Legal Entity Identifier (LEI) Code

A Legal Entity Identifier (LEI) is a code that identifies distinct entities that engage in financial transactions.

The Central Securities Depository Regulation (CSDR) states that both counterparties must have a Legal Entity Identifier (LEI) code.

A legal entity can only have one LEI code, which is valid globally.

Use of LEI codes at Euronext Securities

The CSDR requires issuers and intermediaries to submit their LEI code to their Euronext Securities Central Securities Depository (CSD). This is part of the admission request process.

We record your LEI code and use it in our reporting to supervisory authorities.

Why are LEI codes required?

A LEI code carries information about its entity. It enables the exchange of information and ensures high quality, reliable data.

This supports supervision practises and increases the transparency of financial markets.

LEI code structure

The Global LEI System was started by the G20 forum and Financial Stability Board.

The structure of LEI codes and the minimum data associated with each code is outlined in: 

ISO standard ISO 17442 Financial services – Legal Entity Identifier (LEI).
