If you want to transfer a domain from one domain name registrar to another, you will need to pass through a couple of safety procedures. One of them is obtaining a unique EPP code from the current registrar company – on the condition that you are the domain registrant, since the code is sent to the owner's email account and no one else can see it. You need to provide this code to the new registrar company, or else they will not be able to initiate the transfer process. The EPP authorization codes are case-sensitive and may contain digits or special characters such as dots or commas, which can be easily misentered, so make sure you copy and paste the correct code. As an additional protection measure, the transfer code for a domain may be changed regularly. Certain registrars call this code an Auth key, a domain secret or a domain password as well.
