Get LatLng from Zip Code - Google Maps API

Question

All I want is some simple example code that shows me how to obtain a latlng element from an inputted zip code OR a city/state.

Is there a specific language your looking for your example to be in? — Mark, Apr 07 '11 at 18:57

Couldn't you just call the following replaceing the {zipcode} with the zip code or city and state http://maps.googleapis.com/maps/api/geocode/json?address={zipcode}

Google Geocoding

Here is a link with a How To Geocode using JavaScript: Geocode walk-thru. If you need the specific lat/lng numbers call geometry.location.lat() or geometry.location.lng() (API for google.maps.LatLng class)

EXAMPLE to get lat/lng:

    var lat = '';
    var lng = '';
    var address = {zipcode} or {city and state};
    geocoder.geocode( { 'address': address}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
         lat = results[0].geometry.location.lat();
         lng = results[0].geometry.location.lng();
        });
      } else {
        alert("Geocode was not successful for the following reason: " + status);
      }
    });
    alert('Latitude: ' + lat + ' Logitude: ' + lng);

This is not wrong but sometimes doesn't get some places even when google maps site does, the way that worked for me is: instead of this { 'address': zipcode} I replaced like this { 'address': 'zipcode '+zipcode }, i just added the string 'zipcode ' before the zipcode and it works better. — Geovanny Buitrago, Jun 09 '19 at 04:28

Just a hint: zip codes are not worldwide unique so this is worth to provide country ISO code in the request (https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2).

e.g looking for coordinates of polish (iso code PL) zipcode 01-210:

https://maps.googleapis.com/maps/api/geocode/json?address=01210,PL

how to obtain user country code?

if you would like to get your user country info based on IP address there are services for it, e.g you can do GET request on: http://ip-api.com/json

thanks for the hint, just using address=01210 did not deliver a correct result. with the ",PL" addition it works fine! — Havrin, Oct 30 '17 at 14:52

Here is the most reliable way to get the lat/long from zip code (i.e. postal code):

This is just an improvement to the previous answers because it didn't work for me with some zipcodes even when in https://www.google.com/maps it does, I fixed just adding the word "zipcode " before to put the zipcode, like this:

function getLatLngByZipcode(zipcode) 
{
    var geocoder = new google.maps.Geocoder();
    var address = zipcode;
    geocoder.geocode({ 'address': 'zipcode '+address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            alert("Latitude: " + latitude + "\nLongitude: " + longitude);
        } else {
            alert("Request failed.")
        }
    });
    return [latitude, longitude];
}

This was a big help for numbers like 12345 which give street address results by default. Thanks. In combination with a country-code suffix (,US) it does an even better job of assuming that an address is being provided, and not a business name. Good stuff, as long as you're searching only one country. — James Tomasino, Sep 03 '19 at 10:32

While working on my internship project I found a website for this https://thezipcodes.com/ Create a free account and get the API key from account Section.

https://thezipcodes.com/api/v1/search?zipCode={zipCode}&countryCode={2digitCountryCode}&apiKey={apiKey}

I found majority of data here.

Here is the function I am using for my work

function getLatLngByZipcode(zipcode) 
{
    var geocoder = new google.maps.Geocoder();
    var address = zipcode;
    geocoder.geocode({ 'address': address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var latitude = results[0].geometry.location.lat();
            var longitude = results[0].geometry.location.lng();
            alert("Latitude: " + latitude + "\nLongitude: " + longitude);
        } else {
            alert("Request failed.")
        }
    });
    return [latitude, longitude];
}
