On July 9, 2023, USPS introduced a new ground-based package service: USPS Ground Advantage. This service replaces USPS First-Class Package Service, Parcel Select Ground, and Retail Ground. First-Class Mail Letters and Large Envelopes/Flats will continue to be available. Ground Advantage delivers packages within the Continental United States in 2-5 business days with free tracking and $100 of USPS insurance for packages between 0 and 70 lbs.

Recent builds of Ship Connect Multi-Carrier and NRGship FM for USPS support the new USPS Ground Advantage option. Previous builds have existing First-Class and ParcelSelect services re-mapped to the new USPS Ground Advantage. Cutomers using these services should plan to upgrade their solution files before end-of-year 2023 for continued service availability.
