How much does USPS Signature Confirmation cost?
$5.15 when bought at a retail counter and $4.15 in its electronic form, per USPS Notice 123 on pe.usps.com, effective 2026-07-12 and checked 2026-07-27. The fee is added on top of whatever the postage costs.
What is the difference between Signature Confirmation and Adult Signature?
Signature Confirmation records that a person accepted the package. Adult Signature Required, at $9.70 in the same fee chart, obligates the carrier to collect that signature from an adult, and the Restricted Delivery version at $10.00 narrows it to a named recipient. They solve different problems: proof versus control.
Is a signature worth it for marketplace sales?
For expensive items, usually. A signed delivery record is the strongest evidence a seller can hold in an item-not-received dispute, and platforms tend to weigh it heavily. For a twenty-dollar sale, spending $4.15 to collect that evidence rarely makes sense; for a four-hundred-dollar one it's cheap.
Can I add a signature requirement in SMKlog checkout?
Signature options appear during checkout whenever the carrier you picked supports them on your route. Quote the package first; the add-ons that apply show up before payment.
