Postcodes of metropolitan France

Updated and updated shapefile layer compared to the starting layer from OpenStreetMap in 2024. The update incorporates the absent sub-municipal divisions and updates those affected by the creation of new municipalities since 2016 (OUR Law) Occurrences in the 'Achvmt' field: 'Validated': no changes 'Validé - arrondissement': postal codes (CP) based on the arrondissements for Paris, Lyon and Marseille. 'Validated infra-municipal division': all municipalities that are covered by at least two CPs. Traditionally, sub-municipal divisions are common in large cities, but they also exist in more rural municipalities today as a result of recent municipal mergers. In this case either the extension of the CPs remains unchanged or the CPs are modified. ‘Validated change’: Changes in the municipal grid sometimes lead to changes in the boundaries of the CPs. These changes are based on the OSM limits or the IGN . municipal base It should be noted that, as a result of the mergers of municipalities, two CPs have virtually disappeared: 54790 Mancieulles (new municipality 54150 Val-de-Briey) and 63111 Dallet (new municipality 63115 Mur-sur-Allier). The 'Note' field describes the types of updates. The data sources, used in the course of 2025, given that none is 100% reliable and that the inhabitants’ old practices can continue: <https://www.code-postal.com> <https://postcodes.cybo.com> Google Map National address base: <https://address.data.gouv.fr/data/ban/addresses/latest/csv> Address points mapped according to their postal code make it possible to delimit the infra-urban perimeters. However, many CP areas are not homogeneous and a municipality or neighbourhood may have two CPs. The choice is often made to allocate either CP depending on the sources mentioned above and the original version of the background map. The topology of the polygons is checked: no overlays or holes between polygons.
