About Area Code 223
Area code 223 is a North American Numbering Plan (NANP) area code that has been in service since 2017. It is administered by NANPA on behalf of the FCC and serves the Pennsylvania region anchored on Harrisburg.
223 is an overlay code, which means it shares its geographic boundaries with one or more existing area codes (717). Overlays are created when a region exhausts the supply of phone numbers in its original area code. Within an overlay region, residents must dial all 10 digits even for local calls, because the same 7-digit number can exist under multiple area codes.
Mobile numbers in 223 are portable: a person who moved away from Harrisburg may still carry a 223 mobile number on their device. If you receive an unexpected call from a 223 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Pennsylvania, you may also interact with neighbouring or overlay codes (717). See the related codes section below to explore the rest of Pennsylvania.
