The geographic coordinates assigned to a large user postcode may not necessarily be the actual coordinates of the location to which mail is delivered. If the address is a PO Box, then the coordinates will usually be the Royal Mail sorting office which handles mail for that postcode. In other cases, the coordinates of the postcode may be the headquarters, or registered office, of an organisation rather than the building which receives mail.
