Hello amazing community members, 

Effective July 9, 2023 USPS services and rates will undergo some notable changes. We'll break down these changes and ensure you're well informed and prepared for the upcoming adjustments.

New Service: USPS Ground Advantage™  

This new service offering combines USPS Retail Ground®, First-Class Package®, and Parcel Select Ground® services and return options like First-Class Package Return® service and Ground Returns. You will be able to ship packages up to 70 pounds with an expected delivery of 2-5 business days with tracking and $100 loss and damage coverage. 

What steps do I need to take? 

ShipStation will be aiding you in this transition by automatically mapping any of the selected consolidated services to USPS Ground Advantage through the end of 2023. 

 We would recommend updating your automation rules and any service mappings,  before the end of the grace period. If you try to use any of the consolidated services after the grace period you will receive an error message. If you have any outbound or return labels associated with the services that will no longer be in use, USPS will honor those labels until September 30, 2023.
