The Postcode is part of a coding system created and used by the Royal Mail across the United Kingdom for sorting mail. In other words, Postcodes are an abbreviated form of address, and enable a group of Delivery Points to be specifically identified. When originally created, the Postcode was ‘designed’ around the capability of Royal Mail sorting equipment to read and interpret typed or handwritten text on mail. This is why Royal Mail prefers the Postcode to be separate and on the last line of an address. The format and rules concerning Postcode layout, in particular which letters can or cannot be used, stem from the fact that certain letters or combinations of letters could be confused (e.g. ‘O’ and ‘Q’, or ‘V’ next to ‘V’ being misread as ‘W’).
