  • The first four digits represent the identifier of the LEI issuing organisation, otherwise known as Local Operating Unit (LOU).
  • These two digits in the LEI number are always set as 0.0 in every LEI format.
  • This section of the LEI number is unique and identifies each legal entity in the global database with alphanumeric characters.
  • The final two verification digits are generated by an algorithmic formula as described in the ISO 17442 standard.


The Legal Entity Identifier (LEI) is a 20-character alphanumeric code for identifying legal entities worldwide. Each LEI number is unique and exclusive: it is assigned to a company once and may not be assigned to any other company.

The Legal Entity Identifier number does not replace the national registry code of a company.
Since January 3, 2018, legal entities must have a Legal Entity Identifier if they conduct transactions on a regulated market, multilateral facility, or other platforms.

An LEI registration is mandatory for all legal entities that intend to engage in financial market transactions involving any form of securities or derivatives. Examples of such financial instruments include stocks, bonds, ETFs, FX forwards, swaps, and interest rate swaps, among others.
LEI Register will usually assign your Legal Entity Identifier (LEI) number within 24 hours. However, it can take as little as 1-3 hours once we receive the payment and supplementary documents promptly from your company (if required).
The Legal Entity Identifier (LEI) was created after the 2008 global financial crisis to help establish and maintain a global standard for uniquely identifying legal entities that engage in financial transactions.

The LEI system is intended to provide a consistent, globally accepted method for identifying parties to financial transactions to reduce risk and increase transparency in the global financial system.
After issuance, a Legal Entity Identifier (LEI) remains valid for one year. To ensure continued validity, the LEI must be renewed annually. To simplify this process for customers, we offer multiyear solutions allowing extended validity periods without requiring yearly renewals.

Failing to renew the LEI results in its expiration. This can create issues in financial transactions and reporting obligations, potentially leading to financial institutions rejecting transactions and regulatory non-compliance penalties.

An expired, i.e., lapsed LEI can be renewed anytime.
A Legal Entity Identifier (LEI) is a universal, public identifier recognised and valid across all jurisdictions worldwide.
The Legal Entity Identifier (LEI) record is public. It contains information about a legal entity, such as its name, address, ownership structure, and other details that help identify the entity and its relationships with other organisations. It also includes information about the LEI issuer and the status of the LEI.

To see more, visit the LEI search tool.
The Global Legal Entity Identifier Foundation (GLEIF) maintains the Global Index, a publicly available database of all LEIs and their associated entity information. To access GLEIF’s database visit their website or use our search tool.

Simply enter the LEI code or the company’s name associated with an LEI, and the database will provide the current status and other relevant details.
LEI numbers are issued by Local Operating Units (LOUs). LOUs often work in partnership with Registration Agents who do not issue LEI numbers directly but provide valuable assistance to legal entities in the registration, renewal, and transfer process of LEI numbers by undertaking specific tasks.

LEI Register is a Registration Agent of Ubisecure Oy (RapidLEI).
You can switch to a new LEI service provider whenever you wish – the Global LEI System supports healthy competition between issuers and registrars for the benefit of legal entities.

The transfer of an LEI is costless and can be completed within seven days.
LEI applications for Trusts are accepted. If the Trust is not registered with Companies House or Charity Commission, enter “N/A” as the company number.
To obtain an LEI for a Trust, it is necessary to provide supporting documentation that verifies the legal name, legal address, main creation date, and the names of the Trustees.

Such documentation could include a Trust Deed, an establishing agreement, or any other relevant document that confirms the information.
