Find any 717- phone number in Pennsylvania

The 717 area code is a North American Numbering Plan (NANP) area code assigned to a portion of Central Pennsylvania. It has served the area since 1947, when it was split off from region 201, which at that time covered all of Pennsylvania. This region encompasses the cities of Harrisburg, Lancaster, York, Reading, and many other municipalities in southwestern Pennsylvania.

The NANP is the system by which telephone numbers are assigned throughout Canada, the United States, and certain Caribbean countries. This ten-digit system separates each country from another, and for the United States, area codes are assigned to various regions within the country. This helps to ensure that no two telephone numbers will be identical, as geographic lines can be assigned unique area codes depending on its respective population size. This numbering system allows for an easier communication and navigation of calls both nationally and internationally.
