I reverted this changeset now. Still not sure how to solve it.

It's more related to universities which have many buildings across a larger area. There is a discussion in https://github.com/osm-search/Nominatim/discussions/3418#discussioncomment-9379380 (where I argue the same: there's already a boundary=site in another relation and this one should probably be a multipolygon again). I have no objection to revert.

For node/147621678, is "2112206" another type of identifier? It's not a postcode, those would be in the 523xx range around this area.

OSM relation/130935 already has the NUTS code PL9, and it's the same boundary. Is another relation really needed?

Can you review the postcode of this place? I think it's this business https://ratings.food.gov.uk/business/774466 (All data is from Food Hygiene Ratings Scheme Data is released under the Open Government Licence (v3) so afaik it's usable for OSM).

Hello. Can you explain why way/1238633639 has the URL of a another provider as the name? Is data copied from other map providers?

Can you review the postcode of way/294668651 again? On https://www.coop.se/butiker-erbjudanden/coop/coop-lesjofors/ clicking "Om butiken" I see the address is "Bergslagsgatan 70, 68260 Lesjöfors"
Of course they might have the wrong postcode on their website, that happens, too.

Great, I was just surprised because usually it would be many keystrokes. I'm looking after wrong data in addr:postcode and it came up in one of my reports. Happy mapping

What happened to node/11817888797 ? All values are empty (dots). Is that somewhat automated?

Is 2082900 a different kind of code? Postcode of nearby Cedar Rapids is in 55xxx range

I see you have the rare combination of speaking English, Turkish and Japanese. The "〒" sign in postcodes is only used in Japan. I have removed them today. Happy mapping, thanks you for your contributions.

Can you check the house number of the Southtown (West) shopping mall. On their website it lists a couple of shops within and from what I see the shops have house number 148.

For way/973025001 what does boundary=Emergency mean? It looks like the boundary of a neighborhood or suburb?

Thank a lot! The https://nominatim.org/qa/ tool uses "(LV-)?(dddd)" and I didn't notice the Lv->LV error. I checked with Overpass API now and indeed the whole country used the prefix, I'll get the regular expression updated.

I do like your verbose messages. A lot of OSM mappers just write "update" or "I created a place" which gets boring reading 100 times.

The restaurant's address in in India. The map shows the place in the United States. Are you sure you have local knowledge?

Thanks a lot! I've added the postcode now.

Hi Powdermilkman. Thank you for adding the address. Do you happen to know the correct postcode (zip code) for this building? 9844 has only 4 numbers, it should be 5.

Thanks for the feedback. I had a look of many noname tags around the world and it seems to be a common mistake. I'm working on a validator plugin for the iD editor to show a warning when both tags are set. It's not a fix but will make editing easier in the future.

I think the no_name tag is used wrong here. It's a common typo, should be noname. noname=yes It indicates a place definitely has no name instead of the name is unknown. Since a name:ar is present it has a name, doesn't it?
