Postnet barcode. This symbology usually gets printed by U.S. Post Office on envelopes. Postnet symbology allows only numeric values to be encoded. The bar code itself can encode either a standard 5-digit Zip Code, a Zip+4 code, or a full 11-point delivery point code.

Important: you can also use BarCode Windows Forms or Web ImageControl instead. To use the Windows Formscontrol in Visual Studio please open Toolbox and open "Bytescout Software" tab and drag-n-drop "BarCode" control into your WinForms or ASP.NET application (in design mode)

Visual Basic:

Imports Bytescout.BarCode

Module Module1

Sub Main()

' Create new barcode

Dim barcode As New Barcode()

' Set symbology

barcode.Symbology = SymbologyType.Postnet

' Set value

barcode.Value = "12345123412"

' Save barcode to image

barcode.SaveImage("result.png")

' Show image in default image viewer

Process.Start("result.png")

End Sub

End Module
