If you decide to transfer a domain name from one domain name registrar to another, you’ll have to go through a couple of safety procedures. One of them is getting a unique EPP code from the current domain name registrar – as long as you are the registrant, since the code is emailed to the domain owner’s email address and no one else can get it. You need to provide this code to the new domain registrar, otherwise they will not be able to initiate the domain transfer procedure. The EPP authorization codes are case-sensitive and may comprise of digits or special symbols such as dots or commas, which can be easily mistyped, so make sure you copy and paste the right code. As an additional security measure, the transfer authorization code for a domain name may be altered regularly. Some registrars refer to this code as a domain secret, an Auth key or a domain password as well.
