Using 4909 on entry documents
Port code 4909 identifies San Juan, PR 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), which must be on file before ocean cargo loads for the United States.
The first two digits are the customs district: 4909 belongs to district 49, and every port of entry in that district starts with the same two digits.
The code is for customs, not carriers. 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. For San Juan, PR that UN/LOCODE is PRSJU; give the broker 4909 and the carrier the UN/LOCODE.
CBP adds and retires codes as ports of entry open, merge or close, so confirm 4909 against the current CBP publication before filing. Airlift USA does not hold a U.S. customs broker license; entries on cargo we move are filed through our licensed broker network.
