# Chapman code

Chapman codes are a set of 3-letter codes used in genealogy to identify the administrative divisions in the United Kingdom, Ireland, the Isle of Man and the Channel Islands.

## Use

They were created by the historian Colin R Chapman in the late 1970s, intended to provide a widely used shorthand in genealogy which follows the common practice of describing areas in terms of the counties existing in the 19th and 20th centuries.

## Other uses

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.
