French Address Search

About French Address Search

The geocoding service run by France's Géoplateforme (formerly the Base Adresse Nationale API Adresse, which is being decommissioned at the end of January 2026) provides address search and coordinate lookup for the French national address database. It supports direct geocoding, converting a postal address, place name, or cadastral parcel into geographic coordinates from an HTTP request, and reverse geocoding, returning the nearest matching addresses, place names, cadastral parcels, or administrative units from one or more latitude/longitude points. Both types of geocoding are available as single calls or batched through CSV file uploads, with a separate CSV geocoding tool provided on the site. The underlying data is refreshed from the Base Adresse Nationale twice a week.

The service is aimed at developers and organizations needing to integrate French address search or reverse geocoding into scripts or applications, including public-sector actors. It enforces a rate limit of 50 requests per second per IP, returning an HTTP 429 with a retry-after header (starting at 5 seconds) when exceeded; public-sector users with service-public missions can request an exemption from this limit, and anyone can alternatively self-host the service using a Docker instance loaded with BAN data, though self-hosted deployments fall outside IGN's supported scope.
