If you want to transfer a domain name from one registrar to another, you’ll need a unique transfer authorization code, which may be referred to by different names – an EPP authentication code, an AuthInfo code, a domain name password, and so on. All these names refer to the exact same thing – a code that the domain owner obtains from the present domain name registrar and gives to the new one during the order process. Without a valid code, a transfer cannot be started and this is one of the protection mechanisms against unsanctioned transfers used with all generic and with most country-specific extensions. For greater security, the code comprises of numbers and/or special characters and is case-sensitive, so in case you’d like to transfer one of your domains, you have to supply the new domain name registrar with the right code.
