USPS Adult Signature Confirmation | Overview

When the shipment reaches its destination, Adult Signature Confirmation requires the signature of an individual at the residence who is at least 21 years of age, who provides proof of age with a government-issued photo identification that lists the date of birth and/or age of the signer prior to delivery. The USPS maintains a record of delivery (including the recipient’s signature) for two years.

Adult Signature Confirmation allows merchants who have been authorized to ship alcohol and tobacco to ensure they uphold their end of what’s required by law. Namely that only individuals of-age receive the age-restricted merchandise.
