You can transfer a domain from us to another registrar via your billing account:
For .uk domains you can then enter the new registrar’s IPS tag. Each registar has its own tag (our tag is CATALYST2). The company you are transferring your domain to will be able to confirm its IPS tag.
For other domain names you get an EPP code. To complete the transfer you need to give the EPP code to the new registrar, and they will then be able to manage the transfer.
It is worth noting that the domain registry (i.e. ICANN) will send you an email asking you to confirm you want to transfer the domain. This email is sent to the email address associated with the domain registration. You can check the email address via your billing account:
