Area code 878

Area code 878 serves Pennsylvania, including Beaver Falls, Pittsburgh Zone 1 and Washington (Eastern time). It has been in service since August 17, 2001.

Numbers starting with 878 drew 436 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 174 complaints to the FCC since November 2023. The number on your screen can be faked, so an 878 number proves nothing about where a call came from.

Phone companies holding 878 exchanges
