LEI Entity Resolver

Match a company across identifier systems — LEI, national company number, BIC, MIC, OpenCorporates, S&P Global — with legal address, registration status and corporate ownership.

No login. No API key. No proxies.

The problem this actually solves

Finding a company is easy. Matching the same company between two systems is not — your CRM has a name, your bank file has a BIC, your finance system has an S&P id, and the French registry has a SIREN.

GLEIF carries all of them on one record. This Actor exports them as plain columns:

Field	Example (Airbus)
lei	529900FCMZ4LKXFD0R69
registeredAs	383 474 814 (the French SIREN)
registeredAt	the national registry that issued it
bic	AIRBFR22XXX
mic, ocid, spglobal, qcc, gem	other identifier systems

In testing, 98 % of French entities carried a national registration number — so a country-wide export is effectively a LEI↔national-ID mapping table.

Whole corporate groups in one run

Give a parent's LEI in Subsidiaries of this LEI and you get its entire ownership tree. Measured on NEOEN FRANCE: 116 owned entities, against 68 direct subsidiaries — the filter reaches indirect holdings the direct-children view misses, and it costs no extra lookups.

Add parent company and subsidiary count instead when you are going the other way: for each entity, its direct parent, ultimate parent and how many subsidiaries it has. That costs three API calls per row, so use it on a narrow selection.

Lapsed LEIs are a compliance signal

Set LEI registration status to LAPSED to list entities that failed to renew. There are over 73,000 in France alone. A counterparty whose LEI has lapsed is a flag worth raising before a transaction, and nobody surfaces it as a list.

Output

lei, legalName, otherNames, entityStatus, jurisdiction, legalForm, category, subCategory, creationDate, registeredAs, registeredAt, registrationStatus, initialRegistrationDate, lastUpdateDate, nextRenewalDate, managingLou, corroborationLevel, bic, mic, ocid, spglobal, qcc, gem, full legal and headquarters addresses, gleifUrl, plus directParentLei, directParentName, ultimateParentLei, ultimateParentName and directChildrenCount when hierarchy is requested.

Use cases

• Entity resolution — build a LEI↔SIREN↔BIC mapping table for a country.
• KYC and onboarding — ownership tree, registration status, renewal date.
• Counterparty screening — find lapsed or retired LEIs in a portfolio.
• Fund administration — every fund registered in a jurisdiction.
• Data enrichment — attach a stable global identifier to records that only carry a national one.

Limits, honestly

• GLEIF only accepts a fixed list of filters. City, postcode, region and headquarters country are refused by the API. Country of legal address, jurisdiction, name, full text, category, status, BIC, LEI and ownedBy all work. This Actor exposes only the ones that do.
• BIC is rare. Only financial institutions carry one, so a BIC column is mostly empty on a general export — that is the source, not the export.
• A lapsed LEI means the registration was not renewed. It does not by itself mean the company is gone.
• Hierarchy is self-declared under GLEIF's reporting rules, and not every group reports completely.
• Requests are paced out of courtesy to a free public service.
• Not affiliated with GLEIF.
