If you wish to transfer a domain from one domain registrar to another, you will need to pass through a couple of safety procedures. One of them is getting a special EPP code from the present domain name registrar – provided that you are the registrant, since the code is sent to the domain owner’s email and no one else can see it. You’ll need to provide this code to the new registrar company, otherwise they will not be able to start the domain name transfer procedure. The EPP authorization codes are case-sensitive and may include numbers or special characters such as commas or dots, which can be easily misentered, so make sure you copy/paste the correct code. As an additional security measure, the transfer authorization code for a domain name may be changed regularly. Certain registrar companies call this code a domain secret, a domain password or an Auth key as well.
