Direct answer
A Turnitin submission ID is a unique numeric reference that Turnitin assigns to a paper the moment it is submitted to an assignment inbox. You will see it on the submission receipt and again on the similarity and AI writing reports, where it links the file in your account to that exact submission [1]. Knowing what this number is — and where to find it — makes it easy to confirm your work was received and to reference it if you ever need to verify a submission with your instructor.
What Is a Turnitin Submission ID and Why Does It Matter?
A submission ID is the unique identifier Turnitin generates for each paper submitted to an assignment, typically a multi-digit number. It functions like a receipt number: every time you upload a file, Turnitin logs that file under its own ID so the system — and your instructor — can tell exactly which version was submitted and when. This is why the ID appears not only in your confirmation email but also inside the similarity and AI writing reports attached to that submission [2].
The ID matters because it connects your submitted file to everything Turnitin generated for it, including your similarity report and AI writing detection results [2]. If you submit multiple drafts, each one receives a new ID, so the number tells you — and your instructor — which version produced which report. When you open the AI writing report for a paper, the submission ID shown on the page confirms you are looking at the right draft rather than an older upload.
Because the ID is issued at the exact moment of submission, it also works as evidence that your assignment was recorded in the system. Instructors and support teams can use it to look up your submission if there is ever a question about whether it arrived. Keeping the number, for example from the receipt email, is the simplest way to resolve a "did my paper actually submit?" worry.
Where Can Students Find Their Turnitin Submission ID Number?
The easiest place to find your submission ID is the confirmation you receive right after you upload your paper. Turnitin displays the submission ID on the digital receipt on the submission page, and many institutions also email the same number to you as soon as the submission is recorded [3]. Checking this email first saves time, since it contains the ID alongside your class and assignment name.
You can also see the ID inside the report itself. When you open your similarity report or AI writing report, the submission ID is displayed with the paper details, next to the file name, class, and assignment name [3]. This is the same number your instructor sees in their copy of the report, so you can reference it directly in any conversation about your submission.
Finally, most assignment pages in Turnitin or in your LMS, such as Canvas or Blackboard, list your most recent submission and its ID under the assignment details or submissions view. If you submitted more than once, check that the ID matches the receipt for the version you intend to keep, because each upload carries its own number.
Why Should Students Check Their Turnitin AI and Similarity Report Before Submitting?
Your submission ID exists because every paper is checked the moment it lands in the inbox — instructors see a similarity score and, where enabled, an AI writing score for that exact submission [4]. Checking your own Turnitin report before you press submit shows you the same numbers your instructor will see, so there are no surprises after the deadline.
A pre-submission check lets you spot accidental similarity matches, such as a missing citation or an over-quoted block, and any AI writing flag while you can still edit. Universities increasingly discuss AI writing detection openly with students, and knowing your report's outcome before submission lets you respond to questions about your writing process honestly and confidently [4].
In practical terms, the safest workflow is: write → run your draft through a real Turnitin check → review the similarity and AI reports → fix what needs fixing → submit → keep the new submission ID from your receipt. That final ID then points to a clean, verified submission you can stand behind.
None of this has to happen in the dark. Before you submit — and before your submission ID is ever generated — you can preview exactly what your instructor will see. turnitin0 gives you real Turnitin AI and similarity reports on your own draft, so the version you finally submit is the version you have already verified.

FAQ
1. What is a Turnitin submission ID number?
It is a unique numeric identifier that Turnitin assigns to every paper at the moment of submission. It functions like a receipt number that ties your file to its similarity and AI writing reports [1].
2. Where can I find my Turnitin submission ID?
Check the digital receipt on the submission page, the confirmation email from your institution, or the paper details inside your similarity and AI writing reports [3]. Most LMS assignment pages also list it.
3. Does every draft I submit get a new submission ID?
Yes. Each upload is a separate submission and receives its own ID, so the number tells you which version produced which reports [2].
4. Is the submission ID the same as the paper ID?
The submission ID identifies the specific submission event in the assignment, and it is the reference shown with your reports and receipt. Use it whenever you need to point your instructor or support team to the exact version you submitted [1].
5. Do I need my submission ID to check my report?
No. You can open your similarity and AI writing reports directly from the assignment page. Still, keeping the submission ID from your receipt is the fastest way to confirm which draft your report belongs to [2][4].
