Does the MapPoint Web Service support ZIP+4 (10 digit ZIP codes like 99999-9999)? When I perform geocoding operations providing the ZIP+4, the "+4" part is stripped off; when I geocode providing the street address w/o the "+4" (which should provide enough info for the determination of the "+4" piece), I still just get back the 5 digit ZIP code. If ZIP+4 is NOT supported by the Web Service, this is a VERY SERIOUS shortcoming in the U.S. marketplace.
