Today’s financial world is highly interconnected. Companies operate across borders, financial markets tighten regulations, and transparency is no longer optional — it’s expected. In this environment, regulators and financial institutions need reliable ways to identify the organisations they work with. That’s where the Legal Entity Identifier (LEI) comes into play, and why the LEI certificate requirement is now a crucial part of doing business in today’s markets.
In this article, we’ll explain what an LEI is, what the LEI certificate requirement means, who must comply, how you get an LEI, renewal and maintenance, and the real benefits it provides to companies and the global economy.
What Is an LEI? A Clear Identification Code for Businesses
A LEI certificate requirement is a unique 20‑character alphanumeric code used to globally identify a legal entity (such as a company, fund, or institution) that participates in financial transactions. It is not tied to individuals — only to organisations. Wikipedia
This system was introduced to simplify the identification of entities in complicated financial markets and make it easier for regulators, banks, and investors to know who is who and who owns whom in financial dealings. LEI.info
The LEI certificate requirement system is regulated by the Global Legal Entity Identifier Foundation (GLEIF), a nonprofit organisation that works with accredited issuers around the world to allocate and maintain these identifiers. Home – GLEIF
The purpose of having an LEI is straightforward: it enables consistency, clarity, and transparency in financial transactions and regulatory reporting. Without it, matching organisations across different systems, countries, and databases would be slow, error‑prone, and risky.
Understanding the LEI Certificate
When a legal entity obtains an LEI code, the issuing organisation also provides what’s often called an LEI certificate. This document proves, in a clear and official way, that:
- The entity has a valid LEI code
- The code is correctly linked to that specific organisation
- The LEI is active and up‑to‑date
- It includes a record of issue and the expiry date
The LEI certificate is more than just a piece of paper — it is proof of compliance, ready to be shown to regulators, banks, and counterparties when required. id-lei.com
Often the certificate includes a QR code or a link for instant online verification. This makes it easy for stakeholders to confirm the LEI’s validity in real time.
Who Must Have an LEI? The Legal and Regulatory Requirement
Not all companies need an LEI certificate requirement. But for many organisations involved in financial markets, having an LEI is no longer optional — it’s a requirement.
Generally, legal entities must obtain an LEI if they:
- Engage in regulated financial transactions
- Trade or report derivatives in regions like the EU, UK, or US
- Are listed on a stock exchange
- Participate in securities lending or OTC markets
- Need to fulfil regulatory reporting requirements under rules such as MiFID II, EMIR, and similar frameworks
For example, under the European MiFID II and other regulations, investment firms and issuers of traded securities cannot execute or report trades without a valid LEI. help.saxo
In the UK, regulators also require LEIs under national transaction reporting rules, and without one, firms may be unable to act on behalf of clients. FCA
It is key to understand that eligibility for an LEI certificate requirement — meaning the ability to obtain one — is different from legal requirement. Regulators determine where and when it is mandatory. But when a requirement applies, companies must act or risk having financial activity rejected or delayed. LEI.info

How to Obtain Your LEI: A Step‑by‑Step Overview
Obtaining an LEI certificate requirement is a structured process, but it doesn’t take long — and can usually be completed in a few days if all information is provided correctly. Here’s how it works:
1. Choose an Accredited Issuing Body
LEIs are issued by Local Operating Units (LOUs) that are authorised by GLEIF. These units operate globally and follow strict standards in verifying information. Register-LEI UK
2. Fill Out the Application
You will need to provide basic company information, including:
- Official legal name
- Registered address
- Registration number in your home country
- Country of incorporation
This data forms part of the LEI reference data. Register-LEI UK
3. Submit Supporting Documents
Depending on the issuer and your jurisdiction, you may need to provide formal documents confirming your company’s legal status.
4. Pay the Fee
LEI providers charge a registration fee. The cost varies by region and provider, but it typically covers the issuance and first year of maintenance.
5. Receive Your LEI Code and Certificate
Once your application is validated, you’ll receive the 20‑digit LEI code and a certificate confirming its status. This can often be done in 24–72 hours. LEI Register
Renewal and Ongoing Validity
An LEI isn’t a one‑time thing — it must be renewed annually. If you fail to renew, your LEI becomes inactive and may no longer satisfy regulatory requirements.
Inactive LEIs can lead to:
- Blocked or rejected financial transactions
- Inability to submit mandatory reports
- Restrictions on trading and market access
Most issuers will send renewal reminders before your LEI expires, but it’s good practice to mark the date yourself and ensure compliance. investor.help.saxo

Benefits Beyond Compliance
While many organisations initially obtain an LEI because they must, the identifier brings benefits that go beyond mere compliance:
Better Transparency and Trust
LEIs provide readily available public data about organisations, including key reference and ownership information. This helps financial institutions and partners know exactly who they are dealing with. Home – GLEIF
Reduced Operational Risk
With a standard LEI, companies avoid mistakes or mismatches in entity identification, which can otherwise cause costly delays in reporting and transactions. Wolters Kluwer
Easier Regulatory Reporting
Because regulators around the world accept LEIs, businesses with a valid one can submit financial reports more smoothly, avoiding data reconciliation headaches. Crispme
Enhanced Global Market Access
For companies involved in cross‑border trade, an LEI can open doors — enabling them to work with foreign partners and enter markets that enforce these standards. LEI.net
Common Situations Where LEIs Are Asked For
In practical terms, you may be asked to show your LEI or certificate when you:
- Apply for corporate financial services
- Trade on regulated markets
- Submit regulatory filings
- Engage in derivative contracts
- Enter into international trades
Banks, exchanges, and clearing houses increasingly treat LEIs as standard documentation — just like tax IDs or business registration numbers.
Misunderstandings About LEIs
There are a few misconceptions that often confuse business owners:
LEIs Are Not Just for Big Companies
Even small companies can be required to have an LEI if they engage in regulated financial activities. LEI.info
Individuals Don’t Get LEIs
LEIs are strictly for legal entities — companies, funds, trusts, and similar organisations — not individual people. Home – GLEIF
It’s Not a Marketing Tool
Despite sounding like a digital business card, an LEI is a regulatory identifier, not a promotional tool.
Final Thoughts
The LEI certificate requirement represents a practical bridge between regulatory oversight and business transparency in the modern financial world. It ensures that authorities know exactly who is participating in financial systems, making markets more robust, fair, and safe.
For many entities, obtaining and maintaining an LEI code — and keeping the associated certificate current — is now part of the foundations of doing business. It helps prevent fraud, supports global operations, reduces risk, and aligns firms with global standards.
