Don’t do it. Crossing out a mistake on a money order will almost always get it rejected, because banks and check cashers treat any visible correction as a sign of fraud. The right move is to keep the spoiled money order and its receipt, bring both back to the issuer, and ask for a replacement. With USPS, that replacement is free.
Why a Correction Kills the Money Order
A money order is a negotiable instrument, which means it works like a guaranteed check backed by prepaid funds. Under the Uniform Commercial Code, an “alteration” is any unauthorized change that modifies someone’s obligation, including crossing out a name and writing a new one. A fraudulent alteration discharges the original obligation entirely and the document loses its legal force.1Legal Information Institute. UCC 3-407 Alteration A bank or store that cashes an obviously altered money order risks absorbing the loss, so tellers are trained to turn them away.
The paper itself is built to expose tampering. A USPS money order carries a Benjamin Franklin watermark visible when held to light, a security thread running top to bottom with “USPS” repeated along it, and ink that discolors around the dollar amounts if someone tries to change them.2USPS. Verifying U.S. Postal Service Money Orders Correction fluid, an eraser, or a heavy pen stroke can set off those features. Once the tampering is visible, no one is cashing it.
That is true even when the mistake is innocent, like a misspelled payee name or a wrong middle initial. The teller cannot tell your honest slip from someone else’s forgery, and they are not supposed to try.

The replacement is free, so this is usually cheaper than buying another one. A new USPS domestic money order costs $2.55 for amounts up to $500 and $3.60 for amounts between $500.01 and $1,000, which is the maximum for a single USPS money order.5USPS.

Western Union and MoneyGram Money Orders
If your money order was issued by Western Union, submit a refund request using the company’s Money Order Request Form. Western Union deducts a processing fee from the refund amount if the money order has not been cashed:
- Face value of $5 or less: no fee
- $5.01 to $99.99: $5 fee
- $100 or more: $15 fee
Without proof of purchase, Western Union runs a search and notifies you of the results in two to four weeks.6Western Union. Money Order Request Form
MoneyGram also processes refunds on money orders that have not been cashed, but it does not publish its fee schedule. You have to start a refund request to see the amount. MoneyGram charges an $18 processing fee if you need a photocopy of a cashed money order for your records.7MoneyGram. MoneyGram Money Order Frequently Asked Questions
If You Already Sent It or Can’t Find It
If you no longer have the physical money order, you are no longer in spoiled-replacement territory. You are filing a lost or stolen claim, and that costs money and takes time. For USPS, the inquiry fee is $21.8U.S. Postal Service. Sending Money Orders – Replacing Lost, Stolen, or Damaged Money Orders The fee covers the investigation into whether the money order has been cashed and, if it has not, the issuance of a replacement.
Bring your original purchase receipt to any Post Office and complete PS Form 6401 with the serial number, dollar amount, purchase date, and Post Office number, all of which appear on the receipt. USPS will not issue a replacement until at least 60 days after the money order’s original purchase date, and only if the money order has not been cashed. If it has already been cashed, you get a copy of the paid money order instead.4USPS. PS Form 6401 – Money Order Inquiry
So if you crossed something out and already mailed the money order hoping the recipient could still cash it, you are better off warning them not to try, retrieving it if possible, and bringing it back for the free replacement rather than starting a paid lost-or-stolen claim.
Fill It Out Right the Next Time
A few habits keep you out of the replacement line:
- Fill in the payee’s name first, before signing or detaching the receipt, so you can void the money order right away if something goes wrong.
- Match the payee name to their ID exactly. A misspelled name can keep them from cashing it.
- Use black ink. It stays legible and does not smudge, and PS Form 6401 requires it if you ever need to file an inquiry.4USPS. PS Form 6401 – Money Order Inquiry
- Keep the receipt separate from the money order. It is your proof of purchase and carries the serial number you need for any future inquiry. Do not staple it to what you send.
- Mind the cap. A single USPS money order cannot exceed $1,000.5USPS. Price List – Notice 123
- Fill it out at the counter. If you make a mistake, the clerk is right there to help you spoil and replace it on the spot.
