About area code 878
Area code 878 is one of the North American Numbering Plan (NANP) codes serving Pennsylvania. In the NANP a full number looks like +1 (878) NXX-XXXX: the +1 is the country code for the US and Canada, 878 is the area code, and the remaining seven digits identify the specific line. A call is charged by your own carrier's plan, not by the area code itself.
