In the NDC, which segment indicates the package size?

• A. First segment
• B. Second segment
• C. Third segment
• D. All segments combined

Answer: (D)

The main idea here is that the National Drug Code is divided into three segments, each with a specific role. The first segment identifies the labeler or manufacturer. The second segment identifies the product itself (the drug, strength, and dosage form). The third segment is the one that specifies the package size or packaging configuration — for example, how many units are in the package or the type of primary container. So, the package size is encoded in the third segment of the NDC, while the first two segments define who makes the product and exactly which product it is. The full NDC may be written with different digit groupings, but the third segment consistently represents the packaging size.
