If you want to transfer a domain from one registrar to another, you will need a unique transfer authorization code, which may be called by many names – an EPP authentication code, an Auth code, a domain password, etc. All these names refer to the very same thing – a code that the domain owner gets from the present domain name registrar and gives to the new one during the order process. Without an authentic code, a domain transfer procedure cannot be initiated and this is one of the security measures against unsanctioned transfer attempts used with all generic and with most country-specific extensions. For even better security, the code includes numbers and/or special characters and is case-sensitive, so in case you want to transfer one of your domain names, you need to provide the new domain registrar with the correct code.
