Legal Entity Identifier (LEI) vs Unique Taxpayer Reference (UTR) in the UK

The Legal Entity Identifier (LEI) is a standard identifier that provides verified data on legal entities and is registered on a centralised system, the Global LEI System. The Tax Identification Number (TIN) in the United Kingdom for entities is the Unique Taxpayer Reference (UTR). In the UK, UTR-s are used to identify companies for all tax-related purposes.

The LEI is a 20-character alphanumeric code based on the ISO 17442 standard developed by the International Organization for Standardization (ISO). LEI number references important information that offers transparency when participating in financial transactions such as trading with stocks, bonds, or forex.

LEI connects to key reference information that enables a clear and unique identification of legal entities participating in financial transactions on a global scale. Each LEI contains well-structured reference data categorised into two sections: Level 1 – who is who and Level 2 – ‘who owns whom’.

‘Level 1’ data includes entity registration details, such as legal name, number of registration, legal and HQ address, etc. Level 2 contains information about an entity’s ownership structure and thus answers the question of ‘who owns whom.’

Simply put, the publicly available LEI data pool transfers unstructured entity registration data into a standardised global directory, which helps to enhance transparency in the global marketplace.

How to get an LEI in the UK?

An LEI number must be obtained through an LEI service provider, a Local Service Provider (LOU), or a Registration Agent. The Global LEI System (GLEIS) encourages competition between LEI issuers and registrators to benefit legal entities seeking an LEI. Generating a price for issuing and maintaining an LEI has therefore been left to the organisations themselves. This explains why some companies charge double the price of their competitors.
