Prior to the launch of the Delivering for America plan, the U.S. Postal Service used Surface Transfer Centers to distribute, consolidate, dispatch, and transfer all mail classes within the surface network. They also served as a concentration point for consolidating mail from under-utilized surface trips. In September 2024, the Postal Service transitioned to the use of RTHs. RTHs are intended to decrease the number of mail separations and fill containers quickly during processing to expedite getting mail onto trucks and out for delivery to customers.
As of March 2025, 18 RTHs were active nationwide. While the Postal Service indicated that work handled at RTHs would be insourced, some RTHs, such as the Denver RTH, continue to be operated by contractors rather than Postal Service employees.
