NDC Codes by Labeler / Manufacturer
The labeler is the company responsible for a drug's label: a manufacturer, repackager, relabeler or private-label distributor. Its NDC labeler code is the first segment of every NDC it lists.
Labeler codes
The FDA assigns each labeler a four- or five-digit code, which forms the first segment of its NDCs. Some companies hold several codes, and a repackager lists products it did not make under its own code. See labeler code and the curated manufacturer hubs.
