Frequently asked questions about the Belarus KYB API
What company data can I verify in Belarus?
For a Belarus company, the API returns the company record read live from the Unified State Register: the entity name, type, status, registration number, address, and registration date, along with the available registry documents. See the table above for the full Belarus availability.
Does the API return beneficial ownership (UBO) data for Belarus companies?
For Belarus, the Unified State Register does not publish shareholder or beneficial-owner data, so the API returns the company record and the controlling parties and officers rather than a shareholder or beneficial-owner list. Where you need ownership for an entity in a jurisdiction that does publish it, the recursive org-chart (GET /v2/Companies/{caseCommonId}/org-chart) resolves it. See the UBO API.
Can I retrieve official registry documents for Belarus companies?
Yes. The default document set for Belarus includes Registry Extract, retrieved by default. List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
Is there a free sandbox for testing Belarus company verification?
Yes. The Know Your Customer sandbox at https://api.knowyourcustomer.dev is a free, high-fidelity test environment. Request free sandbox access to start testing.
