Question

been trying find a way to extract postcode from latlng position but im not entirely sure how to do it. can someone point me to the right direct please, im using google api autocomplete.

I tried using address_components but it only gives me short/long names and types.

Answer 1

You will need to use another service for this. postcodes.io is free, open source and uses open data. The request you are looking for is:

GET api.postcodes.io/postcodes?lon=:longitude&lat=:latitud e

Get the long lat from google maps and then make a separate request to a postcode service to get the postcode you are looking for.

The service above covers UK postcodes only. You may need to use multiple services for different countries.

Answer 2

if the data returned were called "addresses"...

var arr = addresses.results[0].address_components,
    i = 0,
    len = arr.length;
for (i; i < len; i++) {
    if (arr[i].types[0] === "postal_code") {
        alert(arr[i].long_name)
    }
}
