Every set of characters in this code has a meaning attached to them, so they are not randomly generated characters as most people might think. In this article, we will help you understand the structure of a legitimate LEI code to make it easy for you to interpret it once you come across one.

Attributes of an LEI code

  1. It is unique: Any specific LEI code belongs to only one entity and cannot be issued to another. If you come across any two companies with a similar LEI code, it simply means one of these two is not legitimate.

  2. It is an international standard: An LEI code is recognized internationally, so it can be used to identify your entity in any part of the world.

  3. An LEI code is a public good: Unlike some other registration details of an entity, an LEI code is available for the public to view. Once an entity is registered into the Global Legal Entity Identifier (LEI) System, its LEI code is published right away for the entire public to see. The information published alongside this code includes; the official name of the legal entity, its registered address, country of formation, the date of the first LEI assignment, date of the last update of the LEI information, and the expiry date of the current one (if applicable).

  4. An LEI code is supported by quality data: Besides the code itself, all the basic information about the company is published along with the code.

LEI Number Format

So, what do these characters in the code represent?

  1. The first four characters: Represent the Local Operations Units (LOU) that issues the LEI code to the company. This is to ensure uniqueness among codes issued by the same LEI issuer.
  2. Character 5 to 18: These characters represent a unique alphanumeric string issued to an organization by the LOU. So, this string of characters cannot be the same for entities under the same LOU.
  3. The last 2 characters: Represent the checksum digits.
