How London Postcodes Work: A Breakdown

London postcodes are structured in two parts: the outward code and the inward code. Understanding these components helps you decipher the postcode and its geographic significance.

1. Outward Code

The outward code is the first part of the postcode and contains the postcode area and the postcode district.

• Postcode Area: This is a one- or two-letter abbreviation that indicates a general area of London (e.g., "SW" for Southwest London, "NW" for Northwest London).
• Postcode District: This is a one- or two-digit number (and sometimes a letter) that further divides the area into smaller districts (e.g., "SW1", "NW3").

Example: In the postcode "SW1A 0AA", "SW1A" is the outward code, with "SW" being the postcode area and "1A" the postcode district.

2. Inward Code

The inward code is the second part of the postcode and consists of a digit followed by two letters.

• Sector: The digit indicates a sector within the postcode district (e.g., "0" in "SW1A 0AA").
• Unit: The two letters identify a specific group of addresses, often a street or part of a street (e.g., "AA" in "SW1A 0AA").

Example: In the postcode "SW1A 0AA", "0AA" is the inward code. — El Tiempo En Round Lake: Pronóstico Actualizado
