As the U.S. drug supply chain grows more automated, the FDA is proposing a shift from the current 10- and 11-digit National Drug Code (NDC) formats to a standardized 12-digit structure. This change is driven by the looming exhaustion of 5-digit labeler codes and aims to enhance clarity, automation, and long-term sustainability. NDC 12 adopts a fixed 6-4-2 segment format, enabling better compatibility with GS1 standards, improved barcode readability, and seamless integration with traceability systems. The transition, expected to begin in 2025, will impact barcoding, GTINs, and data processing systems-requiring healthcare organizations to start preparing now.
