We are the ‘Company registry’ for the world, open for everyone

Public official, legal entity data

All our data comes from primary public sources – we don’t buy any third-party data, and are transparent about – meaning users can rely on OpenCorporates data.

Data at scale

We are the largest open database of companies in the world. We have 190+m companies from 140 jurisdictions, all brought together into a standardised global schema.

Open identifiers

Unlike the traditional ‘black-box’ data providers, OpenCorporates provides open (non-proprietary) identifiers based on the identifiers issued by the official source.

Full provenance

We’re clear about where we got our data, and when we got it, unlike the ‘black-box’ data of the traditional proprietary providers.

Direct from source

We only collect data from the official source itself, we do not use third party data providers to access this data, and we provide direct line of sight to the original source.

Tech driven

Combined with the above principles, our custom-built data collection, QA and reconciliation technology gives us a significant competitive advantage over legacy business information companies.

White Box Data

OpenCorporates’ is the world’s leading source of White Box company data. For 50 years, the data industry has been dominated by "Black Box data" – opaque, not well-defined, no provenance, using proprietary identifiers, and with poor data-quality feedback loops. Now, in a data-centric world, this is no longer fit for purpose, and what is needed is White Box Data – clearly defined, full provenance, open IDs, and available publicly for the best high-quality feedback loops.
