If you wish to transfer a domain from one registrar company to another, you will have to go through a few security procedures. One of them is obtaining a special EPP code from the present domain name registrar – as long as you are the domain registrant, since the code is emailed to the domain owner’s mailbox and nobody else can get it. You have to give this code to the new domain registrar, or else they will not be able to begin the domain name transfer procedure. The EPP codes are case-sensitive and may comprise of numbers or special symbols such as dots or commas, which can be easily mistyped, so make sure you copy and paste the correct code. As an additional safety measure, the transfer authorization code for a domain name may be changed regularly. Some registrars refer to this code as a domain secret, a domain password or an Auth key as well.
