The Growing OfferUp Fraud Problem

OfferUp processes over 30 million transactions annually, competing with giants like Craigslist, Facebook Marketplace, and eBay. With this volume comes an inevitable influx of fraudulent activity. Understanding these scams is essential for anyone buying or selling on the platform.

Top 10 OfferUp Scams to Watch For

1. Counterfeit Items

High-value items that turn out to be fake are a common trap. Sellers typically push buyers to pay through third-party services like Zelle or Venmo rather than through the app, which removes Purchase Protection coverage.

2. Payment Scams

Scammers exploit third-party cash apps in multiple ways:

- Overpayment fraud: They offer above asking price, overpay using stolen accounts or fake checks, then request a refund
- Gift card scams: Payment via fake or zero-value gift cards
- Out-of-town sellers: Requesting payment for items that never ship

3. Account Takeover

Buyers request verification codes to 'verify' your listing—often through Google Voice. They're actually trying to access your account using your two-factor authentication code. Handing it over gives them complete control.

4. Empty Box Scam

Some sellers hide disclaimers in lengthy descriptions stating they're only selling the box or a digital photo. Buyers receive literally nothing of value.

5. Phishing Links

Messages containing links like "click here to get paid" or "verify your info" lead to phishing sites designed to steal login credentials and payment details.

6. Email and Phone Phishing

Once scammers obtain your email or phone number during transactions, they spam you with malicious links to install malware or harvest information.

7. Deposit Scams

High-value items offered with delivery—as long as you put down a deposit first. The item doesn't exist, and your deposit is gone.

8. Bouncing Checks

Payment via check that bounces days later, leaving sellers without payment or their item.

9. Fake Investment Opportunities

Listings about "investment opportunities" requiring upfront money transfers.

10. Fraudulent Job Posts

Fake employers demanding payment for background checks or requesting personal and financial details for identity fraud.
