Geocoding API for France: GDPR-compliant EU hosting

Geocoding in France presents unique challenges, particularly due to the complexity of address formats and the diversity between urban and rural areas. French addresses typically consist of a house number followed by a street name, a postal code, and a city (e.g. 15 rue de Rivoli, 75001 Paris). While urban centers like Paris, Lyon, Marseille, and Bordeaux enjoy excellent coverage from OpenStreetMap, rural regions may experience some inconsistencies. Moreover, compliance with the stringent CNIL regulations makes data sovereignty a top concern for French developers.

Geocoding coverage in France

When it comes to geocoding coverage, Mapsi leverages OpenStreetMap (OSM) data, which offers very good quality throughout France. In urban areas such as Paris, the data quality is excellent, allowing for precise geolocation and addressing. However, it's important to note that rural areas may see some coverage gaps, especially in newer developments. The inclusion of France's Base Adresse Nationale (National Address Database) provides a supplementary layer of addressing information that further enhances the accuracy and reliability of geocoding in these less populated regions. This focus on quality differentiates Mapsi from other providers, as developers can rely on up-to-date and comprehensive addressing data.

Address formats and geocoding accuracy

French addresses follow a specific format: house number + street name, then postcode + city. A typical address might look like “15 rue de Rivoli, 75001 Paris.” Developers using Mapsi need to be aware that apartment or étage information is often provided in a separate field and is not part of the geocodeable address. The Mapsi API handles this address structure effectively, ensuring accurate geocoding while allowing room for specifying additional address details when necessary.

GDPR and data residency

With Mapsi hosted on Hetzner servers in the EU, all geocoding requests and results remain within the European Union, aligning perfectly with GDPR requirements. For applications that handle personal data—such as delivery addresses and user locations—this provides a significant advantage by reducing the compliance overhead associated with data residency. Unlike some US-based providers, where data may be processed outside of the EU, Mapsi ensures that data sovereignty and user privacy are maintained, fulfilling the CNIL's strict regulations.

Latency from France

For developers in France, you can expect sub-40ms latency when querying the Mapsi API thanks to Hetzner’s infrastructure in Frankfurt. This performance ensures that your applications can provide seamless geolocation services without noticeable delays.

Getting started: geocoding a France address

Getting started with the Mapsi geocoding API is straightforward. Here's a curl example for geocoding a typical Paris address:

curl -X GET "https://api.mapsi.dev/geocode?address=15+rue+de+Rivoli,+75001+Paris&country=FR"

This request will return geolocation data for the specified address, simplifying the integration into your application.
