The postcode unit that the Address is situated within. A postcode is an abbreviated form of address, made up of combinations of between five and seven alphanumeric characters. These alphanumeric characters are used by Royal Mail to help with the automated sorting of mail. A postcode may cover between 1 and 100 addresses. Postcodes (for example, NW6 4DP) are comprised of two components. The first component is the outward code (or ‘outcode’), which is the first two to four characters of a postcode, constituting the postcode area and the postcode district, for example, NW6. The outward code is the part of the postcode that enables mail to be sent from the accepting office to the correct area for delivery. The second component of a postcode is the inward code (or ‘incode’), which is the last three characters of the postcode, constituting the postcode sector and the postcode unit, for example, 4DP. The inward code is used to sort mail at the local delivery office. This field will contain the Royal Mail Postcode Address File (PAF) postcode where the Local Authority address has been matched to PAF. Where a match has not been made, the postcode information is sourced from Local Authority assigned data. In cases where the Local Authority do not hold a valid postcode, a spatial nearest neighbour function is used to spatially derive the postcode from the closest Address with a valid postcode.
