If you made a mistake filling out a money order, do not cross anything out, erase, or use correction fluid — any visible alteration will cause banks and retailers to reject it. The fix for a money order mistake is to take the spoiled document back to the issuer and request a replacement. At USPS, that exchange is free when you still have the money order and your purchase receipt. Western Union and MoneyGram charge fees that depend on the face value.
Why You Can’t Just Correct It
Money orders are built to resist tampering. USPS money orders carry embedded security threads, a Pony Express rider watermark, and background patterns visible only against light.1USPIS.

A pen correction or a dab of white-out looks identical to fraud under those checks, and the retailer or bank receiving the document will refuse it. Treat the money order as dead and move on to a replacement.
Free USPS Replacement for a Spoiled Money Order

Replacement at Western Union and MoneyGram
Private issuers do not offer a universally free exchange. You pay a refund or replacement fee, and the fee depends on the money order’s face value.
Western Union charges a tiered refund processing fee: nothing for money orders worth $5 or less, $5 for money orders above $5 but under $100, and $15 for money orders with a face value of $100 or more.4Western Union.

What to Bring to the Counter
Three things make any replacement go smoothly regardless of issuer: the original money order (even filled out wrong), your purchase receipt, and a government-issued photo ID. The receipt matters most, because it carries the serial number, purchase date, and issuing location the clerk needs to match the transaction.

If You Don’t Have the Receipt
Losing the receipt makes the fix slower and more expensive, because the serial number printed on it is what ties you to the money order.
At USPS, the clerk is instructed to verify the serial number, date, and amount from the receipt before processing a replacement, so without it you will need to supply as much detail as possible about the purchase location, date, and amount, and let the post office try to track the transaction.9USPS.

Frequently Asked Questions About Purchasing a Money Order
USPS postal money orders do not carry dormancy fees. Any uncashed money order from any issuer can eventually be turned over to a state’s unclaimed property division, with the dormancy period before escheatment typically ranging from three to seven years. If you discover an old money order with a mistake on it, deal with the replacement before fees or escheatment shrink the balance.
What This Doesn’t Cover
The replacement process above is for a money order you still physically hold. If the money order was lost, stolen, or has already been cashed, that is a different procedure involving a formal inquiry, longer timelines, and in some cases a notarized forgery affidavit. Western Union, for instance, sets an 11-month deadline from the date of payment for filing forgery claims.12Western Union. Purchasers Affidavit Forgery If that is your situation, contact the issuer directly and, where fraud is suspected, file a police report before the claims window closes.
