How to Spot a Fake Check Before You Deposit It

Key takeaways

If a stranger sends you a check and asks you to send part of the money back, that is a fake check scam, whatever story comes with it.
Banks must make deposited funds available quickly, so money can appear in your account long before the check bounces and you owe the bank.
Never accept a check for more than the amount you are owed, and never wire money back to someone who claims to have overpaid you.
Bank staff spot fraudulent checks regularly, so it makes sense to ask your bank about an unexpected check before depositing it.
If you already deposited a suspicious check, contact your bank right away and report the scam to the FTC at ReportFraud.ftc.gov.

A check arrives with a friendly note: you have been hired, you have won a prize, or a buyer sent a little extra by mistake. All you are asked to do is deposit it and return the difference. That request is the signature of a fake check scam, and here is how it works, what to check before depositing, and what to do if money has already moved.

What a Fake Check Scam Looks Like

The setup follows a formula. Someone you have never met persuades you to deposit a check, usually for more than you are owed and sometimes for several thousand dollars, then instructs you to return part of the proceeds. The story shifts: covering taxes or fees on a prize, buying supplies for a new job, or refunding an accidental overpayment. Whatever the details, a stranger who sends a check and wants money back is running a scam.

Counterfeits can take several forms: business or personal checks, cashier’s checks, money orders or electronically delivered checks, the Federal Trade Commission (FTC) notes. A cashier’s check is drawn on a bank’s own funds, so recipients often treat it as guaranteed payment. A money order is a prepaid payment instrument bought with cash. Counterfeits of both are common.

Why Your Bank May Release the Money First

Federal rules push banks to release deposit money quickly, and scammers count on that speed. The American Bankers Association (ABA), an industry group, cautions that being able to withdraw money does not mean the check is good, even for cashier’s checks and money orders. Modern printing technology lets criminals produce counterfeits in minutes. Fake checks often carry the names and addresses of real financial institutions, and some are genuine checks written on accounts belonging to people whose identities were stolen. They can look real enough to fool bank employees.

The scammer wants your money before the bank finishes processing the check. When the problem surfaces, the check bounces, you owe the bank the funds it released, and anything you already sent is generally gone.

Be aware: Money showing in your account is not proof a check is real. Banks release funds before checks finish clearing, and you will have to repay the bank if the check turns out to be counterfeit.

Step 1: Question the Check and Its Amount

Start with the simplest questions. Did you expect this check? If it comes from a stranger, follows an out-of-the-blue email, text or social media message, or relates to a prize you never entered, treat it as suspicious until you can verify it. Then compare the amount with what you are owed: the FTC advises never accepting a check worth more than your selling price. A legitimate buyer has no reason to overpay, and a legitimate employer does not need you to front money from your own account.

Step 2: Look for a Request to Send Money Back

This is the clearest sign. The return request can arrive as a wire transfer (an electronic transfer through a money service), a payment app payment, a gift card with its PIN shared, cryptocurrency, cash, a prepaid card or a personal check. The ABA’s rule of thumb: nobody paying you has a good reason to ask for money back or to send more than the exact amount owed.

Step 3: Resist Pressure to Act Now

Scammers rush you because time exposes them. The FTC’s advice for sellers applies broadly: if an offer is good today, it should still be good once the check clears.

Step 4: Verify the Check and the Sender

If you accept payment by check, the FTC suggests asking for one drawn on a local bank or a bank with a local branch, since you can visit to confirm it. Verify who you are dealing with before sending anyone money. If a buyer proposes an escrow service (a neutral third party that holds payment until both sides deliver) or a payment service you have not heard of, research its terms and reliability first, and skip it if you feel unsure.

Step 5: Ask Your Bank Before You Deposit

Bank staff see fraudulent checks regularly and can spot problems you cannot. The ABA recommends explaining the source of the check, why it was sent to you, and whether anyone has asked you to wire money back. If something does not add up, do not deposit it. Report it instead.

Common Versions: Overpayments, Mystery Shopping and Prize Winnings

Knowing the standard scripts makes them easier to catch.

Overpayment scams. You sell an item online. The buyer’s check is for too much, they invent a reason for the extra, and ask you to wire back the difference. When the check bounces, you owe the bank the full amount.
Mystery shopping. The first assignment is to review a store that sells gift cards, money orders or wire transfer services. You deposit a check and wire part of it on, and the money plus the employer vanish.
Job versions. Fake personal assistant roles ask you to buy gift cards and send the PINs to your boss. Car wrap offers tell you to deposit a check and pay installers who do not exist.
Prizes and lotteries. A sweepstakes check arrives with a request to cover taxes, shipping or processing fees. Legitimate sweepstakes do not charge winners, and playing a foreign lottery by mail or telephone is against the law in the United States.

Many of these overlap with imposter scams, in which the sender poses as a real employer, agency or company.

What to Do if You Already Deposited a Suspicious Check

Stop sending money, whatever the sender says.
Contact your bank immediately and explain what happened, including any request to send money back. Staff may be able to flag the deposit before losses grow.
Leave the balance alone. Do not spend money from the check.
Expect to repay the bank if the check is counterfeit.
If you shared account details or other personal information, monitor your accounts and review your credit reports. Our guide to checking your credit report and disputing errors explains how.
Consider a police report. The FDIC, the federal agency that insures bank deposits, advises fraud victims to report incidents to local law enforcement or the FBI.

Where and How to Report a Fake Check

Reporting helps twice: it alerts your bank, and it feeds the data investigators use to build cases. File a report with the FTC at ReportFraud.ftc.gov, where reports are visible to other law enforcement agencies. The ABA also suggests reporting suspected fake check fraud to the Better Business Bureau’s Scam Tracker.

If the scam used a government agency’s name, pay attention. The FDIC has warned about impostors whose messages look official, sometimes including a cashier’s check to deposit and wire back in part. The FDIC does not send unsolicited requests for money or sensitive personal information, and no government agency will demand payment by gift card, wire transfer or digital currency. For possible FDIC-related fraud, call 1-877-ASK-FDIC (1-877-275-3342), Monday to Friday, 8 a.m. to 8 p.m. Eastern.

One more step costs nothing: talk to someone you trust before acting on a check from a stranger. Saying the story out loud often makes the cracks visible. For the full reporting process, see how to report a scam in the United States, step by step.

Common questions

Q: Can a check clear and still turn out to be fake?

A: Yes. Federal law requires banks to make deposited funds available quickly, but that does not mean the check is good. A counterfeit check can bounce days later, leaving you to repay the bank any money you withdrew or sent.

Q: Is a cashier’s check always safe to accept?

A: No. Counterfeit cashier’s checks and money orders are common in fake check scams, and they can look convincing even to bank employees. The appearance of a check proves nothing about whether it is genuine.

Q: Why would someone send me a check I never asked for?

A: An unexpected check from a stranger is often the opening move of a scam, paired with a story about a prize, a job or an accidental overpayment. Ask your bank before depositing any check you were not expecting.

Q: What should I do if I already sent money to a check scammer?

A: Stop sending money, contact your bank immediately and explain what happened. Then report the scam to the FTC at ReportFraud.ftc.gov so investigators can use the information in their cases.
