This field contains the Royal Mail Postcode Address File (PAF) postcode where the local authority address has been matched to PAF, that is, the POSTCODE field found within the Delivery Point Address table. Where a match has not been made, the postcode information is sourced from the local authority in collaboration with Royal Mail. Where the local authority does not hold a current valid postcode, a nearest neighbour function is used to spatially derive the postcode based on the position of the nearest UPRN which has a valid PAF match or valid local authority postcode assigned to it. The postcode value for Street Records (Classification "PS") will always be spatially assigned. This field must be used in conjunction with the RPC field to determine the accuracy of its position.
