How UK postcodes work
A UK postcode such as SW1A 1AA has two parts separated by a space. The outward code (SW1A) is the postcode district: its letters (SW) are the area, usually named after the main post town. The inward code (1AA) narrows it down: its first digit gives the sector (SW1A 1) and the last two letters the exact unit, typically one street or part of a street with around 15 addresses.

The post town is written in capitals and the postcode is the last line, also in capitals, with one space.
