Free French address database with geocoding and reverse geocoding

Overview

adresse.data.gouv.fr offers RESTful endpoints for geocoding (address-to-coordinates) and reverse geocoding (coordinates-to-address) using France’s official address database. Key endpoints include /search (query addresses with filters like postal code or commune) and /reverse (retrieve address from latitude/longitude). Responses are JSON-formatted, including detailed address components (street, postal code, commune) and WGS84 coordinates. Ideal for logistics platforms, mapping apps, public administration tools, and e-commerce delivery optimization in France.
