Need multiple country componentRestrictions in Google Places Autocomplete

Question

I need Google Places Autocomplete to give me results from countries: SZ, FR, DE, AT, IT. I know that componentRestrictions can operate with only one country. S

Answer 1

Be careful because if you restrict to "FR", it ignores the French overseas departments. So to have the cities in all of France, you need:

'fr', 'gp', 're', 'mq', 'gf', 'nc', 'yt', 'pf'

But since it's more than 5, it's not possible to limit to the whole of France.

Google Maps considers that the French overseas departments are not in France; this is a big problem.

Answer 2

Since version 3.2.7, you can use an array for componentRestrictions. Eg:

{ country: ["fr","ch","be"] }

The number of countries is, however, restricted to 5.

Answer 3

This feature was introduced in version 3.27 of Maps JavaScript API in January 2017:

You can now restrict Autocomplete predictions to only surface from multiple countries. You can do this by specifying up to 5 countries in the componentRestrictions field of the AutocompleteOptions.
