|Tools for this tag|
To define a Facebook-Page or -Profile of an object. The value is the Page-/Profil-URL or the Pagename. In most cases, the full URL is used as value. It is also possible to add the user name or page name only (the part after the last '/'). This requires the user software to add the appropriate URL prefix, but it makes it easier to adapt to special needs like offering the mobile version of the page or a random language version.
It must be an official way of contacting.
The key facebook=* is in use as well, but less often.
How to use?
Assign this tag to any object (nodes, ways or relations):
As described above, both versions are valid. If you prefer to add the full URL, please make sure you link to the generic facebook.com page, use https, don't use any language-subdomains and remove all possible tracking tokens that might be shown in the address bar of your browser. Facebook itself is able to forward every user to their preferred version of the website (mobile, language), so there is no need to add a specific selection to OSM.
