Introduction
Pharmaceutical products often travel across multiple countries and regulatory environments before reaching their final destination—the patient. While this global movement enables wider access to medicines, it also introduces significant vulnerabilities. Even a single weak link in the supply chain can allow counterfeit, falsified, or sub-standard drugs to enter circulation, posing severe risks to patient safety and eroding trust in pharmaceutical brands. For manufacturing and export-driven markets such as India, where pharmaceutical volumes are high and global distribution is extensive, ensuring supply chain transparency is critical. As regulatory scrutiny increases worldwide, the demand for end-to-end visibility has become a strategic priority. Track and trace systems play a pivotal role in addressing these challenges by enabling transparency, accountability, and confidence throughout the pharmaceutical supply chain.
Why Track and Trace Has Become Essential in the Pharmaceutical Industry
Counterfeit medicines remain one of the most pressing threats to global healthcare. The World Health Organization (WHO) defines counterfeit medicines as those that are deliberately and fraudulently mislabelled with respect to identity or source. These products may contain incorrect quantities of active ingredients, harmful substances, or no active ingredients at all—often packaged to appear authentic. The consequences of counterfeit and sub-standard medicines can be devastating, leading to treatment failures, drug resistance, serious illness, or even death. To counter this risk, governments and regulatory authorities across the globe are mandating serialization and traceability across pharmaceutical supply chains.
An effective track and trace system delivers several critical advantages:
- Regulatory Compliance: Helps manufacturers and distributors meet national and international regulatory requirements.
- Reduced Financial Risk: Minimizes losses due to recalls, theft, diversion, and grey-market activity.
- Brand Protection: Enhances credibility and trust by demonstrating transparency and accountability.
- Improved Patient Safety: Ensures that only genuine, high-quality medicines reach patients.
Without robust traceability mechanisms, pharmaceutical supply chains remain opaque and highly susceptible to regulatory intervention and reputational damage.
What Does Track and Trace Mean in Pharmaceuticals?
In the pharmaceutical context, track and trace refers to the ability to monitor a medicine’s movement throughout its lifecycle and verify its authenticity at every stage.
- Tracking involves recording each point where a product changes hands—from the manufacturer to distributors, wholesalers, pharmacies, and healthcare providers. This enables stakeholders to know where a product is at any given time.
- Tracing allows stakeholders to look backward through the supply chain to identify the origin and movement history of a specific product. This capability is crucial during product recalls or investigations into suspected counterfeit activity.
Both functions depend on standardized, unique identification of products and logistics units. Global Trade Item Numbers (GTINs), encoded in 1D barcodes or 2D GS1 DataMatrix symbols, provide a common language for product identification. This standardization ensures interoperability between systems, reduces manual errors, and supports seamless data exchange across the supply chain.
How GS1 Standards Enable Pharmaceutical Traceability
GS1 standards form the foundation of effective track and trace systems by providing globally recognized identification keys and data-sharing frameworks. The most widely used GS1 identification keys in pharmaceutical traceability include:
- GTIN (Global Trade Item Number): Uniquely identifies pharmaceutical products at all packaging levels.
- SSCC (Serial Shipping Container Code): Identifies logistic units such as pallets and cases.
- GLN (Global Location Number): Identifies physical locations and legal entities within the supply chain.
These identifiers ensure consistent and accurate product and location identification from manufacturing through distribution to dispensing. However, identification alone is not sufficient. GS1 standards work together with advanced data capture and information-sharing mechanisms to enable complete traceability.

How Pharmaceutical Track and Trace Works in Practice
1. Serialized Identification: Each pharmaceutical product is assigned a unique serial number linked to a GTIN at the primary, secondary, and tertiary packaging levels. Logistics units are identified using SSCCs, enabling item-level visibility throughout the supply chain.
2. Data Capture Using GS1 DataMatrix: GS1 DataMatrix barcodes are widely used in healthcare due to their ability to store large amounts of data in a compact space. These barcodes encode critical information such as GTIN, batch or lot number, serial number, and expiry date, meeting both regulatory and operational requirements.
3. EPCIS for Event Visibility: Electronic Product Code Information Services (EPCIS) enables organizations to capture and share event data related to product movement. EPCIS answers four key questions—what, when, where, and why—providing real-time visibility into the journey of pharmaceutical products across the supply chain.Together, serialized identifiers, DataMatrix barcodes, and EPCIS create a powerful ecosystem for end-to-end pharmaceutical traceability
Benefits of GS1-Based Track and Trace Systems
Implementing GS1-enabled track and trace solutions delivers value far beyond compliance:
- Improved Patient Safety: Significantly reduces the risk of counterfeit or expired medicines reaching patients.
- Operational Efficiency: Standardized identification and automation streamline supply chain processes and reduce administrative burden.
- Faster, Targeted Recalls: Enables quick identification and removal of affected products, minimizing disruption and risk.
- Stronger Stakeholder Trust: Demonstrates commitment to transparency, quality, and regulatory adherence.
Conclusion
In an increasingly complex and globalized pharmaceutical ecosystem, ensuring the authenticity, safety, and integrity of medicines is paramount. Track and trace systems, powered by GS1 standards, provide the visibility and control required to protect patients, comply with regulations, and strengthen supply chain resilience. By adopting standardized identification, advanced data capture, and real-time information sharing, pharmaceutical companies can move beyond reactive compliance toward proactive risk management. As regulatory expectations continue to evolve, embracing GS1-based track and trace solutions will be essential for building safer, more transparent, and more trusted pharmaceutical supply chains worldwide.
