  1. Find postage rates for your mail piece on the USPS Price List when using Zone Charts.

The USPS® Zone Charts Matrix helps you apply the proper postage rates to a mail piece.  

Postage rates for zoned mail are calculated based on:
  • mail piece weight and
  • the distance the mail piece travels  

The matrix determines the distance a mail piece travels based on the first three digits of:

  • the ZIP Code™ you are mailing from (origination) and
  • the ZIP Code you are mailing to (destination)
