Most places will not sell you a money order with a credit card
Money order sellers — post offices, grocery stores, check-cashing outlets, and wire transfer services — treat credit cards differently from cash or debit cards. The vast majority require cash, a debit card, or a bank account transfer. A few will accept a credit card, but those exceptions are rare and come with restrictions.
The reason is straightforward: a money order is a may provide payment instrument. When you buy one, the seller collects your money upfront and guarantees it to the recipient. If you pay with a credit card, the seller takes on the risk that you will dispute the charge later, leaving them holding a money order they have already issued. That risk is why most refuse credit cards entirely.
Key Takeaways
- Post offices, Walmart, grocery stores, and most check-cashing outlets do not accept credit cards for money orders; they require cash or a debit card.
- Western Union and MoneyGram occasionally accept credit cards at certain locations, but fees are higher and you should call ahead to confirm.
- If you do not have cash or a debit card, you can withdraw cash from an ATM using your credit card, though this incurs a cash advance fee and interest.
- Some credit card issuers block money order purchases as cash advances, which means interest starts accruing immediately even if you pay the full balance at the end of the month.
Where you might find credit card acceptance
Western Union and MoneyGram, the two largest money transfer networks, have more flexibility than traditional money order sellers. Some Western Union locations — particularly those inside grocery stores or pharmacies — will accept a credit card. MoneyGram has similar pockets of acceptance, though it is inconsistent by location.
Even when these services do accept credit cards, the transaction is often coded as a cash advance rather than a purchase. That distinction matters: a cash advance typically carries a higher interest rate than regular purchases, and interest begins accruing immediately. You do not get a grace period the way you do with regular credit card purchases.
Before you go to a Western Union or MoneyGram location, call ahead or check their website for that specific branch. Acceptance varies widely, and showing up without confirmation wastes time.
Why your credit card issuer might block the transaction
Even if a money order seller accepts credit cards, your card issuer may decline the transaction or reclassify it as a cash advance. Many credit card companies flag money orders, wire transfers, and similar transactions as cash-like products and treat them as cash advances automatically.
When your issuer codes a transaction as a cash advance, several things happen at once. The interest rate jumps — often to 25% or higher, compared to a standard purchase rate of 15% to 20%. Interest accrues from the day of the transaction, not from the end of the billing cycle. And you typically cannot earn rewards points on the transaction.
You can call your card issuer before attempting a purchase to ask whether they will allow it and how they will code it. Some issuers are more permissive than others, but most will warn you that they treat money orders as cash advances.
Using an ATM to get cash instead
If you need a money order but do not have cash or a debit card, the most straightforward option is to withdraw cash from an ATM using your credit card. This is a cash advance, and it will incur a fee — typically 3% to 5% of the amount withdrawn, with a minimum fee of $2 to $5. Interest also starts accruing immediately at the cash advance rate.
The math is worth checking before you proceed. If you need $500 for a money order, a 5% ATM fee costs $25 plus interest. If you carry that balance for a month at 25% annual interest, you will pay roughly $10 more in interest. That is $35 total to get $500 in cash. For smaller amounts, the fee may be a larger percentage of what you are withdrawing.
Once you have the cash, you can walk into any post office, grocery store, or check-cashing outlet and buy a money order without any additional friction. The money order itself costs between $1 and $3 depending on the amount and the seller.
Debit cards and prepaid cards as alternatives
If you have access to a debit card linked to a bank account, use that instead. Debit cards are accepted everywhere that takes credit cards for money orders, and they do not trigger cash advance fees or interest charges. The transaction is treated as a regular debit from your account.
Prepaid cards — including reloadable gift cards and prepaid Visa or Mastercard products — are also accepted at most money order sellers. If you have a prepaid card with a balance, it functions like a debit card and avoids the cash advance problem entirely.
If you do not have either a debit card or a prepaid card, opening a basic checking account at a bank or credit union is faster and cheaper than repeatedly paying ATM fees and cash advance interest. Many banks offer accounts with no monthly fee and no minimum balance.
What happens if you successfully charge a money order
If your credit card issuer does allow the transaction and does not code it as a cash advance, the charge will appear on your statement as a regular purchase. You will earn rewards points if your card offers them. Interest will not accrue if you pay the full balance by the due date.
However, this scenario is uncommon. Most issuers either decline the transaction outright or reclassify it as a cash advance. Even if the transaction goes through as a purchase, you are paying interest on money that is not yours — you are borrowing to buy a may provide payment instrument, which is an expensive way to solve a cash flow problem.
If you find yourself in this position regularly, it signals that you need a debit card or a different payment method, not a workaround with your credit card.
Money order limits and what to do if you need more
A single money order is typically capped at $1,000, though some sellers allow up to $1,500. If you need to send more than that, you will need to buy multiple money orders. This is allowed, but each one costs a separate fee — usually $1 to $3 per order.
If you are sending a large amount and do not have a debit card, buying multiple money orders with credit card cash advances becomes very expensive. Each ATM withdrawal incurs a separate fee, and each money order purchase incurs a separate fee. For amounts over $5,000, a bank wire transfer or a check may be cheaper and faster, even if you have to pay for a cashier's check.
Frequently Asked Questions
Can I buy a money order with a credit card at Walmart?
Walmart does not accept credit cards for money orders. You must pay with cash, a debit card, or a PIN-based prepaid card. Walmart money orders cost $0.88 for amounts up to $1,000.
Will my credit card issuer tell me if they treat money orders as cash advances?
Not automatically. You have to call and ask. Your cardholder agreement may mention it, but most people do not read that section. Calling your issuer before you attempt a purchase takes five minutes and saves you from surprise fees.
Is there a difference between a money order and a cashier's check?
Yes. A cashier's check is issued by a bank and typically costs $5 to $15. A money order is issued by a post office, grocery store, or wire service and costs $1 to $3. Cashier's checks are larger and more formal; money orders are for smaller amounts. Both are may provide payments, but banks are more likely to accept credit cards for cashier's checks than retailers are for money orders.
What if I need a money order right now and do not have cash?
Find an ATM and withdraw cash using your credit card, then buy the money order with that cash. Yes, you will pay an ATM fee and interest, but it is faster than trying to find a location that accepts credit cards for money orders directly. For future reference, get a debit card to avoid this problem.
Can I use a credit card to buy a money order online?
Some online money transfer services accept credit cards, but they are not traditional money orders — they are digital transfers. Services like PayPal, Venmo, and Square Cash work differently and may have their own fees. If you specifically need a physical money order, you have to buy it in person at a retail location.
