Well, it's different because it's defined geographically, as a polygon, whereas UPS delivery zones and zip codes are defined as a set of addresses, which may or may not even be geographical (think APO addresses), and quite often don't map into a polygon. But I'm not saying that should matter. _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
