How does Worthing postcode lookup work?
A Worthing 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.

AutoPostcode's Worthing data is drawn from the same national PAF file used by Royal Mail, so a lookup in Worthing 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.
