Code 93 is a one-dimensional barcode symbology. It has a high data density and can encode more data in a smaller space than other barcodes. This article will explore its specifications, applications, how it compares to Code 39, and guides you through generating your Code 93 barcode.

What is Code 93?

Code 93 was invented in 1982 by INTERMEC to achieve better information densities (compared to Code 39).

Code 93 gets its name from its structure: every character is nine modules wide, comprised of three bars and three spaces. It’s a continuous, variable-length barcode symbology, is used extensively in shipping and inventory management. 

Code 93 is a high-density, alphanumeric barcode with the capability to encode 47 characters, including uppercase letters, numbers, and a few special characters.

Building on Code 93, Code 93 Extended handles the full ASCII set using a special control character to switch into an expanded encoding table.

What is the Difference Between Code 93 and Other Barcode Types?

1. Code 93 vs. Code 39

What is the difference between Code 93 and Code 39? 

The key difference between Code 93 and Code 39 is their character sets. Code 93 can encode a broader range of characters, including uppercase letters, numbers, and special characters. 

In contrast, Code 39 is limited to 43 characters, omitting lowercase letters and some special characters.

Code 93 boasts a more compact design, allowing for denser information encoding within a smaller space. However, it forgoes Code 39's simpler self-checking mechanism to accommodate a wider character set.

2. Code 93 vs. Code 128

Compared to Code 128, which uses a variable-length format and can encode the full ASCII 128-character set, Code 93 has a narrower character set but greater density. This makes Code 93 more suitable for applications requiring high-density and variable-length barcodes.

What are the Applications of Code 93?

What is Code 93 used for? It is used in the military, the automobile industry, and by Canada Post to encode specific delivery information.

Here are some applications of Code 93:

1. Package Tracking

Postal services, such as Canada Post, employ Code 93 barcodes to encode supplementary delivery information on packages. 

2. Inventory Management

Code 93 is utilized by manufacturing companies to track inventory levels and movements of raw materials, components, and finished products within their facilities. Each item can be labeled with a Code 93 barcode, allowing for efficient scanning and updating of inventory databases.

3. Automotive Parts Identification 

In the automotive industry, Code 93 barcodes are often used to label individual parts and components. 

4. Healthcare

Code 93 barcodes are utilized in various industries, including healthcare, for purposes such as medication identification and tracking, patient identification, and inventory management. Code 93 contributes to accurate medication administration and streamlined inventory processes.

5. Manufacturing

In manufacturing, Code 93 barcodes are commonly utilized for various purposes, including asset tracking, product identification. 

Manufacturers employ Code 93 barcodes on components, raw materials, finished products, and equipment to streamline production processes, monitor inventory levels, and ensure traceability throughout the supply chain.

Step 4: Download and Save the Barcode

Get your barcode in the format you need! While it's saved as a PNG by default, you can choose from several formats you need. This will allow you to use the barcode image in various applications as needed.

By following these steps, you can effectively generate a Code 93 barcode using Online Tool Center barcode generator.  

Step 5: Check the Barcode

In general, barcode scanners are used to verify barcodes.

Tips for Printing and Scanning Code 93 Barcodes

In the transportation, logistics, healthcare, and manufacturing sectors, manufacturers often opt for high-quality barcode printers to print Code 39 barcode labels. This ensures the precise and accurate replication of the barcode's narrow bars and spaces, a critical factor for reliable scanning.

In addition, the following factors should also be considered:

● Code 93 requires a quiet zone that is at least the width of ten narrow bars. The bar height should be at least 15 percent of the symbol length or 0.25 inches (6.4 mm), whichever measurement is larger.

● Check the contrast between the bars and the background of the barcode. Avoid using colors that are too similar, as this may affect the barcode's scannability.

When choosing a 1D barcode scanner for reading Code 93 barcodes, search for models with quick scanning and decoding speeds, and ensure the scanning distance meets your application requirements.

For use in a wide range of working situations, look for scanners that are highly durable, water-resistant, and dust-resistant. 

In addition, ensure compatibility by selecting the suitable interface type for seamless connection with your current systems.
