When you need a payment method that is safer than cash and more reliable than a personal check, consider using a money order.
It is a prepaid payment instrument guaranteed by a bank, post office, or similar institution. You pay the full amount upfront when purchasing it, so it will never bounce like a personal check, protecting the recipient’s interests.
You can use it to pay bills or send personal remittances. For those without bank accounts, it is an important payment tool, with data showing that approximately 3.2% of unbanked individuals use this method to make payments.
Understanding how money orders work and their advantages and disadvantages can help you decide if it is the right payment option for you.
A money order is essentially a prepaid paper payment instrument. Unlike a personal check, you must pay the full amount in cash or with a debit card when purchasing it, meaning the funds are 100% guaranteed with zero risk of bouncing for the recipient.
To help you clearly understand the differences from other payment methods, refer to the table below:
| Feature | Personal Check | Cashier’s Check | Money Order |
|---|---|---|---|
| Funding Source | Personal bank account | Bank’s own account | Prepaid cash/debit card |
| Fund Guarantee | No guarantee, may bounce | Guaranteed | Guaranteed |
| Issuer | Individual | Bank | Post office, retailers, etc. |
| Per-Item Limit | No limit | No limit | Usually under $1,000 |
Despite being a traditional payment method, the advantages of money orders remain very clear:
Of course, money orders also have unavoidable drawbacks:
In contrast, modern digital payment tools address these pain points. For example, platforms like Biyapay support instant global transfers with much higher limits than traditional money orders and more competitive fees, offering a more efficient and cost-effective option for cross-border payments.

Once you decide to use a money order, the next step is to learn how to purchase and fill it out correctly. The process is straightforward, but every detail is critical as it directly affects whether your funds reach the recipient safely.
You can buy money orders at many locations, including post offices, major retail stores, and banks. Fees and limits vary by channel — choosing the best one can save you money.
The table below clearly compares fees and limits at several common purchase points:
| Purchase Channel | Fee | Maximum Per Order |
|---|---|---|
| Walmart | Usually under $1.00 | $1,000 |
| USPS | $2.35 (up to $500) / $2.55 ($500.01–$1,000) | $1,000 (domestic) |
| 7-Eleven | Varies by location, typically 1–3% | $500 |
| MoneyGram | About $1.25 | $500 |
| Banks (e.g., Chase, Bank of America) | Usually $5.00 | $1,000 |
Important tip: Payment methods When buying a money order, you can usually only use cash or a debit card. Most issuers do not accept credit cards. This is because credit card companies treat such transactions as “cash advances,” which trigger high fees and interest that starts accruing immediately — very costly.
If you need to pay more than $1,000, you must purchase multiple money orders. Also note that under U.S. law, if you buy money orders worth $3,000 or more in one day, the issuer must verify and record your identity.
In comparison, digital payment platforms like Biyapay offer a more modern solution. You can make instant global transfers with limits far exceeding a single money order’s $1,000 cap and more competitive fee structures, providing a more efficient and economical option for cross-border payments.
You must be extremely careful when filling out a money order, as any error can invalidate it. Here are the detailed steps:
Never leave this field blank! If you lose a blank-payee money order, anyone who finds it can fill in their own name and cash it — your money would be irretrievable.
Remember: Do not sign on the back — the back is for the recipient to endorse when cashing.
What if you make a mistake while filling? You cannot alter a money order — any changes will void it. If you err, take the incorrect money order and receipt back to the purchase location for a refund or replacement. There may be a small fee, but this is the safest way to protect your funds.

When you receive a money order, knowing how to cash it safely and understanding its expiration and tracking options is the final step to securing your funds.
Cashing a money order is simple. First, sign the back — this is called “endorsement.” Once signed, you can cash it.
You can cash a money order at several places:
Cashing tip Wherever you go, bring valid photo ID, such as a driver’s license or passport. Non-account banks may charge a fee or refuse service.
When using or receiving money orders, note these key points to avoid issues.
| Issuer | Expiration Policy | Notes |
|---|---|---|
| USPS | Never expires | No fees for inactivity, but may become unclaimed property. |
| Western Union / MoneyGram | Never expires | Fees typically start 1–3 years after purchase, deducted from principal. |
| Banks | Usually never expires | Policies vary; some charge inactivity fees. |
If left too long (e.g., over 3–7 years), funds may be turned over to the state as unclaimed property. Reclaiming then requires applying to the state — a complex process.
In summary, a money order is a safe and reliable traditional payment method. Despite growing digital payments, it retains unique value in specific scenarios. If you lack a bank account or need to mail bill payments, it offers convenience. It is also much safer than mailing cash.
Its core advantages are:
- Prepaid guarantee: Funds are assured and will never bounce.
- Trackability: Each has a receipt and serial number — lost ones can be tracked or replaced.
These features make it a trustworthy choice for small payments.
You will have great difficulty tracking or requesting a refund. The receipt is the only proof of payment with the tracking number. Always store it securely until you confirm the recipient has cashed it.
Yes, but only if it has not been cashed. Take the receipt back to the original purchase location to request cancellation. This usually involves a fee and may take time to receive the refund.
Use the tracking number on the receipt to check. Most issuers (e.g., USPS, Western Union) offer online or phone inquiry services. This lets you confirm whether the money order has been cashed.
