==Usage==
The "delivery points" held on the PAF are routing instructions used by Royal Mail staff to sort and deliver mail quickly and accurately. Elements of the address, including the post town and postcode, are occasionally subject to change, reflecting the operational structure of the postal delivery system. Each address is therefore not necessarily a geographically accurate description of where a property is located.<ref>{{cite web |url=http://www.postcomm.gov.uk/policy-and-consultations/consultations/postcode-address-file--changing-postal-addresses/PAFCodeofPracticeReviewFinalDoc.pdf |title=Ofcom &#124; Postal Services |publisher=PostcommGovernment of the United Kingdom |access-date=10 June 2013 |archive-url=https://web.archive.org/web/20070929010447/http://www.postcomm.gov.uk/policy-and-consultations/consultations/postcode-address-file--changing-postal-addresses/PAFCodeofPracticeReviewFinalDoc.pdf |archive-date=29 September 2007 |accessdateurl-status=2013dead |df=dmy-06-10all }}</ref> Buildings which contain internal flats or businesses but have only have one external front door, will only have those internal elements recorded in PAF if the Royal Mail have direct access to them using a key or fob.

Some versions of the PAF also contain the '' 'Delivery Point Suffix (DPS)' '' used in [[RM4SCC|CBC (Customer Bar Code)]]. Alternatively the DPS can be found using Royal Mail's '' 'Postcode Information File (PIF)' .''.<ref>{{cite web|title=Know how: a user’suser's manual for Mailsort®, Walksort®, Presstream®, Cleanmail®, Presstream® Walksort®, Royal Mail International Bulk Mail™ and Automated Standard Tariff Large Letter®|url=http://www.royalmail.com/sites/default/files/docs/pdf/Know%20How%202006%20PIP%20vs%201.6a%20Accepted%20Changes.pdf|publisherwork=Royal Mail|accessdateaccess-date=23 February 2016|page=80|date=April 2007|archive-url=https://web.archive.org/web/20160302020136/http://www.royalmail.com/sites/default/files/docs/pdf/Know%20How%202006%20PIP%20vs%201.6a%20Accepted%20Changes.pdf|archive-date=2 March 2016|url-status=dead|df=dmy-all}}</ref>
 
==Licensing==
Line 49 ⟶ 55:
On the other hand, an example of external use would be a company which provides a PAF-based address look-up on their customer facing website for their own customers to use when they order goods or services.
 
Royal Mail provide licensing advice on their [http://www.poweredbypaf.com/licensing-centre/public/ website].
 
==Public Sectorsector Licencelicence==
 
Public sector organisations can now use PAF under the public sector licence use terms. The current public sector licence was renewed in April 2023 and runs until 31 March 2028.<ref>[https://www.gov.uk/government/news/public-sector-access-to-royal-mail-postcode-address-file-agreed-to-2028 Public sector access to Royal Mail Postcode Address File agreed to 2028], Department for Science, Innovation and Technology and Geospatial Commission, published 20 April 2023, accessed 16 August 2023.</ref>
Public Sector Organisations can now apply to use PAF under the Public Sector Licence Use Terms. The Public Sector Licence will be fully implemented on 1 April 2015.
 
The 2023-2028 public sector licence covers England, Wales and Scotland, and was procured centrally by the Geospatial Commission so that usage is free at the point of use for delivery of vital public services by the UK government, devolved administrations, local authorities, emergency services, health services, and search and rescue organisations. The contract now also incorporates Royal Mail Not Yet Built and Multiple Residence data.
Royal Mail has worked along with the Department of Business, Innovation & Skills (BIS) & the Scottish Government to develop the Public Sector Licence. The Public Sector Licence is being centrally paid for by these organisations so individual public sector organisations will no longer need to return PAF licence fees to Royal Mail.

==Alias data==
 
The '''Alias"alias File'''file" is a supplementary file containing additional data which are not part of official postal addresses, including details that have changed over time, or have been amended by the public and then used. This file is used to identify these elements and [[cross-reference]] with the official postal address.
 
The Aliasalias Filefile holds four types of record: Localitylocality, Thoroughfarethoroughfare, Deliverydelivery Pointpoint Aliasalias, and Countycounty Aliasalias:
 
*The Localitylocality record - old short forms, local names, and 'postally-not-required' (PNR) details.
*The Thoroughfarethoroughfare record - contains replacement street and road names for a given locality, thoroughfare or dependent thoroughfare combination.
*The Deliverydelivery Pointpoint Aliasalias record - holds additional information at given addresses, such as trading names and building names.
*The Countycounty record - holds [[Counties of the United Kingdom|traditional]], [[Administrative county|administrative]] and [[Postal counties of the United Kingdom|postal county]] information.
 
Royal Mail, in their guide to the data products<ref>[ftp://ftp.royalmail.com/Downloads/public/ctf/rm/PAF_Digest_Dec_03.pdf PAF Digest]{{dead link|date=May 2025|bot=medic}}{{cbignore|bot=medic}}, p12</ref> imply that the county alias information was provided when Royal Mail removed the former postal county from the main file.
 
==Errors==
 
Royal Mail acknowledges that the PAF contains errors, and publishes forms for submitting error reports. A very small number of addresses are not listed correctly, and others (especially new developments) may not be listed at all for a period of time.
 
==Costs and public availability==
Between 2004 and 2006 a consultation was taken about the future management of the PAF. The proposal to release it for use at low or no cost was rejected, and the business model where it was used to raise money from profitable corporations was retained.<ref>{{cite web|url=http://www.psc.gov.uk/policy-and-consultations/consultations/postcode-address-file--management-of-information.html|title=Postcode Address File - review of the management of PAF|author=PostComm|access-date=5 October 2009|archive-url=https://web.archive.org/web/20081120062729/http://www.psc.gov.uk/policy-and-consultations/consultations/postcode-address-file--management-of-information.html|archive-date=20 November 2008|url-status=dead|df=dmy-all}}</ref>
 
The accounts for the PAF for 2005/6 disclosed an income of £18million, 8.6% of which was profit.<ref>{{cite web|url=http://www.psc.gov.uk/postcomm/live/policy-and-consultations/consultations/postcode-address-file--management-of-information/PAF_decision_doc.pdf|title=Royal Mail's Future management of PAF|date=April 2007|access-date=5 October 2009|archive-url=https://web.archive.org/web/20090324084021/http://www.psc.gov.uk/postcomm/live/policy-and-consultations/consultations/postcode-address-file--management-of-information/PAF_decision_doc.pdf|archive-date=24 March 2009|url-status=dead|df=dmy-all}}</ref>
