As I understand it, postal_code, in a UK context is for the outbound
code, only, and is most useful in certain cities, where street name have
the outbound code appended, on the name sign.
On the other hand, sticking the full post code on a road is wrong,
because it implies that everything on that road has that post code,
which is not necessarily true, even for short roads, if there is a big
user.
For bigger roads, odd and even numbers may have different codes, and you
cannot normally split the road at the right place without doing a house
to house survey of the codes.
UK post codes are based on the postmans walk, so follow the footpaths
that a postman can follow to deliver mail. Yes a street may have a
different postcode on each side, and long roads are broken down into
smaller blocks each with it's own postcode. One rule for postcodes is
that each will only cover one primary street name and so ignoring the
'postal address file', postcodes ARE essentially a list of streets.
Two new estates are going up either side of here and both currently have
plot numbers for selling the houses, but they will be replaced with new
road names and house numbers which the council will allocate, and then
the post office will add new postcodes to those new road names.
All that is left to be sorted out is should all the current
addr:postcode entries logged against the street ways be replaced with
postal_code ... that should probably have been used originally, bu this
material is ONLY relevant to the addr: group of tags ... except most sat
nav's these days understand a postcode better than a street name.
