Pennsylvania is currently using twelve area codes. Pennsylvania utilizes six area code overlay plans, often called overlay complexes.

Pennsylvania originally had four area codes when the numbering system was established in 1947. These four area codes were sufficient for forty-seven years until 1994 when area code 215 was split to form area code 610. Between 1994 and 2001 six new area codes were put into service in Pennsylvania.
