History of Area Code 412

Area code 412 is one of the original North American area codes created in 1947. At first, it covered the entire western part of Pennsylvania. It served a much larger region than it does today.

Area code 412 was reduced in size through later splits as telephone demand grew. In 1998, most of the old 412 territory changed to area code 724, while 412 remained with Pittsburgh and nearby areas. In 2001, area code 878 was added as an overlay for the 412 and 724 region, which made 10-digit dialing necessary in the area.
