Like a lot of peopl开发者_运维技巧e I would like the Post Office PAF file for Postcode to Address data. What I have at the minute is the Postcode to O/S coordinates file. Are there any solutions for getting this type of data ? Could I rip any credible data from a sat nav postcode file ?

The source which I use is Yahoo Geo Planet.

You can download the entire GeoPlanet Data file which comes in TSV format. When I downloaded it I just imported it to mysql using mysqlimport.

It contains a record for every distinct geographically location in the world. A tonne of post codes, (pretty much every code I have needed for UK). All you would need to do is only use records with are of place_type zip.

For New Zealand data, your best bet is to use the official NZ Post’s Postal Address File (PAF) and Land Information New Zealand (LINZ) for street address files with latitude and longitude geo coordinates. If you prefer programming with SOAP or REST APIs then an Address Finder Search API combined with the Geocode Address API would help for bulk reverse lookups.
