How does Preston postcode lookup work?
A Preston postcode lookup 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 Preston 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 Preston data is drawn from the same national PAF file used by Royal Mail, so a lookup in Preston 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.

Preston sits within the PR postcode area, from the city centre (PR1) to Fulwood and Ashton (PR2) and Bamber Bridge and Leyland (PR5). The wider PR area also spans Chorley, Leyland and much of central Lancashire, all resolvable against Royal Mail PAF.
