This namespace prefix complements the primary addr:*=* keys, and appears to being used to indicate additional official address information of a feature.
Generally, only addr2:street=* and addr2:housenumber=* are used. If there are only multiple house numbers, addr:housenumber=* can be sufficient.
For an example with addresses in 2 countries: Hôtel Arbez needing addr2:country=*, addr2:city=*, addr2:postalcode=*
The tags are not supported by Nominatim (status Jan 2026).
Several but separate Wiki pages outlining a draft to formalize this namespace tag were found:
