The USPS( United States Postal Service) covers every square mile of the U.S. Since January 2019, zone-based pricing has applied to all USPS package classes that are not flat-rate. Zone charts are produced by the United States Postal Service using geological latitude and longitude coordinates to determine the distance between origin and destination ZIP Code pairings. Zone charts are updated every quarter.

USPS Zones Explained

Zones play a significant role in the delivery of goods and services. USPS shipping zone charts focus on the postage price depending on the residential area and the speed of delivery. The National Zone Charts Matrix assists shippers in applying accurate postage rates to mail a package. Postage rates for mail are based on weight and the distance the mail piece travels using zone charts.

Zones differ accordingly; different cities, different maps. For example, if you are in Chicago and your sister is in New York, the map of the United States postal zone in Chicago would differ from that of your sister.

The USPS has approximately nine shipping zones, eight in the continental U.S. Lastly, zone 9 is left out for outlying territories, predominantly islands.

  • Zone 3: 151- 300 miles
  • Zone 4: 301-600 miles
  • Zone 5: 601-1000 miles
  • Zone 6: 1001- 1400 miles
  • Zone 7: 1401- 1800 miles
