Place Autocomplete Address Form

Does your application include an address form, such as the shipping address for an online order, a credit card billing address, or a ridesharing booking form? Autocomplete can help users supply the details.

The Place Autocomplete Address Form sample captures selected address components from the Google Places database, and uses them to populate an address form.

Since this sample only requires a place address in a structured format, the sample code uses just one place data field: address_components. The requested place data fields affect the cost of each request. You can specify which place data fields to return by calling Autocomplete.setFields(), and specifying one or more place data fields.

The address components in this sample are based on a typical address format. Note that you might need to use a different set of components to align with the postal address formats used in some regions. For example, the sample code selects the locality component, which often represents the city part of the address. Examples of how components can differ include:

  • In the UK and in Sweden, the component to display the city is postal_town.
  • In Japan, components differ across prefectures.
  • Brooklyn and other parts of New York City do not include the city as part of the address. Instead, they use sublocality_level_1.

When the user selects an address from the pick list, your application can populate the address form.
