Transfer

• A .US Domain Transfer must be initiated with a so-called "Authorisation Code", which can be obtained from the current registrar through the owner or Admin-C of the domain.
• Please ensure, that you have a correct "Authorisation Code" associated with the domain, before initiating the transfer, otherwise it will fail.
• Ensure that your respective domain does not have a lock-status (REGISTRAR-LOCK or HOLD). This can be seen in the WHOIS. If the domain is locked, then the owner can demand that this be unlocked.
• Initiate the transfer on time and not just shortly before the domain expires.
• Please ensure that the domain is older than 60 days otherwise the transfer will be denied.
• Please note that you need a signed request from the registrant before you initiate the transfer.

The transfer of a .US domain will usually take 5-10 days.
