Postal Service Practice Exam 2026 – Comprehensive Study Resource

“Additional Service” refers to a variety of services provided by the postal service that go beyond the standard basic mail delivery. This includes options such as insurance, which protects against loss or damage of valuable items during transit, and delivery confirmation, which provides proof that a package has been delivered to the recipient. These services are designed to enhance the mailing experience by offering customers extra features that cater to their specific needs, such as tracking their packages or securing valuable contents.

In contrast, the other options focus on limited or unrelated definitions of services. For instance, express delivery options alone do not cover the full spectrum of additional services. Basic delivery services are simply part of what the postal service provides and do not include the additional features that customers can opt for. Services related to postal employee management are unrelated to customer-facing offerings and, therefore, do not fit into the category of additional services available for mail processing or delivery.
