A zip code is part of every USPS address, yes. But unless you are going to
map zip codes as huge multipolygons of thousands of individual buildings
each (in some cases probably overlapping), that doesn't make them geographic
If you *really really* want zip codes in OSM, then put them in
addr:postcode, on buildings or nodes (by themselves or as part of an
interpolation way). Or better yet use a relation (since a zip code is
actually a relation, not an area). But personally I think even that is
better stored in an external database.
