Other Area Code Details
Area code 878 was introduced in 2001 as an overlay to address number exhaustion in the Pittsburgh region. It was one of the first area codes in the US to be introduced as an overlay rather than a split, requiring 10-digit dialing for local calls. Pittsburgh, the core of the 878 region, is known for its rich sports culture, numerous universities, and historic role in the US steel industry.
