The 878 area code was created as an overlay on 412, giving Pittsburgh room to grow without shuffling existing numbers. Interestingly, no 878 numbers were actually handed out for over a decade after activation, with the first ones going live in April 2013 [1]. Today it covers the same ground as 412, so a customer in Squirrel Hill sees it the same way they see any local number.
Pittsburgh has quietly become one of the more interesting business towns in the northeast. In 2026, 14 Pittsburgh-area companies made the Inc. 5000 list of fastest growing private firms, with a Robinson-based mortgage lender leading the pack at 673% growth [2]. AI and machine learning are the loudest verticals right now, but healthcare, education, and the trades still anchor the neighborhoods where most small businesses actually operate [3].
If you're taking calls from folks in Mount Lebanon or Monroeville, an 878 number reads local in a way an out-of-state toll-free line never will. Pittsburghers notice these things. Answering with a familiar area code is often the difference between a voicemail and a real conversation.
