In case you want to transfer a domain name from one registrar company to another, you will need a unique code, which may be called by many names – an EPP authorization code, an Auth code, a domain name password, and so on. All these names denote one and the same thing – a code that the domain registrant gets from the current domain registrar and gives to the new one upon ordering. Without an authentic code, a transfer process cannot be started and this is one of the protection mechanisms against unwanted transfer attempts used with all generic and with most country-specific extensions. For even greater safety, the code contains digits and/or special symbols and is case-sensitive, so in case you would like to transfer one of your domains, you need to present the new domain name registrar with the correct code.
