About Area Code 717
Area code 717 is a North American Numbering Plan (NANP) area code that has been in service since 1947. It is administered by NANPA on behalf of the FCC and serves the Pennsylvania region anchored on Harrisburg.
717 now shares its territory with an overlay code (223). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 717 are portable: a person who moved away from Harrisburg may still carry a 717 mobile number on their device. If you receive an unexpected call from a 717 number, run it through the reverse lookup tool above for the most accurate, free identification.
