Royal Mail PAF daily data updates
Our Royal Mail address data is updated with daily PAF file updates from the Royal Mail, collects from feedback from 70,000+ postmen and women. See the status of the Royal Mail PAF file in this page
Unlike many of our competitors, who apply monthly updates, we update our data daily, directly from Royal Mail.
Royal Mail makes hundreds, sometimes thousands, of address changes daily to the 33,437,515 million addresses in the PAF (Postcode Address File) database. Every morning, the PAF file is updated with information from council property applications and 70 thousand postmen and women on their rounds.
Our servers automatically download the PAF file updates from Royal Mail every night. This means our Postcode Software customers have the latest PAF data available every day. The PAF file is the most complete and up-to-date address database in the UK. As one of the world`s largest address databases, it is recognised as a world-class address dataset.
The following diagram shows how updates are processed from feedback received from 70 thousand Royal Mail postmen and women on their rounds every morning.
This means that you do not have to apply periodic data updates or worry about managing Royal Mail updates, because we do that for you. Please read some of our customer comments.

Royal Mail Additional Data

Not Yet Built (NYB)
In addition to Postcode Address File data, we can provide Not Yet Built data. This currently contains 728,749 extra addresses for properties under construction or in the planning stage. This information can be particularly useful to the construction industry.
When these properties can receive mail, they are added to the PAF file by Royal Mail. Please contact us if you would like a quote.
Multiple Residencies (MR)
The PAF file lists every delivery point for mail, such as a letterbox or a group of letterboxes. It was designed to hold a maximum of 100 individual addresses within one postcode.
Where multiple mailboxes exist behind one delivery point, such as in a block of flats, additional detail may be required. The Multiple Residencies database lists the individual mailboxes at these addresses. It currently contains 947,057 additional addresses, extending the Royal Mail PAF file.
Taxi Locations
Our V3 Open API Json Web Service and our SimplyCompleteAI Address Finder, which return GeoLocation as part of the address, now has the option of Taxi Location data in addition to the Royal Mail PAF data.
It which contains:
Since these are not in the PAF database and receive no mail, they have no Postcode. They are purely for booking and quoting for Taxi, based on GeoLocation. The postcode will be returned as "UNKOWN".
