This guide provides information about the United States Postal Service (USPS) Informed Visibility Mail Tracking & Reporting (IV-MTR) application, which allows mailers to track letter and flat containers, handling units (trays, tubs, and sacks), bundles, and pieces.
IV-MTR does not provide mail tracking data on packages, to include associated containers, handling units, and bundles. The intended audience for this guide is mailers. This guide describes the prerequisites for receiving mail tracking data through IV-MTR, the data provisioning options available, and how to use the application.
This guide also provides information about interpreting scan data.
