a domestic shipment.
