FDA NDC Number Reservation Made Easy: A Comprehensive Guide to Drug Identification and Compliance

FDA NDC Number Reservation: An overview

All drug establishments must provide the Food and Drug Administration (FDA) with a list of all drugs they manufacture, prepare, propagate, compound, or process for commercial distribution. The FDA uses a unique, three-segment number called the National Drug Code (NDC) to identify and report drug products.

The NDC is a universal product identifier for human drugs. A registered establishment must update its drug listing data in June and December of each year. The listing information is to be submitted electronically.

Products Covered in the FDA NDC Number Directory

The FDA NDC Number Directory lists prescription drugs, OTC drugs, and insulin products that have been manufactured, prepared, propagated, compounded, or processed by registered establishments for commercial distribution in the US.

Products not Covered in the FDA NDC Number Directory

The NDC Directory does not list those products which are;

  • If the products are not prescription drugs, OTC, or insulin products.
  • If the products are no longer being marketed;
  • If the manufacturer has not provided complete information about the product.

Information Required for FDA NDC Reservation

Product Trade Name or Catalog Name

Product names in the NDC Directory are limited to 100 characters. Some information may be omitted from product names, such as strength, USP/NF designations, and trademark symbols.

NDC Number

The FDA NDC (National Drug Code) is a unique 10-digit number assigned to each listed drug product. It identifies the labeler, product, and package size. The first segment is the labeler code assigned by the FDA, the second segment is the product code indicating strength and dosage form, and the third segment is the package code specifying package sizes and types.

Dosage Form

The dosage form refers to how a medication is prepared and presented for administration. It encompasses various physical formats such as tablets, capsules, liquids, creams, injections, and more.

Routes of Administration

Routes of administration are the different ways medications enter the body, including oral (by mouth), topical (on the skin), injectable (via injections), inhalation (breathed in), transdermal (through the skin), rectal (via the rectum), and nasal (through the nose) etc. The chosen route depends on the medication's properties, desired effects, patient's condition, and convenience. Each route has specific advantages in terms of absorption, onset of action, and distribution.

Active Ingredient(s)

The active ingredient refers to the key component or substance in a medication or product that produces its intended therapeutic effect.


Strength refers to the concentration or potency of the active ingredient in a medication or product. It indicates the amount of the active ingredient present per unit of dosage or volume.


Unit refers to the specific measurement or quantity in which a medication or substance is dosed or administered. It can vary depending on the context, such as milligrams (mg), micrograms (mcg), milliliters (mL), grams (g), or units specific to certain medications or substances. The unit of measurement is used to ensure accurate dosing and administration of the medication or substance.

Package Size and Type

Package size refers to the quantity or amount of a product contained within its packaging. It indicates the total volume, weight, or count of individual units in a package. The package size can vary depending on the product and its intended use. Package type refers to the physical form or presentation of the packaging itself. It includes various formats such as bottles, blister packs, tubes, vials, jars, sachets, boxes, or other specific packaging designs. The package type is chosen based on factors such as product protection, convenience, storage requirements, and regulatory guidelines.

Major Drug Class

Major drug classes refer to broad categories or groups of medications that share similar mechanisms of action or therapeutic uses. Examples of major drug classes include antibiotics, antihypertensives, antidiabetic agents, analgesics, antidepressants, anticoagulants, and antihistamines. These classes help categorize and classify medications based on their primary pharmacological effects and clinical indications.

FDA Approved Application Number

The NDA/ANDA number is assigned to a product approved by the FDA after assessing its safety, effectiveness, manufacturing processes, packaging, and labeling. This number indicates that the drug has met the necessary criteria for marketing approval.

Example of FDA NDC Number


In conclusion, the FDA NDC Number plays a crucial role in tracking and managing drug products. The NDC Directory serves as a valuable resource for healthcare providers, pharmacists, payers, and patients, providing essential information about drugs, including their names, dosage forms, strengths, routes of administration, active ingredients, and package details. By utilizing the NDC Directory, stakeholders can ensure the accuracy and safety of drug prescribing, dispensing, utilization tracking, and patient education.
