How to Track a Money Order? 4 Proven Checks to Stop Errors
You can track a money order for free with the receipt stub and the issuer’s status tool. For a USPS money order, enter the serial number, the post office number, and the exact amount online, and the tool tells you in under a minute whether it was cashed. If the free check is not enough, a formal inquiry costs $21.00 (USPS, 2026).
Tracking a money order differs from tracking a parcel. A parcel shows a live map with each scan, while a money order shows only two states: still outstanding or already cashed. That simple answer tells you whether the recipient got paid, while the detail behind it needs the paid inquiry.
ANSWER BOX 1
To track a money order, find the receipt stub and read the serial number, the post office number, and the exact amount. Enter those three details in the free USPS status tool at tools.usps.com, or call 1-866-974-2733. The tool shows at once whether the money order is still outstanding or already cashed.
ANSWER BOX 2
If the free status check is not enough, file a formal Money Order Inquiry with PS Form 6401 at any post office. The inquiry fee is $21.00 per money order, and USPS allows up to 15 days to send the result.
KEY TAKEAWAYS
- Track a USPS money order free with the serial number, post office number, and amount.
- The free tool shows only whether the order is outstanding or already cashed.
- A formal inquiry with PS Form 6401 costs $21.00 per money order, and a replacement can take up to 60 days.

What Does Tracking a Money Order Actually Show?
Tracking a money order shows its payment status, not its location. The free USPS tool returns one of two answers: the order is still outstanding, or it has been cashed. It does not show a map, a delivery scan, or the city where it was cashed.
The status tool needs three details from your receipt stub. The serial number is the 11-digit number printed near the top of the money order, and you enter the first 10 digits online. The post office number names the office that sold it, and the exact amount must match to the cent.
The paid inquiry shows more than the free tool. It can return a photocopy of the cashed money order, which shows who endorsed it and where it was cashed. That copy is the proof you need for a fraud claim or a dispute. Photocopies stay available for two years from the date of cashing.
Money orders from Western Union and MoneyGram track in a similar way. Each issuer has its own online tool and phone line, and each one asks for the serial or reference number from the receipt. The receipt holds the keys, and the free check comes before the paid inquiry.
QUICK ANSWER: Can I track a money order without the receipt?
It is hard, and it may fail. USPS can still file a PS Form 6401 inquiry with the details you recall, such as the date, the office, and the amount. The search takes longer without the serial number, and the $21.00 fee still applies.
How to Track a Money Order in 4 Proven Checks
The four checks below run from free and fast to paid and slow. Start with check one, and move down only when the earlier check leaves a question open. Most tracking jobs end at check one or two.
- Run the free USPS status check online. Open the USPS Money Orders Application at tools.usps.com, and enter the first 10 digits of the serial number, the post office number, and the exact amount. The tool answers in under a minute, and it costs nothing.
- Call the USPS status phone line at 1-866-974-2733, Monday through Friday, 8 AM to 8 PM Eastern Time. Give the same three details from the receipt stub.
- Verify a money order you received with the Verification System. Call 1-866-459-7822 or scan the QR code on the order to confirm it is genuine. This check matters when someone hands you a money order as payment.
- File a formal Money Order Inquiry with PS Form 6401 at any post office. Bring the receipt stub and a valid photo ID, fill in Section A in black ink, and pay the $21.00 fee per money order (USPS, 2026).
Check one is the check most people need. If it says “outstanding,” the recipient has not cashed the order yet, so wait and check again in a few days. If it says “cashed,” the paid inquiry can show who endorsed it. Do not file a paid inquiry before the free check, since the fee is non-refundable.
If you have not bought the money order yet, read our guide on the postal money order for the cost and the steps.
