What is a Zone?

Created:   |   Updated:

Zones are a tool used by USPS to measure the actual distance a package must travel. Zones range from Zone 1 (local) to Zone 9 (very far away). A zone is determined by the "ship from" zip code as it relates to the "ship to" zip code. The farther a package must travel, the more zones it crosses, and the more it costs to ship it.

If a weight- or dimensional-based service is selected, then the zone will factor into the overall cost of the service.
