postcodes, should they be removed from the import? Is there a

There is a database, but one of OSM UK's big bug bears is that it is
not licensed in a way that allows it to be used for OSM. About the
limit of what you could do is find wrong postcodes, and then use other
means to correct them. I think removing a postcode on a mismatch
might be too close to using the data.
I'm, of course, referring to Royal Mail's Postal Address File (PAF).
There is a list of GB postcodes (not Northern Ireland) which, being OGL,
is compatible with the OSM licence. I maintain an overlay of postcodes
using that data, which you can see more about here:
https://raggedred.net/codepoint/
I am, of course, referring to the dataset Codepoint Open, supplied from
Royal Mail and distributed on the Ordnance Survey open data page.
https://www.ordnancesurvey.co.uk/opendatadownload/products.html
There is a version also supplied by the Office of National Statistics
which is based on Codepoint Open, but with some extra information for
each postcode. This also contains expired postcodes too.
Both of these datasets do not show each delivery point, but just a
centroid (in OSGB grid ref) for all the delivery points.
