The Appropriate Entity Identifier (LEI) is a distinctive international identifier for legal entities participating in financial transactions. Also known as an LEI code or LEI number, their purpose is to simply help recognize appropriate entities on a internationally available database. Legitimate entities are organisations such as companies or government entities that take part in economic transactions. An individual individual may not obtain an LEI. The identifier is found in regulatory revealing to economic regulators and all economic businesses and resources are expected with an LEI.
