Which type of service includes delivery confirmation?

Delivery confirmation is a service feature that allows senders to track their mail and receive notification when the item has been delivered. Both Priority Mail and First-Class Mail from the United States Postal Service offer this benefit.

Priority Mail provides a quicker delivery service, typically within 1-3 business days, and includes various tracking options that include delivery confirmation. This service is particularly valuable for time-sensitive documents and packages.

First-Class Mail also offers delivery confirmation for letters, large envelopes (flats), and packages. This is beneficial for personal and business correspondence, as it assures senders that their item reached its destination.

Standard Mail, on the other hand, does not include delivery confirmation as it is primarily used for bulk mail and advertising purposes, which typically do not require tracking or confirmation of delivery.

Thus, the correct answer encompasses both Priority Mail and First-Class Mail, which both provide delivery confirmation services, making the combined option the accurate choice.
