If Express Mail has a signature waiver, what can the carrier do?

When Express Mail has a signature waiver, it allows the carrier to deliver the package without obtaining a signature from the recipient. This waiver simplifies the delivery process by enabling the carrier to leave the package in a more convenient location for the recipient, such as their mailbox.

Choosing to put the package in the mailbox is aligned with the intention of the signature waiver, which is designed for instances where the recipient may not be available to sign for the package. As a result, this method ensures the package is successfully delivered without the need for a direct handoff, adhering to the customer’s request for a signature waiver.

The other options are not applicable for packages with a signature waiver. Leaving the package at the post office would require a signature and can lead to delays in delivery, while returning it to the sender means the package isn't delivered at all. Simply delivering without scanning goes against postal regulations, as proper tracking is still required even if a signature isn't collected.
