Match Postcodes to Counties
The Postcode to County lookup database contains every Postcode in the UK (including retired Postcodes which are no longer in use) and the traditional county, administrative county and ceremonial county each Postcode falls within.
The fact that there a different 'types' of counties causes great confusion and this database seeks to provide a solution to all requirements by offering the three varieties of county geography for each Postcode in the UK.
You can read more about how this confusion arose and what it means at the County-Wise website >
Planning & Addressing by County
This data allows any UK address record to be matched to it's corresponding administrative, traditional or ceremonial county for use in business planning and administration. In addition, as Royal Mail no longer require County names in addresses and therefore don't include them in their PAF (Postcode Address File) product, this file can be used to supplement address records with their associated County reference.
The database is available in a variety of formats including CSV text, Excel 2007+ or Access formats and contain the following fields of information:
- Traditional County
- Administrative County
- Ceremonial County
