TYPE_CODE_11




Code 11 is a linear barcode symbology that is primarily used for labeling telecommunications equipment. It is known for its ability to encode numeric digits (0-9) and a dash ("-"), making it suitable for applications where only numeric data needs to be represented. Here's a detailed explanation of what Code 11 is and how to use it:

What is Code 11 Barcode?

Code 11, also known simply as Code 11, is a barcode symbology that was developed by Intermec in 1977. It is a discrete barcode, meaning it does not include any start or stop characters. Instead, it relies on the presence of two unique characters (denoted by asterisks) to indicate the beginning and end of the barcode. Code 11 is often used in telecommunications, such as labeling components like telecommunication cables and equipment.

Structure and Characteristics:

  • Character Set: Code 11 can encode numeric digits (0-9) and the dash character ("-"). This gives it a total of 11 possible characters (0-9, -).
  • Encoding: Each character in Code 11 is represented by a unique combination of bars and spaces. The asterisk (*) characters are used to mark the beginning and end of the barcode.
  • Check Digit: Code 11 includes a modulo-11 checksum digit to ensure data accuracy. This check digit helps detect errors during scanning.
  • Usage: Code 11 is suitable for applications where only numeric data and the dash character are needed, such as in the telecommunications industry for labeling equipment and components.

How to Use Code 11 Barcode:

To generate and use a Code 11 barcode effectively, follow these steps:

  1. Select a Barcode Generator: Use a barcode generation software, an online barcode generator, or a programming library that supports Code 11 symbology. Ensure that the generator includes options for encoding numeric digits and the dash ("-").

  2. Input Data: Enter the numeric data (0-9) and the dash ("-") that you want to encode into the Code 11 barcode. The data can represent serial numbers, part numbers, or other identifying information relevant to your application.

  3. Generate the Barcode: The generator will convert the input data into the Code 11 barcode format, automatically calculating and adding the necessary start and stop characters (asterisks) and the checksum digit.

  4. Print or Use Digitally: Once generated, print the Code 11 barcode on labels or packaging material. Ensure the barcode size is adequate for reliable scanning. Alternatively, use it digitally in applications where barcodes are scanned electronically.

Considerations:

  • Compatibility: Verify that your barcode scanner or reader supports Code 11 format to ensure accurate scanning.

  • Size and Quality: Code 11 barcodes should be printed clearly and at an appropriate size for reliable scanning by barcode scanners.

  • Application Requirements: Understand the specific requirements of your application to determine if Code 11 is suitable for your needs. Code 11 is particularly suited for labeling telecommunications equipment and other devices where numeric data is predominant.

In summary, Code 11 is a specialized barcode symbology designed for applications that require the encoding of numeric digits and the dash character. It provides a reliable method for labeling and tracking telecommunications equipment and components within the industry.
