Frequently asked questions about the Ireland KYB API
What company data can I verify in Ireland?
For a Ireland company, the API returns the company record read live from the CORE: 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 Ireland availability.
Does the API return beneficial ownership (UBO) data for Ireland companies?
The API resolves the controlling parties, shareholders, and beneficial owners for Ireland 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 CORE discloses. See the UBO API.
Can I retrieve official registry documents for Ireland companies?
Yes. The default document set for Ireland includes Certificate of Incorporation, B1 Annual Return, Company Constitution, A1 Application to Register as a New Company, retrieved by default, with additional documents available on demand (Letter of status – Companies, Duplicate Cert – Certificate of Incorporation of Company, Company Printout, Last Months Statement, Short Certificate (Public Service use only), Short Certificate for Business Names (Public Service use only), and more). List and download them with the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
