<p>David, thanks for offering some updates.</p>
<p>By the way, I am not asking questions because I personally want the answers - I am fully aware of how these things work. And because of that, and because OSM tries to model reality, I believe we need some kind of anchor-point for our thinking in order to converge on a proper solution. In many countries postcodes/zip codes are associated with geographic areas; the UK, as frequently happens, uses a different paradigm. We need a clear statement of the intention for the addresses in OSM, and my belief is that they represent postal addresses as per the PAF. PO Box numbers are not applicable to OSM, as they cannot be related to a location useful in OSM. The discussion is just about Dependent Locaiity, Double Dependent Locality, and Dependent Thoroughfare. If we can define what OSM tag should be used for these three fields, we have a model which is sufficient for all UK addresses.</p>
<p>Of course, it is an option to decide to NOT represent this level of detail in OSM. In that case, expect mappers to make up their own solutions, and this discussion to resurface every few months.</p>
<p>Next iteration:</p>

<br> This is the one that actually normally causes questions. It is quite common to have named terraces, and to have runs of maisonettes numbered within a name.<br> <br>

<br> Firstly, addr in OSM is generally postal, not geographical. As indicated elsewhere containment (or is_in) define the geographical place.<br> <br> Secondly, in practice the only parts of the address you need are the detailed destination point code and the post code. However, I discovered that the postie on the beat also needs the street name to avoid having to look it up from the postcode.<br> <br> The bar codes for Walksort only contain the postcode and two character detailed destination. (Is there a potential project there, to capture these. Everyone who has received utility bills will have their own code, but they are only available to paying customers, as far as the sender is concerned.)<br> <br>

<br> PO Box is not really relevant. In most cases it is attached to a post office building.
