Running a food, supplement, or cosmetic business that interfaces with US regulatory systems means navigating a sea of identification numbers and registrations. For many businesses, especially those new to importing or manufacturing FDA-regulated products, the differences between an FEI number, DUNS number, and FDA registration can be confusing.
Let’s clear up which identifier goes where and why each matters to your regulatory compliance.
Introduction
Whether you’re planning to export food products to the US, register a dietary supplement with the FDA, or start a cosmetics business, understanding identification requirements is crucial. These aren’t just bureaucratic hoops to jump through – they’re essential components of a regulatory framework designed to ensure product safety and facilitate commerce.
Each identifier – FEI, DUNS, and FDA registration – serves a unique purpose in different scenarios. Using the wrong identifier at the wrong time can lead to delays, rejected applications, or compliance issues that affect your bottom line.
Understanding FEI (Facility Establishment Identifier)
Purpose of FEI
The Facility Establishment Identifier (FEI) is an 8-digit number assigned by the FDA to identify specific facilities that manufacture, process, pack, or hold products regulated by the agency. Think of it as your facility’s FDA fingerprint.
Uses of FEI in Regulatory Compliance
Your FEI number becomes particularly important when: ✔️ Responding to FDA inspection findings ✔️ Submitting prior notice for imported food shipments ✔️ Filing product registrations or listings with the FDA ✔️ Tracking facility compliance history across multiple submissions The FEI number links all your FDA interactions to your specific facility, creating a regulatory history that follows your establishment.
Context in FDA Submissions
The FDA uses your FEI to track your facility in their systems. When you submit documents to the FDA through various portals like FURLS or PREDICT, the FEI helps them associate those submissions with your specific facility.
For example, when filing a Food Facility Registration, your assigned FEI becomes part of your permanent record with the FDA and will appear on inspection reports and other official communications.
Examples of Industries Required to Have an FEI
Industries that typically need an FEI include: ✔️ Food manufacturers and processors ✔️ Drug manufacturers ✔️ Medical device manufacturers ✔️ Dietary supplement facilities ✔️ Cosmetic producers ✔️ Food storage warehouses ✔️ Food importers Even if you’re based outside the US, your facility will need an FEI if you manufacture products that will be exported to the American market.
Understanding DUNS (Data Universal Numbering System)
Purpose of DUNS
Unlike the FEI, which is specifically for FDA purposes, the DUNS number (Data Universal Numbering System) is a unique nine-digit identifier issued by Dun & Bradstreet. It identifies businesses at a specific location and is used globally, not just in the US
Uses of DUNS for Business Credibility
Your DUNS number serves several important functions: ✔️ Establishes your business credit profile ✔️ Helps potential partners verify your business identity ✔️ Enables other companies to assess your financial stability ✔️ Creates a traceable business history Many companies won’t do business with suppliers who don’t have a DUNS number, making it essential for B2B transactions.
Role of DUNS in Government Contracting
If you want to do business with the US government or receive federal grants, a DUNS number is mandatory. It’s required for registration in the System for Award Management (SAM), which is the gateway to government contracts.
When DUNS is Required
You’ll need a DUNS number when: ✔️ Applying for government contracts ✔️ Seeking certain types of grants ✔️ Registering with the FDA in some contexts ✔️ Establishing business relationships with large corporations ✔️ Expanding internationally with certain partners For food importers, having a DUNS number can be particularly helpful for DUNS number requirements for US import processes, as many customs brokers and distributors will request it.
Understanding FDA Registration
Purpose of FDA Registration
FDA registration is the process of officially notifying the FDA about your facility and the regulated products you manufacture, process, pack, or hold. Unlike the FEI (which the FDA assigns to you) or DUNS (which D&B issues), FDA registration is a process you initiate.
Uses of FDA Registration for Compliance
FDA registration serves several purposes: ✔️ Allows the FDA to know who is making what products ✔️ Enables the FDA to contact you in emergencies ✔️ Creates legal permission to sell certain regulated products ✔️ Establishes your compliance with specific regulations For example, all food facilities must register under the Food Safety Modernization Act (FSMA), and dietary supplement manufacturers must register their facilities as well.
Process of Registering with the FDA
The FDA registration process for food products typically involves: Creating an account in the FDA Industry Systems (FIS) Completing the appropriate registration form Designating a US agent (for foreign facilities) Submitting the registration Renewing registrations as required (food facilities must renew every even-numbered year) After registration, the FDA will assign you an FEI if you don’t already have one.
Industries Necessitating FDA Registration
FDA registration is required for: ✔️ Food and beverage manufacturers, processors, and packers ✔️ Dietary supplement producers ✔️ Drug manufacturers ✔️ Medical device companies ✔️ Cosmetics companies (voluntary but recommended) ✔️ Food importers ✔️ Food storage warehouses The importance of FEI for FDA compliance becomes clear once you’re registered, as that identifier will be central to your ongoing regulatory relationship.
Comparing the Three Identifiers
Key Differences Between FEI, DUNS, and FDA Registration
Here’s a simple way to differentiate between these identifiers: ✔️ FEI: FDA-specific facility identifier; assigned to you by the FDA ✔️ DUNS: Global business identifier; you apply for it from Dun & Bradstreet ✔️ FDA Registration: A process you complete with the FDA that may result in receiving an FEI Understanding how to differentiate between FEI and DUNS is essential for properly completing various applications and forms.
Situations When Each Identifier is Required
✔️ FEI is needed when communicating with the FDA about a specific facility ✔️ DUNS is required for government contracts and establishing commercial relationships ✔️ FDA Registration is necessary before legally selling regulated products in the US For example, when importing food products, you’ll need your FDA registration information for prior notice, but customs brokers might ask for your DUNS number for their own records.
Overlapping Requirements and Compliance Needs
Sometimes these identifiers overlap. For instance, when registering food facilities with the FDA, you may be asked for your DUNS number as part of the registration process, even though they will ultimately assign you an FEI.
Practical Implications for Businesses
How to Choose the Right Identifier
When filling out forms or applications: For FDA regulatory submissions, use your FSVP Agent For business transactions and credit applications, use your DUNS For initial product approval, complete FDA registration first The benefits of FSVP compliance for international businesses include streamlined FDA communications and smoother import processes.
Consequences of Non-Compliance
Using the wrong identifier – or none at all – can lead to: ✔️ Delayed product shipments ✔️ Import detentions ✔️ Regulatory enforcement actions ✔️ Rejected applications ✔️ Missed business opportunities For example, if you try to import food without completing FDA registration first, your shipment will likely be detained at the port.
Recommendations for Businesses in Regulated Industries
✔️ Obtain a DUNS number early – the steps to obtain a DUNS number are straightforward, and it’s free for basic registration ✔️ Complete your FDA registration before manufacturing or importing products ✔️ Keep track of your FEI once assigned, as you’ll need it for all FDA communications ✔️ Maintain all registrations and keep them current with any facility changes Conclusion FEI numbers, DUNS numbers, and FDA registrations each play distinct roles in the regulatory ecosystem.
The FEI connects you specifically with FDA regulatory systems. Your DUNS number establishes your global business identity. FDA registration is the process that legally permits you to produce or import regulated products.
For businesses navigating US food, supplement, cosmetic, or medical device regulations, understanding these identifiers is not just about compliance – it’s about ensuring your products move smoothly through the supply chain without costly delays or rejections.
Keeping track of which identifier goes where might seem tedious, but it’s a fundamental part of successful regulatory management and business growth in regulated industries.
