postal_code or addr:postcode are for a ZIP code itself, while addr:city 
is for the name of the city or P.O. station the ZIP code is associated 
with. The typical usage would be: addr:city=Boston addr:state=MA 
addr:postcode=02134.

Still, any attempt to draw a bubble around a ZIP code is going to raise 
the same questions: How precise is the bubble? Is one edge exact and the 
other hand-wavy? How would one tag the degree of uncertainty in a 
machine-readable way (that is, other than FIXME)?
