CBP Fax Number — Trade, Passenger, and Records Submissions

U.S. Customs and Border Protection covers trade enforcement, passenger processing, and many field operations through separate ports of entry and program offices, so faxes are directed by program rather than to one national number. A trade or entry-related document goes to the office named in that program's instructions, while records requests and passenger redress inquiries each have their own process. The reliable approach is to open the official CBP page or the specific form's instructions for your matter, which state the accepted contact channels. Because CBP routes many submissions through online systems such as the trade portals and DHS TRIP, confirm whether fax is accepted for your request before sending.

U.S. Customs and Border Protection (CBP) Fax Number

Confirm the correct fax destination on the specific CBP program's official page or form instructions — ports of entry, trade programs, and FOIA route separately

Hours: CBP program offices generally operate Monday through Friday during federal business hours, while ports of entry maintain their own operational schedules that can extend beyond standard hours. Confirm hours on the relevant program or port page.

What You Can Fax to U.S. Customs and Border Protection (CBP)

  • Trade and entry documentation a CBP port or center has requested by fax
  • Broker and importer correspondence tied to a specific entry
  • Supporting documents for a passenger redress or inquiry case
  • FOIA requests and related records materials
  • Program forms listed on an official CBP page
Tip: Verify the fax destination on the specific CBP program page or form instructions before sending, since a general agency number will not reach the port or center handling your matter. Do not assume fax is required — CBP directs much of its trade and traveler correspondence through online portals — so confirm the accepted channel first. Keep the transmission receipt and reference any entry, case, or inquiry number on the cover sheet so your document can be matched to the correct file.

Faxing to U.S. Customs and Border Protection (CBP) — FAQ

No. Trade matters, passenger processing, and records requests are handled by different CBP offices and ports, each with its own contact process. Identify the specific program or port involved and use the contact information on its official page rather than a single number.

Trade and entry documentation is generally submitted through CBP's electronic trade systems or as directed by the port or center handling the entry. Confirm the accepted channel in that program's instructions, and only fax when the office specifically requests it, keeping proof of transmission.

Traveler concerns such as inspection or watchlist redress are typically handled through the DHS Traveler Redress Inquiry Program (DHS TRIP) and CBP's published inquiry channels. Follow the process on the official page for your issue and confirm whether fax is an accepted method before sending.

CBP's FOIA office publishes its accepted submission methods, which usually include an online portal, email, and mail. Check the current CBP FOIA page to confirm whether fax is accepted and to obtain the correct destination before submitting a request.
