What a Legal Entity Identifier (LEI) record shows

Confirm the legal entity behind a counterparty, whether its record is current and which parents it reports.

In short

A Legal Entity Identifier (LEI) is a 20-character code, defined by ISO 17442, that identifies one legal entity worldwide. LEIs are issued by organisations accredited by the Global Legal Entity Identifier Foundation (GLEIF), which publishes every record free of charge. A record gives the entity’s legal name, addresses and business-register number and, where reported, its parent entities. A BIC identifies an institution in payment messages; the LEI identifies the legal entity. Swift and GLEIF publish a file that maps one to the other.

An LEI has three parts

Elucidate GmbH’s LEI is 391200AZ2XGBV3BEY487. It breaks down as follows.

  1. 3912Issuer
    Characters 1–4
  2. 00AZ2XGBV3BEY4Entity
    Characters 5–18
  3. 87Check digits
    ISO 7064, MOD 97-10

The first four characters identify the organisation that issued the LEI. The fourteen that follow are assigned by that issuer. Unlike a BIC, they carry no meaning: an LEI does not encode the entity’s name, country or type.

The check digits let software reject most mistyped LEIs. A valid LEI may still belong to an entity other than the one in front of you, so compare the record.

The record shows who the entity is

GLEIF calls this the reference data, or level 1. The main fields are these.

FieldWhat it holds
Legal nameThe name in the entity’s business register, with any other names it uses.
AddressesThe legal (registered) address and the headquarters address.
Registration authorityThe business register and the entity’s number in it. For Elucidate GmbH: Amtsgericht Charlottenburg, HRB 196707 B.
Legal formThe form of the entity, as an ISO 20275 entity legal form (ELF) code.
Entity statusWhether the entity is active or inactive, as reported.
Registration statusWhether the LEI record is current (below), with the next renewal date.

Registration status shows whether the record is current

An LEI record must be renewed every year. The issuer then checks it again against the business register.

StatusMeaning
ISSUEDThe record was validated and is renewed on time.
LAPSEDThe record was not renewed by its renewal date. The LEI stays the entity’s identifier, but its data may be out of date.
MERGEDThe entity merged into another entity, which has its own LEI.
RETIREDThe record is no longer maintained, for example because the entity was dissolved.
ANNULLED, DUPLICATEThe LEI was issued in error, or duplicates another LEI of the same entity.

A lapsed record does not by itself mean that the entity has stopped trading.

Relationship records show reported parents

Since 2017, entities with an LEI report their direct and ultimate parents. GLEIF calls this level 2, or “who owns whom”. A parent here is the entity that consolidates the child in its accounts, under accounting standards such as IFRS. These records show accounting consolidation, not ownership. They do not name natural persons.

An entity that does not report a parent gives a reason instead, for example that it is owned by natural persons or that its parent does not consolidate it. International branches can hold their own LEI, linked to the LEI of their head office.

The directory groups institutions by these records: see the corporate groups.

Swift and GLEIF map BICs to LEIs

Swift and GLEIF publish a free file that maps BICs to the LEIs of the entities that hold them, the BIC-to-LEI relationship file. One LEI can be mapped to several BICs, such as a bank’s head-office BIC and the BICs of its foreign branches. A branch code can be mapped to an LEI other than its head office’s, for example that of an international branch.

Not every BIC is mapped. Write “no LEI mapped”, not “has no LEI”: the entity may hold an LEI that the file does not link to its BIC.

GLEIF publishes similar mapping files for other identifiers, including the Market Identifier Code (MIC, ISO 10383) of trading venues.

Where an LEI is required

Regulators require an LEI in many reports, for example derivatives reporting under EMIR and transaction reporting under MiFIR in the EU and swap reporting to the US Commodity Futures Trading Commission (CFTC).

In ISO 20022 payment messages, the LEI of a party or a financial institution goes in its <LEI> element.

What an LEI does not tell you

  • Who the beneficial owners are. Parent records name legal entities that consolidate the entity, not the people who own or control it.
  • Whether the entity is licensed. An LEI is not an authorisation. See how to check a payment firm’s licence.
  • Whether a counterparty is safe to deal with. An LEI identifies; it does not assess.

Look up an LEI. The directory shows the institutions mapped to an LEI, their BICs, their licences and their corporate group.

FinCrime Index

Assess the financial crime risk behind a counterparty

A BIC, an LEI or a licence identifies an institution. It does not assess it. The Elucidate FinCrime Index (EFI) is an independent score of the financial crime risk of banks and payment firms.
