ONS postcode products are also OGL, so can be reused in OSM and similar.
They're also more useful than Code-Point Open in that they also include
lookups to a number of other government codes (such as local authority
GSS codes). It also differentiates between "large user" and normal
postcodes, and includes an introduction date and, where applicable, a
termination date for every valid postcode. And, unlike Code-Point Open,
the ONSPD has a persistent URL that can be used to automate updates.

More generally, the ONS open data geography datasets are a goldmine.
Another useful one is the Index of Place Names; that has obvious utility
for OSM as a means of verifying the official spelling of names entered
by mappers.
