Legal Entity Identifiers

What is an LEI Number?

What Is A Legal Entity Identifier (LEI)?

What is an LEI – a Legal Entity Identity (LEI) number is a unique 20-character alphanumeric string (i.e. 529900T8BM49AURSDO55) used to distinctly represent a Legal Entity (company, organization, firm, government body, trust, fund, etc) on a worldwide basis. Once issued the LEI number can be used to represent the entity in financial transactions or organization identity assurance use cases. LEIs are required by all parties participating in regulated transactions and provide a publicly available verifiable source of ‘who is who’ (organization identity) and ‘who owns whom’ (organization group structures).

The LEI is based on the ISO 17442 standard and assigned only to a single Legal Entity on a global basis. The system is maintained and operated by the Global LEI Foundation (GLEIF) and the ability to issue LEIs is only awarded to a limited number of organizations (like RapidLEI) passing a stringent accreditation process who then become LEI Issuers (formally known as LOUs – Legal Operating Units).

What type of Legal Entity may register an LEI number?

An LEI number may be requested by any of the following:-

  • Registered Companies* and Registered Subsidiaries*
  • Non Profits
  • Sole Proprietors (Having a distinct identity within a business register)
  • International Branch offices (The Head Office must already have an LEI)**
  • Funds and Trusts

*As a general rule, a Business Registry will usually bestow a status of “Good Standing” to a business which maintains accurate information within the registry and completes any annual filing requirements. A Legal Entity does NOT have to be in Good Standing to be issued with an LEI, but MUST be ACTIVE. i.e. Legal Entities which have been struck off, merged, withdrawn or de-registered will be unable to receive or renew their LEI number.

** A branch office within an alternative jurisdiction/state, but still within the same country as the head office is not eligible as only one LEI per country can currently be issued.
