4.2.10.2 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.

NDC codes have no copyright acknnowledgment or license requirements.
