USPS Tracking consists of 2 options: Electronic Service and Retail Service. With both options, mailers receive information about the delivery status of Priority Mail® service or Package Services, including the date, time, and ZIP Code™ of delivery. Other information available through Delivery Confirmation includes attempted deliveries, forwarding, and returns. All of this information is accessible through the Internet or via electronic file transfer.

Other special services such as insured mail, Registered Mail™, collect on delivery (COD), and special handling can also be combined with USPS Tracking. Return receipt service or restricted delivery may be used only if purchased in connection with insurance (more than $200), COD, or registry service. Fees for all special services are in addition to required postage.

The Electronic Service option allows your company to develop its own mailing profiles and analysis reports based on the information in the file we provide you. This option also allows customers to print their own labels or use preprinted labels.

If you choose to take advantage of the Electronic Service option, you must complete a testing and certification process.


Certification will test your barcoded labels and electronic file to ensure they meet our specifications, and will test the transmission of the electronic file to USPS®. The specifications for the labels and electronic file may be found in Publication 199, Intelligent Mail Package Barcode (IMpb) Implementation Guide for Confirmation Services and Electronic Verification System (eVS) Mailers; and USPS2000508: Barcode, Package, Intelligent Mail® Specifications.
