Information on administrative geographies can be found in the downloads, and in the Beginner's Guide section of the website.
Names and codes files are in CSV format, with accompanying metadata in HTML format. CSV files can be read in MS Excel format and all common database applications, HTML files can be displayed in any internet browser. The files all contain the new nine character coding as well as the old style coding. For further information please see the Code History Database. Please note that Northern Ireland has not adopted the nine character coding at present, so any information will still be in the current style coding.
Files can be downloaded free of charge.
