    What is an FEI number, and how do you get one?

    An FDA Establishment Identifier (FEI), sometimes called the FDA Establishment Identification number, is a unique identifier the FDA assigns to a facility location. It is required for cosmetic facility registration under MoCRA, drug facility registration, food facility registration and medical device registration.

    Quick answer

    An FEI number (FDA Establishment Identifier) is a unique 7 to 10 digit number that the FDA assigns to a physical facility location. It is required for cosmetic facility registration under MoCRA, food facility registration, drug establishment registration and medical device registration. The FEI is keyed to the address, not the company, and persists across all FDA programmes.

    What is an FEI number?

    The FEI is a unique 7 to 10 digit number assigned by the FDA to a physical facility (an address, not a company). One company operating two facilities will have two FEIs; one facility shared by multiple legal entities has one FEI. The number persists across regulatory programmes, so a single facility's FEI is the same for food, cosmetic, drug and device registration.

    How do you look up an existing FEI number?

    The FDA maintains a public FEI Search portal at fda.gov. You can search by company name, city, country or known FEI. If your facility has ever interacted with the FDA (inspection, registration, drug listing), an FEI almost certainly already exists. Use the existing one rather than requesting a new one.

    How do you request a new FEI number?

    If your facility does not have an FEI, you can request one through the FDA's FEI Search Portal using the "Request an FEI" function. You will need the facility name, full physical address (no PO boxes), country and a US agent for non-US facilities. The FDA typically issues the FEI within a few business days.

    What is the difference between an FEI, a DUNS and a Registration Number?

    A DUNS number is a Dun and Bradstreet business identifier and is not an FDA identifier. A Registration Number is issued when you complete a specific FDA registration (cosmetic facility, food facility, drug establishment) and is keyed to the FEI. The FEI is the underlying constant; the registration number is the proof of a specific filing.

    What this means for your software stack

    Every cosmetics manufacturing facility placing product on the US market needs an FDA Establishment Identifier and a current MoCRA facility registration, kept in step with the product listings tied to it. Mismatches between FEI, facility registration and listing records are a common MoCRA inspection finding.
