Paying for a money order with a credit card is possible in some situations, blocked in others, and often more expensive than people expect. The rules depend a lot on where you buy the money order and how your credit card treats the transaction.
This FAQ walks through the key points so you understand the trade-offs before you swipe.
A money order is a prepaid paper payment — like a check that’s already funded. You pay the issuer (post office, store, bank), and they issue the money order to your recipient.
When you try to pay for a money order with a credit card, there are three main possibilities:
Not allowed at all
Many major issuers simply do not accept credit cards for buying money orders.
Allowed, but treated as a cash advance
Some places (or card issuers) allow it, but your card processes it as a cash advance, not as a regular purchase.
Allowed and treated as a purchase (less common)
In some limited cases, you may find a location or issuer that treats it like a normal purchase. This is the exception, not the rule.
Which of these applies depends on:
From the issuer’s point of view, a money order is a lot like cash. You’re converting your available credit into a guaranteed payment instrument.
Because of that, many sellers:
They do this to:
So before you even think about how your card treats the transaction, the first gate is simple:
This can vary even between branches of the same chain, so local policy matters.
This is the part that surprises most people.
Even if the seller runs it as a normal card transaction, your card issuer decides how to classify it. In many cases, buying a money order is coded as a cash-like transaction, which usually means cash advance.
| Feature | Regular Purchase | Cash Advance (Typical) |
|---|---|---|
| How it’s treated | Everyday spending | Cash-equivalent/“cash-like” transaction |
| Interest start date | Often has a grace period | Often starts accruing interest immediately |
| Interest rate | Standard purchase APR | Often higher APR |
| Extra fees | Usually no “per transaction” fee | Often a cash advance fee |
| Rewards (points/cash back) | Usually earn rewards | Often no rewards on cash advances |
| Credit limit used | Purchase credit limit | Often limited by cash advance limit |
Because money orders are considered cash-equivalents, they often fall into the cash advance bucket. But not always — and that uncertainty is why it’s important to know your issuer’s rules, not rely on assumptions.
Different places have different policies. Broadly, you’ll see three common sources:
Many national postal services:
If they do allow cards, they may:
Because these rules are set by the postal organization, they can differ from one country to another and sometimes change over time.
Many big chains sell money orders through services like Western Union or MoneyGram.
Common patterns:
Policies vary by:
You often have to ask at the customer service desk or check posted signs to know for sure.
Banks and credit unions often sell money orders or cashier’s checks to their customers.
Common traits:
Even if you could use a credit card at a bank counter, banks are especially likely to code that as a cash advance under their own rules.
If you do find a way to pay for a money order with a credit card, here are the main cost factors to watch:
Many credit cards charge a cash advance fee when you:
This fee is often:
The exact structure depends on your card’s agreement.
For many cards:
That means even if you plan to pay your statement in full, you might still pay interest from the day you buy the money order until the day the balance is paid down.
Many issuers exclude cash advances from earning rewards:
So if someone is thinking “I’ll buy a money order on my credit card to earn rewards and pay a bill,” they may:
Cash advances usually draw from a separate cash advance limit, which can be:
Using a large share of your available credit (purchase or cash advance) can affect:
People think about using credit cards for money orders for different reasons. Each has its own pros and cons.
Some landlords, utilities, or individuals want money orders instead of checks or electronic payments.

If the answer to “Do you accept credit cards?” is no, that’s the end of the road there.

Within the broader world of card payments and account access, using a credit card to buy a money order is a way of:
Because it often behaves like a cash advance, it’s closely tied to how your issuer lets you access your credit beyond ordinary shopping. That’s why the rules and costs are usually different, and why policies can be stricter.
Whether paying for a money order with a credit card makes sense (or is even possible) depends on:
If you line up those pieces — store policy, card terms, potential costs, and your other options — you’ll have a clear view of whether this path fits your situation, even if the answer is different for someone else.
