The Intelligent Mail Package Barcode ( IMPB ) is used on mail in the United States. Barcodes of this symbology are used only for packages, as opposed to Intelligent Mail barcodes, which are used for postcards, letters, and flats. This barcode can encode package tracking information required to sort and deliver packages more efficiently with the piece-level tracking capability.

Add the Bar Code to a Report

Drag the XRBarCode item from the DX.25.2: Report Controls tab and drop it onto the report.
Set the XRBarCode control’s Symbology property to IntelligentMailPackage (an object of the IntelligentMailPackageGenerator) type).
Specify common barcode properties and properties specific to Intelligent Mail Package.

Specific Properties

Use the barcode’s FNC1Substitute property to get or set the symbol (or set of symbols) in the barcode’s text that will be replaced with the FNC1 functional character when the barcode’s bars are drawn.

Runtime Example

The following code creates the Intelligent Mail Package barcode and specifies its properties.
