Drug Establishment Registration & NDC Labeler Code: A Complete Guide

Overview: FDA Drug Establishment Requirements

Any establishment engaged in the manufacture, preparation, propagation, compounding, or processing of a drug product for commercial distribution in the United States must register with the FDA under 21 CFR Part 207. This applies to both domestic and foreign establishments.

Drug establishment registration is required annually — unlike food facility registration which is biennial. The registration window is October 1 – December 31 each year.

Who Must Register?

The following types of establishments must register:

• Manufacturers of finished drug products (prescription and OTC)
• Active Pharmaceutical Ingredient (API) manufacturers
• Repackers and relabelers of drug products
• Contract manufacturers and outsourcing facilities
• Salvagers of drug products
• Establishments that test finished drugs before release

What Is an NDC Labeler Code?

The National Drug Code (NDC) is a unique 10-digit numeric identifier for each drug product marketed in the United States. It consists of three segments:

• Labeler Code (4–5 digits): Identifies the firm that manufactures, repacks, or distributes the drug
• Product Code (3–4 digits): Identifies the specific strength, dosage form, and formulation
• Package Code (1–2 digits): Identifies the package type and size

To obtain an NDC labeler code, you must first complete establishment registration. The FDA assigns labeler codes as part of the registration process.

Drug Listing Requirements

In addition to establishment registration, every drug establishment must list each drug product it manufactures using FDA Form 3480 (for paper submissions) or via the electronic SPL (Structured Product Labeling) system. Drug listing must include:

• The drug's established name and trade name
• The NDC number
• Active and inactive ingredient list
• Dosage form and route of administration
• Labeler code and product/package codes
• Complete product labeling

Step-by-Step Registration Process

1. 1
   Designate a U.S. Agent All foreign drug establishments must have a U.S. Agent before registering. The U.S. Agent facilitates communications with the FDA and must be reachable during U.S. business hours.
2. 2
   Create an FDA ESG account Electronic submissions to FDA are made through the FDA Electronic Submissions Gateway (ESG). You will need an account and appropriate software to submit SPL files.
3. 3
   Submit establishment registration via SPL Submit your establishment registration using the FDA's electronic Structured Product Labeling format. This requires specialized software or a regulatory consultant.
4. 4
   Receive DUNS and FEI numbers Upon registration, you receive a Data Universal Numbering System (DUNS) number and an FDA Establishment Identifier (FEI). These are needed for all future FDA interactions.
5. 5
   Submit drug listings After establishment registration, submit individual drug product listings for each product you intend to market. Listings must be updated whenever product information changes and re-submitted annually.

Annual Renewal Requirements

Drug establishment registrations must be renewed annually between October 1 and December 31. Unlike food facility registration, there is no grace period — a lapsed drug establishment registration means you cannot legally market drugs in the U.S. until renewed.

Drug listings must also be updated at the time of registration renewal, including notification of any drugs discontinued since the last update.
