How can I tell if a citation is fake?

A fake citation usually fails one of three checks: its identifier (DOI, PMID, arXiv ID) doesn't resolve or points to a different paper; no database returns a matching title and author; or the journal, year or volume contradict the real record. Run all three and a fabricated reference almost always breaks on at least one.

How do I check if a citation is real?

Paste the single reference into CiteProve. It resolves any identifier, then searches Crossref, OpenAlex, PubMed and CourtListener for the title and authors. If a matching record is found, the citation is real; if nothing matches, it is flagged as not found; if a real source is found but fields differ, it is flagged as partial with a diff.

What does it mean if a citation can't be found?

It means the reference could not be located in the databases consulted — nothing more. CiteProve treats absence as a flag to check the source, never as proof the source is fake, because coverage has gaps: books without ISBNs, non-English work, and very recent papers can be real but unindexed.

Can I check a citation without an account?

Yes. Checking whether a citation is real is free, anonymous, and needs no sign-up. An email is only required if you want to save a shareable report.

Is this citation real?

Paste a single reference — or a whole list — and find out in seconds whether the source actually exists, whether the DOI points to the right paper, and whether any fields don't match the real record.

In short

To tell whether a citation is real, verify it against authoritative databases rather than judging it by how it looks. Resolve its identifier (DOI, PMID or arXiv ID), then search for the exact title and authors in Crossref, OpenAlex, PubMed and CourtListener. A real citation returns a matching record; a fabricated one fails to resolve and matches nothing; a mis-cited one matches a real source but with a wrong year, author or journal. CiteProve runs all of these checks at once and gives you a plain verdict — free, no account.

The three signs of a fake citation

The identifier breaks. The DOI or PMID doesn't resolve, or it resolves to a completely different paper than the one named.
Nothing matches. No database returns a work with that title and those authors — the reference simply isn't indexed anywhere.
The fields disagree. A real paper exists, but the year, journal, volume or author list in the citation contradicts the actual record.

Why “it looks right” isn't enough

Fabricated references — especially those from AI assistants — are designed to look correct. The formatting is perfect, the authors are real people in the right field, the DOI has the right shape. None of that proves the source exists. Only a lookup against the databases that actually register published work can confirm it.
