If you’d like to transfer a domain name from one domain name registrar to another, you’ll need a unique transfer authorization code, which may be called by multiple names – an EPP authorization code, an Auth-Info code, a domain name password, etc. All these names refer to one and the same thing – a code that the domain registrant gets from the present domain registrar and gives to the new one at the time of the order. Without a valid code, a domain name transfer procedure cannot be initiated and this is one of the safety measures against unsolicited transfer attempts used with all gTLD and with most ccTLD extensions. For greater safety, the code comprises of digits and/or special symbols and is case-sensitive, so if you wish to transfer one of your domains, you need to supply the new company with the right code.
