This is a discussion about the submission for postcodes / fr.
The Base Adresse Nationale (National Adress Base) is launched in April 2015. It’s a partnership between IGN (National Institute of Geographic and Forest Information), La Poste (national postal service), OpenStreetMap France, Etalab (Prime Minister’s Office for Public Data Openness and Open Government) and the Direction générale des Finances publiques (General Directorate of Public Finance).
It is available here: https://adresse.data.gouv.fr/
This base is one of the 9 datasets of the Public data service established by the article 14 of the loi pour une République numérique (law for a digital republic).
The license is Licence Ouverte / Open Licence (the license of the French government) which is obviously an open license.
