<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>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>
