If you run a company that deals with banks, brokers, payment platforms, or investors, you may have been asked for something called an LEI. It sounds like jargon, and it is easy to dismiss as one more piece of paperwork. But the Legal Entity Identifier has quietly become one of the most widely required business credentials in the world, and understanding what it is takes only a few minutes and saves a lot of confusion later.
The Simple Version
An LEI is a twenty-character code that uniquely identifies your company in financial and regulatory systems worldwide. Think of it as an international passport number for a business. Where your company registration number identifies you inside your own country, the LEI identifies you globally, in a single standardized format that any bank or regulator anywhere can look up. It answers two questions in one code: who is this company, and who is behind it?
The code itself is not random. It links to a public record containing your company’s registered name, address, legal form and, increasingly, its ownership structure. That public, verifiable link is the whole point. It lets institutions confirm they are dealing with the entity they think they are, without chasing paperwork across borders.
Why It Exists
The LEI came out of the 2008 financial crisis. When large institutions collapsed, regulators discovered they could not quickly work out who was connected to whom, because every country and every firm identified companies differently. The Legal Entity Identifier was created to fix that, a single global standard so that a company is identifiable in the same way everywhere. What began as a tool for large financial institutions has spread steadily outward and now reaches ordinary businesses.

Why You Are Being Asked for One Now
The reason more businesses encounter the LEI today is that the situations requiring one keep expanding. Opening certain business bank accounts, trading securities, dealing with investment platforms, taking part in some regulated transactions, and meeting various reporting rules can all trigger the requirement. As financial regulation tightens and cross-border business grows, more institutions simply will not transact with a company that does not have one. If you have been asked, it is usually because a bank or platform on the other side needs it to complete its own compliance.
How Do You Get One
You obtain an LEI through an accredited issuer, or through an agent who works with one, by providing your company details, which are then verified against your national business register. Once issued, the code is valid but must be renewed every year to stay active, and a lapsed LEI can hold up transactions just as a missing one does. The cost is modest, and the process is straightforward, though it is worth using a provider who keeps the renewal active for you rather than leaving you to remember it.
For companies formed in transparent jurisdictions, the verification is quick because the underlying data is already public and reliable. Estonia is a good example where company data is openly available, and an LEI can be issued smoothly against it.
Providers who handle company formation and administration in these jurisdictions, such as Capture, increasingly offer the LEI as part of setting up and running a company, so it is issued and kept current alongside everything else.
The LEI is not going away. If anything, the range of situations that require one will keep growing as financial systems become more connected and more automated. Getting one is a small, inexpensive task, and treating it as a normal part of running a modern business, rather than a mysterious demand, is the right way to think about it.
A Legal Entity Identifier is becoming an essential business credential for companies engaging with banks, investors, and financial platforms. Obtaining and maintaining an active LEI simplifies compliance, supports smoother cross-border transactions, and helps establish trust in today’s increasingly connected global financial ecosystem.
