<p>The 'shell' of the building is not normally addressable so it
would not have a postcode allocated. I guess this has occured as
postcode areas normally would cover up to 100 properties. I note
that the response in the discussion seems to have come from a
councillor at Peterborough City Council so I assume he has checked
with the GIS team. <br>
Not elegant but perhaps use somethinig like addr2:postcode= (this
has been used rarely e.g. <a moz-do-not-send="true"
href="https://www.openstreetmap.org/way/128457240">https://www.openstreetmap.org/way/128457240</a>)<br>

<div>Hi Colin, Hi BD, </div>
<div> </div>
<div>as I live in a country with the maximum "anomality" are
different 5-digit postcodes along a street (or sides of said
street) I find different codes per building strange to say to
least. </div>
<div> </div>
<div>I'd go for: </div>
<div>* Remove addr:postcode= from the building's area and add a
note=This building has two postcodes, X and Y </div>
<div>* Add two new nodes within the area of the building (not
connecting to the area), add all addr:*= with the respective
postcodes and add a note=This building (link to way/area of
building) has two postcodes, this node is for levels A thru B.</div>
<div>* Change the Note in the area to display the links to the
Postcode Nodes.</div>
<div> </div>

<div>I would recommend leaving this to UK mappers who understand
the UK postcode system.... Postcodes don't indicate buildings in
the UK - they indicate postal delivery points. Don't try and
find logic where none exists...</div>
<div> </div>
<div>The relationship is n:m. You cannot ask "what is the postcode
for this building" - you have to ask "what postcodes have a
delivery point in this building". You cannot ask "which building
does this postcode indicate", you have to ask "which buildings
have a delivery point with this postcode."</div>
