I’m often the person who fixes those. I check the Nominatim QA tool regularly for Europe. In UK and Nederlands spaces and uppercasing are the most common mistakes users make. Compared to missing a digit, having one digit too much, 0 vs O, or putting house numbers or city name in the postcode field.
For a small area, here it’s one neighborhood, I usually use a Overpass API plus level0 editor.
-
overpass turbo Ideally with the exact (wrong) postcode but in this case it’s multiple so I’d query all
-
Click on ‘Data’ instead of ‘Map’ shows the relevant objects. But it’s not formatted nicely. I change the
[out:json]in the query to[out:csv(::type,::id)]and run it again -
Now I see a list
@type @id
way 161881012
way 161881013
way 712133694
way 712133695
way 712133696
way 712133697
way 712133698
- Using my favorite editor I change the list into a comma separated one line
w161881012,w161881013,w712133694,w712133695,w712133696,w712133697,w712133698
- Open the level0 editor http://level0.osmz.ru/ , login and add it to query field, click 'add to editor`
- now I make the changes relatively fast
In total this takes me about 5 minutes because I’ve used those tools for years. I’m not doing the steps now in case you want to try them.
Like I said I regularly cleanup European postcodes so eventually I would encounter the Lymington ones again.
