Buy a Local Phone Number – Area Code 878 (Pittsburgh, Pennsylvania)

Covering Pittsburgh and surrounding counties, area code 878 was approved in 2001 as an all-services overlay for 412 and 724 after the 1998 split, cementing 10-digit dialing across western Pennsylvania. Its creation reflected mounting demand from wireless lines, internet services, and business growth; widespread assignment of new numbers followed in the early 2010s as legacy inventories tightened. The overlay links Allegheny County with neighboring industrial valleys and suburban corridors, keeping established communities and newer developments under a unified dialing plan.
