What is Delivery Confirmation?
Delivery Confirmation is an extra service. This service provides the customer with the date and time the package was delivered via use of a tracking number. For some mail services it has a fee associated with its use. It is free for Priority Mail. Delivery Confirmation can be used with First Class, Priority Mail, Media Mail, Standard Post and Parcel Select services only. pbSmartPostage™ requires customers to use an electronic confirmation service for shipping labels on packages.
