An ORCID peer-review entry records a review contribution added by a trusted organization, not a manual field the researcher types. It says nothing conclusive about authorship of the reviewed paper, and anonymized entries may hide the reviewed work or report entirely. If the entry is absent, private, mismatched or ambiguous, record that exact limit and stop there.

What kind of record a review entry is
On ORCID, individual peer-review entries can only be added by trusted organizations through the Member API with the holder's permission; the holder cannot add them manually. That makes a review assertion different in mechanism from a hand-entered item: an organization made it, not the researcher alone. It is still a claim about one role in one workflow, and its presence does not extend to any other claim about the person. [ORCID: peer review contributions]
Reviewer, organizer and reviewed work are three different things
A review contribution is not authorship of the reviewed work. Keep three objects apart: the reviewer (the person the entry concerns), the organizing body that added the entry, and the reviewed work itself. Evidence about one tells you nothing settled about the others. A review entry is evidence of a reviewing role attributed to the record; it is not evidence that the person wrote, co-wrote or approved the paper, nor that an employer endorsed anything.

Visibility decides whether you can see it at all
The holder must make review activity public for it to appear on the public record. If you cannot find an entry, the ordinary explanation set is: not made public, added by an organization you have not located, or simply not present. Absence is not a finding that the review did not happen, and presence of a record does not prove any particular unpublished report exists. Read what is visible, then name the limit rather than filling it with a guess. [ORCID: peer review contributions]
Anonymized and grouped entries: read the gap precisely
Entries can be anonymized and grouped by shared identifiers. An anonymized entry may therefore withhold the reviewed subject or the report while still asserting that a review contribution exists. This is a deliberate scope boundary, not a puzzle to solve. Do not try to infer the hidden review subject, the manuscript, the journal decision or the identity behind a grouped identifier. The correct output is: a review is recorded, the subject is not public, and further inference stops here. [ORCID: peer review contributions]
A short evidence table for your own notes
Use a plain table to keep observations, their limits and your decision separate. The example below is hypothetical and is a reader aid, not a description of any platform control.
| observation | limit | next step |
|---|---|---|
| A public profile shows a peer-review entry | It records a review role, not authorship of the paper | Describe the person as a reviewer per that entry only |
| The entry is anonymized or grouped | Reviewed subject or report may remain unavailable | Record the review claim; make no claim about the paper or venue |
| No public review entry appears | Activity may be non-public or not present | State 'not publicly visible' and stop |
When the source is absent, private or ambiguous
If the source is absent, private, mismatched or ambiguous, record that precise limit and stop the unsupported inference; do not seek private access or bypass identification. Do not treat a public status, a badge or a privacy setting as proof of identity, intent or quality. Separate what you observed, what the mechanism allows you to conclude, and what you actually need to decide. For most purposes the decision is simply: describe the review contribution as recorded and leave authorship, employers and hidden review subjects unstated.
A couple more questions
Does an ORCID peer-review entry mean the person authored the paper?
No. The entry is a review contribution, explicitly distinct from authorship of the reviewed work. It also cannot be added by the holder manually; a trusted organization adds it with permission. Treat authorship only from the paper's own record.
Why can't I find a review entry I expected?
Review activity must be made public by the holder to appear on the public record, and entries are added by organizations rather than the individual. A missing entry may be non-public or not present. Record 'not publicly visible' and stop rather than seeking private records.
Can I work out which paper or report was reviewed from an anonymized entry?
No reliable path is described here. Entries can be anonymized and grouped by shared identifiers, so the reviewed subject or report may stay unavailable by design. Do not attempt to infer or identify hidden review subjects; state the visible review claim and the gap.
