In April 2023, the Global Legal Entity Identifier Foundation (GLEIF) and OpenCorporates announced the first open source relationship file that links corresponding records in OpenCorporates’ global database of legal entity data, to its Legal Entity Identifier (LEI).

Both organizations are uniquely focused on ensuring that open and reliable entity reference data is publicly available to promote transparency and increase trust in the business environment and simplify and reduce the cost of customer and third-party management. Open, public, high quality, and electronically accessible company data is critical to address the hidden risks in financial markets and global supply chains, as well as tackling money laundering and the criminal use of companies, particularly as business operations become more automated.

OpenCorporates is the world’s foundational source for legal entity data and is on a mission to bring about genuine corporate transparency, and has been instrumental in opening access to corporate registries across Europe and North America, as well as being the largest open database of companies in the world, containing more than 220 million companies and 300 million officers from 145 jurisdictions (as at early 2023). Its data is fully provenanced to official sources, unified according to a global schema, up-to-date, and available at scale.

Data users, including financial institutions, government agencies, and companies, will benefit significantly from these complementary datasets being linked. With LEIs now natively available in the OpenCorporates database, cross-referencing between these two datasets will facilitate a wide range of compliance, surveillance, and due diligence monitoring processes.

The collaboration delivers the following benefits to global data consumers:

• Extended information about businesses. Data users can leverage the LEI to seamlessly connect to the OpenCorporates dataset and vice versa. LEI data answers the question of ‘who owns who’, including verified parent and subsidiary relationships, while the OpenCorporates database of corporate registry records contains foundational company information, such as current status, named directors, and industry codes.
• Streamlined data management. The addition of the LEI to the identifiers held in the OpenCorporates database, alongside the addition of OpenCorporates to a growing number of other identifiers already mapped to the LEI, helps to streamline entity reconciliation processes and, in turn, reduce data management costs.
• More effective and efficient risk analysis. Understanding a group’s corporate structure from verified LEI data, together with access to a richer linked dataset, supports a variety of other risk requirements, such as counterparty exposure, for example.
• Easy integration of wider datasets. Many wider datasets already utilize either the OpenCorporates or LEI identifiers (such as the OECD-UNSD Multinational Enterprise Information Platform or wider supply chain, beneficial ownership, sanctions, and many Know-Your-Customer and anti-financial crime platforms). This collaboration will allow commercial organizations, fintech firms, and those working for the public benefit to increase innovation and insights by joining data together.

The OpenCorporates ID-to-LEI relationship is built upon a mapping process established by GLEIF. It is published in CSV format and will be updated on a bi-weekly basis. More than 50% of the global LEI population is now linked to the OpenCorporates database (given not all legal entities with LEIs are officially registered - e.g., funds).
