Registry Lookup
Look up a company across global registries with one query. Returns the LEI, SEC CIK, UK Companies House, French SIREN, German HRB, Dutch KvK, OpenCorporates ID, and more — wherever the entity is registered.
Why this exists
Cross-border M&A starts with a registry check. The same target shows up under a German HRB number in Berlin, an HMRC entity reference in London, an OpenCorporates ID at the corporate level, and an LEI everywhere a financial transaction touches it. Most diligence teams open seven browser tabs to assemble that picture. This tool does it in one query.
The data lives in Wikidata, the structured-knowledge layer of Wikipedia. For any company notable enough to have an entry — most public companies, large privates, and major non-profits — Wikidata aggregates the registry IDs across jurisdictions and exposes them via a open API.
Frequently asked questions
What does Registry Lookup do?
Registry Lookup verifies a company across 27+ national business registries — UK Companies House, French SIREN, German HRB, Dutch KvK, Belgian KBO, OpenCorporates, and SEC CIK among them — using a single search. It returns the canonical registry IDs for any company on the global registry network, so you can cross-reference deal-room representations against the actual filings.
Where does the registry data come from?
All identifiers are sourced from Wikidata, which aggregates official registry IDs from each country's company-house equivalent. For each match, the tool surfaces the underlying Wikidata Q-item and direct links to the upstream registry pages. Wikidata is community-maintained but cross-referenced against the official registries it pulls from.
Who should use Registry Lookup?
Cross-border M&A deal teams, KYC analysts, finance and legal teams running counterparty diligence, and journalists tracing corporate structures. Any time the question is 'is this entity registered, where, and under what name' — without seven open browser tabs.
