Most places won't let you pay for a money order with a credit card, but a few routes exist
You cannot buy a money order directly with a credit card at most retailers and banks. Western Union, MoneyGram, USPS, and most grocery stores and check-cashing outlets treat money orders as cash-equivalent products and require payment in debit card, cash, or sometimes PIN-based methods only. The restriction exists because money orders are final transactions — once issued, they cannot be reversed — so payment processors treat them like cash withdrawals rather than purchases.
However, three workarounds exist: you can use a credit card to withdraw cash from an ATM (though this usually costs a fee), you can buy a money order through a third-party service that accepts credit cards, or you can use a cash advance feature if your card issuer offers it. Each option has different costs and timing, and which one makes sense depends on why you need the money order and how much you're willing to pay in fees.
Key Takeaways
- Western Union, MoneyGram, USPS, and retail locations do not accept credit cards for money order purchases because money orders are treated as cash-equivalent products.
- Using a credit card to withdraw cash from an ATM and then buying a money order with that cash works but typically costs $3 to $5 in ATM fees plus the money order fee itself.
- Some third-party payment platforms and bill-pay services accept credit cards and can issue money orders, though these often charge higher fees than buying directly.
- A cash advance from your credit card issuer is possible but usually costs 3 to 5 percent of the amount plus daily interest starting immediately, making it the most expensive option.
Why credit cards are blocked for money order purchases
Money orders are treated as cash equivalents by payment networks and financial institutions. Once a money order is issued and signed, it cannot be cancelled or reversed — the issuer has no way to recover the funds if something goes wrong. Credit card networks require the ability to reverse or dispute transactions, which is why they block purchases that act like cash withdrawals.
This same rule applies to other cash-like products: you cannot buy gift cards, prepaid cards, or cryptocurrency with most credit cards for the same reason. The restriction protects both the card issuer and you, because it prevents someone from using a stolen card to instantly convert credit into untraceable cash.
Using an ATM cash withdrawal to buy a money order
The simplest workaround is to withdraw cash from an ATM using your credit card, then use that cash to buy a money order at any location that sells them. This works at USPS locations, Western Union, MoneyGram, grocery stores, Walmart, and check-cashing outlets. The money order itself costs $1 to $5 depending on the amount and issuer, and the ATM withdrawal typically costs $3 to $5 in fees.
The total cost is higher than paying with a debit card, but the process is straightforward and takes about 10 minutes. Be aware that ATM cash advances often carry a higher interest rate than regular purchases — sometimes 25 to 30 percent APR — and interest starts accruing immediately, not at the end of your billing cycle. If you pay off the cash advance within a few days, the interest cost is minimal, but if it sits on your card for a month, the fee can exceed the money order cost itself.
Third-party payment services that accept credit cards
Some online bill-pay platforms and money transfer services accept credit cards and can issue money orders, though they are less common than direct retailers. Services like Plastiq and certain payment apps allow you to pay bills or send money using a credit card, and some can issue money orders as part of that service. However, these platforms typically charge a processing fee of 2 to 3 percent of the transaction amount on top of the money order fee, making the total cost significantly higher than buying directly.
These services are most useful if you need the money order sent directly to a specific address or if you are already using the platform for other payments. If you are only buying a single money order, the extra fees usually make this option more expensive than the ATM withdrawal method. Check the platform's fee structure before committing, because fees vary widely and some services have changed their policies around money orders in recent years.
Cash advances from your credit card issuer
Your credit card issuer may offer a cash advance feature that lets you withdraw cash directly from your credit line. You can do this at an ATM, at a bank branch, or sometimes through a check written against your credit account. Once you have the cash, you can buy a money order the same way you would with ATM cash.
Cash advances are expensive: most issuers charge an upfront fee of 3 to 5 percent of the amount withdrawn, plus a higher interest rate than regular purchases — often 25 to 30 percent APR. Interest begins accruing immediately, with no grace period. For a $500 money order, a cash advance would cost $15 to $25 in fees alone, plus daily interest. This is the most costly option and should only be used if you have no other way to get cash.
Comparing the cost of each method
| Method | Upfront Cost | Interest Rate | Total Cost for $500 Money Order |
|---|---|---|---|
| ATM withdrawal + money order | $3–$5 ATM fee + $1–$5 money order fee | 25–30% APR (if not paid immediately) | $4–$10 if paid within days; $15+ if held for a month |
| Third-party payment service | 2–3% processing fee + $1–$5 money order fee | None (charged as a purchase) | $10–$20 |
| Credit card cash advance | 3–5% cash advance fee + $1–$5 money order fee | 25–30% APR (starts immediately) | $15–$25 upfront; $30+ if held for a month |
The ATM withdrawal method is the cheapest option if you pay off the cash advance within a few days. The third-party service is more predictable because it charges a flat processing fee with no ongoing interest, but the fee is higher upfront. A cash advance is the most expensive and should be avoided unless you have no other option.
When you might want to use each method
Use the ATM withdrawal method if you need a money order today and can pay off the cash advance within a week. The short-term interest cost is minimal, and the total fee is lower than other options. This works best for small amounts under $500.
Use a third-party payment service if you need the money order sent to a specific address, if you are already using the platform for other payments, or if you want to avoid the interest rate risk of a cash advance. The fee is higher, but it is fixed and predictable.
Avoid a cash advance unless you have no other way to get cash. The combination of an upfront fee and a high interest rate makes this the most expensive option by far, especially if you cannot pay it back immediately.
Frequently Asked Questions
Can I use a debit card to buy a money order instead?
Yes, debit cards are accepted at nearly all money order retailers, including USPS, Western Union, MoneyGram, and grocery stores. A debit card is the cheapest way to buy a money order because you only pay the money order fee itself, with no ATM or cash advance fees. If you have a debit card, use it instead of a credit card.
Will buying a money order with a credit card hurt my credit score?
A cash advance will show up on your credit report as a separate transaction type and may lower your score slightly because it increases your credit utilization. However, the impact is usually small if you pay it off quickly. The bigger concern is the interest cost, not the credit score impact.
Can I use a prepaid credit card to buy a money order?
No, prepaid cards are treated the same way as regular credit cards and are blocked from money order purchases. However, if your prepaid card is linked to a bank account, you may be able to withdraw cash from an ATM and then buy a money order with that cash, depending on the card's terms.
What if I need a money order urgently and have no other payment method?
The ATM withdrawal method is fastest — you can withdraw cash and buy a money order within 10 to 15 minutes at most locations. If your bank or credit union is closed, find a 24-hour ATM at a convenience store or supermarket, then buy the money order at a location that is open late, such as Walmart or a 24-hour grocery store.
Are there any credit cards that accept money order purchases?
No major credit card networks allow money order purchases directly. Some credit unions or small banks may have different policies, so you can contact your card issuer to ask, but the answer is almost always no. The restriction is enforced by the payment networks themselves, not individual card issuers.
