UK Postcode Postal codes used in the United Kingdom are known as postcodes (originally postal codes). They are alphanumeric and were adopted nationally between 11 October 1959 and 1974, having been devised by the GPO (Royal Mail). A full postcode is known as a "postcode unit" and designates an area with a number of addresses or a single major delivery point. "([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z]))))\\s?[0-9][A-Za-z]{2})"
