A Brief History of Area Code 223
Area code 223 was activated in 2018 as an all-services overlay on the 717 region. The 717 code is one of the original 1947 codes. An overlay adds a second area code across the same geographic area, so existing 717 customers kept their numbers while new lines could be assigned either code, under mandatory 10-digit dialing.

Numbers in the 223 area code use Eastern Time (ET). The region observes Daylight Saving Time, shifting from EST (UTC-5) to EDT (UTC-4) between March and November each year.
