DMM Revision: Intelligent Mail Barcode Tracing Migrated to Informed Visibility

Effective March 5, 2018, the Postal Service™ will revise Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®), sections and 507.10, to replace Intelligent Mail® barcode (IMb) Tracing with Informed Visibility® (IV).

The Postal Service announced that the IMb Tracing system was retired on November 30, 2017. As a result, the Postal Service required all IMb Tracing customers to migrate to Informed Visibility in order to continue receiving data. The migration from IMb Tracing to IV supports the following two specific purposes:

n Provides a secure method of file transmission, and

n Eliminates the end of life issues users encountered with the IMb Tracing systems.

Although we will not publish these revisions in the DMM until March 5, 2018, the standards are effective immediately.
