Yes, in early 2015 the IE registry (IEDR) introduced an Authorisation Code system for .ie domain transfers.
You can obtain the Authorisation Code for your .ie domain by contacting your current Registrar.
If you are having issues getting the Authcode from your current registrar, you can send a direct request to the IEDRs Registration Services Team by email (firstname.lastname@example.org) – the team will generate the code on your behalf. The Authcode will be sent directly to the email address assigned to the Admin Contact on the domain name. Please note that the IEDR will not give out Authcodes by telephone.
