Postal ZIP Zones and Zone Charts

UPDATED: December 28, 2017

Postal Zones are based on the distance a mail piece travels from origination to the destination. These distances create specific Zones, seen on a United States Postal Service (USPS®) zone chart.

TIP: the first 3-digits of your destination ZIP Code determine the Zone, or 'prefix'. For example, the prefix for ZIP Code 67679 is 676.

Get Zone Chart - online tool
Enter the first 3-digits into the field and select Submit. 

* Indicates ZIP Code range within the same NDC as the origin ZIP Code
+ Indicates ZIP Code range has 5-Digit Exceptions

In the chart onscreen, 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.

Entering the Correct Zone for Your Mail
Follow these instructions to obtain a Zone to enter on your meter:

  1. If the class of mail requires a ZIP Code or Zone to be entered, your system will prompt you to enter one.
  2. Go to USPS Postal Zone Charts and enter the first three digits of your ZIP code to get your updated Zone chart.
  3. 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.
  4. Enter the single digit Zone (1-8) you found on the chart into your meter when prompted for a ZIP Code or Zone.

IMPORTANT: USPS Rate Changes can include ZIP and Zone changes. On some meters the Zip Code entry includes both numbers and letters; meters include: DM100i®--DM225™, mailstation™ and mailstation2™.

About Zones
Eight 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 in the following graphic, zones increase from one (1) through eight (8) as the mailing address gets farther away. The zones are used to gage postage for the USPS.
