2021 USPS® Peak Holiday Shipping
Rate Increase
Effective October 3

The USPS announced a temporary rate adjustment for packages that will be in effect from Sunday, October 3, 2021, through Saturday, December 25, 2021. The USPS first introduced a peak holiday shipping rate increase in 2020. The seasonal adjustments are designed to address the higher handling costs associated with holiday shipping activity and are in line with competitors’ practices. 

 

The USPS peak shipping rate increase impacts these specific USPS shipping services: Priority Mail Express®, Priority Mail®, First-Class® Package Service, Parcel Select, Parcel Return Service, and USPS Retail Ground. For 2021, the peak holiday rate increase will include Post Office retail and commercial shipping rates. International shipping products are not impacted.


Below you’ll find the 2021 USPS holiday rate increases.

Commercial pricing with SendPro is a great way to offset the peak increase by switching to USPS shipping labels rather than using stamps or a meter tape for First-Class packages.

  • By printing complete, trackable IMpb USPS shipping labels with our SendPro solutions, you save even more with Commercial Base discounts. 
  • Even after the peak increase, an 8 oz. package sent to Zone 4 with SendPro is $1.09 (22%) cheaper than the same package sent in January using Retail rates (see below).
