Yes, you can use a credit card to buy a money order, but most sellers will not let you
Most places that sell money orders — banks, post offices, grocery stores, check-cashing outlets — do not take credit cards as payment. They accept cash, debit cards, and sometimes traveler's checks. A few will take a debit card but refuse credit. The reason is straightforward: money orders are meant to be a safer alternative to cash or checks, and sellers want to avoid the fraud risk that comes with credit card transactions for this particular product.
If you need a money order and only have a credit card, your realistic options are narrow. You can withdraw cash from an ATM using your credit card (which costs a cash advance fee), then use that cash to buy the money order. Or you can find one of the rare sellers who do take credit cards — usually larger banks or Western Union locations — though even these are not may provide to accept yours.
The core problem is that using a credit card to buy a money order is a form of a cash advance, and most financial institutions treat it that way, whether or not the seller technically accepts the card.
Key Takeaways
- Post offices, grocery stores, and check-cashing outlets almost never accept credit cards for money order purchases.
- If you use a credit card to buy a money order through any method, your card issuer may charge a cash advance fee, typically 3 to 5 percent of the amount.
- A cash advance also starts accruing interest when ready, with no grace period like you get on regular purchases.
- Withdrawing cash from an ATM using your credit card and then buying the money order with cash is the most common workaround, but it still triggers cash advance fees and rates.
- Some Western Union locations and larger banks may accept credit cards for money orders, but policies vary by location and card issuer.
Why most money order sellers reject credit cards
Money order sellers treat credit card transactions as a higher fraud risk than cash or debit transactions. If someone uses a stolen credit card to buy a money order, the cardholder can dispute the charge weeks or months later. By that time, the money order may have already been cashed and the funds transferred. The seller is left holding the loss.
With cash or a debit card, the transaction is final. The money is gone when ready, and there is no chargeback window. This is why the U.S. Postal Service, MoneyGram, and Western Union all have different rules for credit cards — and most of those rules amount to "we do not take them."
Some sellers also see credit card purchases for money orders as a sign of financial distress or potential fraud, since most people who need a money order have other payment methods available.
What happens if you use a credit card anyway
If you find a seller willing to take your credit card for a money order, your card issuer will almost certainly classify the transaction as a cash advance, not a regular purchase. This distinction matters because cash advances carry different fees and interest rates than normal spending.
A cash advance fee is typically 3 to 5 percent of the amount you withdraw or spend, with a minimum fee of $5 to $10. On a $500 money order, that could be $15 to $25 in fees alone. Some cards charge a flat fee instead of a percentage.
More importantly, cash advances do not get a grace period. Interest starts accruing the day of the transaction, usually at a higher rate than your regular purchase APR. While a regular purchase might have a 21-day grace period before interest kicks in, a cash advance starts charging interest when ready. This means you pay interest from day one, even if you pay off the balance in full at the end of the month.
Using an ATM to get cash for a money order
The most practical workaround is to withdraw cash from an ATM using your credit card, then use that cash to buy the money order. This still triggers a cash advance fee and interest rate, but at least you know exactly what you are paying for and when.
When you use a credit card at an ATM, you will see the cash advance fee displayed before you complete the transaction. You can decide whether to proceed or try another method. The fee is usually the same percentage or flat amount whether you withdraw $100 or $500, so larger withdrawals are slightly more efficient.
After you withdraw the cash, you can walk into any post office, bank, grocery store, or check-cashing outlet and buy the money order with no additional fees. The only cost is the cash advance fee you already paid.
When Western Union or banks might accept credit cards
Some Western Union locations, particularly those inside grocery stores or pharmacies, may accept credit cards for money order purchases. Policies vary by location and by the specific franchise agreement. The only way to know is to call ahead or ask in person.
Larger banks sometimes allow credit card purchases for money orders at the teller window, though this is becoming less common. Community banks and credit unions are more likely to have this option than national chains, but again, it depends on their internal policy.
Even if a seller accepts your credit card, your card issuer may still decline the transaction or flag it as a cash advance. Some card issuers block credit card purchases for money orders entirely as a fraud prevention measure. You will not know until you try.
Alternatives to using a credit card
If you do not have cash or a debit card, consider whether you actually need a money order. Money orders are useful when you need to send money to someone who does not have a bank account, or when the recipient needs a may provide payment. But for most everyday transactions, there are cheaper alternatives.
A bank transfer or ACH payment costs nothing and works when ready if both parties have bank accounts. Peer-to-peer payment apps like Venmo, PayPal, or Cash App let you send money with a credit card and no cash advance fees, though you may pay a small transaction fee. A personal check costs only the price of a checkbook and works anywhere a money order would.
If you need to send money internationally, a wire transfer through your bank is more expensive than a money order but more find. If you need the money order for a specific reason — paying rent, posting bail, or sending money to someone without a bank account — those are the cases where the cash advance fee might be worth it.
How to minimize the cost if you must use a credit card
If you have no other option, here is how to keep the damage as low as possible. First, call your card issuer before you attempt the transaction and ask whether they classify money order purchases as cash advances and what the fee will be. Some cards have different rates for different types of cash advances.
Second, use the card with the lowest cash advance fee you have access to. If one card charges 3 percent and another charges 5 percent, the difference adds up quickly on larger amounts.
Third, pay off the cash advance as soon as possible. Since interest starts when ready, every day you carry the balance costs you money. If you can pay it back within a week, the interest charge will be minimal. If you carry it for a month, the interest will be substantial.
Finally, consider whether you can borrow cash from a friend or family member instead. A short-term loan with no interest is always cheaper than a credit card cash advance, even if you have to buy them lunch as thanks.
Frequently Asked Questions
Can I use a credit card at the post office to buy a money order?
No. The U.S. Postal Service does not accept credit cards for money order purchases. You must pay with cash, a debit card, or a traveler's check. If you only have a credit card, you will need to withdraw cash from an ATM first.
Will my credit card issuer block a money order purchase?
It depends on your card and issuer. Some card issuers block money order transactions entirely as a fraud prevention measure. Others allow them but classify them as cash advances. The only way to know is to try the transaction or call your card issuer beforehand.
Is the cash advance fee the same as the money order fee?
No. The cash advance fee is charged by your credit card issuer, not by the money order seller. The money order itself has its own fee, which is separate. If you buy a $500 money order with a $1.50 fee and pay with a credit card that charges a 3 percent cash advance fee, you pay both: $15 in cash advance fees plus $1.50 for the money order.
What if I need a money order urgently and do not have time to get cash?
Call ahead to Western Union locations or your bank to ask if they accept credit cards for money orders. Some do, though it is not may provide. If none in your area accept credit cards, find an ATM and withdraw cash, which usually takes less than five minutes.
Is there a limit to how much I can spend on a money order with a credit card?
Money orders themselves have limits — typically $1,000 per order at the post office, though Western Union and other sellers may have different caps. Your credit card's cash advance limit is separate and may be lower than your regular credit limit. Check your card's terms or call your issuer to find out your cash advance limit.
