If you want to transfer a domain from one registrar company to another, you will need a special code, which may be called by various names – an EPP authentication code, an Auth code, a domain password, and so on. All these names denote the same thing – a code that the domain name owner obtains from the present domain registrar and gives to the new one upon ordering. Without a genuine code, a domain name transfer procedure cannot be started and this is one of the security measures against unwanted transfer attempts used with all generic and with most country-code extensions. For even better safety, the code comprises of numbers and/or special symbols and is case-sensitive, so in case you wish to transfer one of your domain names, you need to present the new company with the correct code.
