What a postal money order is and when to use one
A postal money order is a payment method you buy at the post office that works like a check, but the funds are may provide because you pay for it upfront. You hand over cash or a debit card, the postal clerk issues you a slip of paper with a specific dollar amount printed on it, and you send that slip to whoever you owe money to. The recipient takes it to any post office or bank to cash it.
Postal money orders are useful when you need to send money through the mail to someone who won't accept a personal check, or when you don't have a bank account. They're also common for paying bills to government agencies, security deposits on rentals, or sending cash to family without the risk of loose bills getting lost or stolen in transit.
The post office issues them up to a maximum of $1,000 per money order. If you need to send more than that, you can buy multiple money orders in the same transaction.
Key Takeaways
- You buy a postal money order at any post office location by paying the full amount in cash or with a debit card, plus a small fee that varies by the dollar amount.
- The recipient can cash or deposit a postal money order at any bank or post office without needing an account.
- You should record the money order number and keep your receipt until the recipient confirms they received and cashed it.
- If a money order is lost or stolen, you can request a replacement through the post office, but the process takes time and requires your original receipt.
How to buy a postal money order at the post office
Walk into any post office location with the cash or debit card you want to use. Tell the clerk you want to buy a money order and tell them the amount. The clerk will ask you for the name of the person or business the money order is for (the payee) and may ask for your name and address for their records.
The post office charges a fee for each money order. The fee depends on the amount: smaller amounts (usually under $500) cost less than larger ones. Fees typically range from about $1.45 to $2.00 per money order, though this can vary by location. You pay both the money order amount and the fee at the counter.
The clerk will hand you the money order slip, your receipt, and any change. The money order will have a serial number printed on it. Write down that number on your receipt or in a notebook — you'll need it if the money order goes missing.
What information goes on a postal money order
The money order itself contains several pieces of information printed by the post office. The payee name (who will cash it) is filled in at the counter. The amount in dollars is printed. Your name and address go in a specific box so the post office knows who bought it. The serial number is unique to that money order.
You should not leave the payee line blank. If you do, anyone who finds the money order can fill in their own name and cash it. Some people make the mistake of thinking they can leave it blank and hand it to someone to fill in later — this creates a security risk and some recipients won't accept it that way.
On the back of the money order, there is a space for the recipient to sign and endorse it before cashing. The recipient fills this in when they go to cash it, not before.
How the recipient cashes or deposits a postal money order
The person you send the money order to can take it to any post office or any bank to cash it or deposit it into an account. They don't need to have an account at that bank — most banks will cash postal money orders for non-customers, though some may charge a small fee.
The recipient signs the back of the money order and shows a photo ID. The post office or bank verifies the money order is legitimate (this is usually instant) and hands over the cash or deposits the funds into the account they specify.
This is why postal money orders are safer than sending cash: the recipient has to prove who they are to get the money, and you have a record of the serial number in case something goes wrong.
What to do if your money order is lost or stolen
If the money order never reaches the recipient or if it's stolen before they can cash it, you can request a replacement. Go back to the post office where you bought it with your original receipt. The clerk will file a claim for a refund or replacement.
The post office will search their records to see if the money order has been cashed. This search takes time — usually several weeks. If it hasn't been cashed, they will issue you a replacement money order for the same amount, or refund your money if you prefer.
This is why keeping your receipt is critical. Without it, the post office cannot look up the serial number or process a claim. If you lose both the money order and the receipt, you have no way to recover the funds.
Postal money orders versus other payment methods
Postal money orders cost more than writing a check (which is free if you have checks printed) but less than a wire transfer or cashier's check. They're slower than electronic payment but faster and more secure than mailing cash. They work when the recipient won't take a personal check but will take a money order.
If you need to send money to someone and you have a bank account, a cashier's check from your bank is often a better choice because it's larger (up to the full amount you request) and the bank handles the paperwork. If you don't have a bank account or need the money order today, the post office is the standard option.
Wire transfers are faster but cost more and require both parties to have bank accounts. Electronic payment apps like Venmo or PayPal are free but only work between people who both have accounts and trust the platform. Postal money orders work for almost anyone and don't require an account anywhere.
Common mistakes to avoid when using postal money orders
The most common mistake is not writing down the serial number. If the money order disappears, you have no proof you bought it and no way to trace it. Write the number on your receipt or in a separate notebook the moment you get it.
Another mistake is leaving the payee line blank. This makes the money order a security risk and some recipients won't accept it. Fill in the payee name at the post office before you leave.
A third mistake is not keeping your receipt. If you need to file a claim, the post office will ask for it. Throw it away only after the recipient confirms they've cashed the money order.
Some people also buy money orders for amounts larger than they need, thinking they can get change. You can't — you have to buy the exact amount. If you need to send $47, you buy a $47 money order, not a $50 one.
Frequently Asked Questions
Can I buy a postal money order online or by phone?
No. You must go to a physical post office location and buy it in person. You cannot order one online or by phone. Some post offices are inside grocery stores or pharmacies, so you may have more locations near you than standalone post offices.
What if I make a mistake filling out the money order?
If you make a mistake before you leave the post office, tell the clerk immediately. They can void it and issue a new one. If you've already left, you cannot correct it — you would have to go back and request a replacement, which involves a claim process and takes weeks.
Do I need an ID to buy a postal money order?
You don't always need an ID, but the post office may ask for one. Bring a photo ID to be safe. The clerk will record your name and address for their records regardless.
How long does it take for a postal money order to reach someone?
That depends on how you send it. If you mail it through the post office, it takes the same time as regular mail — typically three to five business days for delivery. If you hand it to someone in person, they can cash it immediately. The money order itself doesn't have a processing time once it arrives.
Can I get my money back if I change my mind after buying a money order?
Yes, but only if you haven't sent it yet. Go back to the post office with your receipt and the unused money order. They will refund your money minus the fee you paid. Once you've mailed it or given it to someone, you cannot get a refund — only a replacement if it's lost or stolen.
