GLEIF LEI Lookup & Entity Resolver

The GLEIF LEI Lookup & Entity Resolver searches the Global Legal Entity Identifier Foundation's public LEI data.

It supports two useful research modes:

• Exact LEI lookup when you already know a 20-character Legal Entity Identifier.
• Legal-name search when you need candidate entities that can be resolved using jurisdiction, address, status and registration information.

What an LEI is

A Legal Entity Identifier is a globally unique identifier assigned to legal entities participating in financial and other official transactions.

An LEI record can provide structured fields such as:

• legal name;
• LEI;
• entity status;
• legal jurisdiction;
• legal address;
• registration status;
• registration/update dates.

Not every company has an LEI.

No result therefore does not prove that a company does not exist.

Strong workflow

Use the tool in this order:

1. search the legal name or exact LEI;
2. treat name results as candidates;
3. compare jurisdiction and address;
4. preserve the LEI when a candidate is resolved;
5. corroborate material corporate facts against the relevant official registry.

The LEI is especially useful as a stable identifier when moving between datasets.

What it does not prove

An LEI record does not automatically establish:

• beneficial ownership;
• current operational control;
• sanctions status;
• commercial activity;
• every corporate relationship.

It is a strong legal-entity identifier and reference-data layer.
