Entities rely on their legal entity identifier worldwide to participate confidently in markets. Insights on ownership and structure are provided.
In the world of financial transactions and global business, trust and transparency matter more than ever. When entities interact across countries, platforms, and regulatory frameworks, authentic identification forms the foundation of a robust and stable market. This is exactly where the Legal Entity Identifier, or LEI, steps onto the stage.
The LEI system is more than just another regulatory checkbox. It presents a universal solution, aiming to bring clarity to the increasingly complex world of entity recognition. Thousands of organisations worldwide rely on their LEI to assert their identity reliably and participate confidently in financial markets.
What is a Legal Entity Identifier?
A Legal Entity Identifier is a 20-character, alphanumeric code that uniquely identifies legal entities participating in financial transactions worldwide. Created under the guidance of the Global Legal Entity Identifier Foundation (GLEIF), the LEI acts as an international reference number.
Imagine this as a digital passport for businesses, funds, trusts, or even governmental organisations. Once issued, this LEI becomes the golden thread linking an entity to a standardised and searchable global database, offering insights about its structure and ownership.
The need for this standard arose from the 2008 global financial crisis. Regulators and markets understood that opaque ownership structures and complex entity relationships hampered their ability to monitor systemic risks. With the introduction of the LEI, greater transparency became a reality.
How the LEI System Works
Securing an LEI is refreshingly straightforward. Entities apply through accredited Local Operating Units (LOUs) or via professional LEI registration agents. After verification, the issued code is added to the global LEI database, associating it publicly with the entity’s verified data.
The data connected to each LEI is split into two layers:
Level 1 Data: Answers the question “who is who?” by recording basic details such as the entity’s legal name, address, country of formation, and legal form.
Level 2 Data: Addresses “who owns whom?” capturing information about parent companies and controlling interests where applicable.
Here’s a simplified example to illustrate the structure:

Why the LEI Matters
Markets thrive when players trust one another and regulatory authorities can ensure smooth, legal transactions. The LEI was created to bolster this trust.
Key benefits:
Transparency – Each LEI is linked to public, verified information about its holder. This reveals corporate hierarchies that might otherwise remain hidden.
Risk Reduction – Reliable identification helps financial institutions and regulators spot potential risks in interconnected financial systems.
Operational Efficiency – Institutions can streamline compliance checks, speed up client onboarding, and avoid duplication of entity verification efforts.
Regulatory Compliance – Many jurisdictions now require an LEI for participating in specific financial transactions, particularly involving securities, derivatives, and reporting obligations.
Global Consistency – A unified standard eliminates confusion over local identifiers, enabling easier cross-border operations.
These advantages explain why adoption has snowballed, with millions of active LEIs today.
Who Needs an LEI?
LEIs are not compulsory for everybody, but many types of organisations now require them by law.
Entities commonly requiring an LEI:
Companies listed on exchanges or trading in securities
Banks and investment funds
Insurance companies
- Pension funds
- Trusts, partnerships, and foundations
- Governmental bodies engaging in financial transactions
If your organisation engages in transactions subject to MiFID II, EMIR, SFTR, or similar regulations, holding an active LEI is non-negotiable.
How to Obtain an LEI
Registering for an LEI is designed to be accessible and efficient. The process often includes:
- Collecting Key Data: Legal name, registered office address, company registration number, legal form, and (if relevant) information about parent entities.
- Choosing a Registration Provider: This could be an accredited LOU or a registration agent. One popular agent in the UK market is leiservice.co.uk, which can help simplify the process.
- Submitting the Application: Responsible parties provide accurate information, complying with documentation requirements.
- Verification and Issuance: The submitted data is checked against official registries before the LEI is granted.
LEIs are valid for one year and require annual renewal. Failing to renew means the LEI becomes lapsed and may be rejected during transactions.
LEI in Practice: Where It’s Used
The LEI has carved out a vital place across various markets. Its uses extend well beyond securities trading:
- Transaction Reporting: Banks and asset managers use LEIs when reporting transactions to regulators, ensuring accuracy.
- Client Onboarding: KYC (Know Your Customer) checks are often accelerated as LEIs provide instantly verifiable identification.
- Cross-Border Payments: Payment networks, especially those operating internationally, use LEIs to reduce ambiguity.
- Anti-Money Laundering (AML): Linking transaction parties to verified entities helps in tracking illicit activity.
- Audit and Reconciliation: The ability to reliably match parties aids accountants, auditors, and risk officers.
Regulators lean heavily on the LEI to oversee markets and enforce accountability. Financial institutions in turn trust that transacting parties are exactly who they claim to be.
Common Misconceptions
Despite its role as a universal identifier, several misunderstandings surround the LEI.
- An LEI is not a credit rating: It doesn’t guarantee financial health or creditworthiness. Rather, it’s a neutral reference point.
- Sole traders and individuals aren’t eligible: Only registered organisations and legal structures can obtain an LEI.
- The LEI is not the same as a VAT or company registration number: It’s a distinct code, globally recognised beyond national borders.
- It isn’t a one-time requirement: Annual renewal ensures the connected data stays up to date.
The Broader Impact
Widespread LEI adoption marks a shift towards openness in financial dealings. While initially focused on financial services, the code is making inroads into new sectors. For example, shipping, supply chain management, and even insurance claim processing now reference LEIs to cut down on fraud and misunderstanding.
As digital transformation continues, the LEI also fits neatly with advances in electronic signatures, digital identity checks, and emerging technologies like blockchain. By acting as a globally consistent reference for entities, it helps build a fabric of trust that modern infrastructure depends on.
The Future of the LEI System
The LEI initiative is still gathering pace. Ambitions run high. Global authorities have explored embedding LEI checks into more business processes, pushing for adoption in banking, procurement, digital contracts, and beyond.
Calls to digitise and automate financial systems, integrate artificial intelligence, and facilitate instant cross-border payments all highlight the need for a single identifier. As the backbone for credible identity in these scenarios, ongoing investment in the LEI system is looking like a wise choice.
Market participants who embrace the LEI early often find competitive advantages in smoother onboarding, fewer regulatory headaches, and stronger digital operations.

Getting Ahead with LEI
As regulatory scrutiny grows and transparency continues to shape the markets of tomorrow, adopting the LEI is more than a simple compliance task. It signals a commitment to openness and global citizenship, smoothing the path for international business and financial opportunity.
Whether your institution is entering new product markets or looking to streamline cross-border operations, the LEI is becoming a key asset.
Forward-thinking organisations who integrate LEIs into their processes today will be better placed to thrive in markets that value trust, precision, and accountability.
