Get only country specific result using google geocode api

Question

I am using google geocode api for fetching lat long using postal code of singapore

I have tried following to fetch data:

(1) http://maps.googleapis.com/maps/api/geocode/json?address=505468&sensor=false

(2) http://maps.googleapis.com/maps/api/geocode/json?address=Singapore%20505468&sensor=false

(3) http://maps.googleapis.com/maps/api/geocode/json?address=Singapore%20505468&sensor=false&region=sg

But it returns location from India

https://developers.google.com/maps/documentation/geocoding/?hl=fr#RegionCodes

Any other way to get only country specific (Singapore) result.

I have tried following it returns correct result

http://maps.googleapis.com/maps/api/geocode/json?address=Singapore%20133224&sensor=false

Answer 1

The correct way of doing this is by providing componentRestrictions

For example:

var request = {
    address: address,
    componentRestrictions: {
        country: 'UK'
    }
}
geocoder.geocode(request, function(results, status){
    //...
});

Answer 2

To restrict results to a specific country use the component-filtering.

The url should be http://maps.googleapis.com/maps/api/geocode/json?address=Singapore%20505468&sensor=false&components=country:SG

But that's not the issue here, the geocoder-result is wrong, because the result has the country set to SG, but the location is wrong(placed in india).

I'm afraid with the given address(it appears that the postcode doesn't exists), the only thing you can do is to report the wrong result to google.
