How does Birmingham postcode lookup work?
A Birmingham 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 Birmingham 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 Birmingham data is drawn from the same national PAF file used by Royal Mail, so a lookup in Birmingham 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 Birmingham use?
Birmingham sits within the B postcode area, running from central districts B1 to B5 out to suburban districts such as B29 (Selly Oak) and B44 (Kingstanding). The wider West Midlands adds WV, DY and WS areas, all resolvable against Royal Mail PAF.
