West Virginia MPJE (Pharmacy Jurisprudence) Practice Exam

What does the first segment of the NDC number represent?

1. Labeler (manufacturer) code

2. Package size and type

3. Product expiration date

4. Strength, dosage, and formulation

The correct answer is: Labeler (manufacturer) code

The first segment of the National Drug Code (NDC) number represents the labeler code, which is assigned to the manufacturer or distributor of the drug. This unique identifier allows for efficient tracking and identification of the various entities that produce or handle drug products. The labeler code is essential for the proper registration of drugs with the FDA and helps ensure accurate communication about the drug's source. The other segments of the NDC serve distinct purposes, such as identifying the specific product and its package size, but the labeler code is specifically intended to denote the manufacturer or distributor. Each labeler code is unique to a particular entity, ensuring that every product can be traced back to its origin for safety and regulatory compliance.
