Frequently asked questions about the China KYB API
What company data can I verify in China?
For a China company, the API returns the company record read live from the National Enterprise Credit Information Publicity System: 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 China availability.
Does the API return beneficial ownership (UBO) data for China companies?
The API resolves the controlling parties, shareholders, and beneficial owners for China 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 National Enterprise Credit Information Publicity System discloses. See the UBO API.
Can I retrieve official registry documents for China companies?
Yes. The default document set for China includes Registry Report, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
