USPS uses the term "zones" to describe the distance a domestic shipment must travel.
Zones range from Zone 1 (local) to Zone 9 (very far away). A zone is determined by the "ship from" zipcode 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.
The first 3 digits of your destination ZIP Code determine the zone. If you are shipping local (Zone 1) the package is not traveling very far. If you are shipping non-local (Zones 2-9), the zone is determined by how many zones a package crosses to arrive at the destination. You can look up the zone for your shipment using the USPS Zone lookup tool.
You are shipping a 4lb. package from New Orleans, 70117, to Nashville, 37202.
Using the USPS Zone lookup tool, enter in the first 3-digits of your zip code and then Select.
On the results chart, locate the first 3-digits of the destination zip code to find the zone (4).
Now, you can look at the rate table to locate the price by finding there the weight and the zone marry. For this example, we use the Priority Mail - USPS Commercial | Rate Table.
The cost of the label is $9.47.
Zones only apply to USPS domestic services. If a service is selected that relies on weight or dimensions to determine the rate, then the zone will also factor into the postage cost. View ShippingEasy's USPS Rate Tables for your plan.
