History of Area Code 717

Area code 717 was created in 1947 as one of Pennsylvania's original area codes under the North American Numbering Plan. It originally covered a much larger part of eastern Pennsylvania. In 1994, the eastern part of its territory was split off to create area code 610.

Area code 717 remained in use across south central Pennsylvania after the 1994 split. As demand for phone numbers grew, the Pennsylvania Public Utility Commission approved an overlay. Area code 223 was added as an overlay for the same geographic area in 2017, and 10-digit dialing became necessary for local calls in the 717 region.
