On a money order, the purchaser signs the front, and the recipient signs the back. Your signature as the buyer goes on the line labeled “Purchaser’s Signature” (or “From,” “Signer,” or “Drawer,” depending on the issuer) on the face of the document. The person you’re paying signs the back only when they’re at the counter to cash or deposit it, in the area marked “Endorse Here.” Swapping those two locations is the single most common signing mistake, and it can void the money order or force you into a slow, paid replacement process.
Where the Purchaser Signs on the Front
Your signature line sits on the front of the money order, usually near the bottom. The exact label depends on who issued it. USPS prints “Purchaser’s Signature” clearly at the bottom of the form. Western Union and MoneyGram use slightly different wording — “From,” “Drawer,” or “Signer” — but the line lives in the same general area on the face of the document.
This signature is what makes the money order valid and payable. Under the Uniform Commercial Code, a person is not liable on a negotiable instrument unless they have signed it, which is why the purchaser’s signature is required before the payment can move.1Cornell Law School. UCC 3-401 Signature
Sign it before you leave the counter where you bought it. A partially blank money order is easier for someone else to alter or misuse if it goes missing on the way to the recipient. And do not sign the back. That area belongs to the payee, and using it yourself can cause the money order to be treated as already cashed.
The Other Fields You Fill In on the Front
Your signature isn’t the only thing that goes on the face of the money order. Complete the rest of the front fields at the same time so nothing sits blank.
Pay to the Order Of
Write the full legal name of the person or business you’re paying on the line labeled “Pay to the Order Of” (sometimes just “Pay To”). Use the name exactly as it appears on official documents. A nickname or abbreviation can cause a bank to reject the money order when the recipient tries to cash it. If you leave this line blank and the money order is lost or stolen, anyone who finds it can write in their own name and collect the funds.
Do not try to cross out or write over a mistake on the payee line. Most issuers treat any visible alteration as tampering, and banks will refuse to cash an altered money order. If you write the wrong name, contact the issuer to cancel and buy a new one.
Purchaser’s Address
Below the payee line, fill in your current mailing address in the “Purchaser’s Address” field.
Memo or Payment For Line
Many money orders include a “Payment For,” “Account Number,” or “Memo” line. If you’re paying rent, a utility, or a court fine, write the account number or invoice number here so the recipient can apply the payment correctly. It works the same way as the memo line on a personal check.
Keep the Receipt
The detachable stub is your only proof of purchase, and it carries the serial number you’d need to track, replace, or refund the money order. Hold onto it until you know the recipient has cashed or deposited the payment.
Where the Recipient Signs on the Back
The back of a money order is for the payee only. A designated area labeled “Endorse Here” or “Recipient Signature” marks where the person receiving the money signs when they’re ready to cash or deposit it.
The endorsement signature has to 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 may refuse to process it. That’s also why the ID the recipient brings to the counter needs to match the payee name on the face.
Many money orders print a warning near the endorsement area that reads “Do not sign or write below this line.” The space below that warning is reserved for bank stamps and institutional processing marks. Keep your endorsement above the line.
Wait Until You’re at the Counter to Sign the Back
An endorsed money order behaves like cash. Anyone holding a signed one can potentially claim the funds. Don’t sign the back until you’re physically at the bank, credit union, post office, or retailer where you plan to cash or deposit it.
Using a Restricted Endorsement
If you want extra protection, write “For Deposit Only” above your signature on the back and include your bank account number. This restricted endorsement 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.

Signing Mistakes That Can Void a Money Order
A few signature errors can make a money order unusable or force you through a paid replacement process.
- Signing the back as the purchaser. If you accidentally sign the endorsement area, the money order may be treated as already cashed. The recipient’s bank could reject it, and you may need to request a replacement from the issuer, which involves fees and waiting.
- Signing the back too early as the recipient. Once endorsed, a money order works like cash for whoever is holding it. Wait until you’re at the counter.
- Endorsing under a name that doesn’t match the payee line. Banks compare the endorsement to the “Pay to the Order Of” line, and a mismatch is grounds for refusal.
- Signing the space marked “Do not sign or write below this line.” That area is reserved for bank processing.
- Leaving the payee line blank on the front. A blank payee line turns the money order into something close to bearer cash if it’s lost or stolen.
If you do sign in the wrong place, don’t try to scratch it out. Visible alterations get money orders rejected. Contact the issuer, cancel the original, and buy a new one.
