What is an LEI number?

An LEI number, or LEI code, is a 20-character code which functions as an international company or entity registration number. It references important information which offers transparency when partaking in financial transactions such as trading stocks, bonds, or forex. All legal entities – companies, charities, trusts, organisations, banks, and more – participating and dealing in financial transactions, stocks, bonds, and other securities in the UK require an LEI code.
