Legal Entity Identifier (LEI)

Secure the identification of your legal entity

In order to become an issuer on one of the Luxembourg Stock Exchange (LuxSE)'s two internationally recognised markets, a Legal Entity Identifier (LEI) is required.
What is an LEI?
An LEI code is a 20-digit completely unique and universal identifier that helps create greater certainty when identifying a legal entity involved in financial transactions and facilitate counterparty risk monitoring and systematic risk management.

Why do I need an LEI?
Due to the framework set out by the Financial Stability Board (FSB) and echoed in MiFID II [1] / MiFIR [2] and MAR [3], LuxSE is obliged to collect an LEI code from any issuer operating on our regulated market and/or on our Multilateral Trading Facility (Euro MTF) and communicate the code to the relevant supervisory authorities.

How do I apply for an LEI?
If you are a legal entity involved in financial transactions, you can apply for an LEI through one of the Global Legal Entity Identifier Foundation (GLEIF)'s recognised local operating units (LOUS).
