Yeah, I always thought that was a bit of an aCkTcHUuaLly type of point. Okay, okay, it's about routes. But, when you can draw perfectly mutually exclusive convex hulls around the unions of the lots receiving mail for a given zip code, then you can draw zip code polygons.

The Pentagon has six zipcodes and they're divided up by floor.

(My standard example used to be the World Trade Center, which had two - not one for each tower, but one for the state government offices and one for everything else.)

This is a much better point that I didn't even think of!
