But Ebbsfleet is not a Post Town. The address will include Swanscombe. I
should have said before that my experience (as an eBay seller) is lots of
people are unaware of their correct postal address. Each postcode section
eg. DA1, DA2, DA3... will have a particular post town, so I correct this
which I know to be wrong for the postcode. Because several of the editors
don't include a box for suburb or hamlet it is aslo common to see names of
villages or suburbs in the tagged as addr:city.

Colin made a couple of great points. A postcode so far as it exists is
really just an attribute applied to various delivery points. Despite
postcode polygons sometimes being used, they are really just automatically
calculated from the delivery points to which the postcode applies.

Colin was also right to draw a distinction between postal addresses and
administrative areas in the UK.  To my mind Nominatim should use postal
addresses where tagged in OSM rather than trying to interpolate a address
from admin boundaries. As a backup it is better than nothing but it
prodcues some bizarre results. Somebody might live in Blackburn or Darwen,
but they don't live in Blackburn with Darwen
