Local Exchange Carriers

Telephone exchanges in Kentucky define a geographic area in which telephone prices and services are the same. This may be referred to as a rate area. The concept of exchange area is based on geography and regulation, not equipment . An exchange area polygon has only one operating company, which may be referred to as a local telephone company or incumbent local exchange carrier (ILEC or LEC). Area Codes and LATAs (Local Access Transport Area, which is the area local telephone companies are permitted to offer local or long distance telecommunications services), are defined by grouping exchange areas.
