The Overpayment Scam: How Seniors Are Tricked Into Sending Their Own Money

The short version: A stranger sends you more money than they owe, asks you to wire the difference back or buy gift cards — and by the time you discover their check is fake, your real money is already gone. This scam costs Americans billions each year, and seniors are the most targeted group.

Here is what you need to know to protect yourself.

Why This Scam Works So Well

The overpayment scam succeeds because it exploits something we all learned as children: if someone accidentally gives you too much, you give back the extra. It feels like the honest thing to do.

But there is a catch the scammer is counting on: when a check arrives in your mailbox, it looks real. It has a bank name on it, a routing number, a signature. Your bank may even accept it and show the funds in your account. For a few days, everything looks fine.

The problem is that checks can take 5 to 10 business days — sometimes longer — to fully clear. During that window, your bank shows the money as available, but it hasn't actually arrived from the other bank yet. If the check is fake and you've already wired money back, you lose your real money and the fake check bounces.

Your bank will come after you for every cent.

The Five Most Common Versions of This Scam

Scammers run this play in many different situations. Here are the versions seniors are most likely to encounter.

1. The Online Selling Scam

You list something for sale on Facebook Marketplace, Craigslist, or a local app. A buyer contacts you, seems interested, and sends a check for significantly more than the asking price. They explain it was a mistake — they accidentally wrote the check to cover their "agent" or "movers" or "shipping company" — and ask you to deposit it and wire the difference back.

There is no buyer. There is no shipping company. There is only a fake check and someone waiting for you to wire them real money.

2. The Sweepstakes or Lottery Scam

You receive a letter, email, or phone call saying you've won a prize — sometimes a large cash amount, sometimes a car, sometimes a foreign lottery you don't remember entering. To receive your winnings, you must first pay taxes, processing fees, or customs charges. A check arrives to "help cover expenses," and you're asked to deposit it and send a portion back to claim the rest.

Real sweepstakes never require you to pay anything upfront, and legitimate winnings are never sent in the form of a check that requires a refund.

3. The Fake Employment Scam

You see a job posting for remote work — mystery shopping, package reshipment, or virtual assistant tasks. The employer sends you a check to buy supplies or equipment, with instructions to use a money transfer app to pay their "vendors" and keep a small fee for yourself.

This is called a money mule scheme. You end up processing stolen money and sending it to criminals — and you are legally responsible for your role in it, even if you didn't know the check was fake.

4. The Rental Overpayment Scam

You're renting out a room, vacation property, or storage space. A renter sends a check for several months in advance — more than the agreed amount — and asks you to forward the difference to a moving company or deposit handler.

The check bounces. The renter disappears. Your real money is gone.

5. The Gold and Gift Card Version

This is a variation you need to know about specifically. Some scammers skip the fake check entirely and go straight to the request: they claim you owe money, won a prize, or need to pay a fee — and they instruct you to buy gold coins, gold bars, or gift cards and either ship them or read the redemption codes over the phone.

No legitimate business, government agency, prize organization, or employer will ever ask you to pay in gold or gift cards. The IRS does not accept gift cards. The Social Security Administration does not ask for gold. If anyone asks you to do this, hang up.

Legitimate ways to own gold — such as a Gold IRA through a company like Augusta Precious Metals — involve you retaining full ownership of the asset, stored in a regulated depository. No one from a real company will ever call you and ask you to ship gold somewhere or hand it to a courier.

Protecting Yourself While Selling Online

Online marketplaces like Facebook Marketplace are legitimate places to buy and sell — millions of transactions happen safely every day. But they also attract scammers because the seller's information is publicly visible and the transactions are person-to-person.

A few rules that keep you safe:

Only accept cash or authorized payment apps for local sales. When selling locally, cash is safest. If you use an app, use one both parties already have — not one the buyer insists you sign up for specifically for this transaction.

Meet in person for local transactions. Many police departments and banks offer their parking lots as "safe exchange zones." Bring a friend if possible.

Never accept a check from someone you haven't met. For shipped items, use a platform with built-in payment protection. If a buyer insists on paying by check, that is a red flag.

Be especially cautious if you receive any kind of check for more than the sale price. Full stop. This pattern has one explanation.

Protect Your Financial Information When You're Online

Scammers often make first contact through email, social media, or text messages. When you're responding to listings, communicating with potential buyers, or signing up for online selling platforms, you may be sharing personal information — your email address, your location, even your bank details.

If you use public Wi-Fi in a coffee shop, library, or hotel to check messages or manage accounts, your data can be intercepted by others on the same network.

NordVPN encrypts your internet connection so that no one on the network can see your activity. It works on your phone and computer, takes about two clicks to turn on, and the first month is completely free. Think of it as a private tunnel between your device and the internet — especially useful any time you're away from your home network.
