Everything you should Know about NDCs (National Drug Codes)

National Drug Codes (NDCs) can be a confusing topic, but with the right knowledge, you can understand their purpose and use them correctly. Our regulatory consultants will help you sort out the details about NDCs, including what they mean, how to interpret them, and the regulations that come with using them. Click here to learn why NDC Numbers have a massive impact on the pharmaceutical industry.

What Are National Drug Codes?

National Drug Codes (NDCs) are numbers issued by the FDA to identify specific drug products and packages. They are used to keep track of prescription and over-the-counter medications and can help doctors, pharmacists, manufacturers, payers, and other healthcare professionals determine what drug is being prescribed or dispensed. NDCs come in two basic formats — a 10-digit NDC or an 11-digit NDC.


How Are NDCs Used?

NDCs are used to identify drug products in many different ways. For example, the 11-digit format is often used for billing purposes, while the 10-digit format can be used for ordering and reporting purposes. NDCs can also be used in electronic health records (EHR) systems to help track and compare medication use patterns. The NDC also serves as a key identifier when tracking pharmaceuticals across the supply chain. This helps ensure that medications are safe, effective, and properly labeled throughout their entire lifespan.

What Do NDC Numbers Look Like?

NDC numbers are made up of several components. An 11-digital NDC number is broken down into three separate parts; the labeler code (which identifies the manufacturer), a product code, and package size. The 10-digit format eliminates the package size and count part and only includes the labeler code and product code. The length of an NDC number can vary depending on whether it is for an individual or multiple items, so make sure to double-check the format you need before using an NDC on your product labels.

What Types of Drugs Require an NDC Number?

All drugs and biologics that are regulated by the FDA must include an NDC number on their label, including prescription drugs, over-the-counter medicines, and medical devices. However, not all products are required to have an NDC; dietary supplements and herbal remedies do not fall under this regulatory requirement. Additionally, some non-FDA-approved substances like homeopathic medicines may be exempt from needing an NDC code.

What are the Implications of an Incorrect NDC Number?

Incorrect NDC numbers can be problematic and have several implications. An incorrect code could be fraudulent, indicating that patients are receiving a counterfeit version of the product instead of the authentic version. Additionally, an inaccurate NDC may lead to insurance fraud if the product is billed against a code that doesn’t match the administered drug or biologic. Finally, incorrect use of NDCs could also create big issues with pharmaceutical data exchange centers, which are used to confirm eligibility for financial and other benefits programs.


Wondering how to get an NDC Number?

OTC drugs sold in the United States must be labeled with a National Drug Code (NDC). This number on a product label shows that the medicine has satisfied all quality, safety, and efficacy standards. Any firm wanting to manufacture OTCs in the United States must guarantee that their product fulfills the criteria for safety and efficacy. They should check to see whether they are in compliance with GMPs and fulfills the labeling criteria outlined in 21 CFR part 201.66. In many circumstances, satisfying FDA standards can be a complicated task. Quality Smart Solutions can assist you in precisely and effectively preparing your OTC product registration and obtaining an NDC number for your product.
