Eighty Four, Pennsylvania is home to headquarters of 84 Lumber.

The name origination is however much less interesting but still entertaining

“Eighty Four was originally named Smithville. Due to postal confusion with another town of the same name, its name was changed to "Eighty Four" on July 28, 1884. The origin of the name is uncertain. It has been suggested that the town was named in honor of Grover Cleveland's 1884 election as President of the United States, but that occurred after the town was named. Another possibility is the town's mile marker on the Baltimore and Ohio Railroad. Another is that the town was named after the year the town's post office was built, by a postmaster who "didn't have a whole lot of imagination."
