Zip Zone Changes

From time to time, the USPS will make changes to ZIP Codes and Zones. It is important that you update your meter whenever there is a change.

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)
