Whether you’re managing inventory or enhancing product traceability, this guide empowers you to make informed choices tailored to your specific needs.

Defining Code 93:

Code 93 was conceptualized by Intermec in 1982, and has since emerged as a sophisticated barcode symbology. Surpassing its predecessor, Code 39, in both data density and security, it is considered to be a superior option for labelling electronic components, retail inventory, and providing supplemental package delivery information.

It is tailored for alphanumeric data, and is capable of accommodating variable lengths, therefore embodying a versatile solution for encoding information. It is adept at encapsulating a lot of information within a short space. Additionally, A label generated in Code 93 proves approximately 25% shorter than its Code 39 counterpart.

It is a fortified and more secure version of Code 39, capable of reading both letters and numbers. This barcode is famously embraced even in the military and the automotive sectors. 

Additionally, it comprises characters that are nine modules wide, with a consistent pattern of three spaces and three bars. It stands as a testament to efficiency, security, and compact design in the realm of barcode symbology.

Code 128 Vs Code 93:

Code 128 excels in logistics, storing diverse data with high density. Code 93, a secure alternative, is compact and versatile, ideal for retail, manufacturing, and logistics applications. Let’s look at the difference between the two in detail:

1. Purpose and Application:

2. Character Set:

3. Data Density:

4. Industry Focus:

5. Special Considerations:

In essence, while both Code 128 and Code 93 barcodes share versatility, their specific strengths cater to distinct industry requirements, with Code 128 excelling in logistics data density and Code 93 providing a compact and secure alternative across multiple sectors.

Choosing the Right Kind of Barcode:

Choosing the right barcode involves considering the type of information you need to encode, known as the barcode character set. Understand your data requirements, then match them with a symbology, the barcode’s language. 

Ensure compatibility with your software, barcode scanner, and printer. Code 39 and Code 128 are often suitable for diverse applications, especially when space is available. Test symbologies to visualize how they represent your data effectively.

Applications of Code 93:

It excels in identification, labelling, and supplementary delivery information. Let’s look at these in detail together: 


In the logistics and transportation industries, Code 93 finds prominence as a reliable solution for identifying packages. Its compact size and high data density make it ideal for encoding crucial information on shipped or packaged containers, streamlining ordering and distribution processes.


Code 93’s versatility extends to retail, where it is employed for labelling electronic components and managing inventory. The symbology’s ability to handle diverse characters and provide additional security within the code makes it a preferred choice in retail environments.

Supplementary Delivery Information:

An interesting application of Code 93 lies in its usage by Canada Post for encoding supplementary delivery information. The symbology’s unique attributes make it well-suited for enhancing the efficiency of postal services by providing additional data on packages.

Advantages of Code 93:

Among many advantages of this code, its higher data density, compact size, and enhanced security features are extraordinary. We’ve explained these topics in detail below:

Higher Data Density:

One of the standout features of Code 93 is its ability to store more information in a smaller space. Compared to Code 39, a label produced in Code 93 is approximately 25% shorter. This higher data density proves crucial in applications where space is limited, such as on electronic components or small product labels.

Compact Size for Efficiency:

The compact size of Code 93 contributes to its efficiency, making it a practical choice for various industries. The symbology’s size advantage is particularly significant in scenarios where labels need to be placed on smaller items or in environments where space constraints are a concern.

Enhanced Security Features:

Code 93’s incorporation of two check characters in each symbol enhances the security of encoded data. This feature ensures the accuracy and reliability of the information, making Code 93 a preferred choice in applications where data integrity is critical, such as in package delivery systems.

Future Trends and Innovations:

In an era of evolution, Code 93 is bound to evolve too and be at par with emerging technologies. Learn more about them below:

Continuous Evolution:

As technology evolves, so does the landscape of barcode symbologies. Keeping an eye on emerging trends and innovations in the field can provide insights into potential advancements or new symbologies that may further enhance efficiency and security.

Integration with Emerging Technologies:

With the rise of technologies like the Internet of Things (IoT) and blockchain, the role of barcodes in data management is likely to evolve. Exploring potential integrations with these technologies can offer new opportunities for efficiency and transparency.

FAQ: Code 93 – Everything You Need to Know:

Will a very small barcode be declined?

Extremely small barcodes may pose readability challenges for scanners. It’s crucial to balance size with scanner compatibility to prevent potential declines.

How much data does the barcode contain?

The amount of data a barcode can hold varies. 1D barcodes like Code 128 store more linear data, while 2D barcodes, like QR codes, store extensive information.

What is the best barcode to use?

The ideal barcode depends on your specific needs. Code 128 and QR codes are versatile, but consider factors like data complexity, space, and industry requirements.

What is a 2D barcode?

A 2D barcode, such as a QR code or Data Matrix, encodes data in two dimensions, horizontally and vertically. They can store more data compared to traditional 1D barcodes.


In conclusion, understanding Code 93 unlocks a world of efficiency, security, and versatility in the realm of barcodes. From its sophisticated design to applications in logistics, retail, and postal services, Code 93 stands as a testament to technological advancement. 

As industries evolve, the symbology’s higher data density, compact size, and enhanced security features continue to make it a preferred choice. Stay tuned for emerging trends, and remember, whether navigating declines or selecting barcodes, informed choices empower your business.
