Frequently asked questions about the Hungary KYB API
What company data can I verify in Hungary?
For a Hungary company, the API returns the company record read live from the Igazságügyi Minisztérium: the entity name, type, status, registration number, address, and registration date, along with the controlling parties, the shareholders and beneficial owners, and the available registry documents. See the table above for the full Hungary availability.
Does the API return beneficial ownership (UBO) data for Hungary companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Hungary companies and exposes them as a recursive ownership org-chart (GET /v2/Companies/{caseCommonId}/org-chart), tracing control through holding companies to the individual beneficial owners. The depth available depends on what the Igazságügyi Minisztérium discloses. See the UBO API.
Can I retrieve official registry documents for Hungary companies?
Yes. The default document set for Hungary includes Registry Extract, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
