How it Works

Introducing

Placekey is a free, universal standard identifier for any physical place, so that the data pertaining to those places can be shared across datasets and organizations easily.

How Does it Work?
The What & Where of a Place

Placekey is a string that follows a What@Where structure. This is a unique way of shedding light on both the descriptive element of a place as well as its geospatial position in the physical world via a single identifier.

The Where of any physical place

The Where Part, on the other hand, is made up of three unique character sequences, built upon Uber’s open source H3 grid system. This information in the Where Part is based on the centroid of that place. In other words, we take the latitude and longitude of a specific place and then use a conversion function to determine a hexagon in the physical world, representing about 15,000 sq. meters, containing the centroid of that place. The Where Part of the Placekey is, therefore, the full encoding of that hexagon.

For Developers

For people building products, Placekey's free API service appends the Placekey universal location ID to any address, POI, or latitude and longitude combination. That's a lifesaver for solving difficult address and POI matching problems and performing entity resolution. Read our case studies to learn how developers and data scientists are using Placekey to build products.

For Data Sellers

Whether you sell property data, telecom data, alternative data, or any other dataset that has info about locations, Placekey's free universal location identifier is a godsend. Now, your clients can easily join your datasets to other datasets including their own first-party data, decreasing onboarding time, and driving revenue. Read our case study to learn more.
