Chapman code

Chapman codes are a set of 3-letter codes identifying the traditional administrative divisions in the United Kingdom, Ireland, the Isle of Man and the Channel Islands.

Use[edit]

They were created by the historian, Dr. Colin R Chapman, in the late 1970s, and as intended, provide a widely used shorthand in genealogy which follows the common practice of describing areas in terms of the counties existing from the 19th into the 20th century, avoiding the confusions such as caused by the periodic creation and renaming of unitary authorities in the United Kingdom by substituting the established names of the areas which they serve.

Other uses[edit]

Chapman codes have no mapping, postal or administrative use. They can however be useful for disambiguation by postal services where a full county name or traditional abbreviation is not supplied after a place name which has more than one occurrence, a particular problem where these are post towns such as Richmond.
