OfferUp scams: how to spot fraud and buy or sell safely in 2026

OfferUp is one of the biggest peer-to-peer marketplaces in the US, with over 150+ million downloads.¹ Chances are, if you have bought or sold anything used—from furniture to iPhones—there’s a good chance you did it on OfferUp. 

One reason it’s so popular is that, unlike Craigslist (and to a slightly lesser degree, Facebook Marketplace), OfferUp has relatively strong user protections built in. These include profile verification, seller ratings, and an in-app payment system with a dispute process.

Despite this, scams on the platform are common, with fraudsters skirting around in-app safeguards to lead their targets off-platform where the protections disappear.

This guide breaks down every major OfferUp scam circulating in 2026, how each one works, and exactly what to do to protect yourself, whether you're flipping refurbished furniture or hunting for a deal.

Is OfferUp safe?

OfferUp is generally safer than many other peer-to-peer platforms, thanks to its profile verification system, buyer and seller ratings, and in-app payment protection. But "safer" doesn't mean "entirely safe," and the gap between protected and unprotected transactions is exactly where scammers operate.

The core risk on OfferUp isn't the platform itself but your exposure when conducting exchanges off of the app.

OfferUp processes over 30 million transactions per year.² Any platform at that scale will attract bad actors. What distinguishes OfferUp scams from Craigslist or Facebook Marketplace Scams is that they almost universally follow the same patterns and process: 

1. Build just enough trust and confidence in the transaction 
2. Convince you to make payments off-platform 
3. Then exploit the lack of protection

Using OfferUp Payments and conducting communication strictly through the app’s messenger significantly decreases your exposure to this brand of shopping scam. The moment a buyer or seller says "let's just do Zelle" or "Cash App is easier," the safety net is gone.

Most common OfferUp scams

1. Off-platform payment scams

This is the #1 OfferUp scam vector—and the foundation for almost every other scam on this list.

Here's how it works: a buyer contacts you about a listing and quickly steers the conversation toward paying via Zelle, Venmo, Cash App, or PayPal Friends and Family instead of OfferUp's built-in payment system. They'll give you a reason—"OfferUp takes too long to release funds," "I've had issues with the app," or "I prefer sending directly." The real reason is simpler: off-platform payments come with no buyer or seller protection, no dispute process, and no recourse.

Red flags to watch for:

• Any message that immediately asks to move payment outside the app
• Pressure to use PayPal "Friends and Family" specifically (it bypasses PayPal's own buyer protection)
• Offers to pay "extra" if you use their preferred method

2. Fake payment confirmation screenshots

This brand of OfferUp shipping scam specifically targets sellers who live in different cities than buyers.

A buyer says they've paid via Zelle, Venmo, or Cash App and sends you a screenshot or email of the payment confirmation. The screenshot looks completely legitimate, including the exact amount, your name, and a confirmation number. You ship the item. The money never arrives, because the screenshot was edited.

Red flags to watch for:

• Any buyer who insists on CashApp, Zelle, or other payment apps
• Requests to ship immediately after showing a screenshot
• High degree of pressure and urgency to act before you can confirm the funds actually arrived

3. Overpayment scams

This is a very prevalent online marketplace scam. It’s common because it works.

A buyer agrees to your price, then "accidentally" sends more than the asking amount. They ask you to refund the difference. You send the refund. Days later, the original payment reverses (a bounced check, a disputed card charge, or a flagged transfer) and you're out both the item and the money you "refunded."

Always be politely suspicious if someone claims they accidentally sent you more than your asking price, regardless of the form of payment.

4. Verification code requests

A growing tactic used by scammers is to request a verification code. The scammer poses as a buyer and messages you (the seller) requesting a confirmation code to verify your listing. Within minutes, you receive a text from OfferUp with a confirmation code. 

Stop.

What they’re actually doing is trying to gain access to your account and need the code to get past the two-factor authentication. If you share the code, your account can be compromised extremely quickly, along with sensitive personal information held on it.

5. Profile trust manipulation

This one is more sophisticated, and particularly dangerous for high-value transactions.

A scammer builds a legitimate-looking OfferUp profile over weeks or months by completing actual, small transactions. They accumulate five-star ratings and appear to be a verified, trustworthy user. Once the profile looks credible, they use it to either target or lure with a high-value item, such as a phone, a gaming system, or high-end furniture.

From here, the scammer can execute a fake sale or purchase, often incorporating facets of other scam types. It’s often too late by the time you realize what happened. Even though these types of profiles are “real,” they’re by no means legitimate. The ways to spot them are as subtle as the clues that give them away:

How to spot scam profiles:

• A newer account with an unusually high or suspiciously uniform star rating
• Profile age that doesn't match the volume or variety of reviews
• A history of frequent small transactions followed by a sudden interest in buying or selling a four or five-figure item.

6. Fake OfferUp emails and messages

Phishing emails impersonating OfferUp are one of the most common ways scammers harvest account credentials and payment information.

These emails can look official, using OfferUp logo and branding, and typically claim to confirm a payment, notify you of a dispute, or alert you to a security issue. They will prompt you to “verify” your account or confirm a transaction by following a link that leads to a fake site engineered to harvest your login credentials or payment information.

