- A list of TLDs that support handle updates can be found here.
- If no handle update is possible, you've got to create a new handle and assign it by using the ModifyDomain command. It's not allowed to change: "FIRSTNAME", "MIDDLENAME", "LASTNAME" and "ORGANIZATION" of the Owner Contact by a handle update.
- Please have a look at the "Change of Registrant" section of the related TLD for the appropriate information.
- All owner changes of gTLDs will apply the ICANN_OwnerChange policy starting December 1, 2016.
