Area code 717 is a telephone area code which serves south central Pennsylvania, used in the Harrisburg-Lancaster-York metropolitan areas. 717 was one of the original area codes established in 1947, and originally covered the eastern half of the state except for the Delaware and Lehigh valleys. The 717 area code was split on December 5, 1998, when the northeastern portion became area code 570.
Of the total numbers that telephone companies have in the 717 area code, as of May, 2005, 52% were given to customers and 48% were still unassigned. On July 1, 2009, the North American Numbering Plan Administration (NANPA) reported that the 717 NPA would exhaust the available number pool by late 2013.
The recommendation is to overlay 717 with a yet-to-be-assigned area code, although a split has not been ruled out.
