I'm creating an ecommerce app and we need the postal code to calculate shipping costs, using address autocomplete from google place api, not sure if it's a limitation from the api, but it doesn't return a postal code. I'm using https://github.com/FaridSafi/react-native-google-places-autocomplete for the autocomplete.

I looked through google docs as well, and it doesn't mention anything about it.

Just wondering if there's a way to get a postal code from an address?

The Google autocomplete API does not return a postal code as part of its results.

The package you mentioned has a fetchDetails props, which will call the Google Places API to get more information including the postal code. You can then access the data from details in onPress.

import React from 'react';
import { GooglePlacesAutocomplete } from 'react-native-google-places-autocomplete';

const GooglePlacesInput = () => {
  return (
    <GooglePlacesAutocomplete
      placeholder='Search'
      fetchDetails={true}
      onPress={(data, details) => {
        console.log('data: ', data);
        console.log('details: ', details);
      }}
      query={{
        key: 'YOUR API KEY',
        language: 'en',
      }}
    />
  );
};

export default GooglePlacesInput;

It works for me when I iterate through the array of objects (address_components) inside details, as you can see here:
