Online Marketplace Scams: How to Buy and Sell Safely

Online marketplaces have made it easier than ever to buy and sell everything from furniture and electronics to vehicles and household items. Platforms like Facebook Marketplace, Craigslist, OfferUp, and others connect buyers and sellers quickly and conveniently.

Unfortunately, scammers are taking advantage of that convenience, too.

Whether you're selling a used couch or shopping for a hard-to-find item, understanding how marketplace scams work can help you protect your money and personal information.

Why Marketplace Scams Are So Common

Online marketplaces often bring together people who have never met before. Transactions are usually completed quickly, and buyers and sellers may communicate through messages rather than face-to-face conversations.

Scammers take advantage of this environment by creating a sense of urgency, offering deals that seem too good to pass up, or using payment tactics that can be difficult to reverse.

The CFPB identifies urgency, impersonation, requests for sensitive information, and unusual payment methods as common scam warning signs.

The good news is that many marketplace scams follow familiar patterns.

When You're Selling: The Overpayment Scam

Imagine you're selling an item online for $300.

A buyer contacts you and says they've accidentally sent a payment for $500. They apologize and ask you to return the extra $200.

It may seem like an honest mistake, but in many cases, the original payment is fraudulent. Once the payment is reversed or determined to be fake, the money you sent back is gone.

Why it works: The request sounds reasonable and creates pressure to act quickly.

Stay safe: Never send money back based solely on a payment notification. Verify that funds have actually been received and cleared before taking action.

When You're Selling: Fake Payment Confirmations

Some scammers send screenshots, emails, or text messages claiming payment has been completed.

The message may appear to come from a legitimate payment platform and state that funds are pending or will be released once shipping information is provided.

In reality, no payment was ever sent.

Why it works: Fake emails and screenshots often look convincing and use familiar company branding.

Stay safe: Verify payments directly through the payment platform or your account. Never rely on screenshots or forwarded emails as proof of payment.

When You're Buying: Deals That Are Too Good to Be True

You find a brand-new laptop listed for hundreds of dollars below its normal price.

Or a highly sought-after item that's suddenly available for a fraction of what everyone else is charging.

While great deals do exist, scammers frequently use unrealistically low prices to attract attention and pressure buyers into acting quickly.

Once payment is sent, the item may never arrive.

Why it works: The fear of missing out can override healthy skepticism.

Stay safe: Compare prices across multiple listings. If a deal seems dramatically better than every similar listing, proceed carefully.

Requests to Move Off the Platform

Many online marketplaces include messaging systems, safety features, and fraud protections designed to help users.

Scammers often try to move conversations elsewhere as quickly as possible. They may ask to communicate through personal email, text messages, or another app.

By doing so, they can avoid platform monitoring and make suspicious activity more difficult to report.

Why it works: Moving conversations elsewhere often feels more convenient and personal.

Stay safe: Keep communications on the marketplace platform whenever possible until the transaction is complete.

Unusual Payment Requests

Be cautious if someone insists on using an unusual payment method.

Scammers often prefer payment methods that are difficult to reverse, including wire transfers, gift cards, cryptocurrency, or certain peer-to-peer payment services.

The FTC warns that legitimate businesses and government agencies do not require gift cards as payment.

Once money is sent through these methods, recovering funds can be difficult or impossible.

Why it works: Many people are unfamiliar with how payment methods affect their ability to recover funds.

Stay safe: Use secure payment methods whenever possible and be wary of anyone insisting on a specific payment type.

Protecting Yourself on Online Marketplaces

• Meet in a safe, public location whenever possible.
• Trust your instincts if something feels unusual.
• Verify payments independently.
• Be cautious of high-pressure tactics.
• Avoid sharing unnecessary personal information.
• Keep communications on the marketplace platform.
• Research high-value purchases before sending money.

Taking a little extra time to verify a transaction can go a long way toward protecting yourself from fraud.
