GOOGLE MAPS AUTOCOMPLETE state name rather than state code

I am using the google map autocomplete API to allow our customers to search for city, state, country formatted locations. Overall it is working well, but the problem is that while I am searching for a city, such as ‘Toronto’, it will give autocomplete output with abbreviated state names, for example, Toronto ON, Canada, as in the image below :

Example :

enter image description here

I want autocomplete output with state name rather than state code. For example, in the above image, it should instead say Toronto Ontario, Canada.

let me give another example : If I search for New York city, it will be output as: New York, NY, United States, but instead I would prefer that it be output as New York, New York, United States.

Is there some attribute that google provides us with which I could force the state names to be given in full, rather than abbreviated?

I have tried with some work-arounds to fix this issue, but I have so far failed to find a universal, working solution. Can anyone guide me on how best to accomplish this?

Answer

After doing a lot of research on the Google API docs, it seems like the feature you are requesting is not available natively within Google Maps API.

I worked up a work around below that works pretty well. It is a little complicated though, unfortunately.

The first part that is required is a function that loops through an array of international states / provinces with their short name.

JSON formatted international state / province abbreviations found here

function convertProvince(province, country) {
    
    // Variable containing all the international provinces with their short code
    var provinces = [{short:"AL",name:"Alabama",country:"United States"},{short:"AK",name:"Alaska",country:"United States"},{short:"AZ",name:"Arizona",country:"United

                                // Remove the trailing comma
                                province = province.substring(0, province.length-1)

                                // Remove any extra commas or whitespace
                                province = province.replace(/[,|s]/g, "");

                                console.log(predictionText);

                            }

                            // Create a new prediction row
                            var newRow = "<div class='prediction_rows'>" + predictionText + "</div>";

                            // New HTML to insert into the predictions container
                            newHTML = newHTML + newRow;

                        }

                        // Insert the new HTML into the predictions container
                        predictions_container.innerHTML = newHTML + "<img style='float: right' width='100' src='https://developers.google.com/places/documentation/images/powered-by-google-on-white.png' />";

                    }

                });

            }

        } (this.value), 500);

    });

init();

Main HTML:

<div class="container">

<input type="text" id="search" name="search" placeholder="search google places" style="width: 500px; margin-top: 50px;" autofocus>

<div class="predictions" id="google_predictions" style="width: 500px;">



</div>

I also made a quick little jQuery plugin to accomplish this as well, which can be found here on Github

Using the jQuery plugin you can implement it like so:

$("#ID_OF_INPUT_FIELD").addressAutocomplete();
