Global LEI System

The ROC oversees the Global LEI System (GLEIS), which is composed of the ROC itself, the Global LEI Foundation (GLEIF), and LEI issuers known as Local Operating Units (LOUs).


The LEI is a 20-character reference code to uniquely identify legally distinct entities that engage in financial transactions and associated reference data. Two fundamental principles of the LEI code are:

The LEI definition currently relies on a standard published by the International Organisation for Standardisation (ISO) on 30 May 2012 (ISO 17442:2012, Financial Services - Legal Entity Identifier (LEI)).

The LEI Code is structured as follows:

Reference data and relationship data

The reference data stored in the LEI data base for each entity includes:

The Global LEI Foundation

The Global LEI Foundation (GLEIF) was established in June 2014 as a not-for-profit organization overseen by the ROC to act as the operational arm of the GLEIS. The foundation provides on their website a centralized database of LEIs and corresponding reference data.  A search function was added in October 2015, where one can check if an entity has an LEI, or access the reference data associated with an LEI, including verifying whether the LEI is current and can be used in regulatory reporting (registration status: "issued" or "pending transfer"). From 7 October 2015, new institutions that wish to become LEI issuers need to be accredited by the GLEIF, which monitors their compliance with the standards of the GLEIS. As of this date, the GLEIF also assumed the tasks of defining and maintaining the operational and technical standards of the system. The GLEIF also publishes the list of authorised LEI issuers.

Local Operating Units

LEIs are issued by "Local Operating Units" (LOUs) of the Global LEI System.

LOUs are the utilities accredited by the GLEIF under ROC oversight, to provide LEIs and other services to registrants.

LOUs make the LEIs and associated reference data available to the public and regulators free of charge and on a continuous basis.

The list of LOUs accredited by the GLEIF can be found on the GLEIF website.  

Some of these registries serve a given country while others offer services to entities worldwide. They may be differences as well in the languages available, facilities to register many entities in bulk, and price, among others. We invite you to check the websites of these registries to find the one that best suits your needs.

These websites also provide information on the process for obtaining an LEI, which complies with general principles set by the ROC, in particular:
