Postal zones are based on the distance that a mail piece travels from origination to destination. These distances are formulated into zones, which are seen on the USPS zone chart. Since zones are calculated based on where you are mailing from, make sure you use a USPS zone chart that is specific to your originating ZIP code.
The first 3 digits (prefix) of your destination ZIP code determine the shipping zone for your mail piece. Find the ZIP prefix within the ZIP code range of your destination and you will find the postal zone for your mailing in the same row.
Example: To send a package from ZIP code 38012 to ZIP code 06484:
- Use this sample chart (created based on the originating (380) ZIP code prefix.)
- Find the prefix for the destination ZIP code 06484
- The prefix for 06484 (064) falls within the 010 - 065 range.
- Your mail piece should go to zone 6.
Eight United States Postal Service (USPS) Zones measure the distance from a mailer's location to the receiver's location. The mailer's local ZIP code is always the starting point. As shown below, zones increase from one (1) through eight (8) as the mailing address gets farther away. The zones are used to gauge postage for the USPS.
Entering the Correct Zone for Your Mail
Below are instructions on how to obtain a Zone and enter it on your meter.
- If the class of mail requires a ZIP Code or Zone to be entered, your system will prompt you to enter one.
- Go to the USPS Zone Chart and enter the first three digits of your ZIP code to get your updated Zone chart.
- Find the destination ZIP Code (the first three digits of the ZIP Code you are mailing to) on the chart in order to determine the Zone.
- Enter the single digit Zone (1-8) you found on the chart into your meter when prompted for a ZIP Code or Zone.
