 A network distribution center, formerly known as a bulk mail center (BMC), is a central mail facility that processes bulk rate parcels as the hub in a hub and spoke network.
 An auxiliary sorting facility (ASF) is a central mail facility that processes bulk rate parcels as spokes in a hub and spoke network.
 A remote encoding center (REC) is a facility at which clerks receive images of problem mail pieces (those with hard-to-read addresses, etc.) via secure Internet-type feeds and manually type the addresses they can decipher, using a special encoding protocol. The mail pieces are then sprayed with the correct addresses or are sorted for further handling according to the instructions given via encoding. The total number of RECs is down from 55 in 1998 to just 1 center in December 2016. The last REC is in Salt Lake City, Utah.

While common usage refers to all types of postal facilities as "substations", the USPS Glossary of Postal Terms does not define or even list that word. Post Offices often share facilities with other governmental organizations located within a city's central business district. In those locations, often Courthouses and Federal Buildings, the building is owned by the General Services Administration while the U.S. Postal Services operates as a tenant. The USPS retail system has approximately 36,000 post offices, stations, and branches.

Automated Postal Centers

In the year 2004, the USPS began deploying Automated Postal Centers (APCs). APCs are unattended kiosks that are capable of weighing, franking, and storing packages for later pickup as well as selling domestic and international postage stamps. Since its introduction, APCs do not take cash payments – they only accept credit or debit cards. Similarly, traditional vending machines are available at many post offices to purchase stamps, though these are being phased out in many areas. Due to increasing use of Internet services, as of June 2009, no retail post office windows are open 24 hours; overnight services are limited to those provided by an Automated Postal Center.
