Since your question is tagged iPhone, I assume you're doing this on the iPhone. If that's the case, why not just use MapKit?

Use the MKReverseGeocoder class which, given your latitude/longitude pair, will send -reverseGeocoder:didFindPlaceMark: to its delegate. The placemark has a postalCode property.

If you really need a web service, I've looked at the following services for geocoding (not reverse-geocoding). You might want to look at them to see if any of them suits your needs:

• Google
• CloudMade
• Tiny Geocoder
• Yahoo
• TeleAtlas (not purely a web service)

I've done limited testing of each of these services with the exception of TeleAtlas. For my purposes, Google and Tiny Geocoder returned the best results. YMMV.

CloudMade supports reverse geocoding...
