The original four area codes for Pennsylvania in 1947 were 215, 412, 717, and 814. 610 was added in 1995, and several other splits and overlays have occurred since then. As a result, the entire state is composed of overlay regions and 10-digit dialing is mandatory statewide. Area code 835 is planned as an additional overlay with 610.
