In case you wish to transfer a domain from one registrar company to another, you will need a special transfer authorization code, which may be referred to by different names – an EPP authentication code, an AuthInfo code, a domain password, etc. All these names refer to the same thing – a code that the domain name owner gets from the present domain registrar and provides to the new one upon ordering. Without a valid code, a transfer cannot be initiated and this is one of the security measures against unsolicited transfers used with all gTLD and with most ccTLD extensions. For greater security, the code comprises of digits and/or special symbols and is case-sensitive, so if you’d like to transfer one of your domains, you have to supply the new domain registrar with the right code.
