French Address Search

API

Free French address search API by the French Government

Overview

The French Address Search API (from geo.api.gouv.fr) offers RESTful endpoints for forward geocoding (address text to coordinates) and reverse geocoding (coordinates to address). Key endpoints include /search (with query params like q for address queries and limit for result count) and /reverse (using lat/lon). Responses are JSON-formatted, containing official address details (street name, postal code, commune, latitude/longitude). Use cases include autocomplete in forms, validating delivery addresses, integrating geolocation in logistics apps, and mapping French locations for urban planning or tourism platforms.

Example Integration (JavaScript)

script.js JS


fetch('https://geo.api.gouv.fr/adresse')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
