In case you would like to transfer a domain name from one registrar to another, you will need a special code, which may be called by various names – an EPP authorization code, an Auth code, a domain name password, etc. All these names designate the exact same thing – a code that the domain name registrant receives from the present domain registrar and gives to the new one at the time of the order. Without a genuine code, a domain name transfer cannot be started and this is one of the security measures against unsolicited transfer attempts used with all generic and with most country-code extensions. For better security, the code contains numbers and/or special characters and is case-sensitive, so if you want to transfer one of your domain names, you have to supply the new domain name registrar with the correct code.
