Area code 814 serves a large swath of northwestern and central Pennsylvania, including cities like Erie, Altoona, State College, and Johnstown. Established in 1947, it remains one of the state’s original area codes and is overlaid by 582 as of 2021. The region blends natural landscapes, college towns, and post-industrial communities. State College, home to Penn State University, is a major educational and economic anchor. Ten-digit dialing is now required. Area code 814 stands as a longstanding symbol of Pennsylvania’s rugged charm, academic strength, and working-class heritage.
