You can cancel a money order in most cases, but only if the recipient hasn’t cashed it yet, and the steps, fee, and wait time depend entirely on who issued it. USPS is the exception: it doesn’t offer stop payments at all, and will only replace a postal money order that’s been lost or stolen. Fees run roughly $5 to $21, and investigations take anywhere from about two weeks to two months.
The One Condition That Decides Everything
A money order can only be canceled, refunded, or replaced before someone cashes it. Once the payee deposits or cashes it, the transaction is final and no issuer will reverse it on your behalf.
So check the status before you file anything. Most issuers let you look up a money order using the serial number on your purchase receipt. USPS lets you check at any Post Office counter or through its online Money Orders Application. Western Union lets you verify status online before you submit a refund request. MoneyGram shows status information during the refund process on its website. Every day you wait is another day the money order could be cashed and put cancellation out of reach.

Western Union Money Orders
Western Union accepts refund requests for uncashed money orders through an online form. The system lets you verify whether the money order has already been cashed before you submit. You’ll need to upload a scan or photo of your purchase receipt (the portion with the barcode) or the money order itself as proof of purchase.4Western Union. Money Order Refund Request

- $5 or less: no fee
- Above $5 but under $100: $5 fee
- $100 or more: $15 fee
If the money order hasn’t been cashed, Western Union typically processes the refund within six to eight weeks.5Western Union. Money Order Research Request If it was already cashed, you get a photocopy of the front and back instead of money back.4Western Union. Money Order Refund Request

MoneyGram Money Order Frequently Asked Questions
Bank-Issued Money Orders
If you bought the money order from a bank or credit union, contact that institution directly. Fees and timelines depend on the bank’s own policies. Some banks treat a money order cancellation like a check stop-payment request, which can run $25 to $30. Certain premium checking accounts waive stop-payment fees. Call or visit the branch where you made the purchase to find out what’s required.
What You’ll Need to File
Whichever issuer you’re dealing with, the purchase receipt is the single most important piece of documentation. That small paper slip contains the serial number, the dollar amount, and the location identifier (a Post Office number or store code). Without the serial number, most issuers can’t locate your transaction.
A complete claim usually requires:
- The serial number, printed on both the money order and the receipt
- The exact dollar amount, which must match the issuer’s records
- The purchase date
- The Post Office or store where you bought it
- Your name and address, so the refund or replacement can reach you
- The payee name — the person or business you made it payable to
Gather all of it before you contact the issuer. Incomplete requests are the most common reason for delays. Also budget for the processing fee in advance and confirm what payment methods the issuer accepts, since some require a separate check or money order rather than cash or card. Processing fees are generally non-refundable even if it turns out the money order was already cashed.
If the Money Order Was Already Cashed
An investigation that finds the money order was cashed doesn’t produce a refund. The issuer will typically send you a photocopy or scanned image of the front and back, including endorsement signatures.3USPS. PS Form 6401 – Money Order Inquiry
That image matters because it shows who endorsed and cashed it. If someone other than your intended payee cashed the money order — meaning the endorsement was forged or unauthorized — you may still have recourse. For USPS postal money orders, the Postmaster General has the right to demand a refund from the bank that accepted the money order if the endorsement was forged or unauthorized.8About USPS Home. DMM Revision – Money Order Reclamation You can also file a police report and, depending on the circumstances, pursue the matter in small claims court against the person who cashed it without authorization.
If the Money Order Was Stolen
If yours was stolen rather than simply misplaced, file a police report right away. Several issuers require or recommend a copy as part of the refund process. If you mailed the money order through USPS and believe it was stolen in transit, contact the U.S. Postal Inspection Service at 877-876-2455 and ask USPS to intercept the package.9Federal Trade Commission. ReportFraud.ftc.gov – FAQ
You can also report the theft at ReportFraud.ftc.gov. The FTC can’t recover your money, but the report creates a record that supports law enforcement action and helps document your loss for the issuer’s investigation.9Federal Trade Commission. ReportFraud.ftc.gov – FAQ
Old Money Orders Sitting Uncashed
Money orders generally don’t expire, but their full value isn’t preserved indefinitely either. Depending on the issuer, a monthly or periodic service charge may start eating into the face value after one to three years of inactivity.10Western Union. Money Orders – Purchase and Cash at a Western Union Near You Every state also has unclaimed property laws that require issuers to turn over uncashed money orders to the state after a set number of years, typically three to seven. Once the funds are escheated, you’d file an unclaimed property claim with that state’s treasurer or controller rather than going back to the issuer. If you have an old money order in a drawer, cashing or refunding it sooner avoids both the dormancy deductions and the unclaimed property route.
