What is 814 area code?

The 814 area code is a North American telephone area code in the state of Pennsylvania. It covers the central and northwestern parts of the state, including cities such as Erie, Altoona, State College, and Johnstown. The 814 area code was established in 1947 as one of the original area codes in Pennsylvania. It is currently the largest area code in the state in terms of geographic coverage. In 2018, the Pennsylvania Public Utility Commission approved an overlay plan that will add a new area code, 582, in the same region as the 814 area code to meet the increasing demand for phone numbers in the area.
