The US FDA FEI Number is a core regulatory identifier used by the United States Food and Drug Administration to recognize, monitor, and regulate establishments involved in FDA-regulated activities. For companies operating in drugs and cosmetics, correct handling of the FDA Establishment Identifier (FEI) is essential to maintain compliance, avoid registration rejection, and ensure smooth annual renewals.
XPRO America functions as a US FDA Consultancy, assisting establishments worldwide with FEI identification, verification, and FDA establishment registration support.
What Is the FDA Establishment Identifier (FEI)?
An FEI number (Firm Establishment Identifier) is a unique, FDA-assigned numeric code linked to a physical establishment. It is not a product approval number, license, or certification. Instead, it serves as the FDA’s permanent reference for a facility throughout its regulatory lifecycle.
Key characteristics include:
- Issued exclusively by the US FDA
- Assigned to a specific physical location
- Permanent and non-transferable
- Used across inspections, registrations, and compliance records
Once an FEI number is assigned, it remains associated with that establishment even if the company name or ownership changes.
What Is the FEI Number for the FDA?
From the FDA’s regulatory system perspective, the FEI number is the central facility identifier. It connects multiple regulatory elements, such as:
- Establishment registration and renewal records
- Inspection history and outcomes
- Compliance status and enforcement actions
- Internal FDA tracking and evaluation systems
Because of this linkage, accurate FEI usage is critical during every registration and renewal cycle.
Who Needs an FEI Number?
An FEI number is required for establishments that must register with the US FDA. This typically includes:
- Drug manufacturing and processing facilities
- Active pharmaceutical ingredient (API) manufacturers
- Drug repackagers and relabelers
- Cosmetic manufacturing establishments
- Contract manufacturing and testing organizations
If your operations fall under FDA Drug Establishment Registration, an FEI number is mandatory for initial registration and for annual renewals.
Where Can I Find My FDA FEI Number?
A frequent compliance question is, “Where can I find my FDA FEI number?” FEI numbers are not always visible in public databases, but they are usually available through:
- FDA inspection correspondence
- Establishment Inspection Reports (EIR)
- FDA Form 483, if issued
- Previous FDA registration or renewal filings
- Official FDA regulatory emails
If records are missing or inconsistent, professional FDA Establishment Identifier (FEI) Registration Assistance helps confirm and validate the correct FEI before submission.
How to Search FEI Number
Many firms ask, “How to search FEI number?” FEI numbers are not publicly searchable due to confidentiality and data protection requirements.
However, FEI identification and verification can be completed through:
- Historical FDA registration documentation
- Inspection records and compliance history
- Firm/Supplier Evaluation Resources
- Internal FDA system verification during registration or renewal
XPRO America supports establishments in accurately validating FEI details to reduce the risk of submission errors or regulatory delays.
What Is a US FDA Number?
The term US FDA number is often used broadly and may refer to different identifiers, including:
- FEI number (establishment identifier)
- Establishment registration number
- Product listing reference
Among these, the FEI number uniquely identifies the facility, not the product. Confusing these identifiers is a common cause of registration and renewal issues.
FDA Drug Establishment Registration & FEI Number
For drug-related establishments, the FEI number plays a central role during:
- Initial FDA Drug Establishment Registration
- Annual US FDA Drug Establishment Registration Renewal
- Drug product listing submissions
- Inspection readiness and post-inspection responses
Any mismatch between FEI records and registration data can result in delayed renewals, rejection notices, or compliance queries.
How to Check US FDA Registration Status
Although FEI numbers are not openly displayed, they are used internally by the FDA to confirm:
- Establishment registration validity
- Inspection history
- Regulatory compliance status
Ensuring FEI accuracy before filing helps maintain alignment with FDA records and prevents unnecessary corrections.
