Frequently Asked Questions

How can I tell if a Facebook Marketplace listing is a scam?

Look for these warning signs: prices significantly below market value, sellers demanding cash-only or Zelle/Venmo payments, urgency pressure ("must sell today"), refusal to let you test the item, only one photo or stock photos, newly created seller accounts, and suggestions to meet in isolated locations. SafeOrStolen's AI scam checker analyzes all of these signals automatically and gives you a 0-100 risk score.

What should I do if I think a listing is a scam?

Do not send any money or personal information. Report the listing to the platform. If you've already sent money, contact your bank immediately to dispute the charge. File a report with the FTC at reportfraud.ftc.gov and your local police department.

Is it safe to buy from Facebook Marketplace?

Facebook Marketplace can be safe if you take precautions: always meet in a public place, test items before paying, use Facebook's checkout system when available, verify the seller's profile age and history, and use SafeOrStolen to check both the item's stolen status and the listing's scam risk score.

How common are scams on Craigslist and OfferUp?

According to the FTC, Americans lost over $10 billion to fraud in 2023, with online marketplace scams among the fastest growing categories. Craigslist has no buyer protection system at all. Using SafeOrStolen's AI scam checker before any purchase reduces your risk significantly.

Does SafeOrStolen check if items are stolen AND if listings are scams?

Yes. SafeOrStolen is the only platform that does both. The stolen item check verifies IMEI, VIN, and serial numbers against 100+ databases. The AI scam checker analyzes the listing itself for fraud signals. Use the Marketplace URL Analyzer for BOTH checks simultaneously.

Also Check if Items Are Stolen

The scam checker analyzes the listing. The stolen checker verifies the actual item. Use both for complete protection.
