U.S. Customs and Border Protection maintains two official port code systems. Schedule D assigns numeric codes to domestic ports of entry — the 522 locations where goods may be formally entered for import into the United States. Each port belongs to a customs district and may have dozens of FIRMS facilities attached.
Schedule K covers foreign ports of lading and unlading — the 3,769 international locations from which goods originate or transit before arriving in the US. These codes appear on entry documents, bills of lading, and automated broker interface (ABI) transmissions.
Port codes matter because they determine which CBP Center of Excellence and Expertise (CEE) processes your entry, which FIRMS facilities you can use, and in some cases, which rulings and regulations apply. Knowing the correct port code prevents delays, penalties, and misdirected cargo.
Monitor vessel movements, port congestion, and FIRMS facility status across every US customs district. Integrate port data into your logistics workflows.
