What is an LEI?

An LEI is a global organisational code which identifies companies and other legal entities on the financial market. LEI codes are used to improve the transparency of the financial market.

LEI is an abbreviation of Legal Entity Identifier. The code comprises 20 digits and is based on the ISO 17442 standard. Read more about LEI codes on the website of the Global Legal Entity Identifier Foundation (GLEIF).

See our LEI glossary.

The requirement to use LEI codes is based on EU legislation (MiFID II, MiFIR and EMIR). Under the EU securities regulation, entity clients must be identified using LEI codes in transaction reporting related to financial instruments and their derivatives. In Finland, LEI codes are used under the supervision of the Finnish Financial Supervisory Authority.
