The FDA's move to a 12-digit NDC looks, on the surface, like a label update. It isn't.
By March 2033, every NDC on a US drug label, Rx and OTC, moves to a single 12-digit format (6-4-2). The deadline is fixed and the FDA has been clear there's no extension. What's less clear to most teams is how far this reaches: it touches the barcode your lines print and read, the master data behind every SKU, and systems well downstream of the label, often riding directly on the DSCSA serialization foundation many manufacturers stood up back in 2023–24.
