Can You Pay a Money Order with a Credit Card?

Can You Pay a Money Order with a Credit Card?

You generally cannot pay for a money order with a credit card. The major retailers that sell money orders — including the U.S. Postal Service, Walmart, Western Union, and MoneyGram — treat the purchase as a cash-equivalent transaction and require cash, debit cards, or sometimes traveler's checks. A credit card is almost never an accepted form of payment at the point of sale.

Why Retailers Restrict Credit Cards for Money Orders

Money orders function like cash, and credit card purchases carry interchange fees that retailers must absorb. More importantly, credit card networks classify money orders as cash-equivalent products, which means a credit card purchase can be treated as a cash advance. That triggers immediate interest charges, often higher than the standard APR, and usually starts accruing the day of the transaction.

Cash Advance Fees and Interest

When a credit card issuer treats a money order as a cash advance, the cardholder typically faces a fee of 3% to 5% of the transaction amount or a flat dollar amount, whichever is greater. The interest rate for cash advances is often higher than the rate for purchases, and there is no grace period. This makes buying a money order with a credit card an expensive option even if a retailer were willing to process it.

Where You Might Still Use a Credit Card

A few online platforms and financial service providers allow you to buy a money order using a credit card indirectly, but these are rare and often come with significant fees. Some prepaid card services or third-party payment platforms may facilitate the transaction, but the cost and risk usually outweigh the convenience. Before proceeding, check your card issuer's terms to confirm whether the purchase will be coded as a cash advance.

Better Alternatives to Consider

If you need a money order and do not have cash on hand, consider these options:

• Use a debit card linked to a checking account at most retail locations.
• Withdraw cash from an ATM and purchase the money order with cash.
• Use a bank account transfer or bill pay service if the recipient accepts electronic payments.
• Request a cashier's check from your bank, which is often funded directly from your account.

The most reliable path is to use cash or a debit card. The fee structure is transparent, the transaction processes immediately, and you avoid the steep costs and credit implications that come with treating a money order as a cash advance on a credit card.
