The basic order: payee, amount, memo, signature

A money order has five blanks you need to fill in, and they go in a specific order. Start with the payee line — the name of the person or business who will cash it. Write clearly in pen. Next, fill in the dollar amount in both the box (numerals) and the line next to it (words). Then add a memo if you want — this is optional and just reminds the payee what the money is for. Finally, sign your name on the purchaser line at the bottom. That's it. You do not fill in your own name as the sender unless the money order specifically asks for it.

The layout varies slightly between issuers — Western Union, MoneyGram, USPS, and your bank all format their money orders a little differently — but every one has these same fields in roughly the same places. Before you start writing, scan the form to find each blank. Using pen instead of pencil matters because pen cannot be erased or altered after the fact.

Key Takeaways

  • Write the payee name clearly on the line marked "Pay to the Order of" or similar — this is the person or business cashing the money order.
  • Fill in the dollar amount twice: once as numerals in the box and once as words on the line, and they must match exactly.
  • The memo line is optional and just describes what the money is for, like "rent" or "invoice 4521".
  • Sign only the purchaser line at the bottom in pen; do not sign anywhere else unless instructed.
  • Keep your receipt until the payee confirms they received and cashed the money order.

Writing the payee name correctly

The payee is the only person who can cash the money order, so get this right. Write the full legal name of the person or the exact business name — not a nickname or shortened version. If you are paying a company, use the name that appears on their invoice or website, not "Bob's Plumbing" if the legal name is "Robert's Plumbing LLC." If you are unsure, ask the payee how they want their name written.

Do not leave this line blank and fill it in later. A blank money order can be cashed by anyone who gets their hands on it, which is why you should never sign a blank one either. Write the payee name before you hand over money at the counter.

Filling in the amount in numerals and words

Most money orders have two places for the amount: a box on the right side (for numerals like $150.00) and a line below or beside it (for words like "One Hundred Fifty Dollars"). Both must match exactly. If they do not match, the payee or their bank may reject the money order or only cash it for the smaller amount.

Write the numerals first in the box: $150.00. Then write out the dollar amount in words on the line: "One Hundred Fifty Dollars and 00/100" or simply "One Hundred Fifty Dollars." Some money orders print the word "Dollars" already, so you just fill in the number part. If you make a mistake, do not cross it out — ask the issuer for a replacement. Most will reissue at no charge if you have not yet left the counter.

The memo line and what to write there

The memo line is a small blank, usually near the bottom, that lets you note what the money is for. This is optional — you can leave it blank. But filling it in is useful because it gives both you and the payee a record of the purpose. Write something brief: "Rent for March," "Invoice 2024-456," "Car repair," or "Tuition payment."

The memo is for your records and the payee's records only. It does not affect whether the money order can be cashed. If there is no memo line on your money order, do not worry — it is not required.

Where and how to sign

Sign only the line marked "Purchaser," "From," or "Drawer" — usually at the bottom left of the money order. Use your normal signature, the same one you use on checks. Sign in pen, not pencil. Do not sign any other line on the money order unless the issuer's instructions specifically tell you to.

Some money orders ask for your address or phone number on the back or in a separate field. Fill these in if prompted, but they are not always required. Your signature is what matters. Never sign a money order before you have filled in the payee name and amount — if you do, anyone can cash it.

Common mistakes to avoid

The most frequent error is writing different amounts in numerals and words. If the box says $100 but the words say "Ninety Dollars," the payee's bank may refuse it or only honor the lower amount. Double-check both before you hand it over.

Another mistake is leaving the payee line blank or writing it in pencil. A blank payee line means anyone can cash the money order, and pencil can be erased and changed. Always use pen and always fill in the payee name before you leave the issuer's location.

Do not write your own name as the sender unless the money order has a specific line for it and the issuer asks you to. Most money orders do not require this information. If you are worried about tracking, keep your receipt — that is your proof of purchase.

What to do with your receipt

When you buy a money order, you get a receipt. Keep it until the payee confirms they have received and cashed the money order. The receipt has a tracking number that lets you verify the money order was delivered and cashed. If the payee says they never got it, you can contact the issuer with the receipt and tracking number to find out what happened.

Hold onto the receipt for at least 30 days, longer if you are paying a bill or rent. Once the payee has confirmed receipt, you can throw it away. If you lose the receipt, you can still contact the issuer with the money order number, but the receipt makes it faster.

Frequently Asked Questions

What if I make a mistake filling out the money order?

Do not cross out or erase anything. Ask the issuer for a replacement money order. Most will issue a new one at no charge if you have not left the counter yet. If you have already left, contact the issuer with your receipt and they can cancel the old one and issue a new one, though this may take a few days.

Can I write a money order to myself?

Yes, you can write your own name as the payee. This is sometimes done to deposit a money order into your own bank account or to transfer money between your own accounts. Write your name on the payee line and sign the purchaser line as usual.

Do I need to fill in my address on a money order?

Most money orders do not require your address. Some issuers print a line for it, but it is usually optional. Fill it in if asked, but it is not necessary for the money order to be cashed. Your receipt is your proof of purchase if you need to track it later.

What if the payee's name is very long?

Write it as completely as possible on the payee line. If it does not fit, use the legal name or the name the payee uses on official documents. You can also ask the payee if there is a shorter version of their name or business name that they accept on money orders.

Can someone else cash a money order I filled out?

No, only the person or business whose name is on the payee line can cash it. If you write "John Smith" as the payee, only John Smith can cash it. This is why money orders are safer than cash — they cannot be cashed by anyone who finds them.
