There is some requirements for that like you have to register your google account for that but it's very easy and you have to pass some parameter which is describe at there.

You can make using JSON or XML as per your requirements.

Answer 2

You haven't specified what country you're looking to do this for but you can use the GeoNames API for postalCodeSearch.

For example (XML and JSON responses respectively)

http://api.geonames.org/postalCodeSearch?postalcode=90210&username=demo
http://api.geonames.org/postalCodeSearchJSON?postalcode=90210&username=demo

Answer 3

Going a little more in depth, you can get a JSON encoded object from google from the following url:

http://maps.googleapis.com/maps/api/geocode/json?address=ZIPCODE&sensor=false

just replace the ZIPCODE with the zipcode that you would like and it should return to you a json object with the latitude and longitude coordinates.
