Using 2820 on entry documents

Port code 2820 identifies Martinez, ca as the port of entry on CBP Form 7501, the entry summary a broker files for every formal entry. The same four digits identify the port in ACE entry filings, in AMS manifest data and in the Importer Security Filing (ISF) that must be on file before ocean cargo loads for the United States. The code belongs to the customs district whose two-digit number it begins with — San Francisco, CA (district 28) — and every port of entry in that district shares the same first two digits.

The code is a customs identifier, not a carrier one. Carriers, forwarders and NVOCCs book and manifest against the UN/LOCODE for the place, and the bill of lading shows that five-character code, not the Schedule D code. Many Schedule D ports of entry — airports, land border crossings, user-fee airports and inland ports — have no UN/LOCODE seaport entry at all, and this site does not hold a UN/LOCODE page for Martinez, ca; the UN/LOCODE finder searches the full code list.

Codes are added and retired as ports of entry open, merge or close, so confirm 2820 against the current CBP publication before filing. Airlift USA does not hold a U.S. customs broker licence; entries on cargo we move are filed through our licensed broker network.
