Direct answer
When a Turnitin report shows a submission ID but no percentage, the check was received and processed — the ID is the proof of that — but the numeric score is not displayed for one of two reasons: the report is still rendering, or the score falls into a display bucket where Turnitin shows an asterisk () instead of a number [1]. In the AI writing report, any score below 20% is shown as % rather than a single-digit figure, so "no percentage" is often just Turnitin's low-score display, not a broken report [1]. If you need a clear, numeric preview before submitting, run your draft through a real Turnitin AI and similarity check.
Why Does a Turnitin Report Show a Submission ID But No Percentage?
A submission ID appearing without a percentage usually means the report has been created but the numeric result has not been rendered into the view yet, or the result is being presented through a non-numeric display rule [2]. Turnitin's AI writing report is generated after a paper is processed, and the submission ID confirms that processing happened even when a score is not immediately visible [2].
The most common reason students see an ID without a percentage is Turnitin's AI writing indicator display logic. When the AI score falls below 20%, Turnitin does not show a single-digit number such as 3% or 12%; it shows an asterisk (*) instead [2]. That means a fully processed, valid report can contain zero visible numbers — which is exactly why a student sees "ID but no percentage" and assumes something went wrong.
The same logic applies to the similarity side in different ways. A similarity percentage requires matching sources to be found and calculated, so an ID can appear before the percentage finishes computing [2]. In short: an ID with no percentage is normally a display or timing issue, not a failed or missing check.
What Does the Asterisk (*) Instead of a Numeric Percentage Mean in the Turnitin AI Report?
In the Turnitin AI writing report, the asterisk () is a deliberate display bucket, not an error code [3]. Any AI score below 20% is shown as %, and the only explicit low numeric outcome a student typically sees is 0%; otherwise sub-20% results appear as the asterisk bucket [3]. This is why a report can show an ID and an asterisk but no numeric percentage.
Practically, an asterisk (*) is a positive signal for the student: it means the AI writing indicator did not find enough AI-generated text to assign a visible number [3]. It does not mean the report failed, and it does not mean the paper is flagged — it means the AI-writing share is at or near the low end of the scale.
The same bucket logic matters when you are reading any percentage you receive later. If an instructor or a checking service later gives you a numeric value, you should check whether it is an explicit number like 25% or a bucket symbol, because Turnitin treats sub-20% AI results as *% rather than as single-digit numbers [3]. Knowing this display rule stops you from misreading a clean result as a missing or broken report.
How Can I Check My Real Turnitin AI and Similarity Percentage Before Submitting?
Through the standard Turnitin student view, you generally cannot see a similarity or AI percentage before the assignment is submitted and the instructor makes results available [4]. That means most students have no way to preview their real percentages in advance — which is why an ID-only or asterisk result on a draft check can feel confusing [4].
To see your real Turnitin AI and similarity percentages before the final submit, you can run your draft through a Turnitin checking service that generates the same reports instructors see. On turnitin0, you upload your .docx, .pdf, or .txt file and receive both a similarity/plagiarism report and an AI detection report that match what professors see in their academic systems — including how the * bucket is displayed.
The check is processed quickly, with reports delivered in about 5–10 minutes in 99% of cases (30 minutes guaranteed in rare cases), and it is pay-per-use with no subscription [4]. Because the reports mirror the institutional view, you get an accurate read on whether your percentage is visible, in the * bucket, or a numeric value — so you can decide whether to adjust, humanize, or submit with confidence.
If your current Turnitin report only shows an ID or an asterisk instead of a clear percentage, the fastest way to stop guessing is to get the real report before you submit. turnitin0 gives you an actual Turnitin AI writing report and similarity report — the same view your instructor's system shows — so you can finally see exactly what your draft scores. Upload your file and preview your real percentage in minutes, with pay-per-use pricing and no subscription.

FAQ
Does "no percentage" mean my Turnitin AI score is 0%?
Not necessarily. If the report shows an asterisk (*) or no number, it means the AI score is below 20% and Turnitin hides single-digit values in that bucket — the only explicit low number shown is 0% [1][3]. Either way, it is a low-AI result, not a flag.
Why does my similarity report show an ID but no similarity percentage?
The similarity percentage is calculated after matching sources are found, so an ID can appear before the percentage finishes rendering [2]. If it stays empty, give the report time to generate or run a fresh check.
Is an asterisk (*) in the AI report good or bad?
It is good. An asterisk means Turnitin did not detect enough AI-written text to display a numeric score, so your draft sits in the low, sub-20% AI range [3].
Will my paper be stored or shared if I use a Turnitin checking service?
On turnitin0, submitted papers are not archived and are never sent to any third-party database, so your draft stays private while you preview your real AI and similarity reports [4].
How long does a real Turnitin check take?
In 99% of cases, reports are delivered within 5–10 minutes; in rare cases delivery is guaranteed within 30 minutes, and results are valid for 100 days per check [4].
