The default is the waiver
For ordinary parcels USPS already delivers without collecting a name. Searching for how to waive it is usually a sign that somebody expected a signature they never bought.
Signature mechanics
Waiving the signature, and the claim it can cost you
Most searches for this land on a misunderstanding: on Priority Mail and Ground Advantage there is nothing to waive, because no signature is taken unless you pay for one. The waiver is real on Priority Mail Express, and USPS rules state that when signature service is not requested or a waiver of signature is requested, additional coverage is not available.

Nothing to waive, something to buy
On ordinary parcels the default is already a release. The decision is whether to spend a few dollars reversing it.
A 16 lb box, and what a signature would add
The anchor is a 16 x 14 x 10 in box at 16 lb, quoted 2026-07-28 from Newark, NJ 07102 to Atlanta, GA 30303. USPS Ground Advantage came back at $22.62, the whole checkout amount. No signature is collected on that label as it stands, and reversing that costs $4.15 electronic.

| Service | Default handling | What a waiver changes |
|---|---|---|
| USPS Ground Advantage | Delivered without a signature | Nothing; there is no signature in the base product to remove |
| Priority Mail | Delivered without a signature | Nothing; Signature Confirmation is a separate purchase at $4.15 electronic |
| Priority Mail Express | Signature record included only when requested at purchase | Requesting a waiver, or simply not requesting signature service, removes the ability to buy additional coverage |
| Item covered above $500 | USPS supplies a signature as the delivery record | Not something a mailer waives at will; the coverage band drives it |
When signature required service is not requested or when waiver of signature is requested, additional insurance is not available.USPS Domestic Mail Manual 503, section 4.1.1, additional coverage for Priority Mail Express, pe.usps.com, fetched 2026-07-28
Read that clause carefully, because it links two things people treat as separate. On Express, the choice not to collect a signature closes the door on buying cover above the $100 the service already includes. You cannot have the convenience of a doorstep release and the higher ceiling at the same time.
What a waived signature costs at claim time
A delivery scan places a package at a ZIP code at a moment. That is what you are left holding when a buyer says nothing arrived, and it is thin. USPS asks lost-package claims on Priority Mail and Ground Advantage to wait 15 days from mailing and to be filed within 60, and damage claims within 60, and every one of those files goes better with a name attached to the handover.
Our own protection has the same appetite for evidence. Claims under SMKlog shipping protection need an invoice or other proof of value, the tracking record, customer correspondence and photographs where the item was damaged. A signature is not on the required list, but it is the fastest way to close down the argument that the package never got there.
The sensible rule
Leave the release in place on low-value orders, where a signature costs a meaningful share of the margin and a redelivery annoys the buyer. Buy the signature the moment an order is worth more than the cost of losing the dispute, which for most sellers sits somewhere between $75 and $150. Whichever way you go, decide it at the rate screen, because none of it can be added after the label prints.
Express trades cover for convenience
Skip signature service on Priority Mail Express and the additional coverage option goes with it. On a valuable Express shipment, that is the wrong economy.
Tell the buyer either way
A signature requirement the recipient does not expect turns into a missed attempt and a trip to the Post Office. One line in the dispatch email prevents most of that.
Signature waiver questions
How do I waive the signature on a USPS package?
On Ground Advantage and Priority Mail there is nothing to waive, because no signature is collected unless Signature Confirmation is added. The waiver exists on Priority Mail Express, where the signature record is included only if requested at purchase.
What does waiving the signature cost me?
On Priority Mail Express it costs the ability to buy cover above the included $100. DMM 503 states that when signature service is not requested, or a waiver of signature is requested, additional coverage is not available.
Does a missing signature hurt a claim?
It weakens it. Without one the record is a scan showing a time and a ZIP-level location, which is much harder to use against a buyer who says the package never arrived.
How much does adding a signature cost?
Signature Confirmation is $4.15 electronic or $5.15 retail per USPS Notice 123, effective 2026-07-12. On our anchor box, a 16 x 14 x 10 in carton at 16 lb quoted at $22.62 on 2026-07-28, that is under a fifth of the postage.
