Zip Zone Changes
Effective Date: October 1, 2019
Mandatory Implementation Date: November 1, 2019

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)
