Pennsylvania area codes — detailed data
Working detail for Pennsylvania's 15 area codes: history, capacity forecasts and dialing plans, straight from NANPA's NPA database.
Aggregate footprint: the state's 15 geographic codes currently carry 8,188 active NXX prefixes over 1,384 rate-center anchorings, with 6,242 prefixes in thousands-block pooling. 15 of the codes serve territory inside FCC top-100 metropolitan statistical areas.
Lineage: 223 came out of 717 in 2017; 267 came out of 215 in 1999; 272 came out of 570 in 2013; 445 came out of 267 in 2018; 484 came out of 610 in 1999; 570 came out of 717 in 1998; 582 came out of 814 in 2021; 610 came out of 215 in 1994; 724 came out of 412 in 1998; 835 came out of 484 in 2022; 878 came out of 412 in 2001. The remaining codes (215, 412, 717, 814) date back to the plan's early assignments.
Dialing plans: 15 codes use plain ten-digit local dialing (10D). Overlay territories always dial ten digits; the 2021 988-hotline transition moved most others to ten digits as well.
The tightest capacity in the state is 272 (complex 272/570), projected to exhaust 1Q 2038.
Status: no Pennsylvania code is currently in jeopardy or active relief planning — capacity is adequate near-term per NANPA.
