What is the best data source for determining international postal codes given a latitude & longitude?
EZ-Locate (TeleAtlas - owned by TomTom)
NAVmart (NavTeq owned by Nokia)
Via Michelin (API and better coverage in Europe rather than globally)
Geonames (good open-source - patchy accuracy in rural locations)
