Area code 412
Area code 412 is a Commonwealth of Pennsylvania telephone area code which serves most of Allegheny County, Pennsylvania (including Pittsburgh), along with small portions of Washington and Westmoreland counties, except the northern edge of Allegheny County served by the Consolidated Communications, formerly the North Pittsburgh Telephone Company, including Wexford and Gibsonia. Area code 412 was one of the original area codes established in 1947, and originally covered the entire southwestern corner of the state. On February 1, 1998, nearly all of the old 412 territory outside of Allegheny County was split off into area code 724, which surrounds 412.
