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.
