National Drug Code (NDC)

What is a National Drug Code (NDC)?
The NDC, or National Drug Code, is a unique 10-digit or 11-digit, 3-segment number, and a universal product identifier for human drugs in the United States.

The 3 segments of the NDC identify: the labeler, the product, and the commercial package size.

  • The first set of numbers in the NDC identifies the labeler, such as the drug manufacturer, repackager, or distributor.
  • The second set of numbers is the product code, which identifies the specific strength, dosage form (i.e, capsule, tablet, liquid) and formulation of a drug for a specific labeler.
  • Finally, the third set is the package code, which identifies package sizes and types.
