Frequently asked questions about the Singapore KYB API
What company data can I verify in Singapore?
For a Singapore company, the API returns the company record read live from the CRIF BizInsights: 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 Singapore availability.
Does the API return beneficial ownership (UBO) data for Singapore companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Singapore 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 CRIF BizInsights discloses. See the UBO API.
Can I retrieve official registry documents for Singapore companies?
Yes. The default document set for Singapore includes Business Profile, retrieved by default, with additional documents available on demand (Enhanced Business Profile (EBPF), Comprehensive Business Profile (CBPF), Basic Essential Corporate Information (ECI), Enhanced Essential Corporate Information (EECI), Comprehensive Information (CCI), Strategic Corporate Information (SCI), and more). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
