Marketplace Scam Warning Signs to Check Before Paying
Warning signs in person-to-person marketplace deals: deposits before viewing, shipping-only pressure, fake payment confirmations, overpayments and off-platform moves.
Person-to-person deals carry person-to-person risk
Marketplaces such as Facebook Marketplace, Kijiji, Craigslist and similar person-to-person platforms mostly connect two strangers and step back. Some offer protected checkout for shipped items; many local deals happen entirely outside any protection. Before You Pay is not affiliated with any of these companies, and the patterns below apply across all of them.
The recurring theme in marketplace losses is money moving before goods do, over a channel that cannot be reversed.
Deposits before viewing
A request to hold an item, a rental or a pet with a deposit is the most common marketplace loss, because it converts a conversation into an irreversible payment with nothing exchanged. Common framings: "several people are interested", "I will stop advertising once you send the deposit", "the deposit covers the courier booking".
If a hold is genuinely needed, propose a platform payment that holds funds, or pay in person at handover. A seller who refuses every option except an immediate transfer is asking you to take all the risk.
Shipping-only pressure and courier stories
The seller who cannot meet
Watch for a seller who is suddenly out of town, deployed, in hospital, or moving abroad, and who therefore needs to ship an item that was advertised as local pickup. The story explains why you cannot inspect the goods and why payment must come first.
Fake courier or shipping agents
You may be sent emails or messages from a "shipping company" confirming that the item is in transit and asking for an insurance, customs or release fee. These messages can look convincing. Verify the tracking number on the courier's own website, typed in yourself, and never pay a fee requested by email to release goods.
Moving the conversation off-platform
An early push to switch to text, email or a messaging app is worth noting. Off-platform conversations are invisible to the marketplace's reporting and dispute processes, and the request sometimes comes with a verification code trick: the other party asks you to send them a code you receive by text, which can be used to take over an account. Never share a code that arrives on your own phone.
Fake payment confirmations and overpayments
Screenshots and emails that look like receipts
If you are selling, treat a screenshot, an email "confirmation", or a pending-payment notice as unconfirmed. Only funds actually visible in your account are real. Fraudulent buyers rely on the pressure of a waiting courier to make you hand the item over before you check.
Overpayment and refund requests
A buyer sends more than the agreed amount, then asks you to refund the difference or pay their "shipping agent". The original payment is later reversed or was never real, and your refund is gone. There is no legitimate reason for a buyer to overpay and ask for a partial refund by a different method.
A simple rule for sellers
Payment requests that remove your recourse
Gift cards have no place in a marketplace deal at all. Requests to send an e-transfer to an address that does not match the person's name, to split payment across recipients, or to use a security question and answer that the other party dictates are all worth pausing on — see the e-transfer warning signs guide if you are in Canada.
Account history and listing quality
Look at how long the account has existed, whether it has other listings, and whether those listings are plausible for one person in one city. Signals worth a question include the same item posted in many cities at once, a profile created this week listing several high-value goods, photos that show a different season or region than the stated location, and prices well under every comparable listing. Our seller checking guide covers reverse image searches and profile checks step by step.
Meeting safely for local deals
If you are meeting in person
- Meet in a busy public place during daylight; many police stations offer exchange zones.
- Bring someone with you, and tell another person where you are going and when.
- Inspect and test the item fully before any money changes hands.
- For vehicles, check identification documents against the ownership paperwork.
- Avoid inviting strangers into your home or going alone to a private address.
- Be prepared to walk away — no deal is worth feeling unsafe.
Using platform protections
Where a marketplace offers a protected checkout, shipping through the platform, or a purchase protection programme, keep the whole transaction inside it — including messages. Protection usually depends on paying through the platform and being able to show the agreed terms. Paying outside it and then reporting a problem rarely qualifies.
Marketplace checklist
Before paying on a person-to-person marketplace
- Do not send a deposit for something you have not seen, unless the platform holds the funds.
- Be sceptical of a local listing that suddenly requires shipping.
- Verify any tracking number on the courier's own site, never through a link you were sent.
- Never pay a release, insurance or customs fee requested by message.
- Keep messages on the platform, and never share a verification code sent to your phone.
- As a seller, wait for settled funds; ignore screenshots and pending notices.
- Refuse overpayment-and-refund arrangements entirely.
- Reverse image search photos and check the account's history and other listings.
- Prefer platform checkout or cash on collection over irreversible transfers.
- Meet in a public place, bring someone, and inspect before paying.
