Delivery Confirmation allows you to verify the date and time of delivery of your mail pieces or, if the delivery was unsuccessful, the date and time of the delivery attempt.
The service is currently available for First Class Mail packages, Priority Mail and Package Services parcels, which include Parcel Post, Library, Media Mail and Bound Printed Matter.
You may combine Delivery Confirmation with other services such as COD, insured mail, registered mail, parcel airlift (PAL) or special handling.
There is no charge for Delivery Confirmation when you ship by Priority Mail and provide an electronic file to the Postal Service.
