The FDA is moving every National Drug Code (NDC) to one 12-digit format. The rule takes effect on March 7, 2033[1]. Use this checklist to see what your pharmacy needs to ask, test and teach before then.
An NDC is the number that identifies a drug product and its package. Today the FDA assigns NDCs that are 10 digits long, in more than one layout[1]. Under the final rule published on March 5, 2026, every FDA-assigned NDC will be 12 digits in one layout: 6 digits for the company, 4 for the product and 2 for the package[2].
On March 7, 2033, the FDA will start assigning 12-digit NDCs and will convert every existing 10-digit NDC to the 12-digit format[1]. The FDA asks pharmacies, payers and the rest of the supply chain to start preparing as soon as possible[1].

The price files, catalogs and invoices you receive from the companies you buy from.
How prescriptions are billed to insurance plans and how you prove a claim was right later.
