What does the package code segment of the NDC identify?

The package code segment of the National Drug Code (NDC) specifically identifies the package form and sizes of the drug. The NDC is a unique identifier for medications, providing key information in three segments: the labeler code (identifying the manufacturer), the product code (specifying the drug’s strength, dosage form, and formulation), and the package code, which reveals details about the package type and size, such as whether the drug is in a bottle, box, or any other packaging format.

This distinction is crucial as it enables pharmacists, healthcare providers, and patients to easily identify how the medication is packaged, which can influence dispensing practices and patient adherence to medication regimens. Understanding package details is particularly important for ensuring accurate dispensing and reducing medication errors.
