A Facilities Information and Resources Management System (FIRMS) Code is a four digit alpha-numeric identifier assigned by U.S. Customs and Border Protection to:

1. Container Freight Stations,

2. Warehouse Deconsolidators,

3. Foreign Trade Zones,

4. Bonded Warehouses,

5. or any other US Customs Service bonded facility.

The FIRMS Code represents the location of certain goods. The FIRMS location must be bonded and on file in Automated Manifest System (AMS). The FIRMS Code is assigned to a location when the bond for that location has been filed with Customs and Border Protection (CBP).[1]

CBP does provide a list of FIRMS Codes. This information is required on all entries. If you are unable to locate your code, please contact the facility where your goods will be located pending Customs clearance to get that facility's FIRMS Code before you file your entry.

FIRMS codes are used when communicating with a US Customs Port of Entry. They're required on import paperwork, inbond transit orders, and other Customs documents.
