Can You Buy Money Orders With a Credit Card? Here's What You Need to Know 💳

The short answer: it depends on where you're buying the money order and what the issuer allows. Some vendors accept credit cards, while many don't. And even when they do, paying for a money order with credit carries financial trade-offs worth understanding.

How Money Orders Work

A money order is a prepaid financial instrument—essentially a guaranteed payment method issued by banks, post offices, retailers, and other providers. You pay the face amount plus a fee upfront, and the recipient can cash or deposit it. Because the money is already in the issuer's hands, there's no credit risk involved.

This matters because it shapes which payment methods vendors will accept.

When Credit Cards Are Accepted

Some retailers and money order providers do accept credit cards, particularly at:

• Retail chains (Walmart, grocery stores, drugstores) where money orders are offered alongside other services
• Western Union and similar wire transfer services, which may accept cards for certain transactions
• Online money order platforms (though these are less common and should be vetted carefully)

However, acceptance varies widely by location and provider. Even within the same chain, policies can differ by branch or state.

When Credit Cards Are Declined

Many issuers—including the U.S. Postal Service—explicitly do not accept credit cards for money orders. They may accept:

• Cash
• Debit cards
• Checks
• In-person bank transfers

The reasoning is straightforward: issuing a money order through a credit card creates a cash advance, which carries different risk and regulatory treatment than a regular purchase.

The Financial Impact of Using Credit for Money Orders

If you do use a credit card, understand what you're actually doing:

Cash advance vs. regular purchase: Many credit card issuers treat money order purchases as cash advances, not standard purchases. This distinction means:

• Higher fees: Cash advance fees are typically a flat amount or percentage (check your card terms), separate from purchase fees
• Different APR: Cash advances often carry a higher interest rate than regular purchases, with interest accruing immediately—no grace period
• Credit scoring: Some card issuers report cash advances differently to credit bureaus

How to know your card's terms:

Review your cardholder agreement or call your issuer. They'll tell you whether money orders code as cash advances and what fees apply. Some newer or specialized cards have different policies, but most traditional cards do treat them this way.

Why You Might Consider Alternatives

Given these costs, evaluate whether a credit card is the right payment method:

• If you have cash or a debit card, use those instead—you'll avoid fees and interest entirely
• If you need to build credit, a money order purchase via credit doesn't help (cash advances don't count toward purchase history in the same way)
• If you're short on funds, the added cost of a cash advance might signal that a money order isn't the right tool for this situation

What Variables Affect Your Decision

The Bottom Line

You can sometimes buy money orders with a credit card, but it's often not the best financial choice. Most providers don't accept them, and those that do may treat the transaction as a costly cash advance. Before attempting to pay with plastic, confirm your vendor accepts it, verify your card's terms, and compare the total cost against using cash or a debit card. In most cases, those alternatives are cheaper and simpler.
