OfferUp Scams and How to Sell Safely
OfferUp is a local marketplace, and local marketplaces attract a particular kind of fraud: the sort that depends on meeting a stranger, moving money quickly, or moving the conversation somewhere with no record. None of it is exotic. All of it works on the same handful of gaps.
The scams that actually happen
The fake payment confirmation. A buyer shows you a screenshot, an email, or a text saying the money has been sent. It has not. Screenshots are trivial to fake and the whole scam lives in the gap between "sent" and "arrived." Check your own account, not their phone.
The overpayment and refund. More money arrives than you asked for, and the sender wants the difference back. The original payment is reversed later. There is no honest version of this and it should end the conversation.
The verification-code request. Someone asks you to confirm you are real by sending them a code they have just triggered to your phone. That code is a login or an account setup in your name. Never read a code to anyone.
The move-off-platform push. An immediate request to continue by text, WhatsApp, or email. Every report, record and protection that exists is inside the app. Outside it there is nothing to appeal to.
The counterfeit-goods sale. On the buying side, expensive branded goods at implausible prices, sold locally for cash so there is no route to a refund.
The bait-and-switch at the meet. The item you agreed to is not the item that turns up, and the pressure is to complete anyway because you are both standing there.
The habits that remove most of it
- Meet in a public place, in daylight — ideally at a designated exchange location. Most police departments run one.
- Take cash for local sales, counted before the item leaves your hands. Or a payment you have watched clear in your own account.
- Never send money back, in any amount, for any reason.
- Never share a code that was texted to you.
- Keep every message inside the app, so there is something to show if it goes wrong.
- Use the platform's shipping option for anything not collected in person, so tracking and protection apply.
- Photograph the item as you pack it, with the label visible. That is what settles a not-received claim.
What all of these have in common
Every one of them relies on the buyer and seller never being in the same room as the item at the same time as the money — or on the record of what was said disappearing. Local selling closes the first gap and opens the second: you meet, but nothing is written down anywhere that helps you afterwards.
The other way to close the gap
A live auction is the same trade made in the opposite direction. The buyer never meets you, but they watch the item in your hands, on camera, before they bid — and can ask to see the scratch, the label, the serial number and see it happen. The record is the platform's, not a text thread on someone's phone. Payment runs through the marketplace, so there is a transaction with a history rather than cash and a handshake.
ShopBidz runs live auctions with payment handled in-platform and card processing charged to the buyer rather than the seller. It is not free and local pickup is, which is the honest trade: you are paying for a process and a record.
For a couch collected from your driveway, cash and a public meet is the right answer and no fee is worth paying. For anything shipped, anything valuable, or anything whose condition someone might argue about afterwards, a platform holding the money and the record is worth the rate.
