Registered Office Address Dublin

Do You Need a Registered Office Address for Your Company?

Why not use The Mercury Building?
Every company registered in Ireland is required by law to have a registered office in the State. This is the official address where Companies Registration Office (CRO) correspondence, formal notices and legal documents can be sent.

The Mercury Building provides a professional Registered Office Address in Dublin, giving your company a physical Dublin location for its official company correspondence.

What Is a Registered Office Address?
A registered office is the official address of your company recorded with the CRO. It must be a physical location in Ireland and cannot simply be a PO Box.

The address must be capable of receiving official correspondence and documents delivered by post or by hand.

Why Choose The Mercury Building?
Using The Mercury Building as your Dublin Registered Office Address gives your company a professional business location while helping keep your company’s official correspondence separate from your personal or residential address.

Our service can be suitable for:

  • New Irish companies
  • Existing Irish limited companies
  • Startups and entrepreneurs
  • Home-based businesses
  • Remote businesses
  • Companies looking for a Dublin registered office

Keeping Your Registered Office Updated

It is important that your company’s registered office details remain accurate with the CRO.

If your registered office changes, the CRO must be notified using Form B2. The change becomes legally effective once the CRO has registered the notification.

Keeping your registered office details up to date helps ensure that important company correspondence and legal notices reach the correct address.

Professional Dublin Registered Office
The Mercury Building provides a convenient and professional Registered Office Address in Dublin for companies that need a physical Irish business address.

Whether you are establishing a new Irish company or changing the registered office of an existing company, our team can help explain the available options.
