FDA Establishment Identifier

FDA Establishment Identifier (FEI)

Owners or operators of places of business (also called establishments or facilities) that are involved in the production and distribution of medical devices intended for use in the United States are required to register annually with the FDA. This process is known as establishment registration.

Domestic and foreign establishments that manufacture, repack, or re-label drug products in the United States are required to register with the FDA, and list all of their commercially marketed drug products.

Having an FEI Number and DUNS Number will facilitate the application process and establishment registration.

Section 510 of the Food, Drug, and Cosmetic Act requires that each initial and annual drug establishment registration include a Unique Facility Identifier (UFI).

FDA’s preferred UFI for a drug, medical device or cosmetic establishment as well as food facility, is the DUNS Number, assigned and managed by Dun & Bradstreet Inc.

FDA recommends that at the time of registration, the owner or operator obtain an FEI Number. Firm Establishment Identifier (FEI) should be used for identification of entities within the imports message set.

An FDA Establishment Identification (FEI) number is a unique identifier issued by the FDA to track inspections of regulated establishments or facilities. FEI numbers are also used to track User Fees payments.

Please note that an FEI Number is different from an Employer Identification Number (EIN) also known as a Federal Tax Identification Number used to identify a business entity.
