Can You Mail Money with USPS? Fees & Security Guide

Yes, you can mail money through USPS — using money orders (the recommended method) or cash with significant limitations. USPS money orders carry a small purchase fee that varies with the amount — see current USPS pricing for the fee schedule. They never expire and include enhanced security features in the redesigned 2026 format. Cash sent through regular mail is insured for only a minimal amount, making money orders the far safer choice for any meaningful transfer.

USPS money orders offer a secure, trackable alternative to mailing cash, with built-in fraud protection, a new QR code for instant status verification, and guaranteed acceptance nationwide. The USPS suite of shipping and payment services has long centered on money orders as the most reliable domestic payment instrument available at any Post Office counter.

In February 2026, USPS introduced newly redesigned money orders featuring a red, white, and blue color scheme with a Pony Express rider watermark. Both the new design and the legacy green money orders remain valid at all Post Offices and financial institutions.

How Much Does a USPS Money Order Cost in 2026?

USPS money order fees are tiered by the dollar amount being sent. The current 2025–2026 fee structure charges a lower flat fee for smaller amounts and a slightly higher flat fee for larger amounts.

You can purchase USPS money orders at any Post Office location using cash, debit card, or traveler’s check. Personal checks and credit cards are not accepted. The maximum amount for a single domestic money order is a set maximum, but you can purchase multiple money orders if you need to send more.

• Q: Do USPS money orders expire? A: No. USPS money orders never expire and do not accrue interest.
• Q: Can I buy multiple money orders? A: Yes. There is no limit on how many money orders you can purchase in a single visit.

What Are the Security Features of USPS Money Orders?

USPS money orders are among the most secure paper payment instruments available. The redesigned 2026 format introduced several upgrades specifically aimed at combating counterfeiting.

Current security features include:

• A watermark image of a Pony Express rider running down the left side
• A second watermark reading “United States Postal Service” on the right side
• An embedded security thread running top to bottom — held to light, it reveals alternating “USPS” text
• A QR code linking directly to the USPS “Check Money Order Status” tool
• The dollar amount imprinted twice on the document
• A red, white, and blue color scheme replacing the previous green design

If you suspect a money order may be counterfeit, contact the U.S. Postal Inspection Service immediately. Warning signs include discoloration, missing security threads, unusually large stated values, or absent QR codes on newer-format orders.

Money orders must be completed at the Post Office counter with the help of a retail associate. Keep the receipt — it is the only way to initiate a replacement if the money order is lost or stolen.

Can You Mail Cash Through USPS?

Mailing cash through USPS is legal but strongly discouraged for larger amounts. Standard domestic mail provides only minimal insurance coverage for cash, meaning anything above that amount is sent entirely at your own risk.

For larger commercial cash transactions, federal regulations require Registered Mail, which provides chain-of-custody tracking and insurance coverage up to a high set limit. Registered Mail is expensive and designed for high-value documents and items — not routine money transfers. Reviewing how USPS insurance works and what it covers helps clarify why cash rarely qualifies for meaningful protection.

Cash sent through regular mail has no tracking and virtually no recovery path if it goes missing. USPS postal inspectors consistently recommend money orders, cashier’s checks, or electronic transfers over mailing cash for any amount worth protecting.

• Q: Is it legal to mail cash? A: Yes, but insurance is capped at a minimal amount for regular mail, and recovery if lost is nearly impossible.
• Q: What’s the maximum cash insurance? A: a minimal amount for standard mail; a much higher limit for Registered Mail service.

How Can You Send Money Internationally Now That USPS Discontinued International Money Orders?

USPS discontinued its international money order program effective October 1, 2024. The inbound service also ended on October 1, 2025, meaning USPS no longer issues or cashes international postal money orders in either direction. If you need to send money abroad, you will need to use an alternative method. Options for using USPS services outside the United States are now limited to physical parcel and mail delivery rather than financial transfers.

Current alternatives for international money transfers include:

• Bank wire transfers — available at most U.S. banks, with fees that vary by bank per transfer
• Online transfer services — platforms such as Wise, Remitly, and Western Union offer competitive exchange rates and faster delivery than mail
• Western Union / MoneyGram money orders — domestic money orders from these providers can sometimes be used for cross-border payments depending on the destination country

The discontinuation reflects a broader shift: electronic transfer services deliver funds faster and more affordably than paper instruments, and volume had declined sharply in the years leading up to the program’s end.

Where Can You Cash USPS Money Orders?

USPS money orders are accepted at a wide range of locations, giving recipients flexible options for accessing the funds.

To cash a money order, the recipient needs valid primary photo ID — a driver’s license or passport — and should sign the money order at the cashing location in front of the service representative, not beforehand.

Cashing locations include:

• Any Post Office location — free with valid ID, the most cost-effective option
• Most banks — typically free for account holders, fees may apply for non-customers
• Grocery stores with money services
• Check-cashing businesses
• Some retail chains

Rural mail carriers may also cash money orders in remote areas if they have sufficient funds on hand, providing added convenience for customers in less-served communities.

How Do You Track and Replace a USPS Money Order?

USPS provides an online Money Orders Application where customers can check the status of a money order using its serial number, Post Office number, and dollar amount. The system shows whether the money order has been cashed and when.

Unlike bank checks, you cannot stop payment on a USPS money order after it is issued. However, lost or stolen money orders can be replaced through a formal inquiry process at any Post Office. If you’re navigating a missing item of a different kind, our guide on what happens when USPS loses your package outlines the recovery steps for parcels.

Replacement requirements:

• Original money order receipt
• Completed inquiry form at a Post Office
• A processing fee
• Up to 30 days to confirm lost/stolen status
• Up to 60 additional days for full investigation and replacement issuance

Damaged money orders can be exchanged at a Post Office by presenting both the damaged money order and the original receipt — no processing fee applies to exchanges.

What’s the Best Way to Send Money Through USPS?

For most needs, a USPS money order is the optimal balance of security, cost, and convenience. It provides tracking, fraud protection, and guaranteed acceptance that cash cannot match, at a fraction of the cost of a wire transfer.

Money orders are most cost-effective for moderate amounts. For smaller amounts, the flat fee represents a larger percentage of the transfer, making electronic alternatives worth considering.

For time-sensitive deliveries, Priority Mail Express can transport a money order overnight at an additional shipping cost. Standard First-Class Mail takes 1–3 business days and costs only the regular postage rate. Knowing how fast USPS delivers across its service levels helps you choose the right combination of speed and cost.

Consider the recipient’s situation when choosing your method. For domestic transfers, USPS money orders remain one of the most reliable and widely accepted paper payment instruments available.

USPS money orders can be cashed for free at any Post Office with valid photo ID. They are also accepted at most banks (free for account holders, fees for non-customers), grocery stores with money services, and check-cashing locations.

Is it safe to mail cash through USPS?

Mailing cash is legal but carries serious risk. Regular mail insures cash for only a minimal amount, and there is no tracking to help recover a lost envelope.
