LEI code

The LEI code is a 20-character international identifier for the clear identification all over the world of legal entities (banks, issuers, listed companies, stock exchange traders, investment funds, etc.) participating in financial transactions.

Issuers approved (Local Operating Unit - LOU) by the Global Legal Entity Identifier Foundation (GLEIF) are entitled to issue LEI codes. Until receiving GLEIF approval to issue LEI codes, KELER continuously assists market participants in accessing the LEI code without delay. To this end, KELER contracted WM Datenservice in Germany.

In order to remain valid, the LEI codes requested must be renewed annually. We inform Clients before the expiry of the LEI codes already managed by KELER to ensure the codes are renewed in time. It is possible to renew through KELER the LEI codes issued by other LOUs; in line with the mandate of the Client, KELER takes the necessary steps to renew the code.

Details of LEI code administration can be found below, in our Client Information under the Documents section.

Our colleagues are ready to help Clients with any questions that may arise.

Regulations of particular importance for KELER Clients requiring the existence and use of the LEI code:

  • Regulation (EU) No 648/2012 of the European Parliament and of the Council on OTC derivatives, central counterparties and trade repositories (EMIR) entered into force on 16 August 2012 and requires financial service providers to identify clearly with unique identifiers the transacting counterparties in the reports to be submitted on derivative transactions. EMIR requires primarily the use of the so-called Legal Entity Identifier (LEI) code for identification purposes. In addition to LEI codes, the Regulation expects the codes to be valid at the time the trade is made.
  • Based on Directive 2014/65/EU of the European Parliament and of the Council on markets in financial instruments and amending Directives 2002/962/EC and 2011/61/EU (MiFID II) all investment firms, legal entities and issuers of securities listed on regulated markets are required to have LEI codes as of 3 January 2018.
  • Regulation (EU) No 909/2014 of the European Parliament and of the Council on improving securities settlement in the European Union and on central securities depositories (CSDR) and the related regulations require issuers to have LEI codes and such LEI codes to be valid in the case of certain events (creation, over-issuance, conversion and (daily) over-issuance of open-ended investment units) related to dematerialized securities. In line with the provisions of the CSDR, KELER is required to check that the issuer LEI code is valid.
