The US FDA NDC code<\/a><\/strong> plays a critical role in how drugs are identified, listed, distributed, and monitored in the United States. Whether you are a pharmaceutical manufacturer, distributor, importer, or regulatory professional, understanding the National Drug Code (NDC) system is essential for staying compliant with US FDA requirements and avoiding costly regulatory issues.<\/p>\n\n\n\n

What Is the US FDA NDC Code?<\/a><\/h2>\n\n\n\n

The National Drug Code (NDC)<\/strong> is a unique numeric identifier assigned to drug products listed with the United States Food and Drug Administration<\/strong>. It acts as a standardized way to identify prescription drugs, over-the-counter medicines, and certain biological products sold in the US market.<\/p>\n\n\n\n

Unlike approval numbers, the NDC does not<\/strong> indicate that a drug is approved or endorsed by the US FDA. Instead, it confirms that the product is properly listed<\/strong> and identifiable within the FDA\u2019s drug registration and listing system.<\/p>\n\n\n\n

Structure of the NDC Code<\/h2>\n\n\n\n

Traditionally, an NDC is a 10-digit code<\/a><\/strong> divided into three segments:<\/p>\n\n\n\n

    \n
  1. Labeler Code<\/strong> \u2013 Identifies the company that manufactures, repackages, or distributes the drug<\/li>\n\n\n\n
  2. Product Code<\/strong> \u2013 Identifies the specific drug, including strength and dosage form<\/li>\n\n\n\n
  3. Package Code<\/strong> \u2013 Identifies package size and type<\/li>\n<\/ol>\n\n\n\n

    Because different labelers use different segment lengths, the US FDA introduced the 11-digit NDC format<\/strong>. This standardized version is commonly required for billing, electronic claims, and database reporting.<\/p>\n\n\n\n

    10-Digit vs 11-Digit NDC Codes<\/h2>\n\n\n\n

    One of the most common questions is whether NDCs are 10 or 11 digits.<\/p>\n\n\n\n
