Pennsylvania (blue) with numbering plan area 724 shown in red.
Area code 724 is a telephone area code in the North American Numbering Plan for the Commonwealth of Pennsylvania in western and southwestern Pennsylvania, including a portion of the suburbs of Pittsburgh. It was created in an area code split of area code 412 on February 1, 1998, which made the 412 numbering plan area (NPA) an enclave for the city, with 724 surrounding 412. In 2001, area codes 412 and 724 were overlaid with area code 878, so that the entire southwestern corner of Pennsylvania is served by area code 878.
