To register a .ie domain you must be able to outline a current Business connection to Ireland.  If registering a .ie domain from outside Ireland, it must be for Business use and not Personal use.  The IEDR will look for a connection with Ireland, for example a copy of an Invoice from your Business to an Irish address.

If you require further assistance with this, please open a ticket with LetsHost New Domain Registrations.  Our Domains team will be able to assist you further.
