USPS Priority Mail 2020 Rate Changes

Priority Mail is the core parcel shipping service for USPS. It’s a versatile shipping service that is used to ship millions of packages each day.

Below we’ve put together an example of a 4 lb. package and compared 2019 rates to the new 2020 rates going to various zones:

USPS First Class Package 2020 Rate Changes

First-Class Package service has been the most popular and cheapest USPS service to ship packages under 1 lb. In 2019, this service saw a major change to the pricing structure. Many merchants navigated the changes smoothly, though it certainly made shipping with First-Class Package Service more complicated and expensive for small and medium-sized businesses.

An important element to note is that the First-Class Package Service rates for packages going to Zones 1 & 2 and weighing 1 to 4 oz will be increasing by 3.01 percent. This is a jump from last year, as the rates stayed the same from 2018 to 2019. This is among the highest increase among weights and zones in this shipping method and will affect many merchants who ship lighter packages nearby.

The same is also true for First-Class Package International Service. Group 1 pricing for First-Class Package International service increased by an average of 20.80 percent, substantially more than nearly every other pricing group other than Pricing Group 3 (21.73 percent).

Regional Rate Shipping 2020 Rate Changes

Regional Rate service is a less-used but useful shipping service. This method lets you ship using preset boxes you can order online, and the rate is cheaper when shipping short distances. Both Regional Rate Box A and B rates increased across all zones. Regional Rate shipments are mainly designed to be shipped to Zones 1-4, and that is certainly reflected in the Zone 9 increases below.

Parcel Select Ground 2020 Changes

Last year, Parcel Select was the only service where we saw numerous rates decrease. That’s not the case this year, as rates increased across the board by an average of 2.5 percent for Parcel Select. We’ve used an example of a 5-pound package to show the changes across zones for Parcel Select shipping rates. Note that this is a much slower service and doesn’t come with the benefits that Priority Mail comes with. Those added benefits often make Priority Mail worth paying the slightly higher rates.
