Check an Irish company by API: CRO open data

Companies Registration Office (CRO) · read from the national register · checked 11 November 2026

The official route

The Companies Registration Office (CRO) has its own open-data portal. The dataset "Company Records" is a daily snapshot of every company, live and dissolved. You query it through the portal's CKAN datastore API without a key:

https://opendata.cro.ie/api/3/action/datastore_search

Each record has the company number, name, status, type, registration date, address and the dates of the last annual return and accounts. The dataset page (read 2026-11-09) says it is available under CC BY 4.0. The CRO asks you to include or link to this statement: "Contains Irish Public Sector Data licensed under a Creative Commons Attribution 4.0 International (CC BY 4.0) licence". The portal publishes no rate limit.

Where it gets hard

It is a snapshot, so a record can be up to a day old.
Receiverships are not in the dataset. The status word covers things like Normal, Liquidation, Examinership, Strike Off Listed and Dissolved.
There are no directors and no secretaries in it.
The CRO's financial-statements dataset is separate. When we queried it, it held filing metadata such as the PDF file name and dates, and no figures.
The older API on services.cro.ie answers 401 without an account.
