There are many reasons a person might need to find a company’s LEI number, from completing a trade report to onboarding a new client or running a due diligence check. Because the Legal Entity Identifier system is built on open, public data, looking up any registered entity is quick and free once the right approach is known. This guide explains how to search for a company’s LEI number step by step, how to choose between searching by name or by code, and how to make sense of the results.
What Is an LEI Number?
An LEI number is a 20-character alphanumeric code based on the ISO 17442 international standard. It uniquely identifies a legal entity that participates in financial transactions anywhere in the world. Each LEI record holds publicly available reference data, including the entity’s legal name, registered address, country of formation, and registration status. Because that information is open by design, anyone can search for a company’s LEI number and verify the organisation behind it in a matter of seconds.
Why Search for a Company’s LEI Number?
Searching for an LEI serves several practical purposes. It allows a business to verify a counterparty before entering a transaction, which reduces the risk of dealing with the wrong entity. It supports know-your customer and due diligence checks during client onboarding. It confirms an organisation’s official legal name, address, and current status. It can also reveal parent and ownership relationships, helping users understand the wider corporate structure behind a single name.
How to Search for a Company’s LEI Number Step by Step Finding an LEI follows the same simple process regardless of the entity:
- Choose a search tool. Use a reliable LEI lookup service such as LEI Search, which lets users search by company name or by an existing LEI code.
- Enter the search term. Type the company’s full legal name or, if it is known, the 20-character LEI code directly into the search field.
- Review the matching results. Scan the list of entities returned and select the record that matches the correct legal name and jurisdiction.
- Open and read the record. Check the full details, including the LEI itself, the registration status, the registered address, the next renewal date, and any reported parent relationships.
The whole process usually takes less than a minute, and there is no cost to look up an existing record.
Searching by Company Name vs. LEI Code
Both search methods are useful, but they suit different situations. Searching by LEI code is the most precise option because the code is unique, so it returns a single, exact record. Searching by company name is helpful when the code is not known, although it can return several similar results, especially for large groups with many subsidiaries or for common business names. To narrow a name search, users should enter the exact registered legal name and, where possible, filter by the entity’s jurisdiction or country to avoid selecting the wrong organisation.
How to Read the Search Results
Once the correct record is open, the registration status is the first detail to check. An active status means the reference data has been renewed and is current, while a lapsed status means the annual renewal has been missed and the information may be out of date. If a search returns no results at all, the entity may not yet have an LEI, in which case it would need to register one before it can trade in regulated markets. A lapsed record can be brought back to active status through a renewal.
Start Your LEI Search
Searching for a company’s LEI number is fast, free, and straightforward when the right tool is used. With nothing more than a legal name or a code, anyone can confirm an entity’s identity, status, and ownership in seconds. Those ready to find an LEI, verify a counterparty, or check whether a record is active can begin their search through LEI Search.
