If you wish to transfer a domain from one domain name registrar to another, you will need to pass through several security procedures. One of them is obtaining a special EPP authorization code from the present domain name registrar – on the condition that you are the domain registrant, since the code is sent to the domain owner’s email and no one else can get it. You’ll have to give this code to the new registrar company, or else they will not be able to begin the transfer process. The EPP codes are case-sensitive and may include numbers or special symbols such as commas or dots, which can be easily mistyped, so make sure you copy and paste the right code. As an extra safety measure, the transfer authorization code for a domain may be changed regularly. Some registrars call this code a domain secret, a domain password or an Auth key as well.
