CVS Pharmacy Technician Certification Practice Test

During a pre-quality check, which NDC components must match?

1. The first 5 numbers

2. The last 2 numbers

3. The middle 4 numbers

4. The DEA number

The correct answer is: The middle 4 numbers

The correct answer highlights that during a pre-quality check, the middle four numbers of the National Drug Code (NDC) must match. The NDC is a unique identifier for medications in the United States, consisting of 11 digits arranged into three segments. These segments denote the labeler code, the product code, and the package code. The middle four numbers specifically represent the product code, which identifies the specific drug formulation and strength manufactured by the labeler. Ensuring these numbers match is crucial because it directly pertains to the specific characteristics of the medication, like its use and dosage form. If these numbers do not match, it may indicate a mix-up with the product being dispensed, potentially leading to patient safety issues. In contrast, the first five numbers indicate the labeler, and while they are important for identifying the manufacturer or distributor, they do not provide information about the specific drug. The last two numbers relate to the packaging size, and the DEA number is separate entirely, as it pertains to controlled substances rather than NDC specifics. Thus, matching the middle four numbers is essential for confirming that the correct medication will be provided to patients.
