North American NumbersErie/Altoona/State College
One of the original 1947 area codes, 814 is the largest NPA in Pennsylvania and the only one of the state's four original codes to keep its original boundaries; it is overlaid by 582.
Status, dates and counts are read from NumberResearch (NANPA / CNAC / FCC records). Assignment records show initial assignees, not the carrier serving a number today.
Where 814 is
Northwestern and central Pennsylvania.
Communities served wholly or partly by 814:
Spans parts of twenty-seven counties from Erie in the northwest to Somerset in the south-central region.
How it relates to other codes
The codes 814 was split from, spawned, or shares its area with. A split divides the map and changes some numbers; an overlay shares the same ground and changes none — what's the difference?
