Direct answer
If you have ever submitted a draft to Turnitin—or to a service that runs a Turnitin check—you may have noticed a numeric reference tied to the report. That reference is often called a Turnitin check ID, and it is the key to locating your similarity and AI writing reports later [1]. Understanding what it is, where it appears, and how to use it saves you from hunting through email receipts or guessing which report is yours. This guide explains the check ID from the student's point of view and shows how to get an accurate report before you submit.
What Is a Turnitin Check ID and Where Can You Find It?
A Turnitin check ID is the identifier Turnitin assigns to each submitted document so the similarity report and the AI writing report can be retrieved from the same detection record. In the official help center, Turnitin describes how every submission is logged with its own record, and the AI writing report is generated for that record alongside the similarity percentage [2]. In practical terms, the check ID is the "address" of your report: it lets you, or the instructor, pull up the exact version of the file that was analyzed [2].
Where you find it depends on where the check was run. In a university course, the submission receipt and the report page display the paper ID or submission reference next to the file name. In a third-party check service, the ID is typically shown on your order confirmation or in your account's report history.
Either way, the ID is not a score and it is not an indicator of plagiarism. It is metadata that ties your file, your similarity match highlights, and your AI detection percentage together in one record. Keeping it handy is useful if you need to reopen a report or verify that a check was performed on the correct draft.
How Do You Use a Turnitin Check ID to Retrieve Your Similarity and AI Reports?
Once you have the ID, retrieving the report is straightforward because Turnitin stores the similarity report and the AI report under the same submission record. The help center explains that opening the report view shows your overall similarity percentage, the sources matched, and the highlighted passages from that specific submission [3]. If the same document is checked more than once, the ID tells you which version corresponds to which result, so you are never confused about whether you are looking at the latest check [3].
For students using an external checking service, the same principle applies: the check ID links your uploaded file to the generated reports in your history. You can revisit the results days later without re-uploading, and you can compare multiple drafts side by side.
A practical tip is to record the ID with the date and the file version name in your notes. That way, when you revise and re-check, you can confirm that the score you are discussing belongs to the right draft, which is exactly what instructors expect when you ask about your AI writing result.
How Can You Get a Real Turnitin AI and Similarity Report Before You Submit?
The best time to see your Turnitin check ID in action is before your assignment reaches your professor. Turnitin's own guidance encourages authors to review detection results during drafting so that citation and paraphrasing issues are fixed early, rather than discovered after submission [4]. A pre-submission check with the official-style report lets you see the exact similarity percentage, the flagged sources, and the AI writing indicator that an instructor would see [4].
That is why running a real Turnitin check on your final draft matters. The report should come from the same detection engine used in your institution, with the same score bands and the same low-score display rules, so there are no surprises on submission day.
When you run the check, keep the check ID that comes with it. It is your proof that the report belongs to your file, and it makes discussing the result with your tutor or your own revision process far simpler.
If you want the same real Turnitin AI and similarity report your professor would see—attached to your own check ID, with the full score breakdown and match highlights—turnitin0 lets you run the check before you submit. Your files are not archived and are never sent to any third-party database, so your draft stays private while you get an accurate preview of how it will be scored.

FAQ
What is a Turnitin check ID?
A Turnitin check ID is the reference number attached to a specific submission record. It links your uploaded file to its similarity report and AI writing report so both can be retrieved from the same record [1].
Where can I find my Turnitin check ID?
In a university course, look at the submission receipt or the report page next to your file name. In a third-party checking service, it appears on your order confirmation or in your report history [2].
Can I reopen my AI report later using the check ID?
Yes. Because the similarity and AI reports are stored under the same submission record, the ID lets you reopen the correct version of your results without re-uploading the file [3].
Does the check ID affect how my AI score is displayed?
No. The ID is only an identifier; the score display rules are set by the detection engine, so sub-20% results still appear as an asterisk rather than a low single-digit number [1].
Should I run a Turnitin check before submitting?
Turnitin's own guidance recommends reviewing detection results during drafting so issues are caught before the assignment is submitted [4]. A pre-submission check with the official-style report gives you an accurate preview of what your instructor will see.
