LEI codes

An LEI (Legal Entity Identifier) is a global organisational code which identifies companies and legal entities on the financial market. The requirement to use LEI codes is based on EU legislation about securities.

Companies and entities, for example registered associations and foundations, need an LEI code when trading in listed shares, exchange-traded fund (ETF) units and other securities or derivatives listed on the stock exchange.

You do not need to have an LEI code if you just own financial instruments.

Companies and entities with Finnish Business IDs, excluding branches, can apply for an LEI code at the Finnish Patent and Registration Office (PRH).

The PRH will not send a decision on the issuance of the LEI code. You can see the LEI code issued to a company or an entity in its details in the company search at, which is jointly provided by the PRH and the Finnish Tax Administration. The LEI code is shown in the search result under “LEI details" after “Business ID history". Go to the company search.Open link in a new tab
