Fill in the payee name first, then the amount, then sign it
A money order has five main blanks: who it goes to (the payee), how much it is for, who it is from (you), the date, and your signature. You fill these in the same order you would on a check. The payee line is where you write the name of the person or business that will cash it. The amount goes in two places — once in numbers and once written out in words. Your name and address go in the "from" section. You sign it only after the payee name is filled in, because a blank money order can be cashed by anyone.
The order matters because some fields lock in the value once you write them. If you make a mistake on the payee name or amount, most issuers will not let you cross it out and rewrite it — you will need to buy a new money order. Pen is required; pencil can be erased and altered. Write clearly and stay inside the lines, because money order machines at banks and post offices read these fields electronically.
Key Takeaways
- Write the payee name in the "Pay to the Order of" line before you write the amount, because you cannot change it afterward.
- Enter the dollar amount twice — once as numbers (like $50.00) and once as words (like "Fifty Dollars") — and both must match exactly.
- Use pen only, write clearly and within the printed lines, and do not cross out or erase anything on the money order itself.
- Sign the money order only after the payee name is complete, because an unsigned or blank money order can be cashed by anyone who has it.
- Keep your receipt stub until the money order is cashed, because it is your proof of payment if there is a dispute.
Where each field goes and what to write
The "Pay to the Order of" line is usually at the top left of the money order. Write the full name of the person or business that will receive the money. If it is a business, use the exact legal name — "Joe's Plumbing" rather than "Joe" or "Joes Plumbing." If you are unsure of the exact name, ask the person or business before you buy the money order, because you cannot change it once it is written.
The amount field appears twice on most money orders. The first is a box or line marked with a dollar sign, where you write the numbers: $50.00, $125.50, and so on. The second is a longer line where you write out the amount in words: "Fifty Dollars and 00/100" or "One Hundred Twenty-Five Dollars and 50/100." The cents are written as a fraction over 100. Both fields must show the same amount. If they do not match, the money order is invalid and the issuer will not cash it.
Your name and address go in the "From" section, usually at the bottom left. This is who the money order came from — you. Some money orders also have a "Memo" line where you can write a note, like an invoice number or what the payment is for. This is optional and does not affect whether the money order works.
The signature line and when to sign
The signature line is usually at the bottom right. Do not sign until the payee name and amount are completely filled in. A money order with a blank payee line or no amount is as good as cash to anyone who holds it — they can fill in their own name and cash it. Some people buy a money order and sign it right away, then hand it to someone else to fill in the payee name. This is a risk because the person could write in their own name instead.
Sign in the same way you sign checks or other documents. Your signature does not have to match any ID perfectly, but it should be recognizable as your signature. Printing your name does not count as a signature. If you cannot write, ask the issuer what to do — some will allow a mark or thumbprint, though this is rare.
Common mistakes that make a money order invalid
Writing the amount in numbers but not in words, or writing different amounts in each place, is the most common error. A money order for "$50" in the number box but "Thirty Dollars" in the words box will be rejected. The issuer cannot guess which amount you meant. If you make this mistake before you leave the counter, tell the seller right away and ask for a replacement.
Crossing out or erasing anything on the money order makes it invalid. The machines that read money orders at banks and post offices cannot process altered documents, and tellers will refuse to cash them by hand because alterations are a sign of fraud. If you write something wrong, do not try to fix it — buy a new money order instead.
Leaving the payee line blank or writing a name that is too vague is another problem. "Cash" is not a valid payee name on most money orders issued today. If you write "John" but the recipient's legal name is "John Michael Smith," some banks will reject it because the names do not match exactly. Ask the recipient for their full legal name before you fill it in.
What to do with your receipt
When you buy a money order, you receive a receipt stub that stays with you. This stub shows the money order number, the amount, the payee name, the date, and the fee you paid. Keep this receipt until the money order has been cashed and the recipient confirms they received the money. If the money order is lost, stolen, or never reaches the recipient, you will need the receipt number to file a claim with the issuer.
The receipt is your proof that you sent the money. If a dispute arises — the recipient says they never got it, or you need to prove you paid a bill — the receipt is what you show. Most issuers will replace a lost or stolen money order if you have the receipt number and can show you paid for it. Without the receipt, replacing it is much harder and may not be possible.
Money orders from different issuers have slightly different layouts
The U.S. Postal Service, Western Union, MoneyGram, and banks all issue money orders, and the blank fields are in slightly different places on each one. The payee line might be at the top on one issuer and in the middle on another. Before you start writing, look at where each line is labeled and read the instructions printed on the money order itself. Most money orders have small text that says "Pay to the Order of" or "Payee" to mark where the name goes.
Some money orders have a maximum amount — the Postal Service caps theirs at $1,000, for example — so if you need to send more than that, you will need to buy multiple money orders. A few issuers also require you to write your phone number or ID number in a specific box. Read the front and back of the money order before you buy it, so you know what information you will need to provide.
Frequently Asked Questions
What happens if I write the wrong payee name?
You cannot change it. Money orders cannot be altered once they are written. You will need to contact the issuer and ask for a refund or replacement, which may take several days and may include a fee. The safest approach is to confirm the payee name with the recipient before you buy the money order.
Can I write "Cash" as the payee?
Most modern money orders do not allow "Cash" as a payee name. The issuer will either refuse to sell you the money order or will reject it when you try to cash it. If you need to give someone cash, a money order is not the right tool — use cash directly or a prepaid card instead.
What if the amount in numbers does not match the words?
The money order will be rejected. Banks and post offices will not cash it because they cannot tell which amount is correct. You will need to buy a new money order with matching amounts. Always double-check both fields before you leave the counter.
Can I sign a money order and give it to someone else to fill in the payee name?
Technically yes, but it is risky. A signed money order with a blank payee line can be cashed by anyone who has it. The person you give it to could write in their own name instead of the intended recipient. It is safer to fill in the payee name and amount before you sign it.
Do I need to keep the receipt forever?
Keep it until the recipient confirms they cashed the money order and the funds arrived. After that, you can discard it. If a dispute comes up later, you can ask the issuer to look up the money order by number, but having the receipt makes the process faster.
