Scams on Facebook Marketplace generally fall into two categories: buyers losing money to fraudulent sellers, and sellers losing their items, money, or account information to fraudulent buyers.
Whether you are buying or selling, start by asking whether the transaction follows normal, reasonable logic. An unusually low price, a complicated payment process, constant pressure to act quickly, or a request to use an unusual transaction method are all reasons to pause and verify the details.
What should buyers watch for?
1. Unusually low prices and small "holding deposits"
A scammer may list a high-value item far below the normal market price, claim that many people are interested, and offer to hold it for you if you send a small deposit—often only $15 or $20.
Because the amount seems minor, many people decide it is worth the risk. But the scammer may be collecting the same small deposit from many buyers before disappearing or deleting the listing.
Do not pay a deposit to reserve an item before you have seen it and verified that the seller actually has it.
2. Check whether the photos and product information are credible
Do not rely on the title alone. Make sure the photos, model, specifications, condition, and description are consistent with one another.
Be cautious when a listing contains only promotional images, blurry photos, a very vague description, or the same photos posted in several different cities. Ask the seller for a new photo showing a specific angle, the serial number, included accessories, or the device powered on. A seller who genuinely has the item can usually provide this.
If the seller avoids specific questions or cannot provide any additional real photos, the item may not be in their possession at all.
3. Review the seller's account
Check how long the account has existed, the number and quality of its ratings, signs of normal activity, and the seller's other listings.
A new account is not automatically fraudulent. However, an account with almost no genuine activity that is simultaneously listing several high-value items at unusually low prices deserves extra caution. Constantly changing locations, reusing the same photos, or posting many nearly identical listings are also warning signs.
4. Be wary of unusual payment methods and attempts to move the conversation off Facebook
Treat requests for gift cards, cryptocurrency, wire transfers, unfamiliar payment links, or other hard-to-recover payment methods as serious warning signs.
A request to continue by text message, WhatsApp, or email is not automatically a scam. However, stop the transaction if the person then sends an unfamiliar link, asks you to sign in to an account, or requests a text-message verification code. Never give anyone a banking code, login code, or identity-verification code.
Keep the main conversation on Facebook whenever possible, and do not use payment or login links sent by the other party.
5. "Brand new and sealed" still needs to be inspected
Intact packaging does not prove that the correct, genuine item is inside. The box may contain a counterfeit, a used or damaged product, or something entirely different from what was advertised.
Before paying for a phone, computer, or other high-value item, verify the model, serial number, accessories, and condition, and perform basic functional tests whenever possible. Tell the seller in advance that you will pay immediately once the inspection is complete.
If the seller insists on being paid before allowing the package to be opened, it is usually better to walk away. Once payment has been made, a dispute over what was inside the box can be extremely difficult to prove.
6. Confirm that Activation Lock has been removed from Apple devices
When buying a used iPhone, iPad, Mac, or Apple Watch, do not stop after confirming that it powers on, displays a welcome screen, or opens the operating system. A device that was stolen, lost, or never removed from its previous owner's account may still be protected by Activation Lock and may be unusable after purchase.
The safest approach is to have the seller sign out of their Apple Account, turn off Find My, and erase the device. You should then activate it at the meeting and connect it to your own Apple Account. Completing this process confirms that the device is no longer tied to the previous owner's account.
7. Check phones for a carrier lock
A phone that connects to Wi-Fi, opens apps, and displays normally may still fail to work with your mobile carrier. Some devices remain locked to a particular carrier and cannot use another carrier's SIM card or eSIM.
Before buying, confirm that the phone is carrier-unlocked and, whenever possible, test it with your own SIM or eSIM. Activation Lock, carrier restrictions, missing accessories, and hidden defects are all possible reasons why a phone may be priced unusually low.
8. Meet safely and preserve the records
Whenever possible, meet during daylight hours in a busy public place with surveillance cameras, or use a designated safe-exchange area near a police station.
Keep a copy of the listing, the complete conversation, the seller's profile, and the payment record. For high-value items, record the model and serial number in case you later need evidence.
What should sellers watch for?
1. Fake electronic payments and shipping scams
A scammer may pose as a buyer and claim that the item is a gift for a friend or child who lives out of town. They may offer to pay the full price and shipping costs in advance.
You may then receive a payment screenshot, an electronic-transfer notice, or an email that appears to come from a bank. Do not ship the item based on any of these alone.
Open your banking app directly and confirm that the money has actually been deposited. Do not follow links in emails or text messages, and do not rely on screenshots supplied by the buyer.
2. Never enter or share verification codes
The buyer may claim that you need to open a link, sign in to online banking, or provide a text-message code to receive the payment, confirm your identity, or upgrade your account.
Receiving a legitimate payment does not require you to give the buyer your banking password, login information, or verification codes. A transaction that asks for any of these is likely an attempt to take over your account.
3. Watch for overpayment and refund requests
A scammer may claim to have accidentally overpaid and ask you to return the difference to another account. The original payment may later prove to be fake or fraudulent, while the money you send back is a real loss.
Do not issue a refund, ship the item, or transfer money to a third party until the payment has been fully confirmed in your own bank account.
4. An in-person buyer may still try to grab the item and run
When selling a phone, computer, camera, or other high-value item, a person may ask to inspect it, take it into their hands, and then run away.
Do not meet in an isolated location, and do not let a high-value item leave your control before payment is confirmed. Choose a monitored public location, bring another person when possible, and review the buyer's account age, ratings, and normal activity before meeting.
5. Keep evidence of the transaction
Save the conversation, buyer profile, payment records, and meeting arrangements. Do not delete messages, move the entire conversation to a platform with no useful record, or accept an untraceable payment method merely because the buyer says it is more convenient.
How can MPReseller help reduce the risk?
MPReseller records information such as a seller's account age, number of ratings, and rating score. When these indicators fall into a range that deserves caution, the system can alert you before you contact the seller.
You can also mark suspicious sellers, sellers you are not interested in, or bulk commercial sellers as ignored. Their listings will then be automatically excluded instead of repeatedly appearing among your target listings.
MPReseller organizes the relevant listings it discovers in one place. If several different accounts post the same item using identical or highly similar photos and descriptions, the repeated pattern becomes much easier to notice.
It also continuously analyzes the number of comparable listings, their price distribution, and the median price. When a listing is far below the normal market range, you can recognize more quickly that it may be a bargain worth investigating—or a price so unrealistic that it signals a scam.
MPReseller can help you spot abnormal prices, duplicated listings, and higher-risk sellers earlier, but it cannot replace inspecting the item, confirming the payment, and judging the person you are dealing with. Whenever the price, process, or pressure feels abnormal, stop and verify before proceeding.
