What & Why

What are London Postcodes?

London postcodes are alphanumeric codes that Royal Mail uses to sort and deliver mail efficiently. They divide London into smaller geographic areas, enabling faster and more accurate delivery services. These postcodes are an integral part of the UK's address system, ensuring mail reaches the correct destination.

Why Use Postcodes?

The use of postcodes offers several benefits:

• Efficient Mail Delivery: Postcodes allow Royal Mail to sort mail quickly and accurately, reducing delays and misdeliveries.
• Location Identification: Postcodes help identify specific locations within London, aiding in navigation and emergency services.
• Data Analysis: Postcode data is valuable for businesses and organizations for market research, targeted advertising, and logistical planning.
• E-commerce: Online retailers rely on postcodes to calculate shipping costs and ensure accurate delivery addresses.

The Structure of a London Postcode

A typical London postcode consists of two parts: the outward code and the inward code.

• Outward Code: This part precedes the space in a postcode (e.g., NW1 in NW1 0AA). It indicates the postal area and postal district.
• The first one or two letters signify the postal area (e.g., NW for North West).
• The following number indicates the postal district within that area (e.g., 1 for the primary district).
• Inward Code: This part follows the space in a postcode (e.g., 0AA in NW1 0AA). It identifies a specific group of addresses.
• The first number indicates the sector.
• The last two letters designate the delivery point or a small group of addresses.
