Was our address for sixteen years incorrect ? Why or why not?

All my growng up years the front of our home faced Sherman Street, on the corner. But all that time until now our house was/is listed as being on another street but that part of the house is the side of the house. The house next door faced Sherman Street and it was listed correctly. How did this happen or is it not really a mix up at all? There are only two houses on that block that face Sherman Street: mine and the neighbor’s.
