In the NDC, how many digits represent the manufacturer?

In the National Drug Code (NDC) format, the manufacturer is represented by a specific segment of the code. The NDC consists of three segments: the first segment indicates the labeler (usually the manufacturer), the second segment identifies the product (strength, dosage form, etc.), and the third segment denotes the package size.

The first segment, which represents the manufacturer or labeler, is comprised of 5 digits. This portion of the NDC is crucial because it uniquely identifies the company responsible for the product's production and labeling. Each manufacturer or labeler is assigned a unique code by the FDA, ensuring that there is no confusion in identifying different products from different manufacturers.

Understanding this structure is vital for anyone involved in pharmacy practice, as it helps in accurately interpreting drug information, ensuring proper medication dispensing, and tracking pharmaceutical products.
