Fake Check and Overpayment Scams: Why Available Funds Do Not Prove a Check Is Good
A fake check scam starts when someone you do not know asks you to deposit a check and then tells you to send some of the money back to them or to another person. By law, banks have to make deposited funds available quickly, so the money can show up in your account before anyone finds out the check is fake. That can take weeks, and by then the scammer has any money you sent.

What the official consumer pages say
The Federal Trade Commission page How To Spot, Avoid, and Report Fake Check Scams describes the basic pattern in plain terms: a stranger "asks you to deposit a check," and then "They tell you to send some of the money back to them or to another person." The same agency's general page on avoiding scams describes the same move: "Some will send you a check (that will later turn out to be fake), then tell you to deposit it and send them money."
Common versions of the story
The story changes, but the request stays the same. In a fake job offer, scammers "pretend to hire you as a mystery shopper." In the overpayment version, people buying something from you online "send a check for too much, and ask you to refund the balance." The advice for sellers is short: do not "accept a check for more than the selling price."
Why money in your account does not prove the check is good
The fake check page explains that "fake checks generally look just like real checks, even to bank employees." They are "often printed with the names and addresses of legitimate financial institutions," and they "may even be real checks written on bank accounts that belong to someone whose identity has been stolen."
Timing is the other half of the answer. The page states: "By law, banks have to make deposited funds available quickly. Even if you see the funds in your account, that doesn't mean it's a good check." It adds that "Fake checks can take weeks to be discovered and untangled," and that by that time "the scammer has any money you sent, and you're stuck paying the money back to the bank." So seeing the money as available in your account does not settle whether the check was real.
Signs to watch for
- Someone you do not know asks you to deposit a check and pass some of the money on.
- A buyer sends a check for more than the selling price and asks you to refund the balance.
- You are told to pass the money on by gift card, money order, cryptocurrency or wire transfer. The page is direct: "Never use money from a check to send gift cards, money orders, cryptocurrency, or to wire money to anyone who asks you to."
- You are rushed. The general page warns: "Scammers want you to act before you have time to think."
If you already sent money
The fake check page lists steps that depend on how you paid, and most of them ask you to act quickly:
- Gift card: "tell the company that issued the card right away."
- Wire transfer: "call the wire transfer company immediately to report the fraud and file a complaint."
- Cryptocurrency: "contact the company you used to send the money and tell them it was a fraudulent transaction."
- Money order: contact the company that issued it right away to see if you can stop payment, and if you sent it by U.S. mail, contact the U.S. Postal Inspection Service at 877-876-2455.
The page is also frank about the odds. Paying a scammer by gift card, cryptocurrency or wire transfer is, in its words, "like you've given them cash," and "It's almost impossible to get it back." For a wire transfer, it says a reversal is "unlikely to happen, but it's important to ask."
Where to report
If you were targeted, the fake check page names the Federal Trade Commission, the U.S. Postal Inspection Service and your state Attorney General as places to report. The general page says: "If you were scammed or think you saw a scam, tell the FTC at ReportFraud.ftc.gov."
What these pages do not cover
The cited pages do not explain how a particular bank handles a specific deposit, how long it takes in a given case to find out that a check is fake, or whether any money can be recovered in a particular situation. Those answers depend on the situation.
