Legal Entity Identifier is a global identifier designed for unique, trustful, and unambiguous identification of legal entities participating across global markets. Simply, LEI is a 20-character code based on ISO 17442. LEI code provides two basic information about a legal entity: ‘Who is who’ and ‘who owns whom’

Structure of the LEI code for European Central Bank:  549300DTUYXMJXZNY75

The number allocation scheme was specified in Annex 2 of the Financial Stability Board’s third progress note on the Global LEI Initiative on 24 October 2012:

  • Characters 1-4 [ 5493]: The first four-character prefix allocation is unique to each Local Operating Unit (LOU) issuing LEIs. This prefix identifies (except for LEIs issued before 30 November 2012) the LOU that first issued the LEI and contributes to avoiding that different LOUs would assign the same LEI. However, the entity might have subsequently ported the maintenance of its LEI to a different LOU. Refer, GLEIF’s search feature to verify which LOU is maintaining an LEI (“Managing LOU” field) and go to this LOU’s website to update the reference data of the entity or certify that it is still up-to-date.
  • Characters 5-6 [00] : Two reserved characters set to zero.
  • Characters 7-18 [DTUYXMJXZNY ]: Entity-specific part of the code generated and assigned by LOUs according to transparent, sound and robust allocation policies.
  • Characters 19-20 [75]: Two check digits to avoid typing errors. The check digits are described in the ISO 17442 standards. The check digit scheme follows ISO/IEC 7064 (MOD 97-10) contributes to avoiding typing errors.

As specified in ISO 17442:2012, the reference data stored in the LEI data base for each entity includes:

  1. Official name
  2. Headquarters
  3. Address of legal formation
  4. First LEI assignment date
  5. Last updated date of LEI
  6. Expiration date of LEI, if applicable
  7. Reason for expiry. If applicable, display the acquired or merged entity’s LEI
  8. Official business registry where the foundation of the legal entity is mandated to be recorded on formation of the entity, where applicable
  9. The reference in the official business registry to the registered entity, where applicable.

For the stability of global financial systems, regulators and investors required transparent information about entities crossing the boundaries of markets, countries, states and region, especially after the 2008 meltdown. This realization led G20 forum commission the FSB (Financial Stability Board). FSB formed LEI ROC in 2012.  One year later LEI ROC, as part of FSB founded GLEIF, the organization dedicated to implement LEI system.
