If you decide to transfer a domain name from one domain name registrar to another, you will need to go through a couple of safety steps. One of them is obtaining a unique EPP code from the present registrar company – provided that you are the domain registrant, since the code is sent to the domain owner’s email address and nobody else can obtain it. You need to provide this code to the new registrar company, otherwise they won’t be able to initiate the transfer process. The EPP codes are case-sensitive and may comprise of digits or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the correct code. As an additional security measure, the transfer authorization code for a domain may be changed on a regular basis. Some companies call this code an Auth key, a domain secret or a domain password as well.
