In case you wish to transfer a domain from one domain registrar to another, you will need a unique domain authorization code, which may be called by multiple names – an EPP authentication code, an AuthInfo code, a domain password, etc. All these names designate the exact same thing – a code that the domain name registrant gets from the current domain registrar and provides to the new one upon ordering. Without a genuine code, a domain name transfer procedure cannot be initiated and this is one of the protection mechanisms against unauthorized transfers used with all generic and with most country-code extensions. For greater security, the code comprises of digits and/or special symbols and is case-sensitive, so if you would like to transfer one of your domain names, you need to supply the new registrar company with the right code.
