POSTNET Barcodes

POSTNET is a bar code symbology used by the US Postal Service to encode ZIP codes on mail items.

Each digit is encoded using a combination of five half-height or full-height vertical bars. There is a full-height vertical bar to the left and right, and a check digit after the ZIP code (5 digits) or the ZIP+4 code (9 digits).

C# Sample Code

void DrawPostnet(string text, Graphics g, Rectangle rect)
{
  Barcode bc = new CommStudio.Barcodes.Barcode(BarcodeStyle.Postnet);
  bc.DisplayCaption = true;
  bc.Render(text, g, rect);   
}

VB.NET Sample Code

Sub DrawPostnet(text As String, g As Graphics, rect As Rectangle)
  Dim bc As New CommStudio.Barcodes.Barcode(BarcodeStyle.Postnet)
  bc.DisplayCaption = True
  bc.Render(text, g, rect)
End Sub
