How does Reading postcode lookup work?
A Reading 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 Reading 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 Reading data is drawn from the same national PAF file used by Royal Mail, so a lookup in Reading 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 Reading use?
Reading sits within the RG postcode area, from central RG1 out to suburbs such as Whitley (RG2), Caversham (RG4) and Earley (RG6). The wider RG area also covers Wokingham, Bracknell and Basingstoke, all resolvable against Royal Mail PAF.
