History of Area Code 223

Area code 223 was established on March 28, 2017, as an overlay for area code 717. The Pennsylvania Public Utility Commission approved the new code after 717 neared exhaustion. Existing 717 customers kept their numbers, and new numbers in the same region could receive either 717 or 223.

Area code 223 did not split the region. It overlays the same geographic territory as 717, which is one of Pennsylvania's long-standing area codes and dates back to the original North American Numbering Plan in 1947. Because of the overlay, 10-digit dialing became necessary for local calls in the 717 and 223 service area.
