If you’d like to transfer a domain from one domain registrar to another, you will need a unique authorization code, which may be referred to by multiple names – an EPP key, an Auth code, a domain name password, etc. All these names designate the same thing – a code that the domain registrant gets from the current registrar and provides to the new one during the order process. Without a valid code, a domain name transfer procedure cannot be started and this is one of the protection mechanisms against unapproved transfers used with all generic and with most country-specific extensions. For even better security, the code contains numbers and/or special characters and is case-sensitive, so in case you want to transfer one of your domain names, you need to supply the new company with the correct code.
