USPS 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. It is also known as “USPS tracking”.
Delivery confirmation is good for many situations, such as when you are shipping high-value goods, want to know when your packages are delivered, or want your customers to know when they should expect their shipments.
Report A Lost Shipment
Delivery confirmation 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.
View real-time tracking status from your ShipStation account via the Shipments tab
Use the Track & Confirmtool on usps.com
Contact the USPS direct at 1-800-222-1811.
