Frequently asked questions about the Vietnam KYB API
What company data can I verify in Vietnam?
For a Vietnam company, the API returns the company record read live from the National Business Registration Portal and General Department of Taxation: 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 Vietnam availability.
Does the API return beneficial ownership (UBO) data for Vietnam companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Vietnam 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 Business Registration Portal and General Department of Taxation discloses. See the UBO API.
Can I retrieve official registry documents for Vietnam companies?
Yes. The default document set for Vietnam includes Registry Extract, retrieved by default, with additional documents available on demand (Historical Registry Extract, Business Certificate). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
