Peak Season
Year-round; spikes around back-to-school and holiday shopping seasons
Scammers operate on both sides of online marketplace transactions. As sellers, they list items that don't exist (or list real items at too-good-to-be-true prices), collect payment via P2P apps, and never ship anything. As buyers, they send fake payment confirmations, overpay with fraudulent checks, or use stolen credit cards. The core problem: Zelle, Venmo, and CashApp are designed for sending money to people you know and trust — they offer virtually no buyer protection for marketplace transactions, and transfers are instant and irreversible.

[Facebook Marketplace message] Hey! I'm interested in the PS5. I'm out of town for workRed flag: Classic excuse to avoid meeting in person — removes your ability to verify the buyer but I can send you $450 on ZelleRed flag: Pushing for Zelle because it's instant and irreversible — the fake payment confirmation email will come next right now if you can hold it for me. My wife will pick it upRed flag: Third-party pickup adds another layer of distance from the scam this weekend. What's your Zelle email?
[Fake Zelle notification email] From: notify@zelle-transfer-confirmation.comRed flag: Not a real Zelle domain. Real Zelle notifications come from your bank's app or email system, not from Zelle directly. You have received a payment of $500.00 from David Miller. The funds are being held and will be released once you upgrade to a Zelle Business accountRed flag: There is no 'Zelle Business upgrade' that requires the seller to pay. This is entirely fabricated.. To complete the upgrade, ask the sender to send an additional $200Red flag: Classic advance-fee trick — you send real money to 'release' fake money for the business account fee, which will be refunded to you.
Buyer or seller insists on Zelle/Venmo/CashApp instead of platform payment
P2P apps have no buyer/seller protection. Platform payment systems (like Facebook's checkout or PayPal Goods & Services) offer dispute resolution.
Price is significantly below market value
If a $1,200 item is listed for $500, it's almost certainly a scam or stolen goods
Seller refuses to meet in person for local pickup
Legitimate local sellers are willing to meet in a public place. Always do the exchange in person at a police station or bank lobby.
Buyer sends payment confirmation via email (not in the app)
Real Zelle payments show in your bank account immediately. If you only have an email 'confirmation' but no money in your account, it's fake.
Buyer overpays and asks you to send back the difference
The overpayment is fake (bad check, stolen card). The 'refund' you send back is your real money.
Real Zelle payments appear directly in your bank account — not via a separate email. Real Venmo and CashApp payments show in the app with the money available immediately. Legitimate marketplace buyers are willing to meet in person, inspect items, and use platform-protected payment methods. No real payment system requires a 'business upgrade fee.'
Usually not. These apps explicitly state they're for sending money to people you know and trust. If you authorized the payment (even if you were tricked), the apps generally won't reverse it. This is why scammers insist on P2P — it's essentially cash.
Reviews can be faked, bought, or belong to a legitimate account that was hacked. Don't rely on reviews alone. Insist on meeting in person for local transactions, and use platform-protected payment for shipping transactions.
Sharing your Zelle email/phone for receiving payment is generally okay — they can't steal money by sending you a payment. The danger is fake payment confirmations (emails that look like Zelle but aren't). Always verify the money is in your actual bank account before releasing any item.
