Understanding money order limits helps you plan payments and avoid unnecessary trips back to the issuing location. The maximum money order limit varies by provider — the U.S. Postal Service caps domestic money orders at $1,000 per money order, while other providers like Western Union and MoneyGram have their own limits and fee schedules. If you need to send more than a single money order allows, you can purchase multiple money orders, though anti-money laundering rules impose identification and reporting requirements at certain thresholds. This guide covers the main providers, their limits, and the compliance rules you should know.
USPS Money Order Limits
The U.S. Postal Service is one of the most widely used money order providers in the United States. As of 2026, the USPS issues domestic money orders up to a maximum of $1,000 per money order. There is no stated limit on how many money orders you can purchase at one time, but anti-money laundering rules may require identification and trigger reporting if total purchases reach or exceed $3,000 in a single transaction.
For international money orders, the USPS maximum is $700 per money order, and availability is limited to certain countries. Fees for USPS money orders are $2.35 for amounts up to $500 and $3.40 for amounts from $500.01 to $1,000 as of 2026. Fees are subject to change — verify the current fee at your local post office or at usps.com before purchasing. Before buying a money order, it also helps to know how to fill out a money order correctly so it is accepted without issues.
Western Union and MoneyGram Limits
Western Union and MoneyGram both offer money order services, though their limits and availability may vary by location and state regulations. Western Union money orders are typically limited to $500 per money order at most retail locations, while MoneyGram money orders are commonly capped at $1,000 per money order.
Both companies may adjust limits based on the retailer, the state, and the payment method used. Fees and limits at third-party retailers (such as grocery stores or pharmacies) may differ from those at Western Union or MoneyGram locations. Contact the specific provider or retailer to confirm current limits and fees before making a trip. If you frequently need to send larger sums, understanding how long an ACH transfer takes may help you evaluate whether a bank transfer is a more practical alternative.
Anti-Money Laundering Rules and Identification Requirements
Federal anti-money laundering (AML) regulations require money order sellers to collect identification from customers who purchase $3,000 or more in money orders in a single transaction or in related transactions, as enforced by FinCEN under the Bank Secrecy Act.
Sellers are also required to file a Currency Transaction Report (CTR) for cash transactions — including money order purchases — that exceed $10,000 in a single business day. Structuring purchases across multiple days specifically to avoid the $10,000 reporting threshold is illegal under the BSA, regardless of whether the underlying funds are from lawful sources. These rules apply regardless of which provider you use, and it is important to understand them before attempting large transactions.
What Identification Is Required?
When identification is required for a money order purchase of $3,000 or more, you may be asked to provide a government-issued photo ID such as a driver's license, state ID card, or passport, per FinCEN recordkeeping requirements. The seller is required to record your name, address, and ID number. This information may be retained for five years under BSA recordkeeping rules. For context on how long financial records are typically kept, see our guide on how long to keep bank statements.
Sending Amounts Larger Than a Single Money Order Limit
If you need to send more than $1,000, you can purchase multiple money orders to cover the total amount. For example, a payment of $2,500 could be covered by two $1,000 money orders and one $500 money order, subject to identification requirements at the $3,000 threshold.
For large payments, it may be more practical to use a cashier's check from your bank, an ACH bank transfer, or a wire transfer. These methods typically allow much higher transaction amounts and may be faster and more secure for large sums. The CFPB's guide to sending money explains the tradeoffs between payment methods. You may also want to explore how to get a certified check from your bank as a guaranteed alternative to a money order for large payments. Before sending, make sure you know how to fill out a deposit slip so you can properly deposit any money orders you receive in return. For very large transfers where cash is involved, understanding how to void a check correctly is also useful if a check accompanies your transaction.
How to Use a Money Order Safely
Always fill in the payee name immediately when you purchase a money order. A blank money order can be cashed by anyone who finds or steals it. Keep your purchase receipt — it contains the serial number you need to request a refund or trace the money order if it is lost or stolen, as the USPS recommends.
Be aware that money order scams are common. The CFPB warns consumers never to accept a money order for more than the amount owed and then wire the excess back — this is a well-known fraud scheme in which the original money order turns out to be counterfeit. Also keep in mind that money orders have an expiration timeline — review our guide on how long a money order is good for before issuing one to someone else.
Frequently Asked Questions
What is the maximum amount for a USPS money order?
The USPS issues domestic money orders up to $1,000 per money order and international money orders up to $700 per money order as of 2026. If you need to send more than $1,000, you can purchase multiple money orders, though purchases of $3,000 or more in a single transaction may require you to show a government-issued photo ID under federal AML rules.
Do money orders expire?
USPS money orders do not expire, but a fee may be deducted if the money order is not cashed within one to three years, depending on the state and the specific terms. Money orders from other providers, such as Western Union or MoneyGram, may also charge dormancy fees over time — check the terms on the money order itself before issuing one. Our guide on how long money orders are good for covers the expiration rules for each major provider.
Can I cancel a money order if I made a mistake?
Yes, but the process varies by provider. For a USPS money order, you must complete a money order inquiry form at a post office and pay a processing fee. You will need your original receipt with the serial number. Western Union and MoneyGram have similar refund request processes — contact the provider directly with your purchase receipt. Understanding how to fill out a money order correctly from the start can help you avoid errors that require cancellation. Similarly, knowing how to write a check accurately applies the same principle — precision upfront avoids costly corrections later.
Is a money order safer than a personal check?
Money orders are generally considered safer than personal checks because they are prepaid and guaranteed by the issuer — the recipient does not need to worry about the funds bouncing. However, counterfeit money orders are a common fraud tool. Businesses and individuals should verify a money order at the issuer before treating it as cleared funds. For large transactions where a guaranteed payment is essential, consider getting a certified check from your bank instead. If you receive a money order and want to deposit it, learning how to endorse a check explains the same back-of-instrument signing process that also applies to depositing money orders.
