History of Area Code 412
Area code 412 was established in 1947 as one of the 86 original area codes in the North American Numbering Plan. It was an original code, so it was not created by splitting another area code. Its original territory covered a much larger part of western Pennsylvania than it covers today.
Area code 724 was created on February 1, 1998, by splitting territory from area code 412. The split moved much of the region outside Pittsburgh into 724. Area code 878 entered service on August 1, 2001, as an overlay for both 412 and 724.
