Direct answer
If you have ever submitted an assignment through Turnitin, you have likely seen a string of digits labelled Turnitin ID — also called the paper ID or submission ID — on your digital receipt or on the report header. That number is a unique identifier Turnitin assigns to every paper submitted to its system, and it is the key to locating the exact similarity and AI writing report for that submission [1]. Understanding what the Turnitin ID is and what the report attached to it contains helps you read your results accurately, and it tells you what to check before you ever click "Submit."
What Is a Turnitin ID and Where Can I Find It on My Report?
A Turnitin ID is a unique numeric identifier that Turnitin assigns to each individual submission the moment it enters the system. It is sometimes called the paper ID or submission ID, and no two submissions — even two drafts of the same essay — share the same number [2]. Because the ID is unique, it acts as the definitive reference for a specific version of your work.
You will find the Turnitin ID in three common places: on the digital receipt you receive after submitting, in the header of the similarity and AI writing report, and in the assignment inbox next to the paper title [2]. Instructors see the exact same identifier in their view, so when you quote your Turnitin ID in an email or support ticket, whoever reads it can pull up your precise submission and its reports.
The ID itself is a reference number rather than a score, so do not confuse it with the similarity percentage or the AI indicator. Knowing where to find it matters because the report header that displays the ID also displays the submission date, word count, and the report's score summary [2].
What Does a Turnitin ID Tell You About Your Submission and Report?
The Turnitin ID points to a specific submission, and the report tied to that ID carries the information that actually matters for your grade: the similarity index, the match breakdown by source, and the AI writing indicator [3]. When an instructor searches the assignment inbox, the ID is what lets them retrieve the exact submission and its full report rather than hunting through duplicate drafts.
The AI writing portion of the report tells you how much of the text was flagged as machine-generated, and it is important to read it correctly. Turnitin displays any AI score below 20% as an asterisk (%) instead of a single-digit number, and 0% is the only explicit low numeric outcome students typically see [3]. In other words, a % result is not a failure — it is Turnitin's way of saying the detected percentage is below its display threshold.
Because the ID is bound to one specific version, it also protects you in revision situations. If you received feedback on draft A and then improved it into draft B, the different Turnitin IDs make it clear which version each score belongs to, so there is no ambiguity about which report your instructor is evaluating [3].
Can I See My Turnitin AI and Similarity Report Before I Submit My Assignment?
In most university workflows, students cannot see their similarity or AI writing report before the submission deadline — and even after submitting, viewing is only possible if the instructor has enabled it [4]. Turnitin's own guidance for students makes clear that report access sits on the instructor's side, which is why so many students are surprised by their scores after an assignment is already locked in.
That is why many students use a trusted third-party Turnitin checking service to preview their reports in advance. These services deliver the same report format an instructor sees, including the Turnitin ID, the similarity breakdown, and the AI writing score, so you know exactly what is waiting on the other side [4].
Previewing before submission changes the stakes: you can fix unintentional similarity matches, revise flagged AI passages, and confirm your referencing is clean while you still have time to act. Waiting until after submission leaves you with a score you can no longer change [4].
If you want to see exactly what your instructor will see — your own Turnitin AI and similarity report, complete with the Turnitin ID, score breakdown, and every flagged section — turnitin0 delivers real Turnitin reports before you submit. Check your draft now and revise with confidence while you still have time.

FAQ
What exactly is a Turnitin ID?
A Turnitin ID — also called a paper ID or submission ID — is a unique numeric reference Turnitin assigns to every submitted paper. It identifies one specific version of your work and is how instructors and support teams locate the correct report [1].
Where can I find my Turnitin ID?
Check your digital receipt, the header of your similarity or AI writing report, or the assignment inbox beside your paper's title. All three locations show the same identifier [2].
Is the Turnitin ID the same as my similarity score?
No. The ID is a reference number for your submission, while the similarity score measures how much of your text matches other sources. The report header shows both side by side, but they are separate pieces of information [1].
Why does my AI score show *% instead of a number?
Turnitin displays any AI writing score below 20% as an asterisk (%) rather than a single-digit percentage. A % result simply means the detected percentage is below the display threshold; 0% is the only explicit low numeric score you will typically see [3].
Can I check my Turnitin report before submitting my assignment?
In most institutional workflows, no — students see the similarity and AI reports only after submission, and only if the instructor enables viewing [4]. Using a trusted third-party Turnitin checking service is the practical way to preview the exact report format before you submit [4].
