Frequently asked questions

How do I lookup a scammer's phone number for free?

Paste the number into ScamGuard's free phone checker above. We cross-reference community reports, carrier blocklists, and known scam patterns and return a verdict in seconds — no signup needed.

Is the phone number lookup really free?

Yes. Free for individual checks, no credit card, no signup. Premium covers bulk lookups, API access and deeper investigations.

Can I find out who owns a phone number?

ScamGuard tells you whether a number is a known scammer, what kind of scam it's been linked to, and how many people have reported it. We don't expose private identity data — only the scam pattern.

What if my number isn't in the database?

If we have no record, you'll see 'no known reports'. That doesn't mean safe — it means new. Treat any unsolicited call asking for money, OTPs or personal info as suspicious until proven otherwise.

Should I call back unknown numbers?

No. Look them up first. If it's a scam, calling back can confirm your number is active and trigger more spam. ScamGuard is designed to make that lookup take 5 seconds.

How do I report a scam number?

After checking it, hit Report. Verified reports help warn other users — usually within minutes.
