What it is
FaceCheck ID is a paid, credit-based facial recognition search engine that takes an uploaded photo and returns visually similar faces found across the public web, functioning as a competitor to PimEyes in the same reverse-face-search category.
FaceCheck ID is a facial recognition search engine that accepts an uploaded photo and returns matches from across the public web, ranked by visual similarity, using a credit-based payment system. It positions itself partly around missing-persons use cases, and offers an opt-out process for people who want their own face excluded from results.
Like PimEyes, it sits in a legally and ethically contested category: facial recognition search on public photos is legal in some jurisdictions and heavily restricted in others, and the same third-party analysis that has scrutinised PimEyes has raised similar concerns about FaceCheck ID enabling stalking and harassment when used without safeguards.

How do you use FaceCheck ID responsibly?
Six steps that front-load verification and legal caution given the tool's contested legal status.
The following resources are used across the steps below.
FaceCheck ID: Paid, credit-based, crypto payments accepted. The facial recognition search engine covered in this guide.
Google Images: Free. A non-biometric reverse image search to try first, since it carries none of the same legal exposure.
| Before you begin Stop at the login. FaceCheck ID requires an account and purchased credits to search; no login is required to upload a photo for a search, only to pay for and view full results. Nothing in this workflow logs into a target's account. Legal considerations. Facial recognition search on scraped public images is restricted or banned outright in a number of jurisdictions, and its legality depends heavily on where you are and where the subject is. Third-party analysis has criticised FaceCheck ID, in the same terms applied to PimEyes, for enabling stalking and harassment when used without safeguards. Confirm the legal status of facial recognition search in your jurisdiction before using it, never search a minor's face, and treat any result as a lead requiring independent corroboration, not a confirmed identity. |
Run the photo through Google Images or TinEye before paying for a facial recognition search, since a simpler tool sometimes surfaces the same or a better result.
Facial recognition search is restricted or banned in a number of jurisdictions. Confirm your own legal position, and the subject's likely jurisdiction, before proceeding.
Use a photo showing the subject's face clearly, without obstruction, for the most reliable results.
Treat every returned match as a candidate requiring independent verification, since visual similarity is not the same as confirmed identity.
Cross-check a strong candidate against other identifying information, such as a name, location or other account activity, before treating the match as confirmed.
Do not run a search on a photo of a minor under any circumstances, regardless of the investigative justification.

What are the pitfalls of using FaceCheck ID?
Visual similarity is not identity, and the tool's legal status varies sharply by jurisdiction.
A visual-similarity match mistaken for confirmed identity: the tool ranks by facial similarity, which can surface a genuinely different person who simply looks alike. Verifying check: corroborate any match against independent identifying evidence before treating it as confirmed.
Legal status assumed uniform across jurisdictions: facial recognition search is legal in some places and restricted or banned in others. Verifying check: confirm the legal status specific to your jurisdiction and the subject's before running a search, not after.
An opt-out request mistaken for full data removal: requesting your own removal from the index addresses future searches, not necessarily results already generated or cached elsewhere. Verifying check: treat an opt-out as reducing, not eliminating, ongoing exposure.
Chain of custody: facial recognition results are biometric-adjacent data and warrant the same caution as any other sensitive personal data.
Record the source photo used and the date the search was run.
Log every candidate match reviewed, including ones later ruled out, and why.
Document the independent corroboration used to confirm any match before it is relied on.
Note the jurisdiction assessment made before running the search.
