If you want to transfer a domain from one company to another, you will need a unique domain name authorization code, which may be called by different names – an EPP key, an Auth code, a domain password, and so on. All these names refer to the same thing – a code that the domain name owner receives from the present registrar and provides to the new one during the order procedure. Without an authentic code, a transfer cannot be started and this is one of the security measures against unsanctioned transfer attempts used with all generic and with most country-code extensions. For greater security, the code contains digits and/or special characters and is case-sensitive, so in case you want to transfer one of your domains, you need to present the new domain name registrar with the right code.
