Craigslist & Marketplace Scams: 7 Red Flags and How to Stay Safe

Selling that old couch on Facebook Marketplace or browsing Craigslist for a deal? You're not alone — millions of transactions happen on peer-to-peer platforms every day. Unfortunately, scammers know this too. Here are the 7 most common scams in 2026 and exactly how to dodge them.

1. The Fake Payment Confirmation

The buyer claims they've sent payment via Zelle, Venmo, or Cash App and sends you a screenshot as "proof." The screenshot is fabricated. They pressure you to ship immediately.

Red Flag	What's Really Happening
Screenshot only, no actual transfer	Photoshopped confirmation
"Bank is processing, give it a few hours"	Stalling tactic
Urgency to ship right away	Getting the item before you check

What to do: Always verify payment directly in your bank or payment app. Never rely on screenshots.

2. The Overpayment Scam

A buyer sends a check for more than the asking price and asks you to wire back the difference. The original check bounces days later, and you're out the money you sent.

• Never accept overpayment
• Don't wire money to strangers
• Cashier's checks can be forged — verify with the issuing bank directly

3. The Phishing Link

"I've made payment through Marketplace's secure system. Click here to confirm." The link leads to a fake login page that steals your credentials.

Rule: Legitimate payment confirmations appear inside the platform's app or official website. Never click links from iMessage, SMS, or email claiming to be from Marketplace.

4. The Fake Shipping / Delivery Service

The "buyer" wants to arrange a private courier and sends you a fake email confirming payment is held in escrow. No real money was ever sent.

How to spot it

• Unfamiliar delivery service names
• Emails from free email providers (Gmail, Yahoo) posing as companies
• Requests to pay shipping fees upfront

5. The Too-Good-to-Be-True Listing

Brand new iPhone for half the retail price? Concert tickets at 70% off? If the price seems impossibly low, it's probably a scam.

Check	Why It Matters
Price vs. market value	Unrealistic discounts = bait
Account age	New accounts are higher risk
Photo reverse search	Stolen product photos from retail sites
Willingness to meet locally	Scammers avoid face-to-face meetings

6. The Rental Scam

Fake landlords list apartments they don't own, collect deposits and first month's rent, then vanish. They copy real listings and lower the price to attract victims.

• Never pay a deposit before seeing the property in person
• Verify ownership through public records
• Be suspicious of landlords who are "out of town" and can't meet

7. The Personal Information Harvest

The "buyer" or "seller" asks for your full name, address, date of birth, or ID "for verification." This data goes straight to identity theft operations.

Never share: Social Security numbers, driver's license photos, or banking credentials with anyone on a classifieds platform.

Safe Selling Checklist

1. Stay on the platform — Moving to WhatsApp, Telegram, or text is a warning sign
2. Meet in public — Police station parking lots, coffee shops, or other well-lit areas
3. Cash or platform payments only — Avoid wire transfers, gift cards, and crypto
4. Verify before shipping — Confirm payment clears in your account
5. Document everything — Save conversations, receipts, and photos

Sharing Sensitive Info During a Transaction

Sometimes you legitimately need to share an address, account number, or access code with a buyer or seller. Don't paste it directly in a chat where it lives forever. With LOCK.PUB, you can create a password-protected link that expires automatically. Only the person with the password can view it, and it disappears after the set time.

What to Do If You've Been Scammed

• Report to the platform — Use the built-in reporting feature
• File a police report — Especially for amounts over $500
• Report to the FTC — reportfraud.ftc.gov
• Contact your bank — If payment info was compromised, freeze the account immediately

Bottom Line

Scammers thrive on urgency, off-platform communication, and your trust. Taking an extra two minutes to verify can save you hundreds or thousands of dollars. When you need to share sensitive details during a transaction, use encrypted tools like LOCK.PUB to keep your information safe.

If it feels too good to be true, it is.
