Frequently asked questions

Can you tell me exactly who called me?

No. We don't identify individuals. We show risk signals, network information, and aggregated reports to help you decide whether a call is suspicious.

Why is this phone number flagged as risky?

A number may be flagged due to scam reports, call patterns linked to fraud, or known scam campaigns reported by the community.

Does a "safe" result mean the call is legitimate?

Not always. Scammers frequently rotate numbers. Treat results as a warning signal and stay cautious if the call pressures you to act quickly.

How do I report a scam call?

Use the report option on the page to help warn others. Reports are aggregated and reviewed to reduce misuse.

What should I do if I answered or called back?

Don't share personal details. If payment or account access was involved, contact your bank or provider immediately.
