Which part of the NDC number indicates the manufacturer of a drug?

the first 4-5 digits.
the product code
the second segment
the last 1-2 digits

The correct answer is: the first 4-5 digits.

The first 4-5 digits of an NDC (National Drug Code) number indicate the manufacturer of a drug. This is known as the labeler code or the first segment of the NDC number. This code is assigned by the FDA to identify the specific manufacturer of the drug. The manufacturer's name and contact information can be found by looking up their assigned labeler code on the FDA's National Drug Code Directory. The other options, such as the product code (B), second segment (C), and last 1-2 digits (D) do not indicate the manufacturer of the drug, but rather provide information about the specific product, package size, and/or package type. Therefore, they are not the correct options for indicating the manufacturer of a drug.
