PAF® is a database of all UK addresses and postcodes. PAF® is used widely for the efficient delivery of mail and, increasingly, for online use particularly for address look-up, address verification, and in mapping software. We hope you can find all of the information you need about raw data and PAF® powered software solutions, however, if you have any questions please feel free to Contact Us.
Product information
PAF® contains:
29 million business and residential addresses to which mail can be delivered
1.8 million UK postcodes
1.4 million business names
Small User Residential, Small User Organisation and Large User Organisation details
records for England, Scotland, Wales, Northern Ireland, Jersey, Guernsey and the Isle of Man
Please note: PAF® doesn’t include any address details for the Republic of Ireland or for addresses that are unable to receive mail such as telephone exchanges and electricity sub-stations. Also, since PAF® is a database of delivery points you won’t find the names of private individuals, except when it is the only method of identifying a Delivery Point.
PAF® product options There are two PAF® options available – Full PAF® or Part PAF®. A Full PAF® record comprises all known delivery address and postcode elements in the UK, whereas a Part PAF® record includes some of the same elements but not all. We have created a PDF to show the different data elements that are included in Full PAF® and Part PAF®:
Maintaining the quality of PAF® PAF® users value and depend upon the accuracy of the data we provide. Maintaining the accuracy of the data is the Address Management Unit’s number one priority. Royal Mail’s 65,000 postmen and women capture thousands of address changes every day that we use to continuously update PAF®. If you purchase PAF® raw data from Royal Mail you can:
take a complete edition of PAF® monthly, quarterly, bi-annually or annually
take a complete edition of PAF® followed by daily updates, monthly updates or quarterly updates
take updates only if you already have a complete edition of PAF®
Customers looking to buy a PAF® solution from a Solutions Provider should ask about the regularity with which PAF® is updated.

Technical information
File formats
Royal Mail supplies PAF® as raw data. There are three different PAF® files available:
1. Main File:
The master database Main File contains complete Postcode and address information for over 29 million UK addresses. Main File contains no software and the raw data within it must be processed for use through IT applications.
2. Compressed Standard File:
An expanded form of the Main File with over 29 million UK addresses in sequential order, as well as Delivery Point Suffix data.
3. Ranges File:
A similar format to the Compressed Standard File, it takes up less space by ranging numbered properties on the same Postcode together in one record.
Address format The addresses held on PAF® are in a relational format, i.e. they are held as a series of alpha-numeric keys, or pointers, which relate to supporting files of Address element text rather than text. The supporting text files are:
Localities File
Thoroughfares File
Thoroughfare Descriptor File
Building Names File
Sub Building Names File
Organisations File
Each address on PAF® has an eight-digit number associated with it – the Address Key. This number in conjunction with the Organisation Key and Postcode Type identifies the address.

Licensing & licence fees
Fees for licensing the use of PAF®:
You have two options; if you want to programme the data, you can license the data from Royal Mail and you will be responsible for returning the appropriate fees to us directly. Alternatively, you can license software that contains PAF® from a licensed Solutions Provider. Most customers choose this option. If you license through a Solutions Provider they will return fees to Royal Mail on your behalf.
The table below shows the fees that either you or your Solutions Provider will return to Royal Mail. As you can see, you can license PAF® for use within your organisation – internal use – or for use on your website – external use. Depending on the volume of use and number of users, you can choose to license on a transaction ‘pay as you go’ basis or on a user basis.
You can also license PAF® on a Postcode Area basis. This costs £2 per Postcode Area.
