There are two main components of a postcode, for example, NW6 4DP:

  • The outward code (or ‘outcode’). The first two–four characters of the postcode constituting the postcode area and the postcode district, for example, NW6. It is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery.
