Obligatory mention that US ZIP codes come in 2 varieties, only the version
nobody uses is open:


   - Census zip codes that roughly and very loosely describe vague areas
   (plus a *huge* number of completely weird ones nobody would recognize
   where the Postal Service does *not* deliver), and these are open.
   - Postal service 9-digit (aka "ZIP+4") variety that describes a specific
   postal route and group of destinations (usually no more than ~10-12; the
   trailer park I lived in had *14* zip+4s for a single multitenant
   property despite all ~240 mailboxes being on the same street corner), not
   areas.  These are proprietary and the only ZIP you'll find in addresses.
