This Symbology is also known as Australian 4-state postal barcode, Australia Post Customer Barcode

This Symbology is used by Australia Post for Postal code and automatic mail sorting. Australia Post has chosen the 4-State Barcode, a derivation that is already used successfully by other postal administrations. It comprises four types of bars (the four states), each of which has a distinct name, value and barcode symbol.

4-State Barcode Bars

Sample of an Australia Post 4-State Barcode

This Symbology comes in several versions:

Notes

• The first number indicates the total number of bars in the barcode.
• FCC stands for "Format Control Code".
• DPID stands for "Delivery Point Identifier" (also named as "Sorting Code") which identifies destination of a piece of mail = 16 bars = 8 digits (using the N table).
• CustInfo stands for "Customer Info". Free-format customer-specific data area, may contain any information not interpreted by Australia Post = 16 or 31 bars. If it is numeric only, it can be encoded using the N table, thus accommodating 8 or 15 digits. Otherwise the C table has to be used, thus accommodating 5 or 10 chars. However, BarcodeItem implementation is based on C encoding table only.

The value to encode has the following structure:

• 2 digits for Format Control Code (FCC) which only valid values are: 11, 87, 45, 92, 59, 62, or 44 (See table above for more information about each FCC)
• 8 digits for Sorting Code or Delivery Point Identifier (DPID)
• Alpha numeric characters (free format) for Customer Information Field (only available for FCC equals to 59, 62, or 44)
  • For FCC equals to 59, this field is limited to 5 characters
  • For FCC equals to 62 or 44, this field is limited to 10 characters
• Reed Solomon Error Correction

BarcodeItem implements C Encoding Table which allows you to encode Customer Information consisting of:

• Uppercase characters, from A to Z
• Lower case characters, from a to z
• Space and # characters
• Digits 0 to 9

In order to get an Australia Post 4-State barcode image, please follow these steps:

• Set the Symbology property to AustraliaPost
• Setting up dimensions and quiet zones:
  • Set the Postal4StateTrackerBarWidth property to a value ranging from 0.016 to 0.024 (Values are expressed in Inches)
  • Set the Postal4StateTrackerBarHeight property to a value ranging from 0.039 to 0.063 (Values are expressed in Inches)
  • Set the Postal4StateBarsSpacing property to a value ranging from 0.016 to 0.028 (Values are expressed in Inches)
  • Set the QuietZone property to 0.24, 0.08, 0.24, 0.08 - Left, Top, Right, Bottom (Value is expressed in Inches)
• Setting up the value to encode:
  • Set the Code property to a value with the following structure:
    • 2 digits for Format Control Code (FCC) which only valid values are 11, 87, 45, 92, 59, 62, or 44
    • 8 digits for Sorting Code or Delivery Point Identifier (DPID)
    • (Optional) Alpha numeric characters (free format) for Customer Information Field (only available for FCC equals to 59, 62, or 44)
      • For FCC equals to 59, this field is limited to 5 characters
      • For FCC equals to 62 or 44, this field is limited to 10 characters
  • Examples of values that can be set to the Code property based on the stated in the previous point:
    • 1139987520
    • 1167671415
    • 5932211324A124B
    • 5977665544C A P
    • 5956439111ABA 9
    • 6282224535555439
    • 6279438541AaaB 155
    • 6243289421CAM Num 20
  • Reed Solomon Error Correction is automatically calculated and appended by BarcodeItem.
    • Tip: You can rid of the Reed Solomon values from the Human Readable text by setting up to False the DisplayChecksum property.
• Set the CodeAlignment property to AboveLeft
• Set the Text property to an Empty string

Code property = 1139987520 will produce the following barcode image:

Code property = 5956439111ABA 9 will produce the following barcode image:

Code property = 6243289421CAM Num 20 will produce the following barcode image:
