A database of postcodes/zipcodes and the corresponding spatial locations in terms of a latitude and a longitude (or similar coordinates in an openly published national coordinate system). If a postcode/zipcode system does not exist in the country, please submit a dataset of administrative borders. Data submitted in this category must satisfy the following minimum conditions

  • Zipcodes
  • Address
  • Coordinate (latitude longitude)
  • national level
  • updated once a year

  • Administrative boundaries

  • Boarders poligone
  • name of poligone (city, neighborhood)
  • national level
  • updated once a year

Data Location




The national address database (BAN) fulfills the requirements to a larger extent as it gives coordinates for all addresses including their zipcodes. It exists in two versions of the base and the first one is the one that is taken into account in this submission (and not in the previous one). We believe this BAN ODBL version can be accepted as an official source because:


The previously registered "Base officielle des codes postaux" by La Poste https://www.data.gouv.fr/fr/datasets/base-officielle-des-codes-postaux/ does not match the new requirements as it only provides openly an association of zipcodes with ciies. Some cities have multiple zipcodes, so even by associating the data with the opened administrative borders database GEOFLA https://professionnels.ign.fr/geofla, we would not be able to get coordinates corresponding to zipcodes.

Although another database could fulfill the requirements to a larger extant : the national address database BAN that gives coordinates for all addresses including their zipcodes. Unfortunately it exists under two different versions:

The latter dataset named "Base Adresse Nationale" requires registration for direct download and is supplied after form registration under a closed license (see https://www.savoirscom1.info/2015/04/ouverture-de-la-base-dadresses-nationale-ban-la-fete-gachee-par-une-licence-piege/ for a complete legal analysis).

Reviewer comments

Reviewing the location theme for France was not an easy task due to the intricate situation created by the existence of 2 official datasets, one belonging to the National Post and one created in collaboration with other gov departments and with OpenStreetMap France. One significant difference that we need to point out to is the different licensing of the 2: the dataset build in collaboration with OSM has a ODbL license, and the other one has a specific license. The latter is a restrictive proprietary license (https://adresse.data.gouv.fr/static/pdf/BAN%20Licence%20de%20repartage.pdf). An analysis made by the civil society can be found here (https://www.savoirscom1.info/2015/04/ouverture-de-la-base-dadresses-nationale-ban-la-fete-gachee-par-une-licence-piege/).
It clearly shows a situation that has the potential to generate a multitude of legal, but not only, issues that could significantly hider the access to the reuse of this information. The index has been constructed taking into account the various issues that arise from the mentioned situation, from license, to quality of data, from coverage to the entities and their official role in building this dataset. We would also like to mention that we recognize the high quality of the dataset built in collaboration with OpenStreetMap and that we applaud this open-mindedness. However, for this wonderful initiative to be truly productive and without a doubt a pillar in the base data of France, we consider that significant steps must be made in the direction of dissolving this complicated situation.
