National Drug Code (NDC)
The National Drug Code (NDC) is a unique identifier used to track and identify medications in the United States. It is an essential part of the pharmacy profession and plays a crucial role in various aspects of medication management, including dispensing, billing, and regulatory compliance.
What is the NDC?
The NDC is a 10-digit code (although sometimes written as 11 digits after formatting) that identifies a drug’s manufacturer, product, and packaging. It is a standardized code used to represent each drug in the U.S.The NDC is issued by the Food and Drug Administration (FDA) and is a key component in drug regulation, ensuring that medications are correctly identified and tracked.

Structure of the NDC
The NDC is typically divided into three segments:- Labeler Code (First 4 or 5 digits): Identifies the company or manufacturer of the drug.
- Product Code (Next 3 or 4 digits): Identifies the specific drug, including its strength, dosage form, and formulation.
- Package Code (Last 1 or 2 digits): Identifies the package size and type (e.g., bottle, blister pack).
NDC Format
While NDCs are officially a 10-digit code, they are often formatted into three segments, with leading zeros included to make the total 10 digits:- 4 or 5 digit labeler code (Unique code for a Manufacturer)
- 3 or 4 digit (product code)
- 1 or 2 digit package code (Identify package size)

NDC Number importance for Pharmacy Students
Identification of Medications:
The NDC helps identify medications accurately, ensuring that the correct drug is dispensed and administered to the patient. It differentiates between generic and brand-name drugs, as well as between various formulations of the same drug (e.g., tablet, injection, syrup).Drug Safety:
Pharmacists use the NDC to verify drug labels, helping to avoid medication errors, drug interactions, and misidentification of medications. The NDC also aids in recalls, allowing pharmacies to identify and remove affected products quickly.Inventory Management:
The NDC is used in inventory control systems to track medication stock levels, order medications, and manage dispensing accurately.Billing and Insurance:
The NDC is essential for insurance billing and reimbursement processes. It helps pharmacies submit claims to insurance providers and ensures that they are reimbursed for the specific medication dispensed.Regulatory Compliance:
The FDA mandates the use of NDC codes for reporting, drug labeling, and monitoring. The code helps the FDA and other regulatory bodies track medication usage and manage potential side effects.How Pharmacy Students Use the NDC
- During Dispensing: Pharmacy students must ensure the correct NDC is selected when filling prescriptions. This ensures that the exact medication, strength, and form are provided.
- In Drug Information: When researching drug information, NDC codes help verify specific formulations and track any relevant drug recalls.
- Pharmacy Systems: Pharmacy software uses the NDC to search for drug products, display drug information, and update inventory.
- Patient Counseling: Pharmacy students can use the NDC to help identify a patient’s medication in case of confusion regarding different formulations (e.g., different manufacturers for the same drug).
