Serialization & Track-and-Trace with Barcodes

Serialization assigns a unique identifier to each individual item (not just each product type), enabling track-and-trace visibility from manufacturing through distribution to the end consumer. Barcode-based serialization is now mandated in pharmaceuticals and expanding into food and other regulated industries.

From Batch to Item-Level Identification

Traditional barcodes identify a product type (GS1 Standards & Identifiers">GTIN). Every bottle of the same medicine has the same barcode. Serialization adds a unique serial number to each individual bottle, enabling:

• Traceability: Track each unit's journey through the supply chain
• Authentication: Verify a product is genuine at any point
• Recall management: Identify exactly which units are affected
• Diversion detection: Spot products appearing in unauthorized channels

GS1 Serialization Standard

The GS1 system encodes serialized data using Application Identifiers:

(01)09506000134352(21)ABC12345(17)260630(10)LOT-X
     GTIN              Serial     Expiry      Batch

This combination of GTIN + Serial + Batch + Expiry is often called the "four key data elements" in pharma serialization.

SGTIN: Serialized GTIN

An SGTIN combines a GTIN with a serial number to create a globally unique item identifier. In RFID systems, SGTINs are encoded in EPC (Electronic Product Code) format. In barcode systems, SGTIN data is carried by AI(01) + AI(21).

Encoding in Barcodes

Serialized data is typically encoded in:

• GS1 DataMatrix: Preferred for pharmaceuticals due to small size and high capacity
• GS1-128: Used on case and pallet labels
• QR Code with GS1 Digital Link: Emerging format for consumer interaction

Event-Based Traceability

The Electronic Product Code Information Services (EPCIS) standard records "what, where, when, why" events:

Each event captures the serialized barcode data, location, timestamp, and business context.

Regulatory Drivers

Anti-Counterfeiting

Serialization enables point-of-dispense verification. A pharmacist scans the barcode, and the serial number is checked against a central database. If the serial number is unknown, already dispensed, or flagged, the system alerts the pharmacist to a potential counterfeit.

Implementation Challenges

• Serial number generation: Must be random (not sequential) to prevent prediction
• Data management: Billions of serial numbers require robust database infrastructure
• Line integration: Production lines need cameras, printers, and rejection mechanisms
• Interoperability: All supply chain partners must exchange serial-level data
