Area codes 304 and 681 are telephone area codes in the North American Numbering Plan (NANP) for the entirety of the U.S. state of West Virginia. The numbering plan area was established in October 1947 with area code 304, as one of the 86 original North American area codes. Area code 681 was added to the same area as an overlay in 2009.
