What is the main difference between a money order and a cashier's check?

A money order is purchased with cash at a post office, Walmart, or grocery store and is capped at $1,000. A cashier's check is issued by a bank, can be for any amount, and is generally required for large transactions like real estate closings and vehicle purchases.

Which is safer: a money order or a cashier's check?

Both are considered guaranteed funds, but cashier's checks are backed directly by a bank and harder to counterfeit. Money orders are more susceptible to fraud. For large amounts, a cashier's check — or wire transfer — is safer.

Can I get a money order replaced if I lose it?

Yes, but it is slow. USPS money orders can be replaced by filing Form 6401 with ID and a $7.45 fee; processing takes 30–60 days. Keep your receipt as proof of purchase. See our guide on lost money orders for the full process.

Do I need a bank account to get a money order?

No. Money orders are purchased with cash or a debit card at the post office, Walmart, Western Union, and many grocery stores. A cashier's check requires a bank account at the issuing bank.

How long is a cashier's check good for?

Most cashier's checks expire after 90 days to 1 year, depending on the bank. A money order is typically valid for 1–3 years. After expiration, fees may apply or the issuer will void the instrument — contact the bank or issuer to arrange a replacement.

Money Order vs. Cashier's Check 2026 — Which One Should You Use?

A money order is the right choice for payments under $1,000 when you don’t have a bank account. A cashier’s check is better for large or high-stakes transactions — real estate closings, vehicle purchases, security deposits — because it’s issued by a bank and harder to dispute or counterfeit. Both are considered guaranteed funds; the difference is cost, limits, and accessibility.

Quick comparison:

Feature	Money Order	Cashier’s Check
Maximum amount	$1,000 (USPS), $500–$1,000 (others)	No limit
Bank account required?	No	Yes (usually)
Where to buy	Post office, Walmart, Western Union	Bank or credit union
Cost	$1–$2	$8–$15
Best for	Rent, small purchases, privacy	Real estate, large purchases
Replacement if lost	30–60 days	Varies by bank

What Is a Money Order?

A money order is a paper payment instrument you purchase with cash (or sometimes a debit card). You pay the face value plus a small fee, fill in the payee name, and it functions like a check — but backed by the issuing institution, not a personal bank account.

Where to buy a money order:

Location	Fee	Maximum
USPS	$2.35 (up to $500), $3.40 ($500.01–$1,000)	$1,000
Walmart	$1 (up to $1,000)	$1,000
Western Union	$1–$2+ (varies by location)	$1,000
MoneyGram (CVS, Walmart)	$1–$2	$1,000
7-Eleven	$1.50	$500

No bank account needed. Just bring cash and a payee name. For step-by-step instructions, see how to fill out a money order.

Money order limitations:

Capped at $1,000 per instrument (though you can buy multiple)
Must be purchased before you know the exact amount (some situations require a certified exact figure)
Replacement is slow if lost or stolen

What Is a Cashier’s Check?

A cashier’s check is issued and guaranteed by a bank. You ask your bank to draw the check from the bank’s own funds — your account is debited immediately, and the bank signs the check as drawer. Because the bank’s creditworthiness backs the check, it is considered as reliable as cash.

How to get a cashier’s check:

Go to your bank (in person or, at some banks, online)
Provide the payee name and exact dollar amount
Pay the check fee ($8–$15 at most banks; free with some premium accounts)
The bank issues the check from its own funds; your account is debited immediately

When you need a cashier’s check:

Real estate closing (the most common requirement)
Vehicle purchase from a private seller
Large security deposits
Paying contractors for large jobs
Any transaction where the recipient specifically requires guaranteed funds

Worked example: You’re buying a used car for $14,500. The seller won’t accept a personal check. You visit your bank and request a cashier’s check for $14,500. Your account is debited the same day, plus a $10 fee. The seller accepts it without hesitation because the bank’s name backs it.

Money Order vs. Cashier’s Check: Which to Choose?

Choose a money order when:

The amount is $1,000 or less
You don’t have a bank account
You want privacy (money orders don’t reveal your account number)
You’re paying rent, a small bill, or shipping payment
You need a payment method accepted widely by individuals and small businesses

Choose a cashier’s check when:

The amount is over $1,000
The recipient specifically requires guaranteed funds
You’re completing a real estate transaction, vehicle purchase, or large deposit
You want a more verifiable, harder to counterfeit instrument
You already have a bank account and the $8–$15 fee is acceptable

When neither is the best option:

Wire transfer — For very large or international transactions, a wire is faster and leaves a verifiable trail. Fees are $15–$35.
Zelle / ACH — For trusted parties, free electronic transfers are faster than either paper instrument.
Personal check — For trusted payees where guaranteed funds are not required, a personal check is free.

Fraud Risks: What to Watch For

Both money orders and cashier’s checks are targets for scams because they appear to represent guaranteed funds.

The common scam: Someone sends you a money order or cashier’s check for more than the amount owed and asks you to refund the difference in cash or gift cards. You deposit the instrument, send the cash — and then the check bounces days later. You lose the cash you sent; the scammer keeps it.

Key rule: Genuine cashier’s checks and money orders do not require you to send money back. If someone sends you one and requests a refund of a portion, do not proceed.

Verify a suspicious cashier’s check by calling the issuing bank directly (look up the number independently — do not use the number printed on the check).

How to Replace a Lost Money Order or Cashier’s Check

Money order (USPS): File Form 6401 at any post office with your receipt and ID. Fee: $7.45. Processing: 30–60 days.

Cashier’s check: Contact your bank. Most require an indemnity bond (an insurance policy covering the bank if the original check is cashed later). Processing: 90 days to 1 year in some cases. See our lost money order guide for the full replacement process.
