The NPAC service areas normally are defined by the boundaries of states included in each NPAC region. There is one exception, however, involving a portion of Northern Kentucky. Although Kentucky is part of the Southeast NPAC region service area, some Kentucky rate areas are defined instead to be part of the Midwest NPAC region. These rate areas are listed below. Network data for the NPA-NXXs and LRNs involving these rate areas must be populated in the Midwest NPAC's network data tables, not in the Southeast NPAC's network data tables.
