Using a credit card to buy a money order sounds simple: you’re just swapping one kind of payment for another. In practice, it’s more complicated — and often more expensive — than people expect.
This FAQ walks through how it works, when it’s allowed, and what you’ll want to check before you try it.
Sometimes, but not always.
Whether you can use a credit card to buy a money order depends on:
Even when a location allows it, paying for a money order with a credit card is usually not the cheapest or most straightforward option.
Before getting into details, it helps to be clear on a few terms:
Money order: A prepaid paper payment instrument. You pay upfront (usually with cash, debit, or another verified source), and the money order can be made out to a person or business. It’s often used when someone wants a guaranteed form of payment or doesn’t accept personal checks.
Credit card: A revolving line of credit from a card issuer or bank. When you pay for something with a credit card, you’re borrowing money and agreeing to pay it back, usually with interest if you don’t pay off the balance by the due date.
Cash advance: A way of borrowing cash on a credit card. This can be via:
Cash advances usually come with:
Money orders purchased with a credit card are often placed in this “cash-like” bucket.
Different places have different rules. Some common spots:
Many national postal services do not allow credit cards for purchasing money orders. They may limit you to:
Variables here:
If you’re thinking of using a credit card at a post office, you’d typically need to confirm in person or on their website whether credit is allowed for money orders.
Banks and credit unions sell money orders (or similar instruments like cashier’s checks), but many:
A few may allow money orders with a credit card, but they might:
Policies vary by institution, and sometimes even by account type or branch.
Some large retailers and supermarket chains sell money orders at their customer service desk. Their rules about using a credit card can differ:
You won’t know how your credit card issuer will treat the transaction just by the store’s sign — the store’s rule (“we take credit cards”) and the issuer’s rule (“we treat this as a cash advance”) are two separate things.
Places that specialize in money transfers, check cashing, or prepaid cards often:
These locations sometimes cost more overall compared with banks or grocery stores, but may offer more flexible hours or limits.
From the bank’s perspective, a money order is often seen as essentially turning your credit line into cash. Even though you’re not leaving with physical bills, you’re:
Because of that, card networks and issuers commonly classify money orders with other “cash-like” transactions, such as:
Once tagged as a cash advance, the transaction is subject to:
The exact treatment depends on your specific card’s terms.
If your location and card both allow the transaction, consider:
Common types of potential charges:
Cash advance fee
Often calculated as a percentage of the amount, sometimes with a minimum dollar amount.
This is on top of the money order fee charged by the seller.
Higher interest rate
Cash advances frequently carry a higher APR than everyday purchases.
No grace period
With typical purchases, if you pay your full statement balance by the due date, you might avoid interest.
With cash advances, interest may start the day the transaction posts.
Most money order vendors charge:
The fee structure can vary widely by:
These fees apply regardless of how you pay, but they add to the overall cost if you’re also paying credit card fees and interest.
Buying a money order with a credit card increases your card balance and can affect:
A higher utilization ratio can affect your credit score, especially if kept high over time. The impact varies by person, existing balances, income, and how quickly the debt is repaid.
Credit cards offer dispute rights for unauthorized or faulty purchases. However, when you turn that credit into a money order and hand the money order to someone else:
The protections are not as straightforward as disputing a normal card purchase at a store.
People consider this for different reasons. Common ones:
Paying someone who doesn’t take cards
For example, a landlord, a small contractor, or an organization that only accepts money orders or cashier’s checks.
Covering a bill when cash is tight
Using a credit card to buy a money order can feel like a way to “bridge the gap” until your next paycheck.
Trying to earn rewards points or cash back
Some hope that buying a money order counts as a “purchase” and earns rewards, which they might then use to offset costs.
Needing a paper trail or mailing payment
Money orders provide a record and can be mailed, which appeals to people who don’t want to send cash.
Each of these reasons comes with trade-offs in fees, debt, and complexity, which can be more or less important depending on your situation.
Here’s a simplified overview of what you might run into:
| Scenario | Store/bank likely to allow credit card? | Card issuer likely to treat as cash advance? |
|---|---|---|
| Buying a money order at a big grocery chain | Sometimes yes, sometimes no | Frequently yes |
| Buying at a national post office | Often no | N/A (credit not accepted) |
| Buying at your own bank branch with your credit card | Often no (debit/cash only) | Likely yes if allowed |
| Buying at a check-cashing or money transfer outlet | Mixed; many prefer cash/debit | Often yes if credit is accepted |
This table is general — individual policies can differ by country, bank, card network, and even specific store location.
If you’re deciding whether to buy a money order with a credit card, it helps to walk through a few points:
Does the place you’re buying from accept credit cards for money orders?
How does your card issuer classify money orders?
What’s the total cost to you? Consider:
Are there lower-cost alternatives in your situation?
Without recommending a specific path, common alternatives people explore include:
Which option is workable depends on what accounts you have, what the recipient will accept, and your own cash-flow and fee tolerance.
People in different situations may weigh the pros and cons in different ways:
Someone with limited cash but open credit might see this as a short-term bridge, but faces the risk of:
Someone focused on earning rewards might hope to gain points, but:
Someone without a bank account might rely heavily on money orders, and:
Someone trying to avoid bounced checks might prefer a money order, but:
In every case, the trade-off is between convenience and access on one side, and fees, interest, and debt risk on the other.
You don’t need anyone else to decide for you, but you do need a clear picture of:
Your card’s rules
The seller’s rules
Your own situation
Once you know these pieces, you can line up the total cost, the risks, and the alternatives, and decide whether paying for a money order with a credit card makes sense for your circumstances.
