How do scams work on OfferUp and local selling apps?
Local selling apps like OfferUp, Letgo, and similar platforms are targeted by fake payment apps, impersonation of the platform's payment systems, and shipping scams that bypass the safety of in-person cash transactions.

Explanation
Apps designed for local peer-to-peer selling share many of the same scam patterns as Facebook Marketplace and Craigslist, with some platform-specific variations. OfferUp, for example, has an integrated payment system called TruYou and offers Payments by OfferUp for shipped items — both of which provide more safety than off-platform payment methods. Scammers therefore work to route transactions away from these protected channels.
One common tactic is the external payment request: a buyer insists they will pay through Zelle, Venmo Friends, or a payment app the platform does not support, often offering a slight premium to compensate. Once the seller accepts and releases the item, the payment either never arrives or is reversed. The premium was an incentive to bypass the very protection that would have given the seller recourse.
Fake in-platform payment confirmations are also used: a buyer shows a screenshot purporting to be an OfferUp Payment confirmation. Sellers who check their own app balance rather than trusting screenshots are protected against this; those who trust the screenshot lose the item with no payment.
For shipped items, sellers face the risk of buyers claiming non-delivery and seeking refunds for items that were delivered. Using shipping with tracking and signature confirmation, and documenting the condition of items before shipping, protects sellers in dispute processes.
Common red flags
- Buyer wants to pay via a method outside the app's official payment system
- Buyer shows a payment screenshot but your in-app balance shows no change
- Buyer offers to pay more than asking price in exchange for using an external payment method
- Buyer or seller wants to complete the transaction over text or WhatsApp rather than in the app
- Item is priced dramatically below market value with the seller showing urgency to sell quickly
- Buyer files a false not-received claim for a shipped item that tracking confirms was delivered
What to do now
- Use the platform's official payment system for all transactions — it provides the best dispute protection
- For in-person transactions, meet in a public place and verify actual cash or confirmed in-app payment before releasing items
- Never rely on screenshots as proof of payment — check your own app balance
- For shipped items, use tracked shipping with signature confirmation and photograph items before packing
- Report scam buyers and sellers in-app and to the platform's trust team
- For payment disputes on shipped transactions, use the in-app dispute process promptly
Frequently asked questions
Is it safer to meet locally or ship on OfferUp?
Local in-person cash transactions carry the lowest risk when both parties follow safety practices. Shipping introduces additional complications but is covered by OfferUp Payments dispute protection when you use the in-app payment system.
What are safe meeting locations for local app transactions?
Many police departments offer Safe Exchange Zones in their parking lots specifically for this purpose. Banks, busy coffee shops, and well-lit public spaces during daylight hours are also good choices. Avoid meeting at your home or the buyer's home.
