Fill in the payee name first, then the amount, then sign it

A money order has five blanks you need to complete: the payee (who gets the money), the amount in numbers, the amount in words, your name and address, and your signature. Fill them in that order, using a pen with black or blue ink. Write clearly and stay inside the lines — the postal service or bank processing the money order needs to read what you wrote, and messy handwriting can delay payment or cause the money order to be rejected.

Do not cross out mistakes or use correction fluid. If you make an error, ask the seller for a new money order. Most places will exchange it for free if you have not signed it yet. Once you sign, the money order is yours to keep or give away — the seller cannot take it back.

Money orders do not expire, but they can become harder to cash after a long time. Most financial institutions will cash one that is years old, but some have time limits. If you are holding a money order for more than a few months, cash it or deposit it soon rather than waiting.

Key Takeaways

  • Write the payee name on the "Pay to the Order of" line — this is the person or business that will receive the money.
  • Write the dollar amount twice: once in the box with numbers (like $50.00) and once spelled out in words (like "Fifty dollars and 00/100").
  • Sign the money order in the signature box; without your signature, the payee cannot cash it.
  • Use black or blue pen and write clearly, because illegible money orders may be rejected by banks or post offices.
  • Keep your receipt until the money order is cashed, so you can track it or stop payment if it is lost or stolen.

Where each blank goes and what to write

The "Pay to the Order of" line is where you write the name of the person or business receiving the money. Write the full legal name if you know it — "John Smith" instead of "J. Smith", or "ABC Plumbing LLC" instead of "ABC Plumbing". If the payee is a business and you do not know the legal name, write it the way it appears on their invoices or website.

The amount box (usually marked with a dollar sign or "Amount") is where you write the number: $50.00, $125.50, and so on. Write it as far left as possible in the box, and include cents even if the amount is a whole dollar. Next to or below that is a line where you spell out the same amount in words: "Fifty dollars and 00/100" or "One hundred twenty-five dollars and 50/100". The fraction at the end represents cents out of 100. If you are unsure how to spell a large number, write it out on scratch paper first.

The "From" or "Purchaser" section is where you write your name and address. This is how the issuer (the post office or bank) tracks who bought the money order, and it is also how the payee can contact you if there is a problem. Use your current address, not a P.O. box, because some businesses will not accept money orders with only a box number.

Signing and protecting the money order

Sign the money order in the signature box only when you are ready to give it to the payee or deposit it. Your signature is what makes the money order valid — without it, the payee cannot cash it. Do not sign it early or sign it in front of the seller; sign it only when you hand it over or when you are about to mail it.

If you sign a money order and then lose it or change your mind, you can stop payment through the issuer. Contact the post office or bank where you bought it with your receipt and the money order number. There is usually a fee (often $15 to $30), and the process takes a few weeks. This is why keeping your receipt is important — without it, stopping payment is much harder.

Do not write anything else on the money order. Do not add a memo line, do not write "For rent" or "For invoice #123" in the margins, and do not cross out or change anything after you have written it. Money orders are formal financial documents, and extra writing can cause them to be rejected.

Common mistakes that delay or reject money orders

The most common error is writing the amount in numbers and words differently — for example, writing $50.00 in the amount box but spelling out "Forty dollars" on the line. Banks and post offices will reject the money order and ask you to buy a new one. Double-check both amounts before you hand it over.

Writing an illegible payee name is another frequent problem. If the name is unclear, the payee may not be able to cash it, or the wrong person might cash it. Print clearly, and if the payee is a business with a long or unusual name, ask them how they want it written.

Forgetting to sign the money order is also common. The payee will not be able to cash an unsigned money order, and they will have to contact you to sign it. This delays payment and creates extra work. Before you hand over or mail the money order, check that you have signed it.

Mailing a money order safely

If you are mailing a money order, do not send it in a regular envelope without tracking. Use a method that gives you proof of delivery — certified mail with return receipt, Priority Mail Express, or a courier service. Write down the money order number and keep your receipt in case the money order is lost in the mail.

Include a letter or note with the money order that states the payee name, the amount, and what the payment is for (rent, invoice number, etc.). This helps the recipient match the money order to the correct account or bill. Do not mail cash, and do not mail a money order in an envelope that looks like it contains money.

If you are paying a bill or rent, ask the payee whether they prefer a money order or another payment method. Some businesses have stopped accepting money orders because they take time to process. Knowing their preference before you buy the money order saves you a trip.

When to use a money order instead of other payment methods

Money orders are useful when the payee does not accept credit cards or digital payments, when you do not have a bank account, or when you want a record of payment without using a personal check. They are also safer than cash because they can be stopped if lost or stolen, and they provide proof that you paid.

Money orders are not the fastest payment method. They take several business days to clear, and some businesses process them slowly. If you need the payment to arrive immediately, a wire transfer or digital payment is faster. If the payee is local and accepts cash, that is also faster than mailing a money order.

For large payments, money orders have limits. Most post offices and banks cap money orders at $500 to $1,000 per order, so you may need to buy multiple money orders. Check with the issuer before you go in, so you know how many you need to buy.

Frequently Asked Questions

Can I write a money order to myself?

Yes. Write your own name on the "Pay to the Order of" line. This is useful if you want to deposit a money order into your bank account or if you are transferring money between accounts. You will still need to sign it and provide your address in the "From" section.

What happens if I write the wrong amount in words or numbers?

The money order will likely be rejected. Most financial institutions will not cash a money order if the written amount and the numerical amount do not match. Ask the seller for a replacement money order and fill it out again carefully. Do not try to cross out or correct the error.

Can I use a pencil or marker instead of pen?

No. Use only black or blue pen. Pencil can be erased, and markers may bleed through the paper or be hard to read. Banks and post offices have strict rules about how money orders must be filled out, and using the wrong writing tool can cause rejection.

What if the payee's name is very long or has special characters?

Write it as completely and clearly as possible. If the name is longer than the line, ask the payee how they want it abbreviated or written. For businesses with special characters (like "&" or "LLC"), include them exactly as they appear in the legal name. If you are unsure, contact the payee before you buy the money order.

Do I need to keep the receipt after the money order is cashed?

You can discard it once the payee confirms they received and cashed the money order. However, keep it for at least 30 to 60 days in case there is a dispute or the money order is lost. If you need to stop payment or track the money order, the receipt number is essential.
