Is the FEI the same as a registration number or DUNS number?
No. An FEI is assigned by the FDA specifically for inspection and regulatory tracking. A DUNS number is issued by Dun & Bradstreet for business identification and is often required during drug listing or GDUFA submissions. They serve different regulatory purposes.

How long does it take to receive an FEI?

Does the FEI need to be renewed?
No, an FEI number does not expire. However, it’s important to keep your facility’s information up to date with the FDA. Changes in facility address, ownership, or business activity may require updates to your FEI profile.

Is there a government fee to obtain an FEI?
No. The FDA does not charge any fee for assigning an FEI. However, if you’re using a third-party consultant (like Cliniexperts), a service fee may apply for handling the request and ensuring compliance.
