If there are more than 19 UPRNs for the same building the reference will be longer than OSM’s tag value limit of 255 characters.

There is also Key:ref:NPLG:UPRN:1 in the wiki. Question: Should uprn be applied to the building outline or to a node? The OS data applies them as nodes, they are assigned by local authorities to a location as a node. The uprn is applied to many objects even bus shelters, and individual flats within a block; there may be what appear to be duplicates. I suggest that for OSM buildings or building parts which are individually linkable to a uprn then the uprn is assigned to the building way outline; otherwise to an OSM node if the mapper deems appropriate Tony Shield --- TonyS999
