From FAQ on NINIS website:
Can I obtain a copy of the lookup table which links postcodes to geographic areas?
Yes - The Northern Ireland Central Postcode Directory (CPD) lists all postcodes and the geographic areas they are allocated to. The CPD is available for download in either Access 2000 or Text file (dollar ($) separated variables) format from the NISRA website. However, users must sign and return the Terms and Conditions document available here to receive a password for access to download CPD from the NISRA website.
