Selbstprüfende Codabar-Barcodes bestehen aus vier Strichen und drei Zwischenräumen. Die lineare Codabar-Symbologie besteht aus Ziffern (0-9), Start-/Stoppzeichen (a, b, c, d) und Sonderzeichen (. : / + - $). Codabar ist eine diskrete, selbstprüfende Barcode-Symbologie, die 16 verschiedene Zeichen und zusätzlich 4 Start-/Stoppzeichen codieren kann. Da der Codabar-Barcode selbstprüfend ist, definieren die meisten Standards die Prüfziffer nicht. Im Codabar-Barcode enthält jedes Zeichen 7 Elemente; 4 Striche und 3 Zwischenräume, die durch einen zusätzlichen schmalen Zwischenraum von ihren benachbarten Zeichen getrennt sind. Jeder kann einen Narrow-Wert von 0 oder einen Wide-Wert von 1 haben).
Codabar unterstützt bis zu sieben verschiedene Höhen, die in sieben verschiedenen Schriftarten mit unterschiedlichen Namen wie S1 oder S2 bereitgestellt werden, wobei jede von ihnen eine andere Höhe darstellt. Es ist sogar möglich, Codabar-Codes mit schreibmaschinenähnlichen Anschlagdruckern zu drucken, wodurch eine große Anzahl von Codes mit Zahlen erstellt werden kann, ohne dass ein System verwendet werden muss. Beispielsweise wird bei mechanischen Meilenzählern nach jedem gedruckten Code der Stempel des Druckers mechanisch auf die nächste Zahl gedreht.
Application Area
- Codabar is extensively used in medical and surgical equipment for simple encoding and decoding techniques.
- Used in the shipping industry to identify packages and shipments.
- It is also used in educational institutes and academic organizations.
- Codabar is applied to the tube for blood test specimens in order to confirm the individual ID.

Why use Codabar?
Codabar is widely supported, with most commercial barcode scanners like lasers and handhelds being capable of reading it. Codabar barcodes are simple to design and print. In many cases, a special font is all that is required, but no special software is required. Codabar is ideal for numeric data applications where its relatively low density is not an issue. It is used by FedEx on air bills, US libraries for item and location tracking, photo labs, United States blood banks, etc.
Advantages of Codabar
- Codabar is large and spaced, making it easy to scan and even easily print by the printer.
- It is scanning and self-checking, which eliminates errors when entering the code.
- Codabar font can be printed on a simple dot-matrix printer.
- It is an extremely versatile barcode standard that can be encoded and decoded by all types of printers, ranging from simpler to complex ones.
- With the simplest barcode standard, not much user training is required to understand the encoding and decoding techniques.
Limitations of Codabar
- Codabar can encode only numeric digits from 0-9 and a small set of characters.
- It has a very small fault tolerance for damage and destruction, and it is not easy to recover data even if a small portion of these barcodes is damaged.
- If a large amount of information has to be stored, like other linear barcode types, its length has to be increased.
- Disadvantages of Codabar are that it is quickly going out of style and being replaced by other, more efficient product identifiers.
How to Generate Codabar
We will discuss how to generate label using DRPU Barcode Software with Barcode Designing View module. You can also design barcode labels using Quick Barcode Mode of Software. Software provides 2D and linear barcode symbologies to design your labels that have a much higher capacity for data storage and can capture a barcode in any orientation, reducing scanning labor. Barcode maker tools are designed to create labels for tracking inventory levels, sales, orders, deliveries, and other warehouse or distribution centre needs.
