412 originally covered all of southwestern Pennsylvania. The 1998 split created 724 for the suburbs and surrounding counties, leaving 412 with just Allegheny County (Pittsburgh and inner suburbs). Overlay 878 was added in 2001. Despite the overlay, a 412 number remains the heritage signal for established Pittsburgh businesses — including the city's healthcare giants (UPMC, Highmark), banking sector (PNC, Mellon), and the robotics and AI research clusters around Carnegie Mellon University.
