About adresse.data.gouv.fr

adresse.data.gouv.fr is the official French government platform for the Base Adresse Nationale (BAN), a national address database maintained by the French Republic. It aims to reference every address in French territory and make that data usable by third parties, supporting use cases such as emergency services locating addresses, utility and telecom network connections, and cartographic analysis.

The platform provides tools and APIs for consuming this data, including a map explorer, an address certificate service, a geocoding service, a CSV geocoder, a BAL (Base Adresse Locale) validator and formatter, and a publication form. Data can also be downloaded for self-hosting. As of the page's reporting, 28,392 communes have updated their local address base.

The site also serves municipalities (communes) through the "Mes Adresses" application and related documentation, guiding them through auditing existing addresses, completing and harmonizing their local address base, and publishing it to the national database via one of five publication methods. It includes training resources such as online courses, videos, and technical documentation, and coordinates a partner community through a charter for organizations and communes that adopt the Base Adresse Locale format.
