Frequently asked questions about the Bulgaria KYB API
What company data can I verify in Bulgaria?
For a Bulgaria company, the API returns the company record read live from the ЕПЗЕУ (Commercial Register and Register of Non-profit Legal Entities): 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 Bulgaria availability.
Does the API return beneficial ownership (UBO) data for Bulgaria companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Bulgaria 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 ЕПЗЕУ (Commercial Register and Register of Non-profit Legal Entities) discloses. See the UBO API.
Can I retrieve official registry documents for Bulgaria companies?
Yes. The default document set for Bulgaria includes Registry Extract, retrieved by default, with additional documents available on demand (Current act of establishment, Announced acts (Annual financial report), Company case, Case). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
