Entity Verification - OpenCorporates

How FactSet automated entity matching against official registry data

FactSet has built a model that automatically matches the companies in its database to official registry records on OpenCorporates, as part of a larger strategy to ensure their legal entity data coverage is updated and accurate. It uses software to achieve what a researcher used to do by hand: search for a company, work through the candidates that come back, and identify the one official record that is genuinely the right match. Across several thousand test companies, it reaches match rates of up to around 70 percent, with almost no false positives.

How the Treasury’s Do Not Pay program uses OpenCorporates data to check a business is real before it pays it

On August 18, 2026, the U.S. Department of the Treasury published a one-page notice in the Federal Register titled: Designation of Databases to the Do Not Pay Working System. It marks the moment OpenCorporates data has officially been integrated into the system the federal government uses to decide whether a business should be paid, closing a process opened two months earlier, on the 25th of June 2026, when the Treasury published its proposed designation publicly.

How NICB uses OpenCorporates to detect insurance fraud and verify business legitimacy

Using OpenCorporates' legal entity data covering all North American jurisdictions, NICB has enhanced their fraud detection capabilities, allowing them to verify business legitimacy, track entity relationships, and identify fraudulent patterns. This partnership has also enabled NICB to build a data-driven case for policy advocacy around registry transparency, demonstrating the societal value that open legal entity data provides.

Data / Entity Verification

The registered agent called “Located In”

Every company register insists on a registered agent: a name and a street address where lawsuits and state letters can reach someone who will actually notice. The OpenCorporates API exposes this twice. Once on the company record, as agent_name. Once in the officers list, as whoever holds the agent role. I wanted to see what edge cases of those names, so I searched the officers endpoint for a phrase instead of a person. I typed LOCATED IN. The API came back with two thousand and eleven matches.

The church incorporated in the year one

The other week I was testing a company data API, running harmless searches against Connecticut to see how the search behaved. I asked for companies whose names contain the word "New". Back came the usual spread of LLCs and property vehicles, and then a result that literally stopped me mid-scroll: ST. PETER'S CHURCH OF NEW HAVEN, CONNECTICUT. Company number 0065179. Status: Active. Company type: Special Chartered. Incorporation date: 3 January 0001 (over 2025 years ago).

Seconds vs days: The business impact of automated verification

Every transaction flows through a web of legal entities and regulations. Today, most organizations rely on laborious manual processes to verify legal entity existence. Staff must navigate global government websites and tackle paywalls. They have to create accounts for each new registry, and deal with inconsistent data. This process can take hours or days per entity, creating significant operational drag.
