What is USPS Delivery Confirmation?

Created:   |   Updated:

Also known as “USPS tracking”, delivery confirmation helps you track and confirm your packages by letting you know the date and time your shipment has been delivered or that a delivery attempt was made.  

Delivery confirmation, is good for many situations, such as when you are shipping high value goods, when you want to know when your packages are delivered, or when you want your customers to know when they should expect their shipments.

Delivery confirmation or USPS Tracking is required when insuring a package, either through USPS or Shipsurance.

NOTE: delivery confirmation/USPS Tracking is not the same as insurance.

Tracking is also helpful when reporting a lost shipment. If a First-Class Mail or Priority Mail shipment has not arrived within five (5) Postal business days from its date of mailing, you can report the loss via phone or web:

  • Call 1-800-ASK-USPS (1-800-275-8777) where a customer service representative will document your mail loss complaint.
  • Visit the Postal Inspection Service Web site and complete a mail loss report.
NOTE: delayed Priority Mail Express shipments should be reported as soon as the service commitment has been missed. Learn more.

Access tracking information online or by phone:

    Hello Miriam, and thank you for posting to our support center.

    Unfortunately, because ShippingEasy does not actually handle or delivery packages, we would recommend you contact USPS directly via phone at 1 (800) 275-8777. They should be able to provide further assistance with obtaining delivery confirmation for any packages you shipped with them.

    Thank you.
