Efficiency of Surface Transfer Centers in the Southern Region

Surface Transfer Centers (STC) are contracted mail facilities that distribute, consolidate, dispatch, and transfer all mail classes within the surface network. They also divert mail volume from air to surface transportation and serve as a concentration point for consolidating mail from under-utilized surface trips. There are 13 STCs in the U.S. Postal Service network, four of which are in the Southern Region. These facilities are an integral part of the Postal Service’s plan to optimize its transportation by moving more mail on the surface network.
