- 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)
Important: These are USPS resources. For questions or assistance, contact the USPS or your local Post Office.
