What do signature requirements aim to accomplish in package delivery?

Signature requirements in package delivery are designed to ensure that the recipient receives their package personally. This is crucial for several reasons, including the security of the package and the verification of the recipient's identity. When a signature is required, it confirms that the package has been delivered to the intended person, thereby reducing the risk of theft or delivery to the wrong individual. This measure helps in maintaining accountability and provides a safeguard for both the sender and the recipient.

While options like increasing mailing costs or making the delivery process quicker may impact logistics, they do not address the fundamental purpose of signature requirements. Additionally, allowing anyone to collect the package contradicts the intent of having a signature requirement, which is to ensure that only the designated recipient has access to the delivery.
