What & Why: Understanding London Postal Codes

What are London Postal Codes?

London postal codes, also known as zip codes in some countries, are alphanumeric codes used by Royal Mail to sort and deliver mail efficiently. They pinpoint specific geographic areas, ensuring mail reaches its intended destination quickly and accurately. A typical London postal code looks like this: 'SW1A 0AA'.

Why are Postal Codes Important?

• Efficient Mail Sorting: Postal codes allow Royal Mail to automate mail sorting, significantly speeding up the delivery process.

The Structure of a London Postal Code

A typical London postal code consists of two parts, separated by a space:

1. Outward Code: This part identifies the postal area and district. For example, in 'SW1A 0AA', 'SW1A' is the outward code. The first one or two letters indicate the postal area, such as 'SW' for South West, 'E' for East, 'N' for North, 'NW' for North West, 'W' for West, 'EC' for East Central and 'WC' for West Central.
2. Inward Code: This part identifies a group of addresses. In 'SW1A 0AA', '0AA' is the inward code. The last digit indicates the sector.
