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