That's the case outside the UK as. Look up any address in Flanders and
you get Flanders somewhere in the address stack. This admin level is
never used on letters nor in navigation, only for administrative
purposes.

A lookup on DA10 1AZ gives the following results:
Marstons Inn (for example)
Talbot Lane
Weldon
Ebbsfleet Valley
SWANSCOMBE
DA10 1AZ
So it has a building name, a street name (Talbot Lane), a locality
(Ebbsfleet Valley), a sublocality (Weldon) and a post town (Swanscombe).

Not according to Royal Mail ;) But then that is no proof either, except
that is where post will be delivered by them.

Hi,
Yes, I was talking about in OSM, so was reluctant to go looking up the RM
version. When I used to sell stuff I did check with the RM website before
sending stuff out. In my local area I know which postcodes are for which
post town so I can correct without referring to the RM.
For delivery,
Haha, fair enough, it must depend where you live and the purposes for
needing an address. I apologise for the digression.

Occasionally, especially with businesses, extra 'bits' get added to make
their establishment appear posher than it actually is.
Looking at it's location you can see why. 'Next to the interchange'
won't entice many customers.

AFAIK, Nominatim does not try to generate an address you can put an a
letter. It tries to show the address as part of the administrative
hierarchy defined by the other objects in OSM. Some of those
administrative levels are not
In the UK, this algorithm is useless if you expect to get the actual

We have to remember that in the UK there is only a tenuous link between
the postal address and the physical address. A building can have
multiple postcodes, and the road/place in the postal address may not be
the same as the road/place you might expect from looking at the "nearest
road" and admin
Maybe it is interesting to repeat how Nominatim resolves addresses,
just in case someone wants to do a search after adding an address.
- Nominatim starts from an address point (or building way with
address). It takes the house number from it and the street name.
- It tries to match the street

Hi Robert,
You might be able to give the '1AA's special treatment as I believe they
are reserved for the local postal sorting office. So, BN1 1AA is the main
