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.
Endicia provides a dynamic map illustrating zones across the country based on your zip code. Go to Endicia's zone map.
USPS provides a detailed breakdown of zones based on specific sets of zip codes. Go to USPS' look up tool.
If a weight- or dimensional-based service is selected, then the zone will factor into the overall cost of the service.
