History of CODE 39

• Origins and Development

  The CODE 39 barcode was developed in 1974 by Dr. David Allais and Ray Stevens of Intermec. Its design aimed to provide a straightforward and reliable method of encoding data that could be easily read by barcode scanners.

• Evolution Over Time

  Since its inception, CODE 39 has undergone various modifications to enhance its readability and efficiency. Today, it remains one of the most widely used barcode symbologies.

Structure of CODE 39

• Character Set

  CODE 39 can encode 43 characters, including uppercase letters (A-Z), numbers (0-9), and special characters like space, $, %, +, -, ., and /.

• Start and Stop Characters

  Each CODE 39 barcode begins and ends with a special asterisk (*) character, serving as the start and stop symbol.

• Check Digit

  While the standard CODE 39 does not include a check digit, an optional modulo 43 check digit can be added to enhance data integrity.

How CODE 39 Works

• Encoding Process

  Each character in CODE 39 is represented by a combination of nine elements (five bars and four spaces), with three out of nine being wider than the others, hence the name "3 of 9."

• Decoding Process

  Barcode scanners read the widths of the bars and spaces, translating them into corresponding characters using the CODE 39 encoding table.

Applications of CODE 39

• Inventory Management

  CODE 39 is widely used in inventory systems for tracking products, managing stock levels, and streamlining the order fulfillment process.

Advantages of CODE 39

• Simplicity

  CODE 39's straightforward encoding and decoding process makes it easy to implement and use.

• Versatility

  The ability to encode both letters and numbers allows for diverse applications across different industries.

• No Special Fonts Required

  CODE 39 can be printed using standard fonts, eliminating the need for specialized printing equipment.

Limitations of CODE 39

• Size Constraints

  Due to its low density, CODE 39 barcodes can become quite large, making them unsuitable for small items.

• Limited Character Set

  The absence of lowercase letters and other symbols restricts the amount of data that can be encoded.
