What & Why of London Postal Codes

What are London Postal Codes?

London postal codes are alphanumeric codes used by the Royal Mail, the UK's postal service, to sort and deliver mail. Each postal code typically covers a small group of addresses, such as a street, a part of a street, or an individual building. They are an essential part of the UK's postal address system, which helps to ensure mail is delivered efficiently and accurately.

Why Use Postal Codes?

Postal codes serve several critical purposes:

• Efficient Mail Sorting and Delivery: Postal codes enable the Royal Mail to sort mail quickly and accurately, ensuring it reaches the correct destination.
• Location Identification: Postal codes provide a valuable way to identify the location of a property or business within London.
• Navigation and Mapping: Postal codes are used in GPS systems and online maps to pinpoint addresses and calculate routes.
• Data Analysis and Demographics: Postal codes are used for demographic analysis, market research, and urban planning.
• Property Valuation: Postal codes are also considered in property valuation, as some areas within London are more desirable and expensive than others.

Structure of London Postal Codes

London postal codes are structured in a specific format that provides information about the location. A typical London postal code consists of two parts, separated by a space:

1. Outward Code: The first part is the outward code, which identifies the postal area and postal district. It consists of one or two letters followed by one or two numbers. For example, in the postcode "SW1A 0AA", "SW1A" is the outward code.
2. Inward Code: The second part is the inward code, which identifies the postal sector and delivery point. It consists of a number followed by two letters. For example, in the postcode "SW1A 0AA", "0AA" is the inward code.

Let's break down each component:

• Postal Area: The first one or two letters of the outward code indicate the postal area. London is divided into several postal areas, such as "N" for North London, "SW" for Southwest London, and "E" for East London.
• Postal District: The numbers in the outward code specify the postal district within the postal area. For example, "SW1" is the postal district for part of Southwest London.
• Postal Sector: The number in the inward code represents the postal sector within the postal district. For example, in "SW1A 0AA", "0" indicates a specific sector within the "SW1A" district.
• Delivery Point: The two letters in the inward code identify the specific delivery point, which could be a street, a group of addresses, or an individual building.
