Identcode Barcode Introduction
Identcode is also known as German Postal 2 of 5 Identcode, Deutsche Post AG Identcode, Deutsche Frachtpost Identcode, Identcode, Code Identcode, Deutsche Post AG (DHL).
Identcode barcode Symbology is used by German Post (Deutsche Post AG) (Deutsche Frachtpost).
The Identcode contains a tracking number providing an identification of the customer (sender) and the mail piece.
The value to encode length is fixed to 11 digits plus 1 digit checksum which is automatically calculated by Java Barcode. The value to encode must have the following structure:
  • 2 digits for ID of primary distribution center
  • 3 digits for Customer ID
  • 6 digits for Mailing number
  • 1 digit is the checksum digit

Sample of a Deutsche Post Identcode Barcode
Identcode Encoding Data Scope
Identcode Barcode for Java supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How to Generate Identcode Barcode in Java Class?
The following Java code illustrates how to create a Identcode barcode, and output to various formats.
1     Linear linear = new Linear(); 
2 linear.setType(Linear.IDENTCODE);
3 linear.setData("12345678901");
4 linear.renderBarcode("c:/barcode.gif");

5 BufferedImage bufferedImage = linear.renderBarcode();

6 byte[] barcodeBytes = linear.renderBarcodeToBytes();

7 Graphics2D g = ...
8 Rectangle2D rectangle = ...
9 linear.renderBarcode(g, rectangle);

10 OutputStream outputStream = ...
11 linear.renderBarcode(outputStream);
  • Create a Linear barcode object (line 1)
  • Set Linear object barcode type to Identcode (line 2)
  • Set Identcode barcode data to encode (line 3)
  • Encode generated Identcode barcode into gif image file (line 4)
  • Generate Identcode and output to BufferedImage object (line 5)
  • Generate Identcode in bitmap and output to byte[] (line 6)
  • Generate Identcode and draw to defined area (Rectangle2D) on Graphics2D (line 7-9)
  • Generate Identcode and output to OutputStream (line 10-11)
How to Generate Identcode Barcode Image in Java Web Applications?
There are two methods to create Identcode barcode images in your Java web applications.
  1. The simplest way is to stream barcode image using our buildin barcode servlet application.
    • Download the Barcode for Java Trial Package, and unzip it.
    • Under java_barcode_trial package, copy barcode folder to your java servlet container like tomcat.
    • Restart tomcat. Now you have installed successfully
    • To test your installation, open your web browser and navigate to:
      http://YourDomain:Port/barcode/linear?Data=12345678901&Type=IDENTCODE.
    • To create barcode image in your JSP or html page, you need pass the url to IMG tag src value. For example,
      <img src="http://YourDomain:Port/barcode/linear?Data=12345678901&Type=IDENTCODE" />
      Using this method, it will not generate any barcode images in your server side.
  2. The second method is to generate barcode images in your server side.
    • Create a barcode image in server side, like
      Linear linear = new Linear();
      linear.setData("12345678901");
      linear.setType(Linear.IDENTCODE);
      linear.renderBarcode("C:/Tools/Tomcat 5.5/webapps/YourWebApp/barcode-images/barcode.gif");
    • In your JSP or HTML page, you need use IMG tag to display generated image, like
      <img src="http://YourDomain:Port/YourWebApp/barcode-images/barcode.gif" />

Identcode Barcode Property Settings
  1. Set the type property to Linear.IDENTCODE
    Servlet URL Parameter: "Type". Value: 20. Sample: &Type=20.
  2. Set the data property with the value to encode. Type is String.
    Servlet URL Parameter: Data.
    • Valid Data Scope:
      • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    • Valid Data Format:The valid data length should be 11 digits. And extra last digit is the checksum digit, do not include it in the data property.
    • Sample: "12345678901".
  3. addCheckSum property is not applied here. Barcode Library will always add a check character in the last digit.
  4. Barcode image size settings.
    • Set property uom (Unit of Measure) for properties X, Y, leftMargin, rightMargin, topMargin and bottomMargin.
      Default is Linear.UOM_PIXEL (0). Valid values are Linear.UOM_PIXEL (0), Linear.UOM_CM (1), Linear.UOM_Inch (2).
      Servlet URL Parameter: "UOM". Value: 0 (pixel), 1 (cm), 2 (inch). Sample: &UOM=0.
    • Set the X (for barcode module width) and Y (for barcode module height) properties.
      Both types are float. Default X is 3. Y is 75.
      Servlet URL Parameter: "X", "Y". Sample: &X=3&Y=75.
    • Set the leftMargin, rightMargin, topMargin and bottomMargin properties, and types are all float.
      Default values are 0 for all 4 margin settings.
      Servlet URL Parameter: "LeftMargin", "RightMargin", "TopMargin", "BottomMargin". Sample: &LeftMargin=0.
    • Set the resolution property (Value is expressed in DPI - Dots per inch).
      Default is 72 dpi.
      Servlet URL Parameter: "Resolution". Sample: &Resolution=72.
  5. Setting up text style in barcode image.
    • Set the showText properties. If this value is true, barcode data will be displayed with the barcode.
      Default is true.
      Servlet URL Parameter: "ShowText". Value: "t" (true), "f" (false). Sample: &ShowText=t.
    • Set the textFont property. The font used to display text in barcode image.
      Default is new Font("Arial", Font.PLAIN, 11).
      Servlet URL Parameter: "TextFont". Value format: [font name]|[font style]|[font size]. Sample Values: &TextFont=Arial|Bold|12
  6. With rotate property, you can display barcode horizontally or vertically.
    Default value is 0.
    Servlet URL Parameter: "Rotate". Sample: &Rotate=0.
    Value can be:
    • 0 (Linear.ANGLE_0),
    • 1 (Linear.ANGLE_90),
    • 2 (Linear.ANGLE_180),
    • 3 (Linear.ANGLE_270).
