These scam types account for 95% of marketplace fraud in 2026.

1. Fake Payment Confirmation Scam

How it works:

2. The Overpayment Scam

How it works:

Real example: A Texas seller listed a couch for $350. "Buyer" sent $550 via Zelle, claimed they meant to send $350, asked seller to refund $200. Seller sent $200 back. Original $550 payment bounced 3 days later (stolen bank account). Seller lost $200 cash.

3. Fake Shipping Protection Scam

How it works:

Real example: An OfferUp seller lost a $700 PlayStation 5. They received an email from "[email protected]" with prepaid shipping label. They shipped console, then discovered OfferUp never sent the email—scammer created fake Gmail account with OfferUp branding.

4. The Google Voice Verification Code Scam

How it works:

Real example: A Craigslist seller of a free couch received this request. Thinking it was spam protection, they shared the 6-digit code. Scammer used it to create Google Voice number that was later used in fraud schemes—police initially investigated the original seller.

5. Bait-and-Switch (Counterfeit Items)

How it works:

Real example: Facebook Marketplace buyer paid $400 for "authentic Gucci handbag" (retail $1,800). Listing had professional photos.

6. The Remote Job/Work-From-Home Scam

How it works:

Real example: A job seeker in California responded to "$1,500/week data entry" post. "Employer" mailed $3,000 check to buy "software and laptop." Applicant deposited check, wired $2,800 to "equipment supplier." Check bounced 5 days later—applicant owed bank $2,800.

7. The Fake Escrow Service

How it works:

Real example: A Craigslist car seller agreed to use buyer's "recommended escrow service" for $8,000 transaction. Seller created account, verified identity, signed title digitally. Money never arrived—website was elaborate fake that collected seller's identity documents (used later for identity theft).

8. The Fake Rental Listing

How it works:

Real example: A family lost $2,400 on fake Los Angeles rental. Listing had 20+ photos, detailed description, $1,600/month (market rate: $2,800). "Landlord" said they were in Europe, asked for deposit via Zelle to "hold it." Family sent money, showed up with moving truck—real owners called police.

9. Ticket Scams (Concerts, Sports, Events)

How it works:

Real example: Taylor Swift concert tickets ($600/pair) listed on Facebook Marketplace for $400. Buyer paid via Venmo, received mobile ticket screenshots. At stadium, tickets scanned as "already used"—original owner had screenshotted tickets before "selling" them. Buyer lost $400 + missed concert.

How to avoid:

10. The "Buy Now, Pick Up Later" Scam (Fake Buyers)

How it works:

Real example: Seller listed washer/dryer set for $800. "Buyer" sent fake Zelle confirmation email, said sister would pick up in 3 days. Seller marked sold, declined 5 other interested buyers. Day 3: No show, no response. Fake email, no payment. Seller had to relist and lost 3 days of potential sales.

FAQ

How can I tell if a Facebook Marketplace seller is legit?

Check: 1) Profile has personal posts/photos (not just selling), 2) 10+ reviews from different buyers, 3) Reviews span several months (not all recent), 4) Seller responds to questions about the item specifically, 5) Willing to meet in public place. If profile is empty or all-selling with recent reviews, high scam risk.

What's the safest payment method for Craigslist?

Cash in-person for local transactions. For shipped items or high-value purchases, use PayPal Goods & Services (buyer protection). NEVER use wire transfer, gift cards, or Zelle for Craigslist transactions.

Can I get my money back if scammed on OfferUp?

If you paid using OfferUp's in-app payment system, file a claim via Help Center within 2 days. Success rate is 60-70%. If you paid outside the app (Venmo, Zelle, cash), OfferUp can't help—contact your payment provider directly. Use OfferUp Payment for buyer protection.

How do I verify if a listing is a scam before buying?

Run reverse image search on listing photos (Google Images). If photos appear on dealer sites or other listings, it's likely fake. Check seller's profile age, reviews, and response time. Ask specific questions about the item—scammers give generic answers. Request additional photos with unique details.

What should I do if a Poshmark item arrives fake?

File a claim within 3 days of delivery: Order Details > Problems/Order Inquiry > Item is not authentic. Provide photos of tags, serial numbers, and quality issues. Poshmark will review and issue refund if confirmed fake. Do NOT rate the order before filing claim.

Is it safe to meet at a seller's home?

Generally avoid it for small items. If necessary for large furniture/appliances, bring a friend and inform someone of location. Meet during daylight hours. Trust your instincts—if home feels unsafe or seller seems sketchy, leave immediately.

How can I spot fake PayPal payment emails?

Log into PayPal app/website directly—never trust email alone. Real PayPal payments appear instantly in your account (not "pending" or "on hold"). Check sender email domain (@paypal.com, not @gmail.com). Hover over links (don't click)—real PayPal links go to paypal.com only.

What's the Google Voice verification code scam?

Scammer initiates Google Voice setup using YOUR phone number. Google texts you 6-digit code. Scammer asks you to share code "to verify you're real." If you share it, they complete setup and now have Google Voice number tied to your phone—used for other scams that trace to you. NEVER share verification codes.

Can I get scammed picking up free items?

Yes. Scams include: 1) "Free" item but seller demands cash at pickup, 2) Address is vacant home (trespassing setup), 3) Seller asks for Google Voice code "to verify", 4) Meet location is remote area (safety risk). For free items, still meet in public place and bring a friend.

How do I report a scammer to prevent others from being scammed?

Report on platform (Flag user/Report listing). File with IC3.gov (FBI Internet Crime). Post on r/Scams subreddit with details. Leave reviews warning others. Report to FTC: reportfraud.ftc.gov. Local police (if loss > $500). The more places you report, the more visibility authorities have.

Conclusion

Marketplace scams cost $800 million annually, but 95% are preventable with basic awareness. Fake payment confirmations, overpayment schemes, and counterfeit items are the most common threats across Craigslist, OfferUp, Facebook Marketplace, and other platforms.

Key takeaways:

The best defense is prevention: verify sellers, inspect items thoroughly, and never rush transactions. One hour of caution saves hundreds of dollars in losses.
