NDC Express is an iPhone application developed by the Food and Drug Administration, falling under the Education & Reference category with a focus on Medicine. The app serves as a tool for identifying and reporting drug products using the National Drug Code (NDC) system, a unique 10-digit number composed of three segments.

The first segment, the labeler code, is assigned by the FDA to firms manufacturing or distributing the drug. The second segment, the product code, specifies details such as strength and dosage form, while the third segment, the package code, identifies package sizes. NDC Express streamlines the process of drug identification, ensuring compliance with FDA listing requirements and facilitating access to crucial drug information.
