Michigan telephone exchange map

The MPSC, in partnership with Connect Michigan, has compiled a map of Michigan’s local telephone exchanges. These exchanges show the service territory of an incumbent local exchange carrier (ILEC), with some ILECs serving multiple exchanges and some serving a single exchange in the state. There are also some small areas such as uninhabited islands and other unoccupied areas that are currently unassigned and not served by a wireline telecommunications provider. The interactive map outlines the exchange boundaries and clicking on one will display the name of that exchange and which ILEC serves that territory.

The data used to display the telephone exchange boundaries on the map has been compiled by Connect Michigan and the Michigan Public Service Commission using publically available state and federal data sources. While all efforts have been made to verify the accuracy of these boundaries, given the type and variety of the data sources used, errors are possible and the accuracy of the boundaries is not guaranteed. If any discrepancies are found, please contact the MPSC’s Telecommunications Division at 517-284-8190.
