Cranberry Township is in Butler County. It is not in Allegheny County, and it is not part of the City of Pittsburgh, even though many listings and businesses market it as North Pittsburgh. That one fact changes your tax bill, your county services and your school district.
Here are the ZIP codes, the county line, and what your Cranberry address actually tells you.

What county is Cranberry Township in?
Butler County. Cranberry sits at the southwest corner of the county, and its southern border is the Allegheny County line, where it meets Pine Township and Marshall Township. The county seat is the City of Butler, north of Cranberry.
That is why so many people assume Cranberry is in Allegheny County. You can cross from Cranberry into Marshall or Pine without noticing, and the stores, roads and commutes all point toward Pittsburgh.
