UK postal codes are known as postcodes.
UK postcodes are alphanumeric. These codes were introduced by the Royal Mail over a 15-year period from 1959 to 1974 — the full list is now available electronically from the Royal Mail as the Postcode Address File. They have been widely adopted not just for their original purpose of automating the sorting of mail but for many other purposes such as insurance premium calculations and as a way to describe United Kingdom locations to route planning software, and as the lowest level of aggregation in census enumeration.
UK postcodes are copyrighted, but there is a project to help create a free postcode system - see http://www.freethepostcode.org/
However, as the format of the codes does not achieve its objective of primarily identifying the main sorting office and sub-office they have been supplemented by a newer system of five-digit codes called Mailsort — but only for mailings of 'a minimum of 4,000 letter-sized items'.[1] Mail users who can deliver mail to the post office sorted by Mailsort code receive discounts but [bulk] delivery by postcode provides no such incentive.
