304 Area Code: Charleston, West Virginia

West Virginia is served principally by the 304 area code, the long-running designation for the entire state. Charleston, on the Kanawha River, anchors the directory's records here. The city sits at the confluence of the Elk and Kanawha rivers in central West Virginia, organized around the West Virginia State Capitol, a downtown core, and a long-running role as the regional commercial and political center for the surrounding state. The local working economy reflects state government, healthcare (Charleston Area Medical Center is among the larger employers), the surrounding chemical-manufacturing base in the Kanawha Valley, and the broader coal-and-natural-gas economy of West Virginia. The 304 footprint takes in Huntington, Morgantown (West Virginia University), Wheeling, Beckley, and the rest of the state.

Because 304 covers West Virginia alongside the more recent 681 overlay, the directory's records associated with 304 numbers do not surface a recurring set of out-of-state cities through the routine cross-linkage patterns that dominate larger codes. Where other-place names do appear, they reflect standard public-record dynamics — numbers porting between carriers, addresses tied to multiple residences, and prior registrations surfacing alongside current ones. The directory currently documents 641 distinct prefixes within 304 in detail, a working subset of the prefix population the code carries.

Charleston's median age sits notably above the US figure, in the low forties, a pattern shaped by long-standing residents and slower in-migration relative to most of the country. Median household income runs below the national reading, home values come in below the US median, and population is modest in absolute terms — Charleston is the largest city in West Virginia but small in the broader US frame.