Red flags to watch for:

• Emails claiming to confirm a payment or release funds outside the OfferUp app
• Any link in an email asking you to log in to OfferUp
• Urgent language about account suspension or payment holds

7. Meetup safety risks

As a platform built around local exchange, it makes sense that in-person meetups are part of the platform's DNA. While that’s usually a safety advantage because it lets buyers inspect items and sellers receive cash, it introduces a physical risk calculus that digital-only transactions don't have.

Meeting a stranger to exchange goods is generally low-risk, but not zero-risk. The risk is higher for high-value transactions, evening meetups, and unfamiliar locations.

Best practices for safe in-person meetups:

1. Use OfferUp's Community MeetUp Spots whenever possible
2. Meet during daylight hours in busy public locations
3. Bring a friend to high-value transactions
4. Tell someone where you're going before you leave

How OfferUp's buyer and seller protection works

OfferUp has optional Purchase Protection for transactions made through OfferUp Payments, the platform's built-in payment system powered by Stripe. This protection gives buyers a 48-hour window after delivery to file a claim if a shipped item doesn't match its description or never arrives.

What's covered:

• Items that don't match the listing description
• Items that never arrive
• Empty box delivery scams

What's not covered:

• Any transaction made outside OfferUp Payments (Zelle, Venmo, Cash App, PayPal, etc.)
• Cash transactions, even for local in-person meetups
• Items that violate OfferUp's policies (gift cards, alcohol, prohibited items)

This is the critical gap. OfferUp's protection is very user-friendly, but it has hard boundaries that scammers know exactly how to exploit. That’s why OfferUp scams almost always occur off-platform.

OfferUp safety tips for sellers

1. Only accept OfferUp Payments or cash in person. Those are your two safe options. Anything else (Zelle, Venmo, Cash App, PayPal Friends and Family) removes you from OfferUp's umbrella of protection.
2. Never ship items before a payment clears. A screenshot is not confirmation. A transfer pending is not confirmation. Wait until money is in your bank account before you ship or hand over any item.
3. Meet at Community MeetUp Spots. OfferUp's app shows designated safe exchange locations near you. For high-value items like electronics or furniture, bring a friend and meet during daylight hours. If no designated meetup spot is nearby, select a safe public area with lots of people around.
4. Don't accept unusually high offers. An offer significantly above your asking price is a red flag, not a windfall, and likely the setup for an overpayment scam.
5. Check profile age and review dates. A profile with recent spikes in five-star reviews, or reviews that only cover small, low-value purchases, may belong to a scammer building credibility.

OfferUp safety tips for buyers

Check the seller’s profile age and rating history carefully. Newly created accounts are a statistically higher risk than those with a long history of confirmed transactions. Look at when reviews were posted, not just how many there are.

Never pay outside the app. OfferUp Payments is the only method that gives you recourse; cash is also safe. 

Confirm the payment method upfront. Be prepared to walk away from a listing if a seller pushes Zelle, Venmo, or any other external method. 

Request a video call for high-value purchases. Before committing to an expensive item, ask the seller to show you the item live on a video call. This confirms the item exists, works, and matches the listing.

For local pickup, use OfferUp's Community MeetUp Spots. They're mapped in the app and exist specifically for safe exchanges. If none are in your area, meet at a popular public area, and always in daylight.

If a deal looks too good to be true, it probably is. Scammers use artificially low prices to create urgency and override your better judgment. If a $600 iPhone is listed for $150, there's a reason.

Inspect items before payment for local transactions. One of the benefits of in-person exchange is that you can verify what you're buying. Remember: you’re not obligated to buy anything, so if the item doesn’t match the description, don’t hand over your money.

What to do if you were scammed on OfferUp

Act quickly. The faster you move, the better your chances of limiting the damage.

1. Report to OfferUp immediately. There are multiple ways to report a scammer on OfferUp. The platform makes it easy to do so via the app or desktop, and from the person’s profile, chat, or suspicious listing.

If you paid through OfferUp Payments, file a Purchase Protection claim through the OfferUp Help Center. For fraudulent shipments, the 48-hour window from delivery applies.

2. Contact your bank or payment app. If you paid via a credit or debit card, call your bank and request a chargeback. If you paid via a cash app like Zelle or Venmo, contact them directly. Recovery is unlikely but may help flag and ban the scammer's account.

3. File a report with the FTC. Go to ReportFraud.ftc.gov to file an official fraud report. In 2024, consumers reported over $12.5 billion in losses to fraud.³ Reports like yours help the FTC identify trends and take enforcement action.

4. File a complaint with the IC3. The FBI's Internet Crime Complaint Center (ic3.gov) handles internet fraud reports and can act on cases that cross state lines or involve large losses.

5. Change your credentials. If you clicked any links or entered your OfferUp password anywhere, change it immediately. Use a unique new password and enable two-factor authentication.

6. Monitor for follow-up phishing. Scammers who have your contact information may attempt follow-up attacks. Be alert for emails or messages claiming to be from OfferUp, your bank, or "fraud recovery" services.
