The map shows our United Kingdom postal code coverage with major cities and postal code distribution.

United Kingdom's Postal Code Format

The United Kingdom uses a “Postcode” system, which is an alphanumeric format like AA9 9AA. This format typically consists of six to eight characters, with a space separating the outward code (area and district) from the inward code (sector and unit). The GeoPostcodes world postal code database indicates that the United Kingdom has 1,795,653 postcodes covering 402 regions and 32,082 towns. Unlike the purely numeric five-digit US ZIP codes, the UK Postcode system is alphanumeric and more granular, often identifying a handful of addresses.
  • Postcode Format: AA9 9AA

    • Alphanumeric format, 6–8 characters with a space before the last 3
    • Extremely granular, often down to a single building (~15 addresses per unit)
    • 1,795,653 postcodes covering 402 regions and 32,082 towns

    Examples:

    • SW1A 1AA - London (England)
    • EH1 1BB - Edinburgh (Scotland)
    • CF10 1AA - Cardiff (Wales)
    • BT1 5GS - Belfast (Northern Ireland)
  • Structure of Postal Codes

    • Format: AA9 9AA, alphanumeric
    • Hierarchical levels: Outward code (area + district) and inward code (sector + unit); often down to a single building.
    • Key challenges: Not geographically hierarchical: some codes span boundaries for routing efficiency. British Forces and island codes are handled separately. Administrative boundaries and postal boundaries do not align well, especially across country borders (e.g., Wales-England).
  • Management & Authority

    • Primary postal authority: Royal Mail.
    • Update frequency: The data is only available through resellers, and update frequency may vary.
    • Coverage: Applies to England, Scotland, Wales, Northern Ireland; British Forces postcodes are managed separately.
  • Addressing Standards

    • Common address format: [Double Dependent Locality] + [Dependent Locality] + [Post Town in capitals] + [Postcode].
    • Administrative divisions used: None encoded; postcode data is linked to admin divisions externally.
    • Notes: Dependent and double dependent localities are unique to Royal Mail routing and do not always match administrative geography.
  • Special Characteristics

    • Micro-postcodes usually cover around 15 addresses (range 1–100).
    • High change rate: 10,000+ postcode updates per quarter are common.
    • Postal and administrative boundaries do not align cleanly, especially in border areas.
    • Postcode data is licensed, not open; derivative datasets cannot be marketed as “official Royal Mail data.”
