If Priority Mail is applied with additional services, what changes?

When Priority Mail is applied with additional services, it often requires signature confirmation, which is a service that adds an extra layer of security and accountability to the delivery process. Signature confirmation ensures that the package is only released to the person who is authorized to receive it, providing proof of delivery. This is particularly important for valuable or sensitive items where verification of receipt is essential.

The other options do not accurately represent the changes that occur with additional services. For example, while additional services may enhance the delivery experience, they do not automatically make the mail faster; Priority Mail already has its own delivery standards. Additionally, using additional services does not convert a Priority Mail package into an Express Mail package, which is a different service altogether with distinct pricing and delivery commitments. Lastly, Priority Mail can be sent internationally; it’s the specific additional services that may have restrictions, but the base product itself does not limit international sending. Therefore, the requirement for signature confirmation stands out as the key change when additional services are added to Priority Mail.
