How can I extract a Postal Code or ZIP of a place by giving Google Maps a city on the map?
Basically I'm looking for a free verification service for checking completed addresses for accurate details.
I seem to remember the maps API can somehow provide a geographical point when given an address. Now I'm searching for a slightly reversed situation in order to validate the postal code typed in with a city.
You need to Geocode the address to get best match coordinates
and then Reverse Geocode the coordinates to compare zip.
