Direct answer
Turnitin does not run a public lookup page where you can paste a paper ID and instantly pull up a percentage — the score is attached to your submission inside your instructor's Turnitin assignment, and only people with access to that class can open the report [1]. If you hold a paper ID from a university submission or from a checking service, the real question is what that ID lets you see and where you should enter it. This guide explains how Turnitin links paper IDs to similarity and AI percentages, what those percentages actually mean, and how to preview both scores before you submit [1].
Can I Check My Turnitin Similarity Percentage Using a Paper ID After Submission?
A paper ID is generated the moment a submission is processed, and Turnitin attaches the similarity report to that paper inside the assignment inbox. Students and instructors with access to the class open the report directly from the submission row, where the percentage appears on the report cover next to the paper ID [2]. The ID itself is a reference for locating the exact submission — it does not unlock the report outside the class where the paper was submitted [2].
If your ID came from a third-party checking service, that is a separate system: the ID is that service's report reference, not a Turnitin credential. With a genuine Turnitin report, you can confirm the similarity and AI percentages on the cover page, and the same numbers are what your instructor sees in their inbox [2]. In most university setups, students can view these percentages in the assignment after the instructor releases reports or after the due date.
What you cannot do is find a universal "enter ID, see percentage" portal on turnitin.com — no such public tool exists. Practically, checking your percentage "with an ID" means opening the report in the system that generated it, or using a service that delivers the institutional-style report directly to you. Keep your paper ID handy because it is also what support teams use to verify which submission and report belong to you [2].
What Exactly Does the Turnitin Similarity Percentage Measure in a Report?
The similarity percentage is the share of your paper that matches text found in Turnitin's databases — web content, published works, and previously submitted student papers — after any exclusions you or your instructor applied. It is a matching indicator, not a judgment that plagiarism occurred; the report simply shows where the matches appear and how much of the paper they cover [3]. Instructors interpret that percentage in context, which is why the same score can mean different things in different assignments.
In the AI writing report, the presentation follows strict formatting rules: any score below 20% is displayed as an asterisk bucket (%), rather than as a single-digit number such as 3% or 12% [3]. The only explicit low numeric outcome students typically see is 0%; everything else under 20% appears as the asterisk bucket. This formatting is identical to what instructors see in their institutional reports, so a preview that shows % matches the official display [3].
The final percentage also depends on exclusions such as quotes and bibliographies, and it is recalculated if the instructor changes settings. Because the calculation is deterministic, checking your draft before submission shows the same percentage Turnitin would display on the official report [3]. That predictability is exactly why pre-submission checks are useful: the number you see early is the number your instructor will see.
How Can I Preview My Turnitin AI and Similarity Percentage Before I Submit?
Turnitin supports draft checking before the final submission so students can see both the similarity and AI percentages while there is still time to revise. These previews surface the same report format — cover, score, flags, and similarity summary — that appears on the official report after submission [4]. Educators themselves encourage this kind of early check so students can understand the score before it affects a grade.
The same logic applies when you use a service like turnitin0: you upload your file and receive a real Turnitin AI and similarity report that mirrors what university instructors see in their systems, including the score display rules and flag summaries [4]. This lets you compare the percentage against your own expectations and decide whether to revise or rewrite before submitting. Most users receive these reports within minutes, which means you are never guessing about your percentage at the last minute [4].
The practical workflow is simple: keep your paper ID for reference, upload your draft in.docx,.pdf, or.txt format, and review the delivered report before your deadline. If the AI percentage shows *% or 0%, you know the text is reading as human-written; if a flag appears, you still have time to address it. Previewing first removes the uncertainty that comes from submitting blind and hoping for the best.
With your paper ID and a real Turnitin report, your percentage is never a mystery — the challenge is getting a report you can actually read before your deadline. turnitin0 delivers the same institutional-style Turnitin AI and similarity reports that students see in their university systems, so you can confirm your percentage with a genuine report cover, score, flags, and similarity summary before you submit.

FAQ
Can I check my Turnitin percentage just by entering my paper ID on turnitin.com?
No. Turnitin does not offer a public lookup portal for paper IDs; the percentage is viewable only inside the class where the submission was made, or through the service that generated the report for you [1].
How long is a Turnitin report available after submission?
Reports remain attached to the submission in the assignment inbox and stay available as long as the instructor keeps the assignment open. If you need your own copy, save or download the report while you have access [2].
Why does my Turnitin AI score show *% instead of a number?
Turnitin displays any AI score below 20% as an asterisk bucket (*%) rather than as a single-digit percentage; the only explicit low numeric outcome students typically see is 0% [1][3].
Are the similarity percentage and AI percentage in the same report?
No. The similarity report measures text matching against Turnitin's databases, while the AI writing report shows how much of the paper may be machine-generated. Both are delivered together as separate reports in the same submission [2][3].
Is a paper ID the same as a submission ID?
Yes — Turnitin generates a unique paper ID for each submission, and it serves as the reference for locating that submission and its reports. Keep it when contacting support or verifying which report is yours [4].
