I believe this is relevant to how governments manage cadastre. For example when 2 old areas are united (owned by single person instead of 2) then you have to deal with duplicate addresses. Similar to buildings, when you have 1 single apartment building instead of 5-10 houses, you need to do something with their addresses. Thats why In the middle of the street you may find address 13/17. But at street corners this is different story. Sometimes we use double addresses, sometimes not. I have idea why it is so.</span></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">Actually, try too hard to find any logic here, this is insane: <a href="http://taginfo.openstreetmap.org/search?q=addr4">http://taginfo.openstreetmap.org/search?q=addr4</a>: </span><span style="font-size:12.8000001907349px">We don't have cadastre logs or anything actually (only pictures of signs).

The images on the proposal page server do document that they exist. But pulling out a list from OSM doesn't explain why they exist. They could as just as easily be missed tagged. Can you describe the root cause of why these structures ended up with two addresses? Conscription is one example. However addr:conscriptionnumber is already in use. </div><div class="gmail_extra"><br></div><div class="gmail_extra">What I'm trying to understand is why is addrN the solution.
