Spam calls: how to tell if a number is spam
Signs a phone call is spam or a scam, what to check before calling back, and where to report it.

Warning signs
Pressure to act immediately, requests for payment by gift card, wire or crypto, threats of arrest, or requests for codes sent to your phone are classic scam signs.
Before you call back
Look the number up, but remember that a clean result doesn't mean a call is safe, and a reported number may have been spoofed. Never call back a number left in a suspicious voicemail; use an official number instead.
Reporting
Reports to the FCC and FTC help regulators find patterns and take action, even if they can't respond to each complaint individually.
