Real scam examples

IRS impersonation

Caller from a spoofed US number says you owe back taxes and threatens arrest unless paid in gift cards. The IRS never calls and never accepts gift cards.

WhatsApp 'recruiter'

International number messages an unsolicited 'job offer' on WhatsApp. Almost always a task-scam funnel — look up the number first.

Enter any phone number (US, international, WhatsApp). ScamGuard checks it against our community-reported scammer database, identifies the carrier and country, and returns a risk score with the report history.

What numbers should I look up?
