Updated November 6, 2026. Read from US Food and Drug Administration, National Drug Code Directory (openFDA). CC0 1.0 public domain dedication (openFDA). Counts are products in the FDA National Drug Code Directory on November 6, 2026: 138,262 products in commercial distribution, meaning without a marketing end date in the past. A company is a labeler code; one company can hold several codes, and the directory carries no address. Inclusion in the directory is not FDA approval, and the marketing category says under which kind of application or rule a product is sold.
