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.

Firstly, addr in OSM is generally postal, not geographical.  As 
indicated elsewhere containment (or is_in) define the geographical place.

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.

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.)

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