Direct answer
A Turnitin ID (also called a paper ID) is a unique numeric identifier that Turnitin assigns to every paper the moment it is submitted. It appears on the Similarity Report alongside the title, author, and submission date, so any specific paper can be identified and retrieved quickly [1]. The ID is not a score — it says nothing about similarity or AI content — but it is the fastest way for instructors and support teams to pull up the exact submission you are asking about [1].
What Does the Turnitin ID on a Similarity Report Mean?
The Turnitin ID is a system-generated reference number, not something you choose or change. Every submission — whether it goes through an assignment inbox in your university's LMS or directly into Turnitin — receives its own unique ID the moment it lands in the system, and no two papers share the same one [2]. When you open the Similarity Report, the ID appears in the submission details area together with the paper title, author, and submission timestamp.
Because the ID is unique, it acts as the paper's fingerprint inside Turnitin's database [2]. If you email your instructor or Turnitin support about a specific report, quoting the ID lets them open that exact paper in seconds instead of searching by name or date. Think of it like a booking reference: the report itself carries the meaning, while the ID is the key that unlocks it.
A common confusion is mixing the Turnitin ID with the similarity index or the AI writing score [2]. The similarity percentage measures how much of the paper matches other sources, and the AI score estimates AI-generated content; the ID does neither. It simply labels the submission, so it is not something that can be improved or lowered — it is just how the system refers to your paper.
How Is a Turnitin ID Used to Find or Reference a Submitted Paper?
Instructors use the Turnitin ID every day to locate one specific submission among dozens or hundreds in an inbox. Because each paper ID is unique, opening a submission by its ID takes you straight to the correct report — the same report a student sees, with the same similarity index, source matches, and submission metadata [3]. The ID is also the standard reference when a paper is discussed across systems.
If a paper is submitted more than once, Turnitin records a separate ID for each submission, so quoting the exact ID tells everyone which version is being discussed [3]. This is why university guides and support pages consistently ask students to include their Turnitin ID when reporting a technical problem. Students rarely need the ID day-to-day, but knowing where to find it matters.
On the Similarity Report it is listed with the submission details, and in Feedback Studio it is visible in the assignment inbox next to the paper title [3]. Noting it down before you contact anyone about your submission saves a full round of back-and-forth, because the person on the other end can verify the paper in seconds rather than guessing which file you mean.
How Can Students Check Turnitin AI and Similarity Reports Before Submitting?
The best time to understand every field on your report — including the Turnitin ID — is before the paper is ever submitted to your university. Many students run a pre-submission Turnitin check so they can see the same similarity and AI writing reports their instructor will receive, instead of discovering an unexpected result after the deadline [4].
A pre-submission check works exactly like an institutional submission: the paper receives its own report with the similarity index, source matches, AI writing percentage, and the same kind of submission metadata you would see in class [4]. Because Turnitin displays any AI score below 20% as *%, the only clear low result students can confirm is a 0% reading.
Checking early changes the conversation from "what does this ID mean?" to "what do my scores say?" — the ID simply confirms your paper is in the system, while the score tells you whether to revise or polish before the real hand-in [4]. Run the check, read every field, and submit with the full picture instead of a guess.
Now that you know what a Turnitin ID is — and that the real signal in any report is the similarity index and the AI writing score — the smartest move is to preview your own report before it reaches your instructor. Turnitin0 delivers real Turnitin AI and similarity reports on demand, so every field on your draft stops being a mystery: you see the exact report cover, score, flags, and similarity summary, exactly as your professor would.

FAQ
Q: Is the Turnitin ID the same as the similarity score?
No. The Turnitin ID is a unique reference number that identifies the submission, while the similarity percentage measures how much of the paper matches other sources [1]. The two values appear on the same report but mean completely different things.
Q: Where can I find my Turnitin ID?
Look in the submission details area of the Similarity Report, next to the paper title, author, and submission date [2]. In Feedback Studio, it is also shown in the assignment inbox beside the paper title [1].
Q: Can two papers have the same Turnitin ID?
No. Every submission receives its own unique ID, and a resubmission is recorded as a new submission with a new ID [2]. Quoting the exact ID is the only way to make sure everyone is looking at the same version of the paper [3].
Q: Does the Turnitin ID affect my AI score?
No. The ID is only an identifier and has no influence on similarity or AI detection results [2]. If you want a lower AI reading, the text itself — not the ID — is what needs to change [4].
Q: Can I see my paper's report and ID before submitting to my university?
Yes. Pre-submission services such as turnitin0 generate a real Turnitin AI and similarity report for your draft, showing the same fields — including the report metadata — that your instructor would see after submission [4].
