How does BS postcode work?
A BS 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 BS 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 BS data is drawn from the same national PAF file used by Royal Mail, so a lookup in BS 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 BS use?
The BS postcode area is anchored on Bristol, running from BS1 in the city centre out to Weston-super-Mare (BS22–BS24), Portishead (BS20) and Thornbury (BS35). All BS districts resolve against Royal Mail PAF.
