As approved distributors and value added resellers, we have created this subset data file using Royal Mail and Ordnance Survey source files and have simplified their RAW data to such an extent that we are able to offer sub sets of their files cheaper than if your ordered direct.

Postcode Applications

The Royal Mail Postcodes data is ideal for validating Postcode relating information to ensure Postcodes are current and accurate.

The Royal Mail Postcodes data covers the United Kingdom.

Supply Format

The data is supplied as a Comma Separated Variable (CSV) delimited text file using double quotes by default. This field format will open very easily using almost any software application including but not limited to Excel, Word, Notepad, Access, SQL etc.  Due to the size of the file, older versions of Excel may not be an option as Excel limits any file size to around 65,000 rows / records.


The data is by default emailed at the time of order using a secure download link delivery method. If you require the data supplied in another format then we will be more than happy to accommodate you where reasonable to do so at no extra cost.
