- ref:FR:LaPoste=* - is used in France for the public post offices operated by La Poste, or shops and public amenities working under contract with La Poste.
- atm=yes - could be used if there is a automated teller machine present. However, if possible, you should try to place a separate amenity=atm node.
- change_machine=yes - could be used if there is a automated change machine present.
- amenity=vending_machine + vending=stamps - if possible, you should try to place in a separate node.
Potential data source
A list of postal public facilities has been released by the French Government initiative for Open Data. Locations indicated in this file seems to be the result of geocoding, and appear to be of variable quality (from very precise to obviously wrong). This is a very valuable input, but it cannot be imported without checking and comparisons from other sources.
However, most post offices have been mapped individually as these are well-known places in cities, and there are not many post offices (frequently not even one per municipality, except large cities that may have several). Most post offices in France are indicated by traffic direction signs; you can't really miss one (except possibly specific postal facilities for businesses or internal buildings for shipping/delivery only, not open to the public).
As many post offices in small villages are now closing, they are replaced by postal services hosted in local shops or other public services: they are more difficult to locate because these services are in other kinds of shops/services (e.g. in oil stations/garages, food shops, cafés, tobacco and newspaper/magazine sellers, ink cartridge sellers, mobile phone sellers, photography studios, hairdressers, or sometimes in the town hall of small villages...) and are no longer separate public amenities. You can use post_office:type=post_partner in that case. These postal "contact points" are serviced internally by another remote postal facility, not open to the public. All these points do not have a separate postal code (postal codes in France are assigned to central post offices for the final delivery to homes or to postal "contact points", and not necessarily to individual municipalities; specific "CEDEX" codes are also assigned to businesses with large volumes of incoming mails and needing special delivery independently of the actual location of the businesses using these special codes for mails sent to their internal business services). As a result, not all postal codes have their own "post office" amenity open to the public in their area of service (they only have one or more "contact points").
In January 2018, a long-running FOI and RoPSIR request by User:Rjw62 finally yielded a list of Post Office branches, complete with addresses, postcodes and opening times, that is available to be used in OSM under the Open Government Licence v3. Tools to help compare and improve the corresponding OSM data area available from https://osm.mathmos.net/postoffice/.
