Cash on delivery, often shortened to COD, is a shipping arrangement where the buyer pays for the goods at the moment the package arrives rather than at the time of ordering. The delivery driver collects payment at the door and won’t hand over the package until the money is in hand, and the carrier then forwards those funds back to the seller. It exists mainly for buyers who don’t want to pay online in advance or don’t have a bank account to pay with; roughly 4.2% of U.S. households remain unbanked.1Federal Deposit Insurance Corporation. 2023 FDIC National Survey of Unbanked and Underbanked Households
How the Transaction Actually Moves
The whole idea is a simultaneous swap: product for payment, face to face at the doorstep. When a seller ships a package COD through USPS, they pay the regular postage plus a separate COD service fee upfront and attach Form 3816 to the package. That form tells the delivery carrier exactly how much to collect and where to send the money.2United States Postal Service. PS Form 3816
When the package reaches your address, the driver won’t release it until the full amount is paid. The instructions on the form are blunt: “DO NOT deliver this article until payment is collected.”2United States Postal Service. PS Form 3816
Once the carrier has the payment, how the seller gets paid depends on how you paid the driver. Pay by check, and USPS forwards your check directly to the seller. Pay in cash, and USPS deducts a money order fee from the amount collected and mails the seller a postal money order instead.3United States Postal Service. Domestic Mail Manual S921 – Collect on Delivery (COD) Mail That money order fee comes out of the buyer’s pocket, so the amount collected at the door on cash payments is slightly higher than the item price alone.
Which Carriers Offer COD, and How Much They Collect
Not every carrier handles COD the same way. The limits and costs matter, especially if you’re shipping something expensive.
USPS caps COD collections at $1,000 per package and accepts payment from recipients by cash, personal check, or pin-based debit card. The debit option only exists when the seller participates in USPS electronic funds transfer.4United States Postal Service. Notice 1232United States Postal Service. PS Form 3816 That $1,000 ceiling makes USPS COD workable for smaller items but rules it out for higher-value shipments.
UPS charges a $22.50 COD surcharge per package as of its 2026 rate schedule.5UPS.

Can You Open the Package Before Paying?
No, and this is the part that catches most buyers off guard. Under the Uniform Commercial Code, which governs commercial sales, a buyer “is not entitled to inspect the goods before payment of the price when the contract provides for delivery ‘C.O.D.'”7Legal Information Institute. UCC 2-513 – Buyers Right to Inspection of Goods USPS reinforces this in its driver instructions: “DO NOT allow the recipient to examine the contents before payment.”2United States Postal Service. PS Form 3816
What this means in practice: you can confirm a package arrived, but you’re paying blind on what’s inside. If the item turns out to be damaged or wrong, your remedy is a return or dispute with the seller after the fact, not refusing payment at the door based on what you see. COD gives you assurance that something shows up. It doesn’t guarantee what shows up is exactly what you ordered.
What Happens If You’re Not Home or Refuse to Pay
If you’re not there when the driver arrives, or you decide you don’t want the package, delivery fails. The item goes back to the seller as a “Return to Origin” shipment, and the seller absorbs the return postage on top of the original shipping cost and COD service fee. From the buyer’s side, missing the driver usually means arranging a redelivery attempt or picking the package up.
A few other practical points on payment. Drivers don’t make change, so you need the exact amount ready. If you’re paying by check through USPS, the check has to be made payable to the seller, not the postal service.
Card on Delivery and Other Modern Variations
The “cash” in cash on delivery is increasingly a misnomer. Many carriers and logistics companies now offer “Card on Delivery” or “Electronic COD,” where the driver carries a mobile card reader and takes debit or credit payments at the door. The mechanics stay the same, but you don’t need a stack of bills waiting. For sellers, electronic collection also speeds up remittance because funds move digitally rather than cycling through postal money orders.
Beyond COD itself, online payment platforms with buyer protection have absorbed much of the trust concern that once drove people to COD. PayPal and major credit card networks offer refund guarantees when a product doesn’t arrive or doesn’t match its description, and escrow services hold funds until the buyer confirms receipt on high-value purchases. COD hasn’t disappeared, but it’s now one option among several for buyers who don’t want to pay a stranger upfront.
