GLEIF Entity Registry

Live

Resolve a company name to its LEI and an operator subsidiary to its ultimate parent company.

What is GLEIF Entity Registry?

GLEIF (Global Legal Entity Identifier Foundation) — the open global registry of legal entities. Resolve a company name to its 20-character LEI, fuzzy-match partial/variant names, and walk ownership: an LEI to its direct or ultimate parent entity. The headline use case: regulators (RRC, state agencies) list dozens of subsidiary names for one major operator — GLEIF maps those subsidiaries back to the ultimate parent. Global coverage including private subsidiaries that SEC EDGAR doesn't carry. Free, no auth. Toggle on and use.

Available Tools

searchEntities
Search legal entities by name; returns LEI, jurisdiction, status, address.
suggestEntities
Fuzzy autocomplete: resolve a partial/variant company name to candidate LEIs.
getEntity
Fetch one entity by its 20-character LEI.
getUltimateParent
Resolve an LEI to its ultimate parent entity (null if top-level).
getDirectParent
Resolve an LEI to its direct parent entity (null if none).
