Which statement accurately describes the NDC number?

• A. The NDC, or National Drug Code, is a unique 10-digit, 3-segment number that serves as the universal product identifier for human drugs in the United States and appears on all prescription and OTC packages.
• B. The NDC is a 12-digit code used only for veterinary products.
• C. A 9-digit code used to track dietary supplements.
• D. An 11-digit code used for device components.

Answer: (A)

The NDC is the National Drug Code, the universal product identifier assigned to human drug products in the United States. It is a unique 10-digit number divided into three segments that identify the labeler (the company that markets the product), the product, and the packaging. This three-part structure lets pharmacists, insurers, and regulators precisely pinpoint a specific drug and its packaging. The NDC appears on all prescription and over-the-counter drug packages, supporting accurate dispensing, inventory control, and claims processing. You may see the code shown with or without hyphens, and sometimes it’s presented as 11 digits if a leading zero is added for padding, but the core idea remains: it uniquely identifies a human drug product in the U.S.

Other codes described as veterinary-only, dietary-supplement-specific, or device-component identifiers don’t match the NDC’s purpose or scope, which is focused on human drug products and their packaging rather than veterinary products, dietary supplements, or medical devices.
