What is Area Mail Processing?
Area mail processing (AMP) is the consolidation of all originating and/or destinating distribution operations from one or more Post Offices™/facilities into other automated processing facilities for the purpose of improving operational efficiency and/or service.
Originating operations include canceling and sorting locally generated mail and destinating operations include sorting and preparing mail received from more distant areas for local delivery. The intent is to make more efficient use of Postal Service assets such as equipment, facilities, staffing, and transportation.
The Postal Service has developed a formal process for the review and implementation of Area Mail Processing proposals. This process is defined in Handbook PO-408, Area Mail Processing (AMP) Guidelines PDF | HTML.
