Placekey - Address Matching and Entity Resolution


Get your datasets to speak to each other with Placekey, the universal ID for any physical place.

Placekey serves as a standard universal identifier for any physical place, so that information pertaining to those places can be shared easily across organizations and datasets. This Add-in exposes the full functionality of the Placekey API in order to quickly add Placekeys to your address and geocoding data, right from Microsoft Excel.

How can I use Placekey?

Placekeys solve a number of common problems for data scientists. As a unique identifier for any physical place, Placekey simplifies the process of joining both POI or non-POI datasets. Placekey also reveals relationships between POIs and addresses, providing details such as proximity, co-tenancy, and POI history. Even places without addresses can be appended with a Placekey.

Placekey Details:

Each Placekey is divided into two parts: What and Where, written as “What@Where”. The What part encodes information about the place and its address, while the Where part situates that place on Earth. The What part of a Placekey is optional, and a Whatless Placekey like “@5vg-7qg-tvz” refers to a region on the Earth while a What part plus a Where part specifies a particular place within a region on the Earth. The Where part of a Placekey encodes a hexagon of approximately 15,000 m2 on the surface of the Earth. These hexagons have an edge length of 66 m on average, and it can be helpful to think of them as roughly circles with a diameter of 132 m. The exact area and edge length of the hexagon varies by location. In particular, these hexagons are given by resolution 10 H3 indices.
