Hi .. I need a public web service that can process the US zip code provided and respond if its valid or not. Also, if it could provide additional information like state, city information associated with the zip code it would be helpful. I tried a few services like USPS, Zipwise but I am not able to find a direct wsdl from them. Any pointers would be helpful.
