If you wish to transfer a domain from one registrar company to another, you’ll need a unique authorization code, which may be called by multiple names – an EPP authorization code, an Auth code, a domain name password, and so on. All these names designate the exact same thing – a code that the domain owner receives from the current domain name registrar and gives to the new one during the order procedure. Without a genuine code, a domain transfer cannot be initiated and this is one of the safety mechanisms against unsanctioned transfers used with all gTLD and with most ccTLD extensions. For even better security, the code includes digits and/or special characters and is case-sensitive, so in case you would like to transfer one of your domain names, you have to provide the new registrar with the correct code.
