NDC Data -- National Drug Code Data
The FDA descibes the National Drug Code Data in the following way:
"The Drug Listing Act of 1972 requires registered drug establishments to provide the Food and Drug Administration (FDA) with a current list of all drugs manufactured, prepared, propagated, compounded, or processed by it for commercial distribution. (See Section 510 of the Federal Food, Drug, and Cosmetic Act (Act) (21 U.S.C. § 360)). Drug products are identified and reported using a unique, three-segment number, called the National Drug Code (NDC), which serves as a universal product identifier for drugs. FDA publishes the listed NDC numbers and the information submitted as part of the listing information in the NDC Directory which is updated daily. The information submitted as part of the listing process, the NDC number, and the NDC Directory are used in the implementation and enforcement of the Act."
The FDA offers an NDC searchable database.
The National Drug Code (NDC) Directory data is offered here in SAS, Stata, and CSV formats to make the whole database a bit easier to use.
Some additional historic files are available in the CCYY/CCYYMMDD folders where CCYY is the year, MM is the month, and DD is the day.
