Placekey is a universal What/Where identifier for a given place. A Placekey is comprised of encoding for a Point of Interest (called "What") and 3 unique character sequences, built upon Uber's open source H3 grid system ("Where"). Use the Placekey API to query a Placekey by geocoordinates, address, city, region or postal code. Also Get Placekeys for multiple things at once using the Bulk method. Placekey identifiers are useful for sharing locations and location-related data across organizations easily.
