Transferring a domain from one company to another ordinarily entails the use of a special transfer code, which different companies call an EPP authorization code, a domain name password or an Auth code. This code can be used as a safety mechanism against unauthorized transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the domain registrant and is issued by the present registrar. It must be given to the new registrar because the transfer procedure cannot be started without it. The code is case-sensitive and frequently comprises of digits and special characters, so as to obstruct unauthorized persons from hijacking it. Certain registrars even reset the codes of domain names registered through them every now and then for even better security.
