LEI System

LEI codes aren’t only used for securities trading.

A company may also need an LEI when raising money through an EU-regulated crowdfunding platform.
In lending-based crowdfunding, for example, the LEI is used to identify a legal entity acting as the project owner in regulatory reporting.

In our latest article, we explain how this works, when an LEI is needed and why a crowdfunding platform may ask a company for one.

What happens if your company has the same or a very similar name as a company on a sanctions list?

Your company may have nothing to do with the sanctioned company. But a screening system may still find a match based on the name alone.

This is where the LEI can help.

A company name tells you what a company is called. An LEI helps identify exactly which company it is.
In our latest article, we look at how LEIs can help distinguish between similarly named companies, reduce false positives, and improve sanctions screening.

What does LEI Level 2 actually tell us about a company? 🔍

GLEIF describes LEI data through two simple questions:

Level 1: “Who is who?”
Level 2: “Who owns whom?”

But “Who owns whom?” is not quite as simple as it sounds.

LEI Level 2 is not a list of shareholders or beneficial owners. Instead, it shows parent relationships based on accounting consolidation, helping connect companies that may be registered in different countries.

This gives a broader picture of where a legal entity sits within a corporate structure. 🌍

But why do some companies have no parent listed? And what do terms like NATURAL_PERSONS, NO_LEI and NON_PUBLIC actually mean?

Our latest article explains LEI Level 2 in simple terms, with real company examples.

🏦 Your bank asks for an LEI.
📈 Your broker requires one.
📋 A regulation says you need one.
🔄 And every year, you are told to renew it.

LEI, LEI, LEI.

But have you ever wondered why the LEI system exists in the first place, and what actually happens behind those three letters?

The Legal Entity Identifier is much more than just another company identification number. The global LEI system grew out of the lessons of the 2008 financial crisis and today connects regulators, GLEIF, Local Operating Units (LOUs), Registration Agents, and businesses around the world. 🌍

We put together a simple guide explaining the whole LEI ecosystem:
🔎 Where did the LEI system come from?
🏛️ Who is behind it?
🔗 How do GLEIF, LOUs and Registration Agents fit together?
⚙️ How does an LEI application actually work?
🌐 Why is LEI used in financial regulation around the world?

If you have ever needed an LEI but never really stopped to ask why the system exists or what happens behind the scenes, this article is for you.

AI agents are already paying for things online. No person clicking "buy," no one confirming the purchase.

Visa, Mastercard, Google, and Stripe have all built the rails for this already. Visa has Intelligent Commerce, Mastercard has Agent Pay, Google has its Agent Payments Protocol, and Stripe powers Instant Checkout inside ChatGPT.

Sounds convenient, until you ask: who is actually responsible if something goes wrong?

GLEIF, the organization behind the global LEI system, just proposed an answer. It is called an Agent Mandate Credential, and it ties every AI agent's spending power back to a real, verified company identity.

Still early days. Still just a proposal. But one thing is already true: if your company's LEI record is outdated, any trust system built on top of it starts on shaky ground.

We break it all down on the blog.

🧾 If your company operates internationally, applies for credit, files taxes, or trades financial instruments, you've probably run into an alphabet soup of identifiers: LEI, ISIN, DUNS, EIN, UEI, GIIN, VAT number, company registration number.

They often show up on the same forms. They sound alike. More than one accountant has mistakenly sent a bank a DUNS number instead of an LEI code. 😅
Eight completely different systems, each issued by a different body, each unlocking a different door: tax filing, credit checks, securities trading, US federal contracts, cross-border invoicing.

We broke down who issues each one and when your business actually needs it

📉 On 11 October 2027, the EU moves to T+1 settlement. When you buy or sell a security, the cash and the securities change hands one working day after the trade, not two.

⏳ Shorter is better in most ways. Less time between trade and settlement means less counterparty risk. But it also takes away the spare day firms used to fix a mistake before it settled.

🔍 Clean counterparty data was always needed. The difference now is that there's half as much room to catch an error. A wrong identifier or a company name spelled two ways is enough to make a trade fail.

🔗 The LEI is the standard way to keep that data clean across the chain. It ties each trade to the right legal entity, the same way in every system and every country.

✅ ESMA has said 2026 is the year to get ready.
We wrote up what changes and what to check now:

🌍 Why would a company need an LEI if its own country does not require one?

🤝 Because the other side of the deal requires it. If you want to trade securities through an EU-regulated broker, for example, the broker needs your LEI to report the trade. Without it, the trade does not go through.

✅ And it is not only the EU. Similar rules apply in the US, India, and Mexico. The good news is that one valid LEI covers all of them at once.

📌 We put together an overview of what has changed in 2026 and what is still coming, with the dates and who each rule affects.

🔑 Your company's LEI code is starting to open doors well beyond the financial world.

In July 2026, GODIN, GLEIF's open data network, gained three new members, including Wikimedia Deutschland, the developer of Wikidata. The network connects business registers, supply chains, and open knowledge bases through a single key: the unique LEI code of each company. 🌍

Why does this matter? 🤖 AI systems like ChatGPT, Claude, and Grok draw their data from open sources like these. The more deeply the LEI code is embedded, the more reliably artificial intelligence identifies your company correctly.

A valid LEI code is no longer just a reporting requirement. It is your company's digital identity. ✅

Is your company planning to trade securities? Banks and trading platforms require a valid LEI code from legal entities when opening a securities account.

Without one, transactions simply cannot go through —
No LEI, no trade.

The good news is that registering an LEI takes just a few minutes. Read more on our blog. 👇
