I used to live at a fractional address and it was pretty much impossible to represent your address accurately in a lot of systems.

I ended up usually writing it as "200h" instead of "200 1/2".

Worked surprisingly well. One of the advantages of having deliveries still carried out by actual people where the address apparently doesn't have to be an exact match.

Yes, I suppose as long as the street name is recognized it will usually go to the right carrier, at least for fairly short streets.
