In the Nomenclature of Territorial Units for Statistics (NUTS) codes of the United Kingdom (UK), the three levels are:
In the first version in 2003, North Eastern Scotland (which then included part of Moray) was coded UKM1, and Highlands and Islands was coded UKM4.
The current NUTS level 1 codes start with "C" (following "UK") rather than "1" because the new list reflected the revised regions of England and local government changes throughout the UK; "1" to "B" had been used for the 11 regions in the previous coding system.
NUTS 2006 came into force on 1 January 2008.
NUTS 2010 came into force on 1 January 2012.

The combined area of UKD2 (Cheshire pre-2010) and UKD5 (Merseyside pre-2010) were replaced by UKD6 (Cheshire post-2010) and UKD7 (Merseyside post-2010), due to the transfer of Halton to the Merseyside NUTS region from Cheshire. This resulted in the following changes to the underlying NUTS 3 areas: UKD22 (Cheshire CC) being split into UKD62 (Cheshire East) and UKD63 (Cheshire West and Chester); The areas of Liverpool, Sefton and Wirral were not changed as NUTS 3 areas however to reflect their transfer within NUTS 2 areas were respectively renumbered from (UKD52 to UKD72; UKD53 to UKD 73 and UKD54 to UKD 74). The two areas of UKD51 (East Merseyside pre 2010) and UKD21 (Halton and Warrington) were amended by the transfer of Halton from the latter to former to from the new areas of UKD71 (East Merseyside post-2010) and UKD61 (Warrington).
