Direct answer
A "Turn it in ID" is not a single, official account number. Turnitin does not issue students a personal ID the way a university issues a student number. What people usually mean is one of three identifiers attached to coursework: the submission ID for a specific paper, the class ID your instructor uses to set up a Turnitin course, or the assignment/paper ID that ties a file to a dropbox. All three are created by the institution's setup, not by the student, and all three are visible inside the assignment inbox where reports are opened [1]. If you were told to "find your Turnitin ID," the useful next step is to work out which of the three is meant, because each lives in a different place and none of them can be looked up on a public page.
What does a Turnitin ID actually refer to — submission ID, paper ID, or class ID?
The three identifiers serve different jobs, and mixing them up is the most common source of confusion. A class ID identifies a Turnitin course shell — it is the code an instructor shares when students must self-enroll outside an LMS. A paper or submission ID identifies one uploaded file inside one assignment. An assignment ID identifies the dropbox itself. None of these is a student identity; they are records of coursework, which is why the same student can hold dozens of them across a degree [2].
Turnitin's help documentation is consistent on where these records surface: a student opens the assignment in their course, then clicks the similarity percentage or report icon next to their own submission to see the report attached to that record [2]. The report header carries the paper's own metadata — title, author name, submission date — which is how you confirm which submission a given report belongs to [1]. That metadata, not a memorable code, is what most students actually use to identify their paper.
The practical implication is that "my Turnitin ID" is rarely a single value you can memorise. If an instructor asks for it, they almost always mean the submission record for a specific assignment, and they can already see it on their side of the same class [2]. If a support agent asks for it, they usually want the class ID and assignment name instead, because those are what locate the dropbox in the institutional account [1].
One caution worth stating plainly: because these identifiers belong to an institution's class structure, they are not transferable. A class ID from last semester will not open this semester's dropbox, and a submission ID from one university's Turnitin integration means nothing in another system [1][2]. Treat any ID you are given as scoped to one course and one assignment.
Where do students find their Turnitin submission ID or class ID?
Start with your course, not with Turnitin. In an LMS-integrated course — Canvas, Moodle, Blackboard, Brightspace — you will usually never see a class ID at all, because enrollment is handled by the integration and the class is created behind the scenes [3]. What you will see is the assignment, your submission, and the report link attached to it [2]. That is the normal, expected experience for most university students, and the absence of a visible class ID is not a problem.
Class IDs and enrollment keys are issued by the instructor or the LMS administrator, never by Turnitin to students directly [3]. If your course requires self-enrollment in a standalone Turnitin account, the instructor posts the class ID and enrollment key in the syllabus, the course announcements, or an email — that message is your source of truth, and it should be treated as confidential to your cohort [3]. If you cannot find it, the correct move is to ask the instructor rather than to search for a lookup tool, because no public lookup exists.
Report visibility is also controlled by settings the instructor chooses for each assignment [3]. This explains the most common "I can't find my ID or report" scenario: the submission exists, but student access to reports is switched off, or the file has not finished processing yet [2]. Before assuming something is broken, check whether classmates can see their reports for the same assignment — if nobody can, it is a course setting, not a missing ID [3].
For AI-related results specifically, Turnitin reports a percentage of qualifying prose, and low-confidence results display as an asterisk rather than a number [3]. That asterisk is a display convention, not a missing identifier, and it is worth knowing before you interpret a report you have just located.
Can you get a Turnitin report without an institutional class ID?
Yes — but the report has to come from a system that actually generated it, and the identifier from one system will not work in another. Turnitin's own guidance notes that report layout and access differ between an institutional integration and a standalone account, so a class ID from your university cannot be pasted into a different product to retrieve your paper [4]. Any service claiming to "look up" your report from an ID alone is describing something Turnitin does not offer.
It also helps to know what the report is measuring before you go looking for one. A similarity score is the percentage of a paper's text that matches other sources; it is not a verdict on intent, originality, or quality [4]. The report highlights the specific matched passages so you can see exactly what triggered a match and revise it deliberately [4]. Reading the score without reading the highlighted text is where most panic about "flagged" work begins.
Two further details change the number you see. Instructors can exclude quotations, the bibliography, and small matches from the calculation, so the figure recorded on their side may differ from the figure you first saw [4]. And because every submission is tied to one assignment record, a report retrieved outside that record cannot be verified against the version your instructor graded [1][4].
The practical route for a student who wants certainty before submitting is to check the draft against the same report format the institution uses, on their own file, without needing a class ID at all. That is a preview, not an enrollment — it does not place you in a course shell, and it does not create a submission record in your instructor's account [1][4].
If the identifier hunt has left you unsure what your own draft would actually score, turnitin0 closes that gap: you upload your file and get back the two PDFs your instructor's system would produce — the AI writing report and the similarity report — so you can see the score, the flagged passages, and the match highlights before anything reaches your course. No class ID, no enrollment key, no course shell: just your draft and the report it would generate.

FAQ
Is a Turnitin ID the same as my student ID?
No. Your student ID is issued by your university; a Turnitin class ID, assignment ID, or submission ID is created inside a course shell and belongs to that coursework record, not to you as a person [1][2].
Why can't I see a class ID anywhere in my course?
Most LMS-integrated courses never expose one, because enrollment is handled by the integration rather than by self-enrollment [3]. If your instructor requires self-enrollment, they will post the class ID and enrollment key directly [3].
Does a submission ID prove my paper was checked?
It identifies the submission record, not the outcome. The report attached to that record is what shows the similarity and AI results, and access to it depends on the instructor's assignment settings [2][3].
Can I reuse an old Turnitin ID for a new assignment?
No. Identifiers are scoped to one class and one assignment, so a code from a previous semester or a different institution will not resolve in a new course [1][4].
What does an asterisk instead of an AI percentage mean?
It is Turnitin's display for a low-confidence AI result rather than a missing identifier, so the report exists — the detection signal simply fell below the confidence threshold for a numeric value [3].
