The UK's address landscape never stands still. Royal Mail records changes to the Postcode Address File on an ongoing basis and releases refreshed data frequently, so the dataset stays an accurate mirror of reality.
What drives the constant change
Staying current automatically
With AutoPostcode you don't manage PAF refreshes — we keep the underlying data synced so every lookup uses up-to-date records. See PAF data access or the PAF guide hub.
Frequently asked questions
How often is PAF updated?
Royal Mail updates the Postcode Address File continuously as addresses change, and publishes refreshed datasets very regularly — providers like AutoPostcode keep their data in sync so lookups stay current.
Why does PAF change?
New homes are built, properties are converted or demolished, streets are renamed and businesses move — Royal Mail reflects all of this in PAF.
How many addresses change each year?
Hundreds of thousands of UK address changes occur annually, which is why static or scraped address lists quickly become inaccurate.
