Welcome to Rate Change Central

Starting June 23, the USPS will implement changes to how dimensional (DIM) weights are calculated. The DIM weight divisor will change from 194 to 166, which increases the price for packages subject to DIM weight pricing. The USPS is also changing the zones and postal products affected by DIM weight pricing.

Overview of postal changes




First Class Mail and Commercial Base pricing – Your Pitney Bowes postage solution provides you more value than ever.

First Class® Mail – Metered Mail saves you even more.

The cost of First-Class Mail Letters will increase from 50¢ to 55¢. That’s a significant increase. The good news is that the discount for Metered Mail Letters (Meter and online postage users like SendPro) increases to 5¢ for every 1 oz. First Class Letter. The 5¢ savings for 1 oz. Metered First Class Letters represents a 9% savings that can add up quickly. For example, a small business sending 500 pieces of mail per month can save $300 a year.

Priority Mail rates will increase for most packages by an average of 6.2% and Priority Mail Express will increase by an average of 3.9%. Priority Mail Commercial will only increase by an average of 3.2%. This means you’ll save even more by printing a trackable (IMpb) label using SendPro Online, or your shipping app on SendPro C-series or SendPro P-series device (up to 40.4%). Printing a trackable label qualifies you for Commercial Base discounts without any volume requirements. Priority Mail Commercial Base, heavier items (11 lbs.+) traveling to all zones and medium weights (4 to 10 lbs.) sent to Zone 5 will see rate decreases vs. 2018.

First Class Packages will be more complex.

In an effort to standardize its package services, the USPS plans to price First Class Packages based on weight and zone. First Class Packages were previously priced based on weight alone. This means First Class Package services will be more comparable to other USPS shipping products such as Priority Mail and Priority Mail Express.

In 2018, a 12 oz. First Class Commercial Parcel was $3.82, regardless of where it was being sent. In 2019, that same 12 oz. package could be $3.82 to $4.33, depending on the zone where it’s being sent. Even with the change, First Class Package Services remains a cost-effective method for shipments that weigh less than 1 lb.

Prepare for the DIM Weighting Change planned for June 2019.

The USPS is decreasing its DIM weight divisor from 194 to 166. This makes it more important than ever to choose the right type of packaging for what you’re sending. DIM weight can make lighter packages in larger boxes, that take up more room, cost more than heavier items in smaller packaging. So if you send a 2 lb. item in a box that measures 12” x 12” x 12”, using the USPS cubic inches calculation of 12 x 12 x 12 divided by 166, the dimensional weight of this package becomes 11 pounds, or almost 6 times more than its actual weight. We will eliminate the guesswork by helping you to apply the accurate postage for your package no matter the weight and dimension.
