Does the Postal Service Need International Service Centers?

The Postal Service established International Service Centers (ISCs) in 1996 to become more competitive in the international mail market. ISCs distribute and dispatch both incoming and outgoing international mail. The ISC network has facilities located in five major cities: New York, Miami, Chicago, Los Angeles, and San Francisco. The Postal Service hoped that ISCs would improve service and provide the structure needed to support new products and increase revenue.
