Area code 304 serves the entire state of West Virginia and was one of the original area codes established in 1947. It remained the state’s sole area code until the introduction of 681 as an overlay in 2009, which brought mandatory ten-digit dialing. The code covers cities such as Charleston, Huntington, Morgantown, and Wheeling. West Virginia is known for its mountainous terrain, coal mining history, and Appalachian culture. Area code 304 is a powerful symbol of state pride and unity, often invoked in music, branding, and local identity. It remains one of the most iconic and beloved area codes in the country.
