If you deposit a fake money order, your bank will reverse the full amount as soon as the fraud is discovered, and you are on the hook for every dollar, even if you never suspected the instrument was counterfeit. On top of the loss, expect returned-item fees, possible overdraft charges, and a real chance your account gets closed and flagged in banking databases. Whether you also face criminal charges depends almost entirely on whether you knew.
What Your Bank Does When the Money Order Bounces
Once the issuing institution rejects the money order, your bank pulls the deposit back out of your account. If you already spent some or all of that money, your balance goes negative and you owe the difference. The Consumer Financial Protection Bureau puts it plainly: if you deposit a counterfeit money order, you will have to pay the funds back even if you already withdrew them.1Consumer Financial Protection Bureau.

Expect a returned-item fee, typically $10 to $30. If the reversal pushes your balance below zero, overdraft fees can stack on top, and each transaction that clears against the negative balance can trigger its own charge. The fees compound quickly.
Banks may also freeze or close the account outright. From their side, the account has now been involved in a fraudulent transaction, and keeping it open is a risk they don’t have to carry.
Why This Catches So Many People
The trap is a timing gap. Federal rules require your bank to make deposited funds available within a few business days, but availability is not the same as clearing. Full verification of a money order can take two weeks or longer. During that window, the money shows in your account and behaves like real money. Then the issuer rejects it.
Scammers build their entire playbook around this delay. The most common version is the overpayment scam: someone sends a money order for more than the agreed price and asks you to send back the difference by wire, gift card, or cash app. By the time the fake is discovered, you have already sent real money to someone you’ll never find. A teller telling you funds are “available” is not the same as telling you the instrument is legitimate. That distinction is where most victims lose their money.
Long-Term Damage to Your Banking
When a bank closes an account over a fraudulent deposit, it typically reports the closure to ChexSystems, a consumer reporting agency that most major banks check before approving new accounts. A fraud flag there can get you denied elsewhere, and the record can stay on file for up to five years.
Losing access to a checking account pushes people toward check-cashing services and prepaid debit cards, which charge for routine transactions banks handle for free. Most of those alternatives also don’t report to credit bureaus, so the usual path to building credit through a banking relationship narrows. A single bad deposit can shape your finances for years.
Could You Be Charged With a Crime?
The legal exposure turns on whether 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 broader 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 instruments, prosecutors can sometimes charge under this law as well, and it 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.
Intent is the key. 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 A genuine victim is far less likely to be convicted, but the investigation itself is stressful. Law enforcement may examine your communications, your banking patterns, and your relationship with whoever handed you the money order before concluding you were the one being scammed.
Civil liability is also possible. If you passed money from the fake deposit along to someone else, that person or your bank may seek repayment through a civil claim.
What to Do Right Now
Speed matters. The sooner you act, the better your standing with both the bank and any investigator who eventually looks at the file.
- Call your bank and tell them you believe the money order is fraudulent. Hand over every detail you have: the instrument itself, when you received it, and who gave it to you. Voluntary disclosure reads very differently from the bank discovering the fraud on its own.
- Preserve everything. Save every text, email, social media message, and receipt tied to the transaction, and screenshot anything the sender might delete. This is what investigators need to trace the scammer.
- File a report with the Federal Trade Commission at ReportFraud.ftc.gov.5Federal Trade Commission. ReportFraud.ftc.gov
- If the money order was a U.S. Postal Service instrument, report it to the U.S. Postal Inspection Service, which investigates mail-related fraud.6United States Postal Inspection Service. Report – Mail Fraud
- If you shared personal information with the sender, such as your address, account number, or Social Security number, contact the three major credit bureaus, request fraud alerts, and consider a credit freeze. Money order scams are often the opening move in a larger identity theft scheme.7USAGov. Identity Theft
Verify Before You Deposit
The safest habit is to verify a money order directly with the issuer before it ever hits your account. The U.S. Postal Service runs a Money Order Verification System at 866-459-7822.8United States Postal Service. Verifying U.S. Postal Service Money Orders Western Union has an inquiry line at 720-945-9361.9Western Union. Contact Customer Service in the United States MoneyGram customers can call the number printed on the money order.
The single biggest red flag is a money order for more than what someone owes you, paired with a request to send back the difference through a wire transfer, gift card, or cash app. Legitimate buyers do not overpay and ask for refunds through untraceable channels. If the circumstances feel unusual, require a different form of payment. Trust that instinct before you deposit, not after.
