Signature Confirmation cost is $5.15 at a Post Office counter and $4.15 when bought electronically with a label, in the extra services sheet of Notice 123 read on November 13, 2026. It asks for a signature at delivery and adds it to the delivery record of the package. Adult Signature Required, for packages that must go to someone 21 or older who shows identification, costs $9.70; with Restricted Delivery to a named addressee, $10.00. The Domestic Mail Manual says the Postal Service keeps the record of an adult signature delivery, with the signature, for two years. The January 2027 filing raises the adult signature fees, which are competitive services, to $10.50 and $10.80; Signature Confirmation keeps its price. On a 2-pound Ground Advantage package to zone 5, a signature brings the counter total from $14.85 to $20.00.
Signature Confirmation cost and the other signature fees
| Service | Today | from Jan 17, 2027 |
|---|---|---|
| Signature Confirmation, at the counter | $5.15 | $5.15 |
| Signature Confirmation, electronic (online label) | $4.15 | $4.15 |
| Adult Signature Required (21 or older) | $9.70 | $10.50 |
| Adult Signature Restricted Delivery | $10.00 | $10.80 |
| Certified Mail (letters and flats) | $5.55 | $5.55 |
The fee is per piece and does not depend on weight or zone. It is added once to the postage and to any insurance fee. The electronic price applies when the signature is bought with a label online; at a counter the retail price applies. For a seller sending many packages with a signature, the gap between the two adds up, which is one more reason to buy labels online.

When a signature is worth paying for
Without a signature, a package can be left at the address. A signature makes the handover explicit: useful for expensive items, for buyers who might dispute receipt, and for anything that must not be left unattended. For age-restricted goods that the law allows to be mailed, Adult Signature is the tool. The signature does not insure the contents: for that, see the insurance page. For letters, the Certified Mail page is the right place.
