    <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>

          <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>
