Ireland company register API - CRO
Query the CRO by company number or name and get the Irish register entry as JSON - identity, status, incorporation date, registered address and the annual return cycle. The return date is the field worth watching: materially overdue is an early signal.

CRO (Companies Registration Office)
The Companies Registration Office is the Irish statutory company register. It holds company identity and status, incorporation date, registered address and the annual return cycle, keyed off the CRO number.
Irish CRO records are comparatively rich on the fields that matter for outreach and monitoring at once - registered address, incorporation date and annual return status all come from the same entry.
We read the register and return that entry as structured JSON.
What is a CRO number?
The company registration number issued by the Irish Companies Registration Office on incorporation. It is the primary key for looking a company up.
What does the annual return date tell me?
It shows whether a company is current with its statutory filings. A materially overdue annual return is a standard early signal of a company that has stopped being actively administered.
Is Irish company data free?
Core company information is publicly searchable through the CRO. Filed documents are charged for individually, and the search itself is interactive rather than programmatic.
