What Is the Ideal Size for an SSCC Barcode?

The ideal size for an SSCC barcode ensures it is easily scannable and adheres to GS1 standards. When printed using GS1-128 symbology, the recommended x-dimension (the width of the narrowest bar) ranges from 0.495 mm to 0.94 mm, depending on the intended application and scanning environment.
The barcode’s height should ideally be 32 mm, with a minimum height of 13 mm permissible if space constraints exist. Quiet zones—the blank spaces on either side of the barcode—must be at least 10 times the x-dimension to ensure proper scanning. These quiet zones act as a buffer to prevent reading errors.
Typically, SSCC barcodes are included on shipping labels sized around 4 x 6 inches, providing adequate space for the barcode, human-readable information, and additional data. Adhering to these guidelines ensures compatibility with global supply chains and smooth scanning across diverse environments.
How To Use Our Free SSCC Barcode Generator?

Our free SSCC Barcode Generator is simple and easy to use. Just input the required 18-digit Serial Shipping Container Code (including the check digit). SSCC barcodes accept only numeric data, so ensure accuracy when entering the code.
Once entered, click “Generate SSCC Barcode.” The barcode image will be generated instantly.
You can download the barcode in multiple formats, including PDF, SVG, PNG, or JPG, making it suitable for printing on shipping labels or integrating into digital systems.
How is the Checksum Calculated for an SSCC Barcode?

The checksum for an SSCC barcode is calculated using the GS1 Mod 10 algorithm. Follow these steps to compute the checksum:
Start with the SSCC base, excluding the check digit.
Assign alternating weights of 3 and 1 to each digit, starting from the rightmost digit and moving left.
Multiply each digit by its assigned weight.
Add up all the resulting values.
Calculate the sum modulo 10.
Subtract the result from 10 to determine the check digit. If the result is 10, the check digit is 0.
Combine the check digit with the SSCC base to complete the 18-digit SSCC.
Let’s understand this better with the help of an example.

7×3, 6×1, 5×3, 4×1, 3×3, 2×1, 1×3, 0×1, 9×3, 8×1, 7×3, 6×1, 5×3, 4×1, 3×3, 2×1, 1×3Multiply each digit by its assigned weight:
21, 6, 15, 4, 9, 2, 3, 0, 27, 8, 21, 6, 15, 4, 9, 2, 3Add up all the resulting values:
21 + 6 + 15 + 4 + 9 + 2 + 3 + 0 + 27 + 8 + 21 + 6 + 15 + 4 + 9 + 2 + 3 = 157Calculate the sum modulo 10:
157 mod 10 = 7Subtract the result from 10 to determine the check digit:
10 – 7 = 3Combine the check digit with the SSCC base to complete the 18-digit SSCC:

What is the Character Limit of Your SSCC Barcode Generator?

The SSCC Barcode Generator has a strict character limit of 18 digits, adhering to GS1 standards. This includes 17 data digits and 1 check digit, ensuring the barcode is valid and scannable. Only numeric characters (0-9) are accepted, as SSCC barcodes are strictly numeric.
The 18 digits consist of a single-digit extension, a GS1 company prefix, a unique serial reference, and a calculated check digit. The generator focuses exclusively on creating fully compliant SSCC barcodes, guaranteeing compatibility with global logistics and supply chain systems. By maintaining this fixed character limit, the generator ensures precision and adherence to industry requirements for reliable use in shipping and inventory management.
