An OfferUp buyer or seller pushes you off the app, asks you to “hold” an item after a fake overpayment, or insists on Zelle, Cash App, wire, or gift cards instead of meeting locally or using OfferUp’s payment tools. A related script sends a too-large “cashier’s check,” then demands you refund the difference before the check bounces. Same local-marketplace patterns as Fake Facebook Marketplace scams and Fake Craigslist wire scams.
Seller-impersonation / off-platform payment cousins: Fake OfferUp seller impersonation scams. Gift-card and prepaid traps: Gift cards and prepaid debit risks. Broader consumer fraud: Credit and debt scams.
Scripts to expect
| Script | Hook | Goal |
|---|---|---|
| Off-app payment | “Meet canceled—just Zelle / Cash App / Venmo Friends & Family” | Irreversible payment; item never ships or never exists |
| Overpayment / fake check | Buyer “accidentally” pays extra; asks you to refund via wire or gift cards | Check bounces; you ate the refund (eBay overpayment cousins) |
| Shipping bait on a local listing | “I’m out of town—ship with my courier label” | Fake labels, empty boxes, or stolen account identity |
| Deposit to “reserve” | Seller wants a deposit before a public meetup | Ghost after you send money |
| Fake OfferUp support | “Release escrow with Apple gift cards” | Drain cards; OfferUp support does not work that way |
Local cash-at-meetup deals for small items reduce remote payment risk. For anything larger, prefer platform-native tools and public meetup spots—never a stranger’s parking garage at midnight with a wire receipt.
Red flags
- Pressure to move to WhatsApp, SMS, or email and pay before you see the item.
- Payment methods the other party “only” accepts: gift cards, crypto, wire, Friends & Family P2P (Zelle and P2P scams).
- Checks or money orders for more than the asking price.
- Refusal to meet in a well-lit public place (police-station parking lots and busy retail lots are common safe choices).
- URLs or apps that are not OfferUp’s official site / store listing.
- “OfferUp Support” that messages you first and needs gift-card PINs.
Worked example: the overpayment meetup switch
Jordan lists a used bike for $450 on OfferUp. A buyer offers $500 via a “cashier’s check” from a credit union Jordan has never heard of, claims their assistant will pick up, and asks Jordan to Zelle $50 change plus a $75 “courier fee” to a phone number. Jordan deposits the check at Bank of America; funds look available in two days. Jordan Zelles $125. A week later the check is returned unpaid. Jordan is out the bike (if handed over) or the $125 (if not)—and the OfferUp chat account is gone.
Jordan’s recovery path: stop sending money; tell the bank’s fraud desk immediately; report the OfferUp profile through the app; file ReportFraud.ftc.gov; do not “verify” with a second payment. Safer path would have been: cash or on-platform payment at a public meetup, no refunds of overages, no shipping for a local listing.
Safer meetup and payment habits
- Keep the conversation in OfferUp until you decide to meet; be wary of anyone who refuses the app’s tools entirely.
- Meet in public; bring a friend for higher-value items; trust your exit plan.
- Prefer cash for small local deals or OfferUp’s supported payment flows for remote/shipping—confirm current options in the official app.
- Never accept overpayment. Never refund before a check fully clears (availability ≠ cleared).
- Reverse-image search serial-number photos when buying electronics; walk away from “too good” new-in-box deals from brand-new accounts.
Named institutions and brands that show up in these scripts include OfferUp, Zelle, Cash App, Venmo, Western Union, MoneyGram, Apple gift cards, Google Play, Walmart / Target money-transfer kiosks, and major banks’ mobile deposit features. None of those are a reason to ignore overpayment math.
If you already paid or shipped
- Contact your bank or card issuer the same day; ask about recalls and fraud claims.
- Preserve OfferUp chat exports, tracking numbers, and payment receipts.
- Report the user in-app and to FTC ReportFraud; consider a local police report for large losses.
- Do not pay a “recovery agent” who cold-contacts you afterward.
Checklist
- Treat off-app payment pressure as a warning, not a convenience.
- Never refund an overpayment before funds irrevocably clear.
- Skip gift cards, wires, and Friends & Family P2P for strangers.
- Meet locally in public for cash deals when that fits the item.
- Verify shipping labels and buyer identity before you drop a package.
- Report scams so OfferUp and the FTC can pattern-match accounts.
