Which extra service provides tracking for packages?

The extra service that provides tracking for packages is USPS Tracking. This service allows both senders and recipients to monitor the progress of their packages throughout the shipping process. USPS Tracking is integrated with most domestic shipping options, enabling customers to get real-time updates on the location and status of their packages. This transparency is essential for effective shipping, as it helps ensure peace of mind and allows recipients to plan for delivery.

While Registered Mail, Signature Confirmation, and Collect on Delivery are useful services, they do not inherently provide the same level of tracking as USPS Tracking. Registered Mail does offer enhanced security and tracking, but its primary purpose is to safeguard valuable items during transportation rather than providing continuous tracking updates. Signature Confirmation ensures that a package is delivered only to the recipient or their authorized agent, requiring a signature upon delivery, but does not provide real-time tracking updates in the same way. Collect on Delivery is a service where payment is collected upon delivery, which may include tracking, but again, it is not the primary feature. Thus, the most direct and widely used service for tracking packages is indeed USPS Tracking.
