Question: Can you recommend a service that helps with address and POI matching, deduping, and entity resolution using a standardized location identifier?

If you're looking for a service that helps with address and POI matching, deduping, and entity resolution using a standardized location identifier, Placekey is a great option. Placekey is a universal place identifier system that makes it easier to manage location data by giving you a single identifier for any address. The identifier, presented in the What@Where format, includes location name, street address, city, state, postal code, and country. It uses Uber's open-source H3 grid system for geospatial accuracy.

For a full location intelligence platform, you may also want to consider CARTO.

It includes native analysis and visualization tools on leading cloud platforms and has an intuitive drag-and-drop interface, more than 100 pre-built analysis components and access to more than 12,000 geospatial datasets. CARTO also supports scalable app development and is enterprise-ready with advanced security and authentication.
