On a money order, the purchaser signs the front and the recipient signs the back. If you bought it, your signature belongs on the line labeled “Purchaser’s Signature” (some forms say “From,” “Drawer,” or “Signer”) near the bottom of the front. If you received it, your signature belongs in the endorsement area on the back, and only when you’re standing at the bank, credit union, or store where you plan to cash or deposit it. Swapping those two locations is one of the most common mistakes people make, and it can void the money order or force you into a slow, paid replacement process.
Signing the Front as the Purchaser
Your signature line sits on the front, usually near the bottom. The exact label depends on who issued the money order. USPS prints “Purchaser’s Signature” clearly at the bottom. Western Union and MoneyGram forms use wording like “From,” “Drawer,” or “Signer,” but the line sits in the same general area.
Sign it before you leave the counter where you bought it. Under the Uniform Commercial Code, a person is not liable on a negotiable instrument unless they signed it, which is why this signature is what actually makes the money order valid and payable.1Cornell Law School. UCC 3-401 Signature An unsigned money order is an incomplete document.
Do not sign the back. That side is reserved for the person receiving the payment.
Signing the Back as the Recipient
If someone paid you with a money order, your signature goes on the back, in the space marked “Endorse Here” or “Recipient Signature.” Your endorsement must match the name written on the “Pay to the Order Of” line on the front. If the names don’t match, a bank or check-cashing location can refuse to process it.
Wait until you’re at the counter to sign. An endorsed money order behaves like cash: whoever holds it can potentially claim the funds, so signing at home and then walking or mailing it in exposes you to loss or theft. Many money orders also print a warning near the endorsement area that reads “Do not sign or write below this line.” The space below that line is reserved for bank stamps and processing marks, not your signature.
For Deposit Only
If you plan to deposit the money order rather than cash it, you can add a restricted endorsement. Write “For Deposit Only” above your signature on the back and include your bank account number. That instruction means the money order can only be deposited into that specific account and cannot be cashed over the counter by anyone, including you.2Consumer Financial Protection Bureau. What Does It Mean for a Check to Be Indorsed for Deposit Only It’s a useful safeguard if you’re mailing the money order to your bank instead of visiting in person.
What Happens If You Sign in the Wrong Place
Signing the back as the purchaser is the mistake with the worst consequences. Because the back is the endorsement side, a signature there can make the money order look as though it has already been cashed or is being negotiated to someone else. The recipient’s bank can reject it, and you’ll likely have to request a replacement from the issuer, which involves fees and waiting.
The mirror problem, a recipient who signs the front, doesn’t validate anything. The payee line and the purchaser’s signature line are for the buyer only. A stray recipient signature on the front can look like an alteration, and visible alterations are treated as tampering by most issuers and banks.
If you notice the mistake before the money order has moved, don’t try to cross out or write over what you signed. Contact the issuer, cancel the money order, and buy a new one.
The Other Front Fields Your Signature Depends On
Your signature only completes a money order that’s otherwise filled in correctly. Fill in the rest of the front at the counter, before you sign, so no one else can alter a partially blank document.
On the “Pay to the Order Of” line (sometimes just “Pay To”), write the full legal name of the person or business receiving the payment. Use the name as it appears on official documents. A nickname or abbreviation can cause a bank to reject the money order when the payee tries to cash it. If you leave this line blank and the money order is lost or stolen, whoever finds it can write in their own name and collect the funds.
Below the payee line, fill in your current mailing address in the “Purchaser’s Address” field. If the form has a “Payment For,” “Account Number,” or “Memo” line and you’re paying a bill, write the relevant account or invoice number there so the recipient can credit the payment correctly. Treat it the way you’d treat the memo line on a personal check.
Once those fields are complete, sign the purchaser’s line on the front. That’s the last step before you walk away.
Keep the Receipt
The detachable stub or receipt from your money order is your only proof of purchase, and it carries the serial number. That number is what you need if anything goes wrong: to track the money order, to request a replacement if it’s lost or stolen, or to cancel one that was signed incorrectly and buy a fresh one. Hold onto it until you’ve confirmed the recipient has cashed or deposited the payment. Without the receipt, recovering a money order becomes significantly harder and may not be possible at all.
Where to Sign When You’re Ready to Cash It
When you take a money order somewhere to cash it, bring a valid government-issued photo ID, and make sure the name on your ID matches the payee name on the front. Endorse the back only once you’re at the counter and ready to complete the transaction. Banks, credit unions, post offices, and many retail stores that offer check-cashing services will process money orders. You can typically avoid an extra fee by cashing a money order at the same institution that issued it, and banks and credit unions often waive cashing fees for their own account holders.
