SSCC Generator

Generates a compliant SSCC (Serial Shipping Container Code) for GS1 logistics. It accepts an extension digit, a GS1 company prefix, and a serial reference, then outputs an 18-digit SSCC with a calculated check digit. The 17-digit base is formed from the concatenation of the extension, prefix, and serial reference, after which the check digit is derived using a modulo-10 algorithm. This tool enforces GS1-128 compatibility and is suitable for labeling pallets, containers, and intermodal shipments. It is designed for use by logistics teams, warehouse operators, and carriers to ensure consistent, auditable identifiers across the supply chain. The SSCC can be embedded in barcodes downstream or included in shipment documentation for traceability and auditing. The value arises from deterministic generation, input validation, and production of a standards-compliant code that aligns with enterprise serialization plans. The tool focuses on correct data assembly and formatting, minimizing labeling errors and enabling seamless integration with existing tracking workflows. It does not allocate prefixes, create physical barcodes, or verify prefix uniqueness; those tasks are outside its scope and rely on GS1 administration and downstream systems.
