Supply Chain Optimization: Serialization
and Aggregation with GS1 Standards

The serialization, essential for the unique identification of products in the supply chain, is carried out through the assignment of a code consisting of an NTIN (National Trade Item Number) or GTIN (Global Trade Item Number) and a Serial Number. The global adoption of the GS1 standard has enhanced this process, ensuring the accessibility and accuracy of crucial information throughout the entire supply chain

With 11 GS1 identification keys, such as GTIN, GLN, and SSCC, accurate management of information is crucial. The GTIN, for example, is a 14-digit code, including an indicator, GS1 company prefix, product code, and check digit. This ensures the distinction between products with different characteristics

The use of AI allows the encoding of specific information, such as the manufacturing date and serial number, providing a detailed and organized view

Commissioned refers to the product that has been assigned a serial number, verified as suitable, and associated within the system to ensure its uniqueness. De-commissioned refers to the product that, during the verification process, has been discarded due to issues such as poor quality of printed codes, character recognition (OCR) issues with 'Human Readable' text, or internal system errors.

GS1 barcode families, such as EAN/UPC, DataBar, and 2D Barcodes (Datamatrix and QR Code), are adapted to specific applications within the supply chain.

By delving into the Datamatrix, a two-dimensional barcode, we examine its structure, Finder Pattern, and printing characteristics. Compliance with ISO/IEC 15415 parameters is essential to ensure its quality.

The aggregation process links smaller units to larger units within the supply chain. Different types of units, such as cartons, packing boxes, and pallets, are involved in this process, providing greater traceability and optimized management.

The Chinese Ministry of Health guidelines specify the use of the EAN 128C code for cartons, bundles, and packing boxes.

The implementation of GS1 standards for serialization and aggregation revolutionizes supply chain management, improving efficiency and visibility. Accuracy in product identification, the print quality of linear barcodes ISO/IEC 15416, and compliance with standards are crucial for a robust and reliable system
