Revision: you need to fill a form to get access to this dataset. Then you get a link by email.

Open postcode data which meets the specification here (postcodes and corresponding geospatial locations - lat/long or equivalent) is available via the Ordnance Survey's Code-Point Open dataset, which contains the 1.4m GB post codes each with a UK national grid reference of the postcode's location in eastings and northings (convertable to lat/long by published formulae) and with the administrative area (country/county/district/ward, plus National Health Service Region and Authority) in which it is located. This is updated quarterly. Similar Postcode data for the devolved province of Northern Ireland is not available as Open Data. The main UK address database (~24m individual addresses) is confusing called the Postcode Address File. This is a subscription-only database privately owned by the Royal Mail. The Open Data User Group have been pressing for its release too - see The Postcode data as of August 2014 is available here: The geographic coverage is United Kingdom (including Northern Ireland).
