What does the USPS require for items weighing over 13 ounces when shipped?

For items weighing over 13 ounces, the USPS requires a tracking number to ensure that the package can be monitored throughout its journey. Tracking plays a crucial role in enhancing the security and reliability of mail delivery, as it allows both the sender and receiver to follow the package's status. This requirement is part of USPS's commitment to providing safe and efficient delivery services while also enabling customers to confirm the successful arrival of their items.

While declaration forms, insurance policies, and signature confirmations are important in various contexts of mailing, they are not universally mandated for all items over 13 ounces. The focus of this requirement is primarily on tracking, reflecting the USPS's focus on accountability and transparency in mail handling processes.
