I have a form which would collect location information from the user. I'm using Google places api to autocomplete the location information. It works great. Everything got filled out nicely however there are some places (e.g. my workplace which is a building), Google does not return a postal code for it.

I followed this example from Google address autocomplete. It also doesn't return postal code for my workplace. So I'm not entire sure what I did wrong.

Below is my code:

HTML

    

        

            @Html.LabelFor(x => x.Address)
            @Html.TextBoxFor(x => x.Address, new { @class = "two-third-field", id = "street_number", required = "required" })
        
        

            @Html.LabelFor(x => x.UnitNumber, new { value = "Unit Number" })
            @Html.TextBoxFor(x => x.UnitNumber, new { @class = "one-third-field" })
        
        

            @Html.LabelFor(x => x.City)
            @Html.TextBoxFor(x => x.City, new { @class = "half-field", required = "required", id = "locality" })
        
        

            @Html.LabelFor(x => x.ProvinceOrState)
            @Html.TextBoxFor(x => x.ProvinceOrState, new { @class = "half-field", required = "required", id = "administrative_area_level_1" })
        
        

            @Html.LabelFor(x => x.ZipOrPostalCode)
            @Html.TextBoxFor(x => x.ZipOrPostalCode, new { @class = "half-field", required = "required", id = "postal_code" })
        
        

            @Html.LabelFor(x => x.Country)
            @Html.TextBoxFor(x => x.Country, new { @class = "half-field", required = "required", id = "country" })
        
        

JS

var placeSearch, autocomplete;
var componentForm = {
    street_number: 'short_name',
    route: 'long_name',
    locality: 'long_name',
    administrative_area_level_1: 'short_name',
    country: 'long_name',
    postal_code: 'short_name'
};

function initialize() {
    // Create the autocomplete object, restricting the search
    // to geographical location types.
    autocomplete = new google.maps.places.Autocomplete(
        /** @type {HTMLInputElement} */(document.getElementById('autocomplete')),
        { types: ['geocode'] });
    // When the user selects an address from the dropdown,
    // populate the address fields in the form.
    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        fillInAddress();
        showAddressComponent();
        setTimeout(hideAddressSearch, 800);
    });

}

function fillInAddress() {
    // Get the place details from the autocomplete object.
    var place = autocomplete.getPlace();

    for (var component in componentForm) {
        if (component != "route") {
            document.getElementById(component).value = '';
            document.getElementById(component).disabled = false;
        }
    }
    // Get each component of the address from the place details
    // and fill the corresponding field on the form.
    for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (componentForm[addressType]) {
            var val = place.address_components[i][componentForm[addressType]];
            console.log(val);
            if (addressType != "route") document.getElementById(addressType).value = val;
            else if (addressType == "route") document.getElementById("street_number").value = document.getElementById("street_number").value + " " + val;
        }
    }
}

// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(function (position) {
            var geolocation = new google.maps.LatLng(
                position.coords.latitude, position.coords.longitude);
            autocomplete.setBounds(new google.maps.LatLngBounds(geolocation,
                geolocation));
        });
    }
}

Screenshot

I wonder if this is a bug or simply Google doesn't know the postal code of the building. In that case, is there simply any work around this?

Thanks in advance.
