Royal Mail has recently introduced the ‘Unique Delivery Point Reference Number’ or UDPRN to every Delivery Point on PAF. It is a simple and unique 8 character reference number that can be used to identify a single address. This optional data is supplied free of charge to all Mainfile or Compressed Standard File customers (no Ranges version is available) who require it.

Please click here for UDPRN Technical information.

PAF is available on two different file formats; CD-ROM and Internet Download (Changes only).

• Main File: The PAF Main File is a relational raw data product (this means that it contains grouped or related address data, as well as Mailsort codes and Delivery Point Suffix data)  It is the master database containing complete Postcode and address information for over 28 million UK addresses.  Main File contains no software and the raw data within it must be processed for use within IT applications. 
• Compressed Standard File: An expanded form of the Main File with approximately 28 million addresses in sequential order, as well as Delivery Point Suffix data
• Ranges File: A similar format to the Compressed Standard File, but takes up less space by ranging numbered properties on the same Postcode together in one record.
  

For more in-depth technical information on all raw data products please see the "PAF User Guide" below.
