Assigned at the launch of the North American Numbering Plan in 1947, area code 304 covered all of West Virginia. For more than six decades the state kept that single code, a reflection of its population size and dispersed settlement patterns. Charleston, the capital on the Kanawha River, anchored many statewide services and media markets. Rising wireless adoption and new carriers in the 2000s prompted an all-state overlay; 681 was introduced in the late 2000s, and 10‑digit dialing became standard while existing numbers were retained.
Telephone demand has followed the region’s economic shifts. Coal and rail forged the early network; the Kanawha Valley’s “Chemical Valley” era brought intensive industrial traffic; and recent decades emphasize government administration, healthcare systems, education, energy services tied to natural gas development, and distribution along the I‑64/I‑77 corridor. Appalachian geography—mountainous terrain and small towns in hollows—long sustained independent telcos and party lines, later consolidated into fiber routes paralleling rivers and highways. Cultural life in and around Charleston, including events like FestivALL and the Vandalia Gathering, as well as old-time music and crafts, underscores a statewide identity that many residents still associate with 304 even as the overlay broadened numbering capacity.
