Navigating the UK's postal system can be a bit confusing, especially for those new to the country. There are over 1,800 postcodes in the UK, each serving a specific geographic area.
A post town is a key component of a postcode, and it's the name of the town or city where the postcode is located. For example, the postcode SW1A 0AA is located in the post town of Westminster.
In the UK, post towns are often the same as the name of the town or city, but not always. Some post towns are made up of multiple towns or cities, while others are a single town or city with multiple postcodes.
Understanding post towns is essential for sending mail and packages within the UK, so it's worth taking the time to learn about them.

UK Postcode System
The UK Postcode System is a complex but fascinating topic. The system is sorted by postcode area, which is the first part of the outward code of a postcode. This means that all postcodes in the UK start with a specific letter or combination of letters that represent a particular area.

Postcode areas are usually named after a major town or city, such as Birmingham (B), but not always. Some postcode areas are named after smaller towns or a combination of towns, like UB for Uxbridge or SM for Sutton and Morden.
The postcode area for London is a bit different, with eight distinct areas (N, E, EC, SE, SW, W, WC, and NW) that reflect the city's compass points.
