Every Sebairo Academy certificate carries a serial. Enter it here and this page will tell you what it belongs to — no account needed.
What this check proves
That the serial was issued by Sebairo, to the person named, for the course named, on the date shown.
A certificate is issued by the server only when every lesson in the course has actually been completed — the app cannot mint one for itself.
This page reads one public function that answers about a serial you already hold. It cannot list certificates, search by name, or reveal anything about the learner's account.
