About Google Maps IDs

Response Parameter: place_id

Each entry in the Google Places database is assigned a Place ID.

Place IDs are unique identifiers.

Place IDs are only returned when an extended call is made and a result is obtained from Google Places. See Restrictive vs Extended.

Place IDs can be used to obtain other information about the place.

Place IDs can be cached indefinitely.
