History of 412 Area Code
In 1947, the 412 area code was created and assigned primarily to the southwestern part of Pennsylvania. At that time, there was only one area code for that region. Later, in 1998, except in Allegheny County, the geographical regions were split, and the new area code 724 was implemented.
Again, in 2001, a new area code, 878, was implemented as an overlay for both the 412 and 724 area codes.

412 Area Code: Dialing Format, Prefixes & Network Coverage
The 412 area code uses a ten-digit dialing format for local calls, requiring the area code and seven-digit number. For domestic long-distance calls, simply add “1” before the full number, while international callers must first enter their country's exit code, followed by the U.S. country code (1) and the ten-digit number under the North American Numbering Plan (NANP).
Major telecom providers such as Verizon, AT&T, and Comcast offer strong coverage across the region. Within the 412 area code, phone numbers are assigned different prefixes such as 200, 201, 212, 220, 231, and 251, which are used by different carriers to organize number distribution across the network.
