I agree. But, where multiple UPRNs are co-located with a single building, there's no consistent way to tell from the Open UPRN data which UPRN attaches to which subdivision. The open data has no z-index, so where you have a flat above a shop, for example, the data will give you two UPRNs for the same building but no indication of which is the flat and which is the shop. For that, you need local knowledge - and it can't be local knowledge obtained from incompatible sources. So there won't be any easy way to look it up, as all the lookups are likely to be based on data obtained from MasterMap and AddressBase.

Re: [Talk-GB] UPRN & USRN Tagging
I believe that the French have been using the country namespace in ref codes recently and, although I was initially doubtful, I now see the value in not claiming a reference code for the entire world. Some examples in https://wiki.openstreetmap.org/wiki/France/Liste_des_r%C3%A9f%C3%A9rences_nationales Sure, USRNs must have already been added a while back from the UK National Address Gazetteer or something, but that doesn't make ref:usrn right and fair to other countries that may have a different meaning for the acronym.

Re: [Talk-GB] UPRN & USRN Tagging
Hi Mike I tend to agree in terms of consistency. Looking at the results for https://taginfo.openstreetmap.org/search?q=usrn - the key 'ref:usrn' dominates so to me makes sense to use 'key:uprn'. Searching on UPRN reveals the lack of clarity.

Re: [Talk-GB] UPRN & USRN Tagging
Which makes it difficult to know or guess what the a tag relates to without research, especially if used wrongly or without consultation. Tags should be self-descriptive to the extent possible. Sorry, parochialism just gets up my nose! :-) Definite thumbs up up to using an ISO country code if nationally specific. Encourages good practice for all.

Re: [Talk-GB] UPRN & USRN Tagging
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. -- Andrew From: Tony OSM Sent: 03 July 2020 15:31 To: talk-gb@openstreetmap.org Subject: [Talk-GB] UPRN & USRN Tagging As we have access to the data and Robert Whittaker has produced a great UPRN locations map, how are we planning to tag OSM objects? ref:UK:uprn and ref:UK:usrn have been suggested as tags - I think this is the way to go. 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 ___ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb

Re: [Talk-GB] UPRN & USRN Tagging
Agree with ref:GB:uprn and ref:GB:usrn. Yes we do need to understand the data. If a usrn is given to a road, then the road is extended is the extension included in the original usrn or given a new usrn. Plenty of scope for decisions when using in OSM.

In addition to this, some streets appear to have a UPRN for the 'street record'.
