If you received a scam call, please submit the number that called you.
That's why we built Pynder - to crowdsource and track scam call data.
Pynder was founded by a concerned group of American citizens with over 75 years combined experience in telecom and web tech. We began investigating scam calls in May 2025 and quickly realized the scale of the problem demands community involvement.
Scammers are running wild. The reverse lookup tools? Mostly smoke and mirrors.
Some even fuel the fire—harvesting data, misdirecting searches, and selling your curiosity back to you.
Pynder relies on crowdsourced reports to uncover patterns behind scam operations.
Right now, we’re collecting and storing call and number data to support a larger investigation.
We don’t collect your personal info. Ever.
We collect basic technical metadata such as IP address and browser information to prevent abuse. We do not store personally identifying information.
If you're here, odds are a strange number has called your phone. Maybe it claimed to be your bank. Or your mother. Or the IRS. Spoiler: it wasn't.
Scammers use tricks called Caller ID Spoofing and Neighbor Spoofing - stealing real numbers to trick real people. A reverse lookup just tells you who owns the number, not who called you. That’s the misdirection. That’s the trap.
We collect scam call info from people like you to find patterns, trace footprints, and expose the underlying networks.
These criminals prey on society - particularly the elderly and infirm. Our long term mission is to spread awareness and stop as many scams as possible.
Why should you care? Cuz, fuck these guys!
We're just getting started, but here's what we’re building:
Open-source scam call tracking & visualization.
Deeper investigation tools for volunteer gumshoes.
A shared repository of findings.
