Welcome to a financial world, full of mysterious acronyms. LEI, CASS, ECP, EMIR, MiFIR, MTF, OTF…

This industry just loves acronyms and MiFID II just gave us a whole lot of new ones to work with.

One that I have started hearing more often is the LEI number and it relates directly to the requirements embedded in the upcoming MiFID II directive. The following article will hopefully give answers to these much-asked questions, what is an LEI? Who needs one? Why it is required? How do I get one?

What is an LEI number?

LEI, or Legal Entity Identifier, is a unique identifier for persons that are legal entities or structures including companies, charities and trusts.
The Legal Entity Identifier (LEI) is a 20-character, alpha-numeric code, to uniquely identify legally distinct entities that engage in financial transactions.

How does the LEI relate to MiFID II?

As a part of MiFID II, all legal entities that trade with an EU-licensed broker need to be identified by their LEI. Here is an excerpt from the directive:

“In order to facilitate market surveillance, client identification should be consistent, unique and robust. Transaction reports should therefore include the full name and date of birth of clients that are natural persons and should identify clients that are legal entities by their LEIs.“

Who needs an LEI number?

If you are a corporate trader and your company is trading, let’s say, with a FCA or CySEC licensed broker and, you have to submit your LEI number in order to be properly identified in transactions reports submitted by the broker to their regulator.

Where can you get an LEI number?

Established in June 2014, the Global Legal Entity Identifier Foundation (GLEIF) is a not-for-profit organization created to support the implementation and use of the LEI. The Global Legal Entity Identifier Foundation (GLEIF) is responsible for monitoring and ensuring high quality Legal Entity Identifier (LEI) data.

Global LEI number System

LEIs are issued by “Local Operating Units” (LOUs) of the Global LEI System. LOUs make the LEIs and associated reference data available to the public and regulators free of charge and on a continuous basis. EU regulated firms need to make sure that LEIs are issued and maintained using global standards.

Registered LEI number carries the following information is stored about your entity:

The official name of the legal entity as recorded in the official registers.

  • The registered address of that legal entity.
  • The country of formation.
  • The codes for the representation of names of countries and their subdivisions.
  • The date of the first LEI assignment; the date of last update of the LEI information; and the date of expiry, if applicable.

There are 530,940 LEI numbers issued in the world, of which 132,272, or 24.9% are in the Unites States.
