If you wish to transfer your current domain to another provider you will need your EPP Code, some providers call this an Auth Code or Domain Password.
At Constructive Visual we call this an EPP Code, please note you only need this if you wish to take your domain to another domain registrar, as it is only used to transfer a domain.
If you still wish to transfer your domain from Constructive Visual, you can login to "Client Login" using your email address and password.
Under "My Domains" select the domain you wish to transfer, scroll to the "Management" section, then press "Get EPP Code"
Your EPP code will be displayed along with instructions on how it's used.
