Which USPS service is automatically included for PME, PM, and FCM Package Service?

The correct answer is tracking. For packages sent via PME (Priority Mail Express), PM (Priority Mail), and FCM (First-Class Mail) Package Service through the United States Postal Service, tracking is automatically included as part of the service. This feature allows senders and recipients to monitor the progress of their packages throughout the shipping process, providing transparency and increased security for both parties. Tracking adds an essential layer of convenience, enabling customers to see when their packages are expected to arrive and if there are any delays.

The other options, while they may be associated with various USPS services, are not included by default for all the package services listed. For example, insurance typically requires an additional fee and is not standard for every package service. Similarly, delivery confirmation is a separate service that may need to be purchased for certain types of mail, and registered mail is a more secure and specialized service that is not automatically included with standard package services. Hence, tracking stands out as a fundamental feature provided with the specified services.
