If you would like to transfer a domain from one registrar to another, you’ll need a unique transfer code, which may be called by multiple names – an EPP authorization code, an Auth-Info code, a domain name password, etc. All these names denote the same thing – a code that the domain name owner receives from the present domain name registrar and gives to the new one upon ordering. Without a valid code, a domain name transfer cannot be started and this is one of the safety mechanisms against unsolicited transfers used with all gTLD and with most ccTLD extensions. For better safety, the code comprises of digits and/or special characters and is case-sensitive, so in case you would like to transfer one of your domains, you have to provide the new company with the right code.
