Beginning July 24, 2022, the entity identification code “UNK” will no longer be accepted in the Entity Number field by U.S. Customs and Border Protection (CBP). Consistent with 21 CFR 1.509(a),FSVP importers will be required to ensure that their valid, 9-digit DUNS number is provided in the Entity Number field.

The entity identification code “UNK” was accepted temporarily to allow https://www.ecfr.gov/current/title-21/chapter-I/subchapter-A/part-1/subpart-L/section-1.509 time to obtain a Data Universal Numbering System (DUNS) number. On July 24, 2022, CBP will reject an entry line of a food subject to the FSVP regulation when the FSVP importer’s DUNS number is not provided in the Entity Number field.

If you already have a DUNS number, you do not need to obtain a new DUNS number.
The DUNS number, which is location specific, must correspond to your U.S. location. If you have multiple U.S. locations and multiple DUNS numbers, use the DUNS number that applies to the location at which you maintain your FSVP records.

Requesting a DUNS Number

Request a new DUNS number from Dun & Bradstreet (D&B) through the D&B’s Import Safety Lookup Portal https://importregistration.dnb.com/?utm_medium=email&utm_source=govdelivery You may also use the Portal to look-up a DUNS number or request an update to a current DUNS number.
