What this directory is
Who in Ireland is a free, public directory of service companies registered with the Companies Registration Office (CRO) in Ireland. Each profile shows the legal name, CRO company number, registered county and, where the company publishes them on its own website, a short description of what it does, its phone number and a link to its site.
It exists because the official register tells you that a company exists, but not what it does. We join the two: the register for the facts, the company's own website for the story. Read how the data is gathered or claim your company's listing.
