I have the geonames database but I need to get the postal code based on latitutde and longitude , geonames.org has such a service but the data is not accurate. Google api reverse geocoding offers a more accurate data regarding postal codes. Is it right that google geocoding api must be used with google maps, or can I use this google reverse geocoding api without displaying results on a map.
If not, does anyone know any other solutions other than geonames postal codes service in order to get the postal code based on lat. lng. ?
I want to copy and insert this postal codes into my geonames database.
I don't want to display the results on a map.
