How a scan works
- The item you enter is matched against the registry and the public feeds below.
- Live lookups add context: domain age and registrar, sanctions screening, blockchain activity.
- Pattern checks flag known scam signals such as look-alike domains and recovery-scam wording.
- Borderline results get an AI second opinion trained on confirmed outcomes.
- You get a verdict with the reasons behind it, and listed entities can appeal.

Frequently asked questions
What is GACS?
GACS (Global Anti-Crime & Safety) at gacs.app is an independent anti-fraud service that lets anyone check websites, links, phone numbers, emails, crypto wallets and social accounts against a public scam registry, for free.
Where does GACS get its scam data?
From public threat feeds and open-source lists — ScamSniffer, OpenPhish, URLhaus, PhishTank, Spam404 and the UK FCA warning list — plus moderated visitor reports. Each registry entry keeps its source.
How does a GACS scan reach a verdict?
It combines registry matches, domain age and registration data, sanctions screening, blockchain lookups and pattern checks, then explains the result. Borderline results get an AI second opinion trained on confirmed outcomes.
Does GACS recover lost money?
No. GACS checks and warns. It never charges victims to recover funds, and it points people to official reporting channels such as the FTC, IC3 and Report Fraud.
Is GACS free?
Scans (5 per day without an account, unlimited when signed in), community alerts and the academy courses are free. Paid plans add continuous monitoring, impersonator detection and takedown evidence packs.
