The order of filling in a money order matters, and you fill it the same way whether you're at a bank, post office, or convenience store

A money order has blank spaces for the sender's name, the recipient's name, the amount, and sometimes a memo line. You fill these in with a pen — not pencil — in the order the form shows them. The exact layout varies slightly by issuer, but the sequence is always: who is sending it, who receives it, how much, and any note about what it's for. Most money orders also have a stub on the left side that you keep as your receipt; fill that in at the same time with the same information.

The most common mistake is writing the recipient's name in the wrong blank. Money orders have two name fields: one for the purchaser (you, the person buying it) and one for the payee (the person or business receiving the money). If you reverse these, the money order won't work the way you intend, and the recipient may not be able to cash it.

Key Takeaways

  • Write in pen only, never pencil, and use the name fields in the correct order: your name first, then the recipient's name.
  • The amount goes in two places on most money orders — once in numbers and once written out in words — and both must match exactly.
  • Fill in your stub (the part you keep) at the same time you fill in the money order itself, so you have a record of what you sent.
  • Leave the memo line blank unless you need to note what the payment is for, such as "rent" or an account number.

Where to write your name and the recipient's name

The first blank line is labeled "From," "Purchaser," or "Sender" — this is where you write your full name. Use the name that matches your ID, since you may need to show identification when you buy the money order. Write clearly and completely; abbreviations can cause confusion later.

The second name field is labeled "Pay to the Order of" or "Payee" — this is where you write the name of the person or business that will receive the money. If it's a business, write the exact legal name as it appears on bills or invoices. If the recipient's name is long, write it as completely as you can fit in the space. Do not use nicknames or shortened versions.

Some money orders ask for an address for both the sender and the payee. Fill these in if the form has the lines. Your address helps the issuer contact you if there's a problem; the payee's address is optional on most forms but useful if the recipient needs to deposit it at a bank.

How to write the dollar amount correctly

Money orders require the amount in two formats: numerals in a box or line labeled "Amount" or "$," and the same amount written out in words on a line labeled "Dollars" or similar. Both must be identical. If they don't match, the money order may be rejected or the recipient may not be able to cash it.

For the numerical amount, write it in the box or on the line provided, using a dollar sign and decimal point — for example, $45.50. For the written-out version, spell the number in words: "Forty-five dollars and fifty cents" or "Forty-five and 50/100 dollars." The second format (with the fraction) is more common on official money order forms. If you're sending a whole dollar amount with no cents, write "Fifty dollars and 00/100" or straightforward "Fifty dollars."

Write both amounts clearly and leave no blank space after the written-out amount — some people draw a line to fill the gap so no one can add digits later. Double-check that both versions match before you hand over the money order.

The memo line and what to write there

Most money orders have a small line labeled "Memo," "For," or "Note." This line is optional and is meant for you to record what the payment is for — for example, "Rent for March," "Invoice #12345," or "Car payment." The memo helps both you and the recipient keep track of what the money order covers.

If you're paying a bill or sending money for a specific purpose, write a brief note here. Keep it short; the space is limited. If the recipient has given you an account number or reference number, this is where you write it. If there's no specific reason to note anything, you can leave this line blank.

Filling in your stub and keeping your receipt

The stub — the part attached to the left side of the money order that you tear off and keep — is your proof of purchase and your record of the transaction. Fill it in with the same information you wrote on the money order itself: your name, the payee's name, the amount, and the date. The stub also has a tracking number that matches the money order, so you can look up whether it was cashed.

Write the date on both the stub and the money order. Use the date you're purchasing it, not a future date. Keep the stub in a safe place until you confirm the recipient has received and cashed the money order. If there's ever a dispute about whether you sent the money, the stub is your proof.

Common errors to avoid when filling in a money order

Writing the recipient's name in the "From" field instead of the "Pay to" field is the most common error. This makes the money order payable to the wrong person. If you make this mistake before you buy the money order, start over with a new form. If you've already purchased it, contact the issuer when ready — some will cancel and reissue it, but policies vary.

Using pencil instead of pen is another frequent mistake. Pencil can smudge or be erased, which raises fraud concerns and may cause the money order to be rejected. Always use a ballpoint or gel pen with dark ink.

Leaving the amount blank or writing different amounts in the two fields will prevent the money order from being cashed. The recipient won't be able to deposit it, and you'll have to contact the issuer to correct it. Mismatched amounts are treated as a red flag by banks and can delay the process.

Writing a post-dated money order (a future date instead of today's date) doesn't work the way it does with checks. Money orders can usually be cashed when ready regardless of the date written on them. If you need the recipient to receive the money on a specific date, send it closer to that date rather than trying to post-date it.

What to do if you make a mistake

If you notice an error before you hand over the money order, ask the seller for a new blank form. Most sellers will give you one at no extra charge if you haven't yet paid for the money order. If you've already paid and then notice a mistake, contact the issuer — this could be your bank, the post office, Western Union, MoneyGram, or a convenience store, depending on where you bought it.

The issuer can cancel the money order and issue a replacement, but this process takes time and may involve a fee. Some issuers charge $1 to $5 to replace a money order. Keep your receipt (the stub) and any documentation from the issuer in case you need to follow up.

Frequently Asked Questions

Can I use pencil to fill in a money order?

No. Use pen only. Pencil can smudge, fade, or be erased, which raises fraud concerns and may cause the money order to be rejected by a bank or the recipient.

What happens if the amount in numbers doesn't match the amount in words?

The money order may be rejected or the recipient may not be able to cash it. Banks and businesses treat mismatched amounts as a potential fraud indicator. Contact the issuer to cancel and replace it if this happens.

Do I have to fill in the memo line?

No, the memo line is optional. Fill it in if you want to note what the payment is for or include a reference number, but it's not required for the money order to work.

Can I write a money order to myself?

Yes. Write your own name in the "Pay to the Order of" field. You can then cash it or deposit it into your account. This is sometimes done to transfer money between accounts or to create a record of a transaction.

What if I write the wrong recipient's name and already paid for it?

Contact the issuer (your bank, post office, or the store where you bought it) right away with your receipt. They can cancel it and issue a replacement, though there may be a small fee and a wait of several business days.
