LATA: Local Access And Transport Area
Local Access And Transport Area (LATA) refers to the areas within which the Bell Operating and independent telephone companies can provide telephony services. Inter-LATA connections must be provided by Interexchange or long-distance carriers. This was created by the 1984 divestiture and defines a geographic area in which a local exchange carrier, or LEC provides services or connectivity. Traffic that crosses from one LATA to another is the exclusive domain of the IXC. The 358 LATA covers the Chicago area from roughly the Wisconsin state line to just South of Kankakee, and just West of Aurora and Ottawa to Lake Michigan and the Indiana state line.
