New domain registrations, change in 1. first name, 2. last name, or 3. email address for the Registrant contact will trigger the RAA verification process. Changing just the organization name will not trigger the verification process but a change notice will go out to the registrant email.
The verification email will go to the NEW email address. The changes will not be reflected on the domain name until the RAA email is verified.
This process does not apply to changes to Administrative, Technical, or Billing contacts.
