Does the Post Office Cash Checks? Limits, Fees, and Money Orders

The post office does cash checks, but only a narrow set of them. USPS branches will cash U.S. Treasury checks, USPS commercial checks (including postal salary checks), and domestic postal money orders.¹ Personal checks, private payroll checks, and cashier’s checks are off the table. The common thread across what USPS will handle is that the federal government either issued or guaranteed the funds, which is why the Postal Service can pay on them without operating as a bank.

Checks the Post Office Will Cash

Three instruments qualify at the counter:

Domestic postal money orders, up to a face value of $1,000 each.²
U.S. Treasury checks, such as tax refunds and federal benefit payments, as long as the check is less than one year old.¹
USPS commercial checks, including checks paying postal employees.¹

Only the named payee can cash any of these, and the payee has to be an individual. If a Treasury check, postal money order, or USPS commercial check is made out to a company, nonprofit, government agency, or partnership, the post office cannot cash it. Business-payable instruments have to be deposited at a bank.¹

Checks the Post Office Won’t Cash

Everything outside that short list gets turned away, including some instruments people reasonably assume would qualify:

Personal checks. USPS has no way to verify a private bank account has funds behind the check.
Private payroll checks. A paycheck drawn on a private employer’s bank account is outside USPS authority, even though a USPS payroll check is not.
Cashier’s checks and bank drafts. Prepaid by the issuing bank or not, USPS is not authorized to redeem them.

If your check falls in this group, you will need a bank, a retailer that cashes checks, or a check-cashing store. More on those options at the end.

Cashing a Treasury Check or USPS Salary Check

Bring the check and valid photo identification. A driver’s license, passport, state ID, or military ID works; the clerk can ask for two forms of ID for a Treasury check. If the clerk doesn’t know you personally, expect to be asked. The check has to be less than one year old, and the branch has to have enough cash on hand to pay out the amount.¹

Paper Treasury checks are becoming rarer. Starting September 30, 2025, the federal government began phasing out paper checks for most federal payments and moving recipients to direct deposit or prepaid debit cards.³ If you still receive one, a post office is a valid place to cash it.

Cashing a Postal Money Order

Postal money orders are the most commonly cashed item at the counter. Because USPS both issues and guarantees them, any branch can pay one out, up to the $1,000 domestic maximum.²

Whether you actually walk out with the full amount in cash depends on what the branch has available. Cashing is subject to funds on hand, and clerks typically start the day with little cash, accumulating it as customers make purchases.² A larger branch or a later visit improves the odds for a $1,000 money order. There is no fee to cash one.

Bring the money order and valid ID. Do not sign the endorsement area on the back before you arrive. The endorsement must stay blank until you are at the counter, where you sign in the presence of a USPS employee. If you cannot write, you may sign with a mark as long as a non-USPS witness is present. USPS can refuse payment if your identity is not established to the clerk’s satisfaction.⁴

The clerk will inspect the money order’s security features under light, watch you sign the back, log the serial number, and pay out the face value.

Check a Money Order Before You Accept It

If someone paid you with a postal money order, verify it before you take it to the post office. USPS will refuse to pay on a counterfeit, and fake money orders are a staple of online payment scams. Two valid designs are currently in circulation.

Legacy Green Design

In use since 2009, this design is green and purple with a U.S. Mail eagle logo in the center. Held up to a light, a Benjamin Franklin watermark repeats from top to bottom on the left side. To its right, a vertical security thread with the letters “USPS” weaves in and out of the paper.⁵

Red and Blue Design

Released in July 2025, the newer design uses red and blue ink with subtle images of an eagle head and American flag. Two watermarks appear only under light: a Pony Express rider on the left and the words “United States Postal Service” in a rectangular box on the right. A security thread just right of the Pony Express watermark shows “USPS” alternating right-side up and upside down. There is also a QR code that links to a USPS page where you can check the money order’s status.⁶

On either design, watermarks that are clearly visible without a light source are a warning sign that the document may be counterfeit.⁵ Look also for erasures, discoloration, or altered amounts. A common fraud pattern: a buyer sends a money order for more than the agreed price and asks you to refund the difference. When the money order turns out to be fake, you lose both the item and the cash you sent back.⁷

Large Transactions Trigger Reporting

USPS is classified as a money services business under the Bank Secrecy Act. Cash more than $10,000 in money orders in a single day and USPS is required to complete a Funds Transaction Report on PS Form 8105-A.⁸ The clerk will collect your name, address, date of birth, Social Security number, and photo ID details. USPS may also file a Suspicious Transaction Report for a transaction that raises concerns, regardless of amount.

Being reported is not itself an accusation. Breaking a transaction into smaller pieces to stay under $10,000, though, is a federal offense known as structuring.

If the Post Office Can’t Cash Your Check

For a personal check, a paycheck from a private employer, or a cashier’s check, the post office is not an option. The bank named on the check will often cash it for the payee even without an account there, sometimes for a small fee. Many large retailers cash payroll and government checks. Check-cashing stores will take almost any valid check but tend to charge several percent of the face value. Opening a basic checking account, including an online one, removes those fees for most check types.
