How shipping zones affect cost.

Zone drives the rate

Every additional zone adds cost for the same weight. Ship a lot of high-zone packages and your blended rate climbs accordingly.

Average zone is the metric

Total spend tracks closely with your average zone. Lowering it, even by a fraction, moves real money across thousands of shipments.

How to lower average zone

• Add or relocate a distribution center closer to demand.
• Split inventory across regions.
• Use zone skipping for dense lanes.
