Vocabulary Work Group

Maturity Level: 2

The National Drug Codes (NDC) and National Health Related Items Code (NHRIC) codes are codes issued by the FDA for tracking drugs and devices. Note that the NHRIC codes are being replaced by the UDI system .

4.3.10.2 Version Issues

The FDA published list of NDC codes for finished drug products is updated daily. Use the format YYYYMMDD to refer to a particular distribution. Note that while only valid NDC codes appear in the distribution file, there are other NDC codes that organizations have assigned but not yet reported to FDA. Therefore, the full set of NDCs that exists in the marketplace is unknown and cannot be versioned completely.

4.3.10.3 Copyright/License Issues

NDC codes have no copyright acknowledgment or license requirements.
