Tracked Flats

Misuse of the Intelligent Mail® Package Barcode (IMpb®)

Employees are reminded that a First-Class Mail® flat-size piece is not eligible for IMpb tracking.

Customers who request to receive IMpb tracking capability on a First-Class Mail flat-size piece must purchase Certified Mail® as an add-on Special Service. A customer mailing a First-Class Mail flat-size piece cannot request to pay First-Class Mail parcel prices just to receive IMpb tracking.

As an alternative, a customer may prepare the mailpiece as a First-Class Mail parcel (see DMM® section 101.6.4, First-Class Mail Parcels) or select another qualifying service such as Priority Mail®, which provides IMpb tracking.
