Fill in the payee name first, then the amount, then sign and keep your receipt

A Western Union money order has five fields you need to complete: the payee name (who gets the money), the amount in numbers and words, your name and address as the purchaser, and your signature. You fill these in at the counter when you buy the money order, not before. The cashier will print some fields for you — your job is to write the payee information clearly and sign where instructed. Keep the receipt stub; you will need it if the money order is lost or never cashed.

The process takes about five minutes. Western Union money orders are sold at thousands of locations — grocery stores, pharmacies, check-cashing shops, and Western Union agents — so you do not have to visit a bank. You pay the face value of the money order plus a fee (usually a few dollars, depending on the amount). The money order itself is the proof of payment, so once you hand it over, the recipient can cash it at most banks and check-cashing locations.

Key Takeaways

  • Write the payee name clearly in the "Pay to the Order of" field — this is the person or business that will cash the money order.
  • Write the amount in both numbers (in the box) and words (on the line), and make sure both match exactly.
  • Sign the money order in the purchaser signature line; do not sign the back or anywhere else.
  • Keep your receipt stub until you confirm the money order was cashed, because you will need it to report a lost or stolen money order.
  • Do not leave any field blank — a blank payee name or amount makes the money order worthless.

The payee field: who the money goes to

The "Pay to the Order of" line is where you write the name of the person or business that will receive the money. Write the name exactly as the recipient will present it when they cash the money order — if they go by a nickname but their legal name is different, use the legal name. Print clearly in pen, not pencil. Do not use abbreviations unless the recipient specifically asks you to.

If you are sending the money order to a business, write the business name as it appears on their invoices or official documents. For example, write "ABC Plumbing LLC" rather than "ABC Plumbing" if that is the registered name. If you are unsure of the exact legal name, ask the recipient before you buy the money order — you cannot change this field after purchase without voiding the money order.

The amount: numbers and words must match

Western Union money orders require you to write the amount twice: once in numbers in a box (for example, $150.00) and once in words on a line below it (for example, "One hundred fifty dollars"). Both must be identical. If they do not match, the money order is invalid and the recipient cannot cash it.

Write the numerical amount with the dollar sign and two decimal places, even if you are sending a whole dollar amount with no cents. For the words, spell out the dollar amount and write "dollars" at the end. If there are cents, write them as a fraction — for example, "One hundred fifty and 50/100 dollars." Take your time with this step; a mismatch here is the most common reason a money order gets rejected at the bank.

Your name and address as the purchaser

The cashier will usually print your name and address on the money order from your ID or from information you provide. If you are buying the money order in person and paying cash, you may be asked to provide your address verbally. If you are buying online or by phone, you will enter this information yourself. This field identifies you as the person who purchased the money order, not the recipient.

Make sure the address printed is correct and current. If it is wrong, tell the cashier before you complete the purchase. Some locations will let you correct it; others will void the money order and issue a new one. Do not try to cross out or write over a printed address — that makes the money order look altered and may cause it to be rejected.

Your signature: the final required field

Sign the money order in the "Purchaser Signature" or "Drawer Signature" field. This is usually on the front of the money order, below or to the right of the amount. Use the same signature you use on checks and legal documents. Do not print your name in this field — a signature is required.

Sign in pen, not pencil, and do not sign the back of the money order or anywhere else. If you make a mistake on your signature, ask the cashier for a new money order rather than crossing it out. A corrected or unclear signature can cause the money order to be rejected when the recipient tries to cash it.

Fields the cashier fills in for you

The money order number, the date, and the issuing location are printed by the Western Union system or written by the cashier. You do not fill these in. The money order number is unique to that specific money order and is how Western Union tracks it if you need to report it lost or stolen. The date is the date of purchase. Do not try to change either of these fields — doing so voids the money order.

Some money orders also have a "Memo" field where you can write a note about what the money is for (for example, "Rent for January" or "Invoice #12345"). This field is optional and does not affect whether the money order is valid, but it can be helpful for record-keeping on both ends.

What to do with your receipt

When you buy a Western Union money order, you receive a receipt stub that is attached to or printed separately from the money order itself. Tear off or keep this receipt — it has the money order number, the amount, the payee name, and the date. Store it in a safe place until the recipient confirms they have cashed the money order.

If the money order is lost, stolen, or never cashed after a reasonable time (usually 30 to 90 days, depending on Western Union's policy), you will need this receipt to file a claim. Without it, Western Union cannot look up the money order or issue a replacement. Keep the receipt for at least three months, or longer if you are sending the money order through the mail.

Common mistakes to avoid

The most frequent errors are leaving the payee name blank, writing different amounts in numbers and words, or forgetting to sign. Any of these makes the money order invalid. Another common mistake is writing the payee name in cursive that is hard to read, or using a name the recipient does not recognize — if the name on the money order does not match the ID the recipient shows when cashing it, the bank may refuse to cash it.

Do not write a money order to "Cash" or "Bearer" — Western Union money orders require a specific payee name. Do not try to make corrections by crossing out and rewriting; if you make a mistake, ask for a new money order. Do not sign the back or write anything on the back of the money order unless Western Union specifically instructs you to do so.

Frequently Asked Questions

Can I change the payee name after I buy the money order?

No. Once the money order is printed with a payee name, you cannot change it. If you wrote the wrong name, you will need to contact Western Union to void the money order and purchase a new one. This is why it is important to confirm the payee name before you hand over your money.

What if the amount in numbers and words do not match?

The money order will likely be rejected when the recipient tries to cash it. Banks and check-cashing locations will not accept a money order with mismatched amounts because it is unclear what the actual value is. If this happens, you will need to contact Western Union with your receipt to report the error and request a replacement.

Do I need to sign the back of the money order?

No. You sign only the front, in the purchaser signature field. The recipient may need to sign the back when they cash it, but that is their responsibility, not yours. Do not write anything on the back unless Western Union or the recipient specifically asks you to.

What happens if I lose the receipt?

If the money order is lost or never cashed, you will have a much harder time proving you purchased it and getting a refund without the receipt. The receipt has the money order number, which is the only way Western Union can track it. Always keep the receipt until the money order is confirmed cashed.

Can someone else cash a Western Union money order if I made a mistake on the payee name?

No. The money order can only be cashed by someone whose name matches the payee name on the money order. If you wrote the wrong name, the money order cannot be used by anyone else. You will need to void it and purchase a new one with the correct payee name.
