How does FY postcode work?
A FY postcode matches a full or partial postcode against Royal Mail's Postcode Address File (PAF), the UK's official address database of around 31 million addresses across roughly 1.8 million postcodes. You type a FY postcode, AutoPostcode returns every deliverable address at that location in milliseconds, and the user selects the correct one — no manual typing, no typos.
AutoPostcode's FY data is drawn from the same national PAF file used by Royal Mail, so a lookup in FY is as accurate as anywhere else in the UK. Integrate it through our postcode lookup API or drop the widget into any checkout with a few lines of code.
Which postcodes does FY use?
The FY postcode area is anchored on Blackpool, running from FY1 in the town centre out to Lytham St Annes (FY8), Fleetwood (FY7), Thornton-Cleveleys (FY5) and Poulton-le-Fylde (FY6). All FY districts resolve against Royal Mail PAF.
