TLD specific

Restrictions

Registrants of TW Domains must comply to the General Terms and Conditions of .TW Domains:

• Supervision and Guidance Regulation for Internet Protocol (IP) Address and Domain Name Registration and Management Services currently at twnic's site.
• Guidelines for Administration of Domain Name Registration currently at twnic's site.
• Guidelines for Authorisation of Domain Name Registration Services, currently at twnic's site.

Transfer

Transfer notes:

• A .TW Domain Transfer must be initiated with an "Authorisation Code", which can be obtained from the current registrar through the owner or Admin-C of the domain.
• 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 .TW domain will usually take 5-7 working days.

RegistrarOC

Restore Process

To restore a domain as a RegistrarOC customer, you simply have to execute the RestoreDomain command. HEXONET directly forwards the restore request to the registry, which performs the restore in real-time. As soon as the restore is complete, the domain will get assigned to your account with the original domain data.

Please do not initiate a restore directly at the registry (e.g. using the registrar webinterface). All restore operations must be performed through our system.
