Tired of robocalls? Look up any number for free below — ScamGuard tells you who's calling and whether it's a known scam in seconds. Then use the guide below to block and report.
Block the number on your device, enable carrier spam filtering, register on Do Not Call (US: 1-888-382-1222), and never press a button or speak when prompted — that confirms your number is active. Use ScamGuard to look up unknown callers before answering.
Yes. Paste any number into ScamGuard's free phone checker — we cross-reference community reports, carrier blocklists and known scam patterns to tell you instantly if it's spam.
Your number has likely leaked from a data breach, a sweepstakes entry, or a public listing. Scammers buy these lists by the millions and auto-dial. Blocking individual numbers helps, but registering on Do Not Call + carrier filtering cuts the most volume.
Never. Some scams record you saying 'yes' and splice it into recordings to authorize charges. Don't talk to robocalls at all — hang up.
Settings → Phone → Silence Unknown Callers (toggle on). For known spammers: tap the number → scroll down → Block This Caller. Combine with your carrier's spam filter app.
US: FTC at reportfraud.ftc.gov and FCC at fcc.gov/complaints. Globally: report to ScamGuard so other users get warned about the number.