How to Track a Money Order by Issuer: USPS, Western Union, MoneyGram
Each issuer runs its own tracking system, and the receipt details differ slightly. The table below compares the three main issuers side by side. The free check always comes first, and the paid inquiry is the last resort for every issuer.
| Issuer | Free status check | What you need | Paid inquiry fee |
|---|---|---|---|
| USPS | tools.usps.com, or 1-866-974-2733 | Serial number, post office number, exact amount | $21.00 per order (PS Form 6401) |
| Western Union | Track a transfer page or phone line | Money Transfer Control Number from the receipt | About $15.00 to $30.00, varies by case |
| MoneyGram | Track a transfer page or phone line | Reference number from the receipt | About $15.00 to $30.00, varies by case |
USPS tracking is the simplest of the three, since the online tool needs no account and no sign-in. Western Union and MoneyGram also offer online tools, yet they ask for the reference number from the receipt. Keep the receipt for every issuer, since the number on it is the key to every check.
Bank money orders track through the issuing bank, not through USPS. Call the bank or visit a branch with the receipt, and the bank checks its own records. Credit unions follow the same process, and the fee varies by bank.
A money order bought at Walmart tracks through the issuer printed on it, which is usually MoneyGram or Western Union. Look at the receipt to see which issuer sold it, then use that issuer’s tool.
What to Do If Your Money Order Is Lost or Stolen
Act fast when a money order goes missing, since time works against you. Start with the free status check to see whether it was already cashed. If it shows “outstanding,” move at once to the formal inquiry.
File PS Form 6401 at any post office with your receipt stub and a valid photo ID. Fill in every field in Section A in black ink, sign and date the form, and pay the $21.00 fee for each money order (USPS, 2026). The clerk checks your details against the receipt, then mails the form to the USPS Accounting Service Center in St. Louis.
USPS cannot stop payment on a money order the way a bank stops a check. It can only confirm whether the order was cashed and replace one that is confirmed lost or stolen. Confirmation may take up to 30 days, and the full investigation up to 60 days (USPS, 2026).
If the inquiry shows the order was cashed by a stranger, report it at once. Contact the U.S. Postal Inspection Service at 1-877-876-2455 or at uspis.gov/report, and file a police report with the photocopy as proof. Keep every document from the inquiry in one folder until the case closes.
PRO TIP: Photograph the receipt stub and the money order itself before you mail it. The photo gives you the serial number, the amount, and the payee name even if the paper stub is lost.
How Long Does Money Order Tracking Take?
The timeline depends on which check you run, and the free checks are instant. The paid inquiry takes weeks, so set your hopes by the table below.
| Step | How long it takes | Cost |
|---|---|---|
| Free online status check | Under 1 minute | Free |
| Formal inquiry result (PS Form 6401) | Up to 15 days after filing | $21.00 per order |
| Replacement or refund | 60 days or later from issue date | $23.00 replacement fee |
The 60-day wait frustrates many senders, yet it has a reason. USPS must be sure the original order will never be cashed before it issues a replacement, or the same money could be paid twice.
If a tax refund rides on the same timeline, our tax refund calculator helps you plan the wait. Pair the estimate with the inquiry timeline.
5 Money Order Tracking Mistakes That Waste Your Time
These five mistakes slow every tracking job, and each one is easy to avoid. Read the list before you open the status tool.
- Entering the full 11-digit serial number online. The USPS tool wants only the first 10 digits, and the full 11 digits return an error. Type the first 10 digits only.
- Throwing away the receipt stub after mailing the order. The stub holds the serial number, the post office number, and the amount, the three keys to every check. Without it, tracking turns into a slow paper inquiry.
- Filing a paid inquiry before the free check. The free tool answers in under a minute, while the paid inquiry costs $21.00 and takes up to 15 days. Always run the free check first.
- Waiting months to ask about a cashed order. Photocopies of cashed money orders stay available for only two years from the cashing date. A late inquiry can confirm the status, but the proof copy may be gone.
- Using the wrong issuer’s tracking tool. A Walmart money order is usually MoneyGram or Western Union, not USPS, so the USPS tool cannot find it. Read the issuer name on the receipt first.
A tracking job goes smoothly when the receipt is safe and the issuer is known. Photograph the stub on the day you buy the order, and note the issuer name beside it.
