Our Nominet registrar tag is:
PDR-IND
This is also sometimes called the Nominet tag, IPS tag, or registrar tag.
Use this tag when transferring a UK domain such as .co.uk, .org.uk, .me.uk, or .uk to 4UHosting.
Important: Submit the transfer request with us before asking the current provider to change the tag. Our system needs to know it is waiting for the tag change to come in.
