Trade (owner change)


A .hk domain trade is started by filling and signing a trade form, which depends on the type of registrant:

- for companies
- Form - Case 2 _v1.0 - 20.02.04_.pdf for individuals

The signed form can be sent by fax or e-mail to Openprovider. The tracking number in the document can be left blank Openprovider will enter it for you.




An update of a .hk domain is not realtime. Change of registrant is done by the separate trade command.




After the deletion request has been sent to the registry, the domain contacts are notified about this request. The domain contacts have six calendar days to object against this deletion. After those six calender days the domain is put into the so-called 'BlackOut' status for a period of 60 days. This status is only visible via the web-based whois.


Restore (reactivation)


During the 60 days of the BlackOut period it is possible to restore the domain name. Additional fees apply. Contact the Openprovider Support team for more information.
