You can find information on administrative geographies in the ‘Beginner's Guide to UK Geography’ section of the website and you can download the files from the Open Geography portal.
We provide names and codes files in CSV format, with accompanying metadata in XML format, product specification document and any other relevant documentation. CSV files can be read in MS Excel format and all common database applications; XML files can be displayed in any internet browser.
The files all contain the nine-character GSS codes. For further information, please see the Code History Database. Please note that Northern Ireland has not adopted the nine-character GSS codes for all geographies at present, so most information will still be in the old-style coding.
You can download the files free of charge from the Open Geography portal.
