Renewal of an LEI number

An LEI number needs annual renewal. This means that an LEI issued on 02/01/2018 will have to be renewed before 02/01/2019. If the deadline has passed, your LEI will become inactive until renewed again. This renewal process is necessary to ensure the data in the Global LEI Pool is relevant and up to date.

LEI Register offers the renewal of LEIs for 1-, 3- or 5-year period. Whatever the period, you will receive a notification from LEI Register a month prior to the deadline. In the case of multi-year LEI renewal, the LEI Register will take the responsibility to check your data before renewal and renew your LEI number on a yearly basis. Our aim is to keep your data up to date.

Structure of an LEI number

An LEI number is standardised with ISO certificate 17442. This consists of a combination of 20 numbers and letters.

  • Numbers 1-4 always show the ID of the LOU which has issued the LEI.
  • Numbers 5-6 have always a value of 0.
  • Numbers/Letters 7-18 are unique to each entity.
  • Numbers 19-20 are for verification purposes.
LEI Ireland - What LEI number looks like

LEI number is all about connecting the dots!

The vision of GLEIF is to have one universal registration number for all entities around the globe. This is an identifier that would provide standardised and  high-quality reference data.

"We believe that ultimately there should be one identity behind every business. Having an LEI will help to achieve this objective."

Who can issue LEI numbers?

Issuance of LEI numbers is governed by GLEIF. The GLEIF is the foundation which controls the issuance of LEI codes. The GLEIF does not itself issue LEIs, they are instead issued through a network of public and private companies acting as LOUs. Their purpose is to supply registration, the renewal of LEI codes, and act as a gateway for organisations that wish to obtain an LEI code. A list of LOUs can be found here.

The LEI Registry is not an LOU. Instead, the LEI Registry acts as Registration Agent. Our task is to help companies and public entities obtain reliable information about an LEI, and manage communication between LOUs and entities wishing to apply for an LEI. We check data provided with publically available services such as the Companies Registration Office, etc. More information about Registration Agents can be found here.
