Adjacent postboxes
Do 2 adjacent postboxes receive the same UPRN? See PO30 1371 https://www.openstreetmap.org/node/580181955 and PO30 1372 https://www.openstreetmap.org/node/738107215 Jnicho02 (talk) 10:19, 18 November 2020 (UTC)
- As with everything in this, the answer isn't clear, and is hard/impossible to verify. As a UPRN is a plot of land, the obvious answer is, yes, if 2 are on the same plot of land they could share a UPRN. I think the real answer is is depends, it depends on the land ownership and it depends on the council that allocated the UPRN. Also as a note it's entirely possible for a post box not to have its own UPRN. See this where the post boxes are presumably part of the delivery office, which presumably has the UPRN of 10094233486.
- Knowing what I know now, I wouldn't have added that UPRN, the area is to dense to de anonymise the UPRN. I'm happy for it to be removed. --CjMalone (talk) 12:18, 18 November 2020 (UTC)
- Only just seen this query. Certainly in Nottingham (where i've added UPRNs to every postbox which I could reasonably identify), boxes close together have a single UPRN even if not mounted on the same support, and this includes normal pillar boxes & metered mail/parcel ones.

Good or bad?
I'm planning on adding a section about the way that UPRNs are being used to simplify UK property transactions via Dept for Housing and Levelling Up + Geospatial Commission. My fear is that strongly encouraging local authorities to publish Open Data keyed on UPRN could lead to data being published without geometries and hence be locked in to OS Mastermap....and require payments to OS (from Govt via PSMA and private business via licencing).

Historical/Discontinued UPRNs
Where there are multiple UPRNs at a location, some of them might be historical. Possibly a house split into 2 flats has been merged back into a single property. In this case, are we sure that the mapping advice should encourage the addition of multiple UPRNs? The only way I know of to check is via https://www.findmyaddress.co.uk/search which is probably not a legit source (although, can they really restrict that knowledge!?).

- Definitely not a usable source. They consciously want that data private, and have fought to keep it so. CjMalone (talk) 14:15, 23 January 2026 (UTC)
- I vote to encourage the addition of UPRNs only when we are reasonably confidant we know what it is, not blindly adding all of them. CjMalone (talk) 14:15, 23 January 2026 (UTC)
Parent and child UPRNs on apartment blocks
Just read in an article that, "In flats or offices, the block takes a parent UPRN and then each flat or office has its own child UPRN."
