What section of the NDC identifies the manufacturer?

The first section of the National Drug Code (NDC) is specifically designated to identify the labeler, which typically refers to the manufacturer or distributor of the medication. The NDC is composed of a three-segment number usually formatted as 5-4-2 digits. The first segment, containing 5 digits, reveals the identity of the company that manufactures or distributes the drug product, making it essential for recognizing the responsible party for that medication. This information is critical in pharmacy practice as it helps pharmacists verify the source of the medication and ensures patient safety by allowing for recalls and tracking purposes when necessary. Understanding this structure is crucial for anyone involved in pharmacy operations or education.
