Colombia's regulations mandate unique identification for all pharmaceutical products using GS1 standards, including GTIN (Global Trade Item Number), lot number, serial number, and expiration date. The system employs GS1 DataMatrix barcodes, selected for their capacity to encode substantial information within a compact space - a critical feature for marking individual medication units and enabling reliable authentication at each point in the supply chain.

The Colombian traceability framework demands comprehensive visibility across all supply chain touchpoints. Every stakeholder - manufacturers, importers, distributors, and pharmacies - must participate in the system by capturing and recording product data at each transaction stage. This integrated approach ensures unbroken traceability from factory floor to patient, creating a transparent ecosystem that safeguards against counterfeit products and unauthorized diversions.

INVIMA implements robust compliance monitoring through systematic inspections and post-market surveillance activities. Under Law 1122 of 2007, the institute has statutory authority to enforce traceability requirements, conduct facility audits, and implement corrective actions when necessary. The regulatory framework includes significant consequences for non-compliance, reinforcing the importance of adherence to established standards and protecting public health interests.

Colombia's system is progressively transitioning from manual, barcode-based procedures to more sophisticated, automated digital solutions. The regulations specify that traceability systems must ensure data security and integrity while supporting automated data capture technologies. This digital transformation enhances the efficiency of product verification, streamlines regulatory reporting, and creates opportunities for consumer-facing applications that provide legitimate product information to patients.
