If you wish to transfer a domain name from one registrar company to another, you will have to pass through several security procedures. One of them is obtaining a special EPP code from the present domain name registrar – as long as you are the registrant, since the code is emailed to the domain owner’s email and no one else can obtain it. You will have to give this code to the new domain name registrar, otherwise they will not be able to begin the domain name transfer process. The EPP codes are case-sensitive and may contain numbers or special characters such as dots or commas, which can be easily mistyped, so make sure you copy & paste the correct code. As an additional protection measure, the transfer authorization code for a domain name may be reset regularly. Certain registrars refer to this code as an Auth key, a domain secret or a domain password as well.
