Is OfferUp a Scam? Your 2026 Guide to Avoiding Nikon Z9 Mark III Scams

Google Voice Verification Code Scam: Scammers may ask you to "verify" yourself by sending them a code sent to your phone. This code is often used to set up a Google Voice number, which they then use for fraudulent activities. OfferUp's official verification process, TruYou, does not involve sharing verification codes.

Fake Payment App Screenshot Scam: A scammer might show you a convincing-looking screenshot of a payment confirmation, but no money has actually been transferred. Always verify funds directly in your own payment app or bank account before completing a transaction.

Shipping Label Outside App / Shipping Scams: Be wary if a seller insists on handling shipping outside of OfferUp's integrated system. Scammers may provide fake shipping labels or tamper with labels to divert packages. Always use OfferUp's shipping options for transactions involving delivery to ensure you have recourse.

The 'Text Me' Phone Number Phish: Scammers often try to move the conversation off the OfferUp platform by requesting your phone number to text you. This is to bypass OfferUp's security measures and potentially phish for personal information or engage in other scams. Stick to OfferUp's in-app messaging.

Empty Box Shipping Fraud: This scam involves receiving an empty box instead of the purchased item, often with tracking information that shows the package was delivered. Documenting the unboxing process and using OfferUp's integrated shipping and payment system can help mitigate this risk.

Non-Existent Item Deposit Scam: Sellers might ask for a deposit to secure a high-value item like a Nikon Z9 Mark III, only for the item to never materialize. Never pay a deposit outside of OfferUp's secure payment system for items you haven't received or inspected.

Fake TruYou Identity Theft: Be cautious of requests for personal information beyond what's necessary for a transaction. Scammers may impersonate OfferUp support or ask for details on external sites to steal your identity. Always verify communication comes directly from OfferUp within the app.

Overpayment via Cashier's Check Scam: A buyer might claim to have overpaid and request a refund of the difference. The initial payment, often via a fake cashier's check, will eventually bounce, leaving you out the item and the refunded amount. Only accept payments through OfferUp's secure system.

Robbery at Unsafe Meetup: High-value items like the Nikon Z9 Mark III can attract individuals with malicious intent. Always arrange meetups in well-lit, public, and safe locations, preferably with security presence. Never meet in isolated or private areas.
