Are you an authorized tech contact for your school or school district? At least with PowerSchool SIS those are the only individuals allowed to contact support via phone. We are not allowed to publically list those numbers, so hopefully a forum moderator will be able to assist you further.
Thank you for reaching out in the Community!
Thank you for your quick response @DanM3! Dan is correct for PowerSchool SIS users.
If you are reaching out regarding Unified Talent Applicant Support, I recommend submitting a case with Unified Talent Applicant Support through LiveAssist or email. I have provided the link below to the Applicant Support page.
