A US FDA Registration Number is a critical regulatory requirement for companies planning to manufacture, export, or sell regulated products in the United States. Despite its importance, many businesses misunderstand what this number represents, how it is issued, and what legal value it carries. This confusion often leads to compliance gaps, shipment delays, and regulatory enforcement actions.
This article provides a clear, practical explanation of the US FDA registration number, including its purpose, types, eligibility, verification methods, and the correct way to use it in regulatory and commercial contexts.
Understanding the US FDA Registration System
The U.S. Food and Drug Administration regulates a wide range of products, including drugs, medical devices, food, dietary supplements, and cosmetics. To maintain oversight, the US FDA requires facilities involved in manufacturing, processing, packing, or holding these products to register with the agency.
When a facility completes this process, it is assigned a US FDA registration identifier, commonly referred to as a US FDA registration number. This identifier allows the agency to track inspections, compliance history, and regulatory correspondence.
What Exactly Is a US FDA Registration Number?
A US FDA registration number is not a product license and not an approval certificate. It is a facility-level identification record confirming that a company has fulfilled mandatory registration requirements under applicable US regulations.
Key characteristics of a US FDA registration number include:
- Assigned to a physical facility, not a product
- Required for regulatory compliance, not marketing claims
- Subject to annual renewal for most product categories
- Used internally by the US FDA for inspections and enforcement
Using a US FDA registration number incorrectly can result in serious regulatory consequences.
Different Types of US FDA Registration Numbers
There is no single universal registration number used across all product categories. The US FDA assigns identifiers based on the nature of the regulated activity.
US FDA Drug Establishment Registration
Drug manufacturers, repackers, relabelers, and API manufacturers must complete drug establishment registration. This applies to both US-based and foreign facilities.
US FDA Establishment Identifier (FEI)
The FEI number is an inspection-tracking identifier used by the US FDA. It is frequently requested during inspections, submissions, and regulatory communications.
US FDA Food Facility Registration
Food and beverage manufacturers, processors, and exporters must register their facilities before shipping products to the United States.
US FDA Medical Device Registration and Listing
Medical device manufacturers must register their establishments and list their devices. Registration does not mean device clearance or approval.
Each registration type exists for regulatory oversight rather than product endorsement.
Is a US FDA Registration Number the Same as Approval?
No. This is one of the most misunderstood aspects of US FDA compliance.
- Registration confirms that a facility is listed with the US FDA
- Approval applies only to certain drugs, biologics, and high-risk devices
- Most products legally sold in the US do not require approval but still require registration
Claiming “US FDA approved” based solely on registration is considered misleading and can trigger enforcement action.
Who Needs a US FDA Registration Number?
A US FDA registration number is mandatory for:
- Drug manufacturers and API producers
- Medical device manufacturers and contract facilities
- Food and beverage processing units
- Dietary supplement manufacturers
- Cosmetic manufacturing facilities
- Foreign exporters supplying US markets
Foreign companies must also appoint a US FDA Agent as part of the registration process.
When Is US FDA Registration Required?
Registration must be completed before:
- Exporting regulated products to the US
- Commercial distribution in the US market
- Listing products with US distributors
- Clearing US customs
In most cases, registrations must be renewed annually. Failure to renew leads to automatic deactivation, making the registration number invalid.
How to Get a US FDA Registration Number
The process depends on the product category but follows a structured framework.
Step 1: Product and Activity Assessment
Determine how your product is classified under US FDA regulations.
Step 2: US FDA Agent Appointment
Foreign facilities must designate a US FDA Agent for official communication.
Step 3: Facility Data Preparation
Accurate legal name, address, operational scope, and contact information are required.
Step 4: Online Submission
Registration is submitted through US FDA electronic systems applicable to the product category.
Step 5: Confirmation and Assignment
Once accepted, the US FDA assigns the registration confirmation and related identifiers.
Errors at any stage can delay market entry or result in compliance issues.
How to Search or Verify a US FDA Registration Number
US FDA registration information can be verified through official databases, depending on the product type.
- Drug establishment registrations are searchable through US FDA drug databases
- Medical device establishments appear in registration and listing systems
- Food facility registration status may require importer verification
Not all registration numbers are publicly visible, and absence from public databases does not always indicate non-compliance.
Common Compliance Mistakes
Many companies face US FDA issues due to avoidable mistakes, including:
- Confusing registration with approval
- Using expired or cancelled registration numbers
- Incorrect facility classification
- Missing annual renewal deadlines
- Inaccurate facility or ownership details
- Improper use of registration numbers in marketing
These errors can result in warning letters, import alerts, or shipment detention.
US FDA Registration for Indian Companies
Indian manufacturers exporting drugs, devices, food, or cosmetics to the US are fully subject to US FDA regulations. Inspections of Indian facilities are common, and registration data inconsistencies are frequently cited in inspection observations.
Maintaining accurate and current registration information is essential for uninterrupted exports.
