A new project to create a Global Beneficial Ownership Register

Anonymous, opaque companies enable corruption, fraud, organised crime and tax evasion. That’s why we need a global register of beneficial ownership in the public interest - mapping who controls and benefits from companies.

The register is being created by leading transparency and anti-corruption organisations, and will enable governments to crack down on crime, allow companies to verify who they are really doing business with and empower civil society to investigate and campaign against injustice.


About us

Grand corruption is a networked problem; to fight it we need a networked solution. By linking beneficial ownership data from worldwide corporate registries and other sources, and allowing a clear, consistent mechanism for data collection, the OpenOwnership Register will provide that solution.

A beta version of the Register is now open to the public. Search almost 2 million companies, submit your ownership data, and be sure to leave us feedback.

Alongside the Register, OpenOwnership is developing a universal and open data standard for beneficial ownership, which will provide a solid conceptual and practical foundation for collecting and publishing beneficial ownership data. An initial version of the data standard has now been released.
