ISIN → LEI

Find the issuer of a security

Enter a 12-character ISIN, such as US0378331005. It resolves to the LEI record of the entity that issued the security, using GLEIF’s ISIN-to-LEI relationship file.

Anatomy of an LEI

The code is opaque, but structured: the first four characters name the issuing organisation, the middle identifies the entity, the last two verify the whole thing.

Reference data

Legal name, form, registered address, registration authority and status — for every entity, or “Not reported” when GLEIF has no value.

Who owns whom

Direct and ultimate parents, subsidiaries and reporting exceptions, linked into a navigable ownership graph.

A change history

GLEIF discards prior values when they change. LEIatlas keeps every version, so you can see how an entity evolved.
