ExchangeInfo PLUS is a comprehensive telecommunications infrastructure database that contains geographic and industry data on Wire Center boundaries, and Central Office and wireless switch locations. Wire Centers are the basic unit of geography for the telecommunications industry in the United States. They describe the organization of the local telephone exchange system. Each Wire Center serves a unique set of telephone numbers within a fixed geographic area.

ExchangeInfo PLUS is built using over 50 million addresses, telephone tariff data, and MapInfo's proprietary technology and processes. It includes every Wire Center in the United States (over 22,000), graphically displaying their service areas.

MapInfo's core telecom infrastructure database, ExchangeInfo PLUS is updated on a monthly basis, to make sure it contains the most accurate, timely telecom infrastrcuture data available.

ExchangeInfo PLUS is currently scaled to 1:24,000 using the latitude/longitude coordinate system and NAD 83 datum.
