How does DD postcode work?
A DD 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 DD 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 DD data is drawn from the same national PAF file used by Royal Mail, so a lookup in DD 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 DD use?
The DD postcode area is anchored on Dundee, running from DD1 in the city centre out to Arbroath (DD11), Forfar (DD8), Montrose (DD10) and Carnoustie (DD7). All DD districts resolve against Royal Mail PAF.
