This means that reverse geocoding to find actual addresses in pretty much useless. Maybe I am formating my request wrong, or missing a flag?
PlaceFinder may return nonexistent addresses; the returned address is just an approximation. PlaceFinder uses address interpolation to identify the nearest house/building to the input coordinates. Address interpolation means that we start with the address range assigned to a block and then assign an address based on the number of potential addresses and the relative position of the input coordinates along the block.
