Get latitude/longitude from zip code

Is there any way (any API or any URL) to find the lat, long by passing the area code (zip code) only?

The Google Maps Geocoder will search on just zipcode.

Here is an example: (and a fiddle to see it working)

var geocoder;    
function initialize() {
    geocoder = new google.maps.Geocoder();
}

function codeAddress() {
    var address = document.getElementById("address").value;
    geocoder.geocode({
        'address': address
    }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            $('#coord').val(results[0].geometry.location);
        } else {
            alert("Geocode was not successful for the following reason: "
                  + status);
        }
    });
}

Google's free version of the API is restrictive when it comes to batch geocoding. If you need to geocode lots of data you may want to look into a geocoding service like: USC's geocoding service.

You could try using the yahoo geoplanet dataset. It includes geocoded zipcodes worldwide and a few other things. The main problem with this dataset is that it is no longer maintained so it may be missing newer postalcodes.

Otherwise, you could use a geocoder indeed. Google, Navteq, and Yahoo have such APIs though I don't know if they can geocode just postcodes.

You just need to use a database of this information; here's a free one.
