If you deposit a fake money order, your bank will reverse the entire amount from your account once the fraud is discovered, and you are on the hook for the loss even if you had no idea the instrument was counterfeit. You may also face returned-item fees, overdraft charges, account closure, a negative mark in banking databases, and, depending on what you knew, a criminal investigation. The financial damage almost always exceeds the face value of the money order itself.
The Bank Claws Back the Money
When a bank identifies a deposited money order as fraudulent, it reverses the full deposit. If you already spent some or all of those funds, your balance goes negative and you owe the bank the difference. The Consumer Financial Protection Bureau is direct about this: if you deposit a counterfeit money order, you have to pay the funds back even if you already withdrew them.1Consumer Financial Protection Bureau.

Expect a returned-item fee on top of the reversal, typically $10 to $30. If the clawback pushes your balance below zero, overdraft fees can stack on top. These charges compound quickly when you made multiple purchases against the deposited amount, because each resulting transaction can trigger its own fee.
Why the Money Looked Real at First
The reason so many people end up in this situation is a timing gap most depositors do not know about. Federal rules require your bank to make deposited funds available within a few business days, but availability is not verification. Full clearing can take two weeks or longer. During that window, the money shows up in your account and behaves like real money. Then the issuing institution rejects the item, and the deposit unwinds.
Scammers build their entire playbook around this gap. The classic setup is the overpayment scam: someone sends a money order for more than an agreed price and asks you to wire the difference back, often as a wire transfer, gift card, or cash app payment. By the time the bank flags the money order as fake, you have already sent real money to the scammer, and that money is gone. A teller confirming that funds are “available” is not confirming the instrument is legitimate.
Account Closure and ChexSystems
Banks often freeze or close accounts involved in fraudulent deposits. From the bank’s point of view, your account has been used in a fraud, and keeping it open creates ongoing risk.
A closure of this kind typically gets reported to ChexSystems, a consumer reporting agency that tracks banking history. Most major banks check ChexSystems before opening new accounts, and a fraud-related flag can lead to denials. These records stay on file for up to five years.
Being shut out of traditional banking pushes people toward check-cashing stores and prepaid debit cards, which charge fees on routine transactions a checking account handles for free. Most of those alternatives also do not report to credit bureaus, so you lose a channel for building credit at the same time. A single bad deposit can ripple out for years.
Could You Be Charged With a Crime?
Your criminal exposure turns almost entirely on what you knew. If you knowingly deposited a forged postal money order, the most directly applicable federal law is 18 U.S.C. § 500, which covers forging, counterfeiting, or passing a fraudulent postal money order with intent to defraud. The penalty is a fine and up to five years in federal prison.2Office of the Law Revision Counsel. 18 USC 500 – Money Orders
A separate statute, 18 U.S.C. § 472, covers passing counterfeit obligations or securities of the United States with intent to defraud. Because postal money orders are government-issued financial instruments, prosecutors can sometimes charge under this broader law as well, which carries up to twenty years in prison.3Office of the Law Revision Counsel. 18 USC 472 – Uttering Counterfeit Obligations or Securities For fake money orders from private issuers like Western Union or MoneyGram, federal mail fraud or bank fraud charges may apply, along with state forgery laws.
The word that matters in these statutes is “intent.” Federal jury instructions for counterfeiting charges require prosecutors to prove three things: that you passed a forged instrument, that you knew it was forged, and that you acted with intent to defraud.4Ninth Circuit District and Bankruptcy Courts. Manual of Model Criminal Jury Instructions – 13.2 Passing or Attempting to Pass Counterfeit Obligations If you genuinely did not know the money order was counterfeit, a conviction is far less likely. Even so, the investigation itself can be stressful. Law enforcement may examine your communications, your banking patterns, and your relationship with whoever gave you the money order before concluding you were a victim rather than a participant.
Civil liability is also possible even without criminal charges. If you passed along money from the fake deposit to a third party, that person or your bank may pursue repayment through a civil claim.
What to Do Right Now
Speed matters. The sooner you act, the better your position with both the bank and any investigator.
- Contact your bank immediately and tell them you believe the money order is fraudulent. Turn over the money order and share every detail: when you received it, how, and who sent it. Voluntary disclosure looks very different from the bank discovering the fraud on its own.
- Preserve every piece of evidence. Save texts, emails, social media messages, listings, and receipts tied to the transaction. Screenshot anything the sender might delete. This documentation is what investigators use to trace the scammer.
- File a report with the Federal Trade Commission at ReportFraud.ftc.gov. These reports feed into pattern tracking and case-building.5Federal Trade Commission. ReportFraud.ftc.gov
- If the item was a U.S. Postal Service money order, report it to the U.S. Postal Inspection Service, which investigates mail-related fraud.6United States Postal Inspection Service. Report – Mail Fraud
- Protect your identity if you shared any personal information with the sender. Contact the three major credit bureaus, request fraud alerts, and consider a credit freeze. Money order scams are sometimes the opening move in a larger identity theft scheme.7USAGov. Identity Theft
Avoiding It Next Time
Before depositing any money order, inspect it. Genuine USPS money orders include a watermark of Benjamin Franklin visible when held to light and a dark security thread through the paper. Western Union and MoneyGram money orders use their own features, including heat-sensitive ink and microprinting. Fuzzy printing, off colors, or paper that feels like standard copy stock are all warning signs.
The single biggest red flag is an overpayment. If someone sends a money order for more than they owe and asks you to return the difference through a wire transfer, gift card, or cash app, it is almost certainly a scam. Legitimate buyers do not overpay and then ask for refunds through untraceable channels. When in doubt, verify the money order directly with the issuer before you deposit, and if the circumstances still feel off, ask for a different form of payment.
