What identifying code format is used for the National Drug Code (NDC)?

The National Drug Code (NDC) uses a specific format that consists of three segments of numbers, which is represented as XXXXX-XXXX-XX. The first segment, which consists of five digits, identifies the labeler or manufacturer of the drug. The second segment, consisting of four digits, identifies the specific product, including the formulation and strength. The final segment, made up of two digits, is used to specify the package size or type. This consistent format allows for precise identification of drugs in the marketplace, which is crucial for proper dispensing, record-keeping, and ensuring patient safety.

Understanding this structure is essential for pharmacy professionals because accurate recognition and documentation of the NDC is a fundamental part of pharmaceutical practice, ensuring compliance with regulations and aiding in medication safety.
