Direct answer
Every file a student sends to Turnitin is logged under its own numeric reference, and Turnitin calls that reference the Submission ID. It points to one specific upload inside one specific class and assignment — it is not a score, a grade, or a guarantee that a report has been released to you. Knowing exactly what this identifier does, and what it cannot unlock, is the quickest way to confirm the status of your own paper. [1]
Introduction
Every file a student sends to Turnitin is logged under its own numeric reference, and Turnitin calls that reference the Submission ID. It points to one specific upload inside one specific class and assignment — it is not a score, a grade, or a guarantee that a report has been released to you. Knowing exactly what this identifier does, and what it cannot unlock, is the quickest way to confirm the status of your own paper. [1]
What Is a Turnitin Submission ID, and Where Do I Find It?
A Submission ID is a unique numeric string that Turnitin generates the moment a file is accepted into an assignment, and it stays attached to that single upload for the life of the record. It is deliberately different from the class ID and the assignment ID, which describe the container your paper sits inside rather than the paper itself. Because it is issued per submission, uploading a revised draft produces a new ID rather than replacing the previous one. [2]
Where you actually see it depends on how you handed the work in. Students submitting through an institutional Feedback Studio dropbox usually find the number on the digital receipt that Turnitin emails after a successful upload, alongside the class and assignment details. Instructors see the same identifier listed against every paper in the assignment inbox, which is what makes it useful for matching a student query to a specific file. [2]
Instructors and administrators may also encounter the ID in bulk exports of the assignment, where each row corresponds to one submission rather than one student. That is why a student who submitted three drafts of the same essay will appear three times, each with its own distinct ID. Turnitin's student-facing guidance therefore treats the Submission ID as a record label, not as a link to a report. [2]
One practical caution: the number on a Turnitin digital receipt is not the same thing as a Similarity Report ID or an AI writing detection figure. If your receipt shows an ID but your class has report viewing disabled, you will still not see a percentage — the two things are controlled separately. Keep the receipt until your grade is returned, since it is the cleanest proof that your file was received at a given time. [2]
FAQ
Does every Turnitin submission have its own Submission ID?
Yes. Turnitin issues a separate numeric ID to each accepted upload, so re-submitting a revised draft creates an additional record rather than overwriting the first one. This is why instructors can see several IDs for the same student in one assignment. [2]
Can my instructor find my paper using my Submission ID?
Instructors do not need it — they already see every submission ID listed against each paper in the assignment inbox. Quoting the ID is still helpful when you ask a question, because it lets staff locate the exact file you mean instead of guessing. [2]
Why is my Submission ID different from my class ID?
The class ID identifies the module or course space, and the assignment ID identifies the task inside it, while the Submission ID identifies your individual paper. Turnitin keeps the three separate so a report, a grade and a file can all be traced independently. [1]
Can I share my Submission ID with another student?
You can share the number, but it cannot be used to open your report. Report visibility is controlled by class settings and requires legitimate access to that class, so an ID is not a lookup key for someone else's paper. [3]
Do I get a Submission ID if I check a draft with turnitin0?
You get the substantive output of a check: a similarity report and a Turnitin AI detection report matching what instructors see, delivered in about 10 minutes in most cases. The purpose is to see your scores and flags before the real deadline rather than to reproduce a class record. [4]
