๐ฆ SSCC-18 Shipping Container Code Generator
SSCC-18 is a GS1 Serial Shipping Container Code used to uniquely identify logistics units like pallets and cartons. The last of its 18 digits is a GS1 standard modulus-10 check digit.
Enter a 17-digit number combining an extension digit, GS1 company prefix, and serial reference, and this tool automatically computes the check digit to generate an SSCC-18 (Serial Shipping Container Code) barcode that uniquely identifies a logistics unit like a pallet or carton.
How to use
- Enter the 17-digit number combining the extension digit, GS1 company prefix, and serial reference.
- The check digit is calculated automatically to produce the 18-digit SSCC-18 barcode.
- Download the generated barcode as SVG or PNG.
FAQ
What is SSCC-18?
It's a GS1 standard: an 18-digit serial number that uniquely identifies an individual logistics unit (a shipping container) like a pallet or carton. It's widely used in warehouse management and shipment tracking (ASN).
Why does entering 17 digits produce an 18-digit code?
The 17 digits you enter combine the extension digit, GS1 company prefix, and serial reference. A single check digit, computed using the GS1 standard modulus-10 algorithm (alternating weights of 3 and 1), is appended to produce the full 18-digit SSCC-18.
How is this different from the GS1-128 generator?
SSCC-18 is a specific data element commonly used within GS1-128 barcodes under Application Identifier (00). This tool encodes SSCC data directly with the (00) AI prefix, dedicated to that use case.
