Direct answer
Every paper you submit to Turnitin is locked to a unique submission ID — a numeric identifier that appears on your digital receipt and inside the report PDF that Turnitin generates for your file. That ID is how instructors, institutions, and you can tell exactly which submission a similarity or AI writing report belongs to [1]. Because Turnitin processes every accepted file into both a similarity report and an AI writing report, the submission ID printed on your PDF is the key that connects your document to its official results [1].
Where Can I Find the Turnitin Submission ID on a PDF?
The submission ID is printed in the metadata block of official Turnitin report PDFs — both the similarity report and the AI writing report — usually near the paper title, author name, and submission date. When you download a report from an assignment inbox or from a checking service, that identifier travels with the PDF [2].
You will also see the same number in the email receipt Turnitin sends after a submission is processed. Matching the ID on your receipt to the ID inside the PDF is the fastest way to confirm that the PDF you hold belongs to your specific submission [2].
If the number is not visible on the PDF itself, open the assignment inbox and click the report icon for that submission; the details panel shows the submission ID associated with the file. On the AI writing report page, the submission details are displayed right alongside the percentage and the flagged sentences, so you can always trace a report back to its source submission [2].
What Does a Turnitin Submission ID Look Like and What Is It Used For?
A Turnitin submission ID is a long numeric string — typically more than a dozen digits — that Turnitin assigns the moment a file is accepted into the system. No two submissions share an ID, so it acts like a fingerprint for one specific version of a paper [3].
The ID's main job is tracking and retrieval: it lets instructors pull up the exact report for a submission, and it lets you reference a specific file when you contact support or discuss a result with your professor. Because receipts and submission records are tied to the ID, it is also the cleanest evidence that a genuine Turnitin check was actually run on your document [3].
Understanding how submissions are tracked matters before you press submit. Turnitin publishes clear guidance on when and how students can run checks on their own work, and keeping your own submission IDs and receipts organized makes your pre-submission checks easy to verify and easy to discuss later [3].
How Can I Preview My Turnitin AI Writing and Similarity Report Before Submitting?
You do not have to wait for an instructor to open an assignment before you see what Turnitin will say about your draft. Real Turnitin checking services let you upload your.docx,.pdf, or.txt file and receive the official AI writing report and similarity report — each carrying its own submission ID — before you submit anywhere [4].
Previewing the report early is exactly the proactive step that academic integrity guidance recommends: instead of being surprised by a high AI or similarity score after submission, you see the flags, the score, and the match highlights on your own draft first, and you can revise before anything is submitted [4].
Because Turnitin displays any AI score below 20% as an asterisk (*%), a pre-submission check also removes the guesswork about whether your writing will be flagged. Knowing your real numbers — and the submission ID attached to the report — means you walk into submission with evidence and control [4].
If you want to see the exact PDF a real Turnitin check produces — your submission ID, AI writing score, flagged sentences, and similarity summary — turnitin0 gives you official Turnitin AI and similarity reports on your own draft within minutes.

FAQ
What is a Turnitin submission ID?
A unique numeric identifier that Turnitin assigns to every accepted submission. It links your file to its similarity and AI writing reports and appears on the digital receipt and on the report PDF.
Where does the submission ID appear on a PDF?
In the metadata block near the top of the official similarity and AI writing report PDFs, alongside the title, author, and submission date. The same ID also appears in the email receipt you receive after submitting.
Can I verify a report with the submission ID?
Yes. Matching the ID on your receipt to the ID printed inside the PDF confirms that the report belongs to that specific submission, which is useful when discussing results with your professor.
Will my report PDF show an AI score?
Yes. Turnitin's AI writing report shows the percentage of AI-generated text in the document; any score below 20% is displayed as an asterisk (*%), and 0% is the only explicit low number shown.
How can I check my paper with Turnitin before submitting?
Use a real Turnitin checking service such as turnitin0, which delivers the official AI writing and similarity reports for your draft — with their submission IDs — before you submit to your institution.
