International Territorial Level (ITL) is a geocode standard for referencing the subdivisions of the United Kingdom for statistical purposes, used by the Office for National Statistics (ONS). From 2003 and until 2020 it functioned as part of the European Union and European Statistical System's geocode standard Nomenclature of Territorial Units for Statistics or NUTS.
Following Brexit, the ONS set to develop a domestic statistical classification framework separate from NUTS. Currently, the ITLs are a mirror to the pre-existing NUTS system, they retain the same three level hierarchy and boundaries used for NUTS in the United Kingdom since 2018, with the next review scheduled for 2024. ITLs are set to follow a similar review timetable to NUTS, being reviewed every three years. The ONS will develop new official GSS codes of ITL geography aligned with the existing NUTS codes. From 1 January 2021, the ONS encourages "ITL" be used as a replacement to the "NUTS" designation, with lookups between NUTS and ITL maintained and published until 2023.[1][2]
The current ITL classification is a mirror of the previous NUTS classification with slight modification, the ONS lists 12 regions at ITL 1, 41 regions at ITL 2, and 179 regions at ITL 3.[1] "UK" in the NUTS codes were replaced with "TL".
The last NUTS classification is dated 21 November 2016 and was effective from 1 January 2018, listed 12 regions at NUTS 1, 40 regions at NUTS 2, and 174 regions at NUTS 3 level.

History
NUTS 2003
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
NUTS 2006 came into force on 1 January 2008.[4]
NUTS 2010
NUTS 2010 came into force on 1 January 2012.[4]
2010 changes to NUTS 2 also resulting in changes with NUTS 3 regions
- 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 form the new areas of UKD71 (East Merseyside post-2010) and UKD61 (Warrington).

- UKE43 (Calderdale, Kirklees and Wakefield) was replaced by UKE44 (Calderdale and Kirklees) and UKE45 (Wakefield)

In 2015 the Greater London NUTS 1 area was left unchanged however the previous NUTS 2 area of inner and outer London were abolished and with the previous NUTS 3 areas becoming NUTS 2 areas. Thus NUTS 2 of Inner London West UKI11 becoming the NUTS 3 area of UKI3 and likewise: Inner London East (from UKI12 to UKI4), Outer London East and North East (from UKI21 to UKI5), Outer London South (from UKI22 to UKI6) and Outer London West and North West (from UKI23 to UKI7). The NUTS 3 areas are now a single or a group of two or three boroughs.

ITL 2021
Following Brexit, the classification used by the ONS was replaced with ITLs. Between 2021 and the next review scheduled for 2024, the ITLs are a mirror of the NUTS classification adopted in 2018. All NUTS codes containing "UK" were changed to use "TL" for Territorial Level.
Local administrative units
 | Parts of this article (those related to since 2017 only one LAU-level with 383 units) need to be updated. (December 2023) |
Below the ITL levels, the two LAU (Local Administrative Units) levels are:
| Level | Subdivisions | # |
|---|---|---|
| LAU 1 | Lower tier authorities (districts) or individual unitary authorities (England and Wales); Individual unitary authorities or LECs (or parts thereof) (Scotland); Districts (Northern Ireland) |
415 |
| LAU 2 | Wards (or parts thereof) | 10400 |
The two LAU levels are maintained by the UK Office for National Statistics within the ONS coding system.
