USPS rates will increase on July 12, 2026, if approved by the Postal Regulatory Commission.

(As of 5/27/26, all changes have been approved except Priority Mail Express, Priority Mail, Ground Advantage and Parcel Select, which are still pending.)

The charts below show the rates in effect until July 11, 2026 (in black and white) and new rates effective July 12 (highlighted).

Presort & commercial rate changes:

There are no rate changes for 7/12/26. The rates effective 4/26/26 remain in effect.

However, due to a change in the way dimensional weight is calculated, some pieces larger than one cubic foot that were charged based entirely on weight will now be charged based on dimensions.

Here are the rates for the first ten pounds. You can find the zones for any zip code using the USPS Domestic Zone Chart page.

Since Area Distribution Centers (ADCs) have been merged into SCFs, all ADC rates have been discontinued in favor of the lower 3-digit rates.

Since Area Distribution Centers (ADCs) have been merged into SCFs, all ADC rates have been discontinued in favor of the lower 3-digit rates.

Effective 7/12/26, the per-bundle and per-container charges that were applied to outside county pieces are discountinued. Those costs are rolled into increased outside county piece rates.

Since Area Distribution Centers (ADCs) have been merged into SCFs, all DADC rates have been discontinued in favor of the lower DSCF rates.

Presorted rates will now be calculated by rounding up to the next full pound, instead of being calculated using each piece's exact weight.

Meanwhile, as part of its proposal to eliminate Bound Printed Matter (BPM), USPS proposed a new category of Marketing Mail that looks very much like BPM, but can't be used for fulfillment. Even though BPM still exists, USPS will introduce Marketing Mail Heavy Printed Matter effective July 12 along with the postal rate increase.

In the new rates, Heavy Printed Matter will cost slightly less than the increased rates for Bound Printed Matter parcels, but higher than Bound Printed Matter flats.

We're preparing a chart comparing the two services and will post it here as soon as the final rules for Heavy Printed Matter are issued.

Our Postage Saver for Parcels software will support Heavy Printed Matter rates when they become active on July 12, 2026, and will continue to support Bound Printed Matter rates.

Here are the rates for Bound Printed Matter:

Media Mail and Library Mail rates are going down slightly.

How to calculate volume

To determine whether a parcel is more than 2 cubic feet in volume, meaning that the USPS volume surcharge will apply:

• Measure the length, width and height in inches. If the parcel is not rectangular, measure each dimension where it is the largest. For a tube, use the diameter for both the width and the height.
  
  
• Round off each measurement to the nearest inch. For example, if the measurement is at least 6" but less than 6 1/2", round down to 6". But if it is 6 1/2" up to 7", round up to 7".
  
  
• Multiply the rounded length by the rounded width by the rounded height.
  
  
• If the piece is not rectangular, multiply by 0.785.
  

The volume surcharge applies if the result is more than 3,456.
