If you would like to transfer a domain from one registrar company to another, you’ll have to pass through a couple of safety steps. One of them is obtaining a unique EPP authentication code from the present domain name registrar – as long as you are the domain registrant, since the code is emailed to the domain owner’s email address and no one else can obtain it. You will need to give this code to the new registrar, otherwise they will not be able to start the domain transfer procedure. The EPP authorization codes are case-sensitive and may comprise of digits or special characters such as commas or dots, which can be easily misentered, so make sure you copy/paste the right code. As an extra protection measure, the transfer code for a domain name may be altered regularly. Certain registrar companies refer to this code as a domain secret, a domain password or an Auth key as well.
