About GLEIF

GLEIF Services



The Global Legal Entity Identifier Foundation (GLEIF) is tasked to manage the only open, non-proprietary entity identification system which is designed as a public good. By doing so, it ensures the operational integrity of the Global Legal Entity Identifier (LEI) System and enables people and businesses to make smarter, less costly and more reliable decisions about who to do business with. GLEIF meets these objectives by offering a broad range of services to the public, e.g. LEI data users, and the partners GLEIF cooperates with such as the LEI issuing organizations. Among other things, GLEIF is responsible for:

  • Evaluating the suitability of organizations seeking to operate as issuers of LEIs.
  • Providing expertise and reliability throughout the organization and management of the system.
  • Ensuring access to the complete global LEI data pool, free of charge, to users.
  • Continuously optimizing the quality of the LEI data pool.
  • Making available comprehensive information on the LEI and the Global LEI System, as well as timely updates on related global developments and GLEIF activities.

The GLEIF Service Catalog, available for download, details the services we provide to both the public and our partners in the Global LEI System.

Entities desiring to become LEI issuing organizations must seek accreditation by GLEIF.

In order to support the integrity of the Global LEI System, an extensive vetting process is in place to ensure that LEI issuing organizations (also referenced as 'Local Operating Units' or LOUs) reflect and incorporate the vision and internal control requirements of GLEIF within their operations.

The Accreditation Manual and Accreditation Checklist (Appendix 02) can be downloaded from GLEIF’s website.

GLEIF’s process of re-verification of the LEI issuing organization's compliance with expected internal controls within its LEI operations.

GLEIF will request from the LEI issuing organization (also referenced as 'Local Operating Unit' or LOU) certain documentation and evidence of compliance with expected internal controls which need to be in place for an accredited LOU to be operational.

This exercise is based upon the current status of internal controls that were verified as part of the LOU’s initial accreditation and as amended in the event under the accreditation change process.

The annual accreditation verification process is executed on or after the anniversary date of the LOU’s date of accreditation as documented on their accreditation certificate.

Using a template provided by GLEIF, the LOU verifies the status of each processing area as mentioned in the Accreditation Checklist. For areas where significant changes have occurred, the LOU documents the nature and extent of the changes and how it/they effected LEI processing. Supporting documentation must be provided as additional information regarding the change(s).

GLEIF reviews this information and assesses the overall impact of any changes noted in the internal controls. GLEIF determines if the changed internal controls still meet the required control standard and advises the LOU as to whether any remediation action is required.

The certification program ensures that organizations which map the LEI to their own identifiers use reasonable methodologies and / or processes to do so accurately.

GLEIF’s Certification of LEI Mapping service evaluates the mapping processes and algorithms applied by organizations seeking to link other identification schemes to the LEI.

Certification, and the subsequent publication by GLEIF of publicly available, open source relationship files which match mapping partner identifiers against corresponding LEIs, eases the process of gathering, aggregating and reconciling counterparty information.

When seeking certification, the mapping partner documents the nature and extent of the mapping methodologies and / or processes. This enables GLEIF to review the processes and procedures, validate sample data from the mapping partner and determine if the sample data meets or exceeds GLEIF’s pre-determined accuracy and quality criteria. In cases where it does, GLEIF certification is confirmed.
