Direct answer
Your Turnitin ID is the credential that connects you to your institution's Turnitin environment — typically the class ID and enrollment key your instructor provides, which you enter once when you join the class. To use it, sign in through your university's Turnitin portal (or the link your instructor shares), enter the class ID and enrollment key when prompted, open the assignment, and submit your paper so Turnitin can generate your similarity and AI writing reports [1]. Visibility is governed by your institution: instructors can see the AI writing indicator on submissions, while what you can preview before submitting depends on the assignment settings your school has enabled [1].
What Is a Turnitin ID and What Is It Used For?
A "Turnitin ID" most commonly means the class ID and enrollment key that identify your seat in a Turnitin class. This pair is the doorway to every assignment your instructor has created, because without it you cannot reach the submission point where reports are generated. When you submit through that point, Turnitin processes your document and produces both a similarity score and an AI writing report [2].
The AI writing report is where your ID's real value shows up. It displays an overall percentage of qualifying text — prose in long-form writing — that the model predicts may have been generated by an AI tool, alongside a submission breakdown that highlights the specific sentences flagged in blue [2]. A score between 1% and 19% is shown as an asterisk (*%) rather than a number, while 0% and scores of 20% and above appear as exact percentages [2].
Importantly, the ID is not a magic key that reveals everything. Whether students can see their own AI percentage depends on how the assignment is configured, and Turnitin explicitly states the indicator is a signal for instructors to interpret rather than proof of academic misconduct [1][2]. Knowing this helps you use your ID with realistic expectations: it gets your paper processed, but your instructor controls what you can see.
In short, your Turnitin ID exists to route your work into your class's assignment workflow. Use it to enroll, submit, and generate the reports that inform your academic decisions [2].
Where Can I Find My Turnitin ID and How Do I Enter It Correctly?
Your class ID and enrollment key come from your instructor, not from Turnitin. They are usually published in your course page, syllabus, LMS announcements, or the welcome email for the course; if you cannot locate them, asking your instructor directly is the fastest fix [3].
To enter them, open Turnitin through your university's single sign-on portal and look for the option to enroll in a class. Paste or type the class ID and enrollment key exactly as given — they are case-sensitive, and a stray space or swapped digit is the most common reason an enrollment fails [3]. Once the pair is accepted, your account is linked to the class and its assignments appear on your dashboard.
If the system rejects the enrollment key, check for hidden spaces and verify you are using the current term's code, since instructors often rotate keys between terms. Turnitin's Students help center documents these exact scenarios, including why an enrollment key may not work and where to find the class ID in the first place [3].
One clarification: some students receive a different kind of identifier — a submission or paper ID generated after a document is uploaded. That ID tracks a specific submission rather than logging you in, so keep it alongside your class ID and enrollment key whenever you need to reference a particular report [3].
How Can I Get an Official Turnitin AI and Similarity Report on My Draft?
Inside institutional Turnitin, you generally cannot run a standalone check with your ID. As a student, you cannot self-check a paper without uploading it to an official assignment your instructor created, unless your institution has enabled Turnitin Draft Coach [4].
If Draft Coach is available, you can run your own similarity, citation, and grammar checks inside Google Docs or Microsoft Word before you ever touch an assignment. If it is not, your only pre-submission path is a draft submission to an assignment that allows resubmissions — the first three attempts usually generate a report immediately, while later attempts may require waiting up to 24 hours [4].
The catch is that many instructors disable resubmissions, which makes your first attempt final and leaves you with no preview at all. In that situation, Turnitin's guidance is to ask your instructor to set up a separate practice assignment, or to review your work before you commit your ID to the real submission [4].
That is why many students preview their paper with a checking service first, then use their Turnitin ID only for the final upload. Seeing the similarity matches and AI flags before you submit lets you fix problems while the draft is still yours to edit [4].
Your Turnitin ID is only half the equation — the other half is knowing what your report will show before that first submission becomes final. turnitin0 gives you that preview: upload your draft and receive real Turnitin AI writing and similarity reports, so you can review your score, flags, and match highlights before you ever use your ID on the official assignment.

FAQ
What is a Turnitin ID?
In most cases, a "Turnitin ID" refers to the class ID and enrollment key your instructor gives you to join a Turnitin class. It can also refer to the submission or paper ID assigned after you upload a document, which you use to locate that specific report [3].
Can I check my paper before submitting with my Turnitin ID?
Only if your institution has enabled Turnitin Draft Coach, or if your instructor's assignment allows resubmissions. If neither is true, your first submission is final, so it is safer to review your draft beforehand [4].
Why does my AI writing score show *%?
Turnitin displays any AI detection percentage between 1% and 19% as an asterisk (*%) instead of a number, because scores in that range are more prone to false positives. A clean result shows as 0%, while 20% and above appear as exact percentages [2].
Can students see the AI writing indicator in Turnitin?
Inside institutional Turnitin, only instructors and administrators see the AI writing indicator on submissions. Students typically see their own AI results only where the institution has enabled student-facing access [1].
Which files can I submit for AI detection?
Turnitin processes.docx,.pdf,.txt, and.rtf files for AI writing detection, provided the document contains at least 300 words of prose, is under 100 MB, and does not exceed 30,000 words [2].
