What Is OfferUp and How Does It Work?
OfferUp is a mobile-first marketplace where people buy and sell items locally and through shipped listings. Founded in 2011 and merged with competitor Letgo in 2020, OfferUp is one of the largest peer-to-peer marketplaces in the US, with tens of millions of users buying and selling furniture, electronics, vehicles, clothing, and more.
OfferUp is a real company with a real app and real infrastructure. It is not a scam platform. But like any peer-to-peer marketplace — Craigslist, Facebook Marketplace, Poshmark — you're buying from individual sellers, not from OfferUp itself. The platform facilitates the transaction, but the quality and safety of each deal depends on the individual seller. Understanding this distinction is the key to using OfferUp safely.
OfferUp offers two types of transactions: local deals where you meet the seller in person, and shipped deals where the seller mails the item. Each carries different risks, and each requires different safety strategies.
Is OfferUp Legit? The Short Answer
Yes, OfferUp is a legitimate company. It processes payments through its platform for shipped items and holds funds in escrow until the buyer confirms receipt. For local deals, payment is typically handled in cash or through the app's payment system. OfferUp has buyer protection for shipped purchases — if an item doesn't arrive or doesn't match the listing, you can file a claim and receive a refund.
However, "legitimate platform" does not mean "every seller is trustworthy." OfferUp hosts millions of individual sellers, ranging from professional resellers to people cleaning out their garage. Most are honest, but a minority are scammers — and because the platform is open to anyone, the burden of vetting sellers falls largely on you, the buyer.
The platform's rating and review system helps, but it's not foolproof. Scammers can create new accounts, build fake positive reviews, or exploit the local-deal format where ratings matter less. The key is knowing which red flags to watch for and which payment methods are safe.
Common OfferUp Scams to Watch For
Fake payment scams: When you're the seller, a buyer may send a fake "payment received" screenshot or email claiming they've paid through OfferUp or Zelle, pressuring you to ship the item before the payment actually clears. Real OfferUp payments appear in the app — not in a text or email screenshot. If you don't see the payment in your OfferUp account, it didn't happen.
Off-platform payment requests: A scammer may ask you to pay through Venmo, Cash App, Zelle, PayPal Friends & Family, or cryptocurrency instead of through OfferUp's in-app payment system. This is always a red flag — off-platform payments strip away all buyer protection. If you pay through Zelle and the item never arrives, OfferUp can't help you. Always use OfferUp's built-in payment system for shipped items.
Overpayment scams: A buyer "accidentally" sends you more than the asking price and asks you to refund the difference through a separate payment method. The original payment is fake, but your refund is real — and gone for good. Never refund an overpayment; simply return the full amount through the same channel it came from.
Counterfeit or misrepresented items: Especially with electronics, sneakers, and designer goods, sellers may list counterfeits as authentic or significantly exaggerate the condition. For high-value items, ask for detailed photos, serial numbers, and proof of authenticity before buying.
Safety Tips for Local OfferUp Deals
For local, in-person transactions, the risks are different but equally important:
1. Meet in a public, well-lit place — ideally a designated "safe exchange zone" at a local police station. Many police departments offer their parking lots as safe meeting spots for marketplace transactions. 2. Never go alone, especially for high-value items. Bring a friend or family member. 3. Inspect the item thoroughly before handing over any money. Test electronics, check for damage, and verify that the item matches the listing.
4. Pay in cash or through the OfferUp app — never through a third-party payment app a seller requests. 5. Trust your instincts. If the seller refuses to meet in a public place, insists on coming to your home, or pressures you to act quickly, walk away. 6. Tell someone where you're going and who you're meeting before you head out.
Safety Tips for Shipped OfferUp Deals
For shipped purchases, follow these guidelines:
1. Check the seller's profile — look at their rating, number of completed sales, and reviews from other buyers. A seller with hundreds of positive ratings is far less risky than a brand-new account with no history. 2. Always pay through OfferUp's in-app payment system, which holds your money in escrow until you confirm receipt. Never agree to pay through Venmo, Cash App, Zelle, or any other method — this voids your buyer protection entirely. 3. Inspect the item immediately upon delivery and file a claim through OfferUp if it doesn't match the listing. Don't confirm receipt until you've verified the item.
4. Be skeptical of deals that are significantly cheaper than market value. If a current-model iPhone is listed for half its retail price, something is wrong. 5. Never share your OfferUp password, verification codes, or personal financial information with a seller. 6. If a seller sends you a link to pay or "verify" outside the app, don't click it — run it through Scam Detective first.
