What is typically not included in the service that USPS provides for Priority Mail?

Priority Mail offered by the United States Postal Service includes several beneficial features designed to enhance the shipping experience. Among these features are tracking, delivery confirmation, and insurance options for certain package values.

Signature confirmation, however, is not automatically included with Priority Mail service; it is an additional service that customers can request and pay for separately. This service requires the recipient's signature upon delivery, serving as proof that the item was received. While tracking and delivery confirmation are standard for multiple Priority Mail options, signature confirmation is an added layer of service, tailored for those who need it.

In this context, understanding that signature confirmation must be requested separately provides important clarity regarding the features included with the standard Priority Mail offerings.
