dotPH, the central registry of .PH requires that a registrant is set when a domain is registered. This registrant cannot be changed later through the Dynadot control panel.

Instead, you must fill out a change of ownership form and submit it to dotPH. The modification is currently free, although dotPH may change this in the future.

If you want to change the email contact associated with the .PH domain, you will also need to fill out the form.
