If you decide to transfer a domain from one domain name registrar to another, you’ll have to pass through several safety procedures. One of them is getting a unique EPP code from the present domain registrar – provided that you are the registrant, since the code is sent to the domain owner’s mailbox and nobody else can obtain it. You will need to provide this code to the new domain name registrar, otherwise they won’t be able to initiate the domain name transfer. The EPP authentication codes are case-sensitive and may include digits or special characters such as commas or dots, which can be easily misentered, so make sure you copy/paste the correct code. As an additional safety measure, the transfer code for a domain name may be altered regularly. Some registrars call this code a domain password, an Auth key or a domain secret as well.
