In case you wish to transfer a domain from one registrar to another, you will need a unique transfer authorization code, which may be referred to by various names – an EPP authentication code, an Auth code, a domain name password, etc. All these names designate one and the same thing – a code that the domain registrant gets from the current domain name registrar and provides to the new one at the time of the order. Without an authentic code, a domain transfer cannot be started and this is one of the protection measures against unauthorized transfer attempts used with all generic and with most country-code extensions. For even better security, the code contains digits and/or special characters and is case-sensitive, so in case you would like to transfer one of your domain names, you need to present the new domain registrar with the correct code.
