Fill out the money order in this order: payee name, amount in numbers, amount in words, your name and address, memo line, and your signature

Western Union money orders have blank fields printed on the front. You fill them in with a pen (not pencil) before you pay for the money order at the counter. The cashier will not complete any fields for you — that is your job. If you make a mistake, ask for a new form; you cannot cross out or use correction fluid.

The order matters because some fields feed into others. Start with the payee (the person or business receiving the money), then the dollar amount, then your details. This sequence prevents you from writing the amount in the wrong place or forgetting a required field.

Key Takeaways

  • Write the payee name on the "Pay to the Order of" line first, before you write any amount.
  • Write the dollar amount twice: once in the box labeled with a dollar sign, and once spelled out on the line below it.
  • Print your name and address on the "From" line so Western Union can contact you if the money order is lost.
  • Sign the money order only after you have filled in all other fields, and sign in the box labeled "Purchaser Signature."
  • Keep your receipt stub until the payee confirms they received and cashed the money order.

Where each piece of information goes on the form

The "Pay to the Order of" line is at the top left of the money order. Write the name of the person or business that will cash it. Use the exact legal name if you know it — for a business, write the full company name rather than a shortened version. Do not use a nickname or abbreviation unless that is how the account is registered.

The amount box is usually in the upper right corner and has a dollar sign printed next to it. Write the number amount here: $150.00, $500.50, whatever the sum is. Use numbers only, and include cents even if the amount is a whole dollar (so $200.00, not $200).

Below the amount box is a line that says "Dollars" or similar. Spell out the dollar amount in words on this line: "One Hundred Fifty and 00/100" or "Five Hundred and 50/100." Write the whole number part in words, then write the cents as a fraction over 100. This redundancy is a fraud check — if the numbers do not match the words, the money order may be rejected.

The "From" section has lines for your name and address. Print your full name and the address where Western Union can reach you if something goes wrong. This is not optional; Western Union needs this information to trace the money order if it is lost or stolen before the payee cashes it.

Some money orders have a "Memo" or "For" line. This is optional and is for your own record-keeping — write what the money is for (rent, invoice #12345, tuition, etc.). The payee will see this, so keep it brief and professional.

Signing the money order correctly

Sign the money order only after every other field is complete. Your signature goes in the box labeled "Purchaser Signature" or "Drawer Signature," usually at the bottom right. Sign your name the same way it appears on your identification — Western Union may ask to see ID when you purchase the money order, and the signature should match.

Do not sign before you fill in the payee and amount. If you sign a blank money order and then lose it, anyone can fill in their own name and cash it. The signature is the last step for this reason.

Common mistakes to avoid

Writing the amount in words but not in numbers (or vice versa) is the most common error. Both fields must be filled in, and they must match. If you write "One Hundred Dollars" in words but "$50.00" in numbers, the money order will be rejected or held for verification.

Using pencil instead of pen is another mistake. Pencil can be erased, which makes the money order look fraudulent. Use a ballpoint pen and press firmly so the writing is clear and permanent.

Leaving the "From" section blank will delay the money order if it is lost. Western Union needs your information to investigate and replace it. Some locations will refuse to sell you a money order without this information.

Writing an illegible payee name causes problems for the person cashing it. Print clearly, even if it means writing slowly. If the name is hard to read, the bank or check-cashing service may reject it or ask the payee for extra identification.

What to do with your receipt

Western Union tears off a receipt stub when you purchase the money order. Keep this receipt until the payee tells you they have cashed it. The receipt has a tracking number that lets you confirm the money order was received and processed.

If the payee says they never got the money order, you can contact Western Union with your receipt number and ask them to trace it. They can tell you whether it was cashed and by whom. If it was not cashed, Western Union can issue a replacement or refund, but you need the receipt number to do this.

Do not throw away the receipt immediately after sending the money order. Wait at least one week, or until the payee confirms receipt, before discarding it.

Frequently Asked Questions

Can I use pencil or pen to fill out a Western Union money order?

Use pen only. Pencil can be erased, which makes the money order appear fraudulent and may cause it to be rejected by the bank or check-cashing service. A ballpoint pen is standard and acceptable everywhere.

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

Do not try to fix it. Ask the cashier for a new blank money order form and start over. Crossing out, using correction fluid, or scratching out errors will cause the money order to be rejected. Western Union will not charge you for a replacement form if you made the error.

Do I have to fill in the memo line?

No, the memo line is optional. It is for your reference and the payee's reference only — it does not affect whether the money order is valid. Write something brief if it helps you remember what the payment was for, but it is not required.

What if I do not know the exact legal name of the business I am paying?

Write the name exactly as it appears on the invoice or bill you are paying. If you are unsure, contact the business and ask for the correct legal name to use on the money order. Using the wrong name can cause the money order to be rejected or delayed.

Can someone else cash a Western Union money order if I fill in their name?

Yes. Once you write someone's name on the "Pay to the Order of" line, only that person (or someone they authorize) can cash it. This is why you must write the correct name — if you misspell it or use the wrong name, the payee may not be able to cash it without extra steps.
