Talk:Key:nohousenumber

Seems a useful qualifier tag where address information is only partially known to the mapper. For clarification, can it be assumed that if addr:housenumber is not assigned to the formal/official address but addr:housename is (as is the case with a lot of rural dwellings, especially isolated dwellings, in the UK) then nohousenumber= is unnecessary if addr:housename is specified in the address tagging? Equally, is there scope for a nohousename= formal tag also? --John Grubb (talk) 21:29, 12 June 2019 (UTC)

Whether or not the nohousenumber tag makes sense for you will depend on the local situation (are people expecting a housenumber when there is already a housename, etc). It’s hard to imagine a nohousename tag for me, as housenames unlike housenumbers are far from common, and their absence is what you would expect.—Dieterdreist (talk) 23:16, 12 June 2019 (UTC)

Is it fine to use it when address is altogether not present?

For example lets imagine building=house that has no address at all. Is it incorrect to use nohousenumber=yes on it?

I propose to state "For explicitly stating that no house number is assigned to a place." like it already does in short infobox description Mateusz Konieczny (talk) 08:35, 13 August 2025 (UTC)

Whether the object simply does not have an assigned nohousenumber or no address at all, I consider that in both cases there is no housenumber and therefore this tag is fine (even if it is insufficient to describe that it has no other part of the address in countries where this exists) but only if you have a source that the number is not assigned.

The problem is that by survey, user has no way of knowing whether this object has a housenumber or not; all they can see is the absence of a sign. And therefore, I think that using this tag in SC is a bad idea.

I myself survey more than a hundred houses without signs, which with SC would have led to the incorrect use of this tag.

And when checking the items entered by SC, there is a 100% error rate.

For ex https://www.openstreetmap.org/way/216420880 is a unsigned addr:housenumber=13a and not nohousenumber=yes

I therefore believe that SC should never have suggested this tag, in neither of the two situations mentioned in the GitHub ticket, and should have simply added a tag describing the absence of the sign. Another source is needed to determine whether the absence of a sign means that there is no house number.

IMO nohousenumber=yes simply denotes what the tag says - "no housenumber", and not "no housenumber, but there's an address". I.e. it does neither imply that there is an address nor rule it out. After all, *if* this is a house without a housenumber but still an address, that can be expressed with nohousenumber=yes + addr:street=Backwoods Drive + addr:city=Lonesome Town + ...

What is “an address”? Are free form descriptions about a position an address? address:full suggests so. No address at all can hardly happen. This said, I would use nohousenumber only for cases where a housenumber could be expected, the typical situation are places who explicitly state that there is no housenumber, it is not uncommon in Italy (“snc”) although it is illegal (municipalities must assign housenumbers, legally, just that they don’t always do it). —Dieterdreist (talk) 10:57, 20 August 2025 (UTC)

Meaning of values "separate" and "shared"

Can anyone explain, what the values "separate" (1847x) and "shared" (469x) stand for? The rest of the values found by taginfo seem to be useless and nonsense to me, but these two may have semantics that could be useful. --Stephan t (talk) 14:28, 11 December 2025 (UTC)

In Hong Kong, most newer buildings don't get uniquely numbered individually. The entire estate gets one addr:housenumber=* , which is duplicated on all building=apartments inside.
I have changed to addr=* in the sense of addr=main
