<p>I maintain an overlay for editors [0] that show the CodePoint
Open centroids for GB. It needs updating. There are many, many
individual delivery points that have their own postcode, and many
delivery points that have a multiple postcodes too. Given that the
scheme for devising postcodes creates many different layouts I
think the idea of adding a postal_code to a section of road is
generally viable. It is common for one side of a road to have a
different post code from the opposite side of the same road. I
only add postcodes as part of an individual address
addr:postcode=xxxx xxx, where that can be determined from the
centroids.<br>

stretches of road.....is this an outdated artifact, or
something that people do and is useful?<br>

<br>
Unsure if this was national policy but in my area certain
organisations <br>
such as banks, medical centres & hotels were given unique
post codes, <br>
presumably due to the high volume of correspondence they'd
receive. Even <br>
though many of the properties have change businesses over the
years <br>
(especially banks becoming eateries) they still retain their
individual <br>
codes.<br>
<br>
If using the very undetailed code-point_open please don't
assume that a <br>
restaurant in a large building with unusually high ceilings
has the same <br>
code as it's neighbours. Local, on the round knowledge usurps
the database.<br>
<br>
