Carriers print the port of loading and port of discharge on bookings and bills of lading as UN/LOCODEs, so PRSJU is what you will normally see against San Juan on carrier paperwork and in schedule and tracking feeds. The first two characters, PR, are the ISO 3166-1 country code for Puerto Rico; the remaining three identify the place within it.
A UN/LOCODE names a place, not a berth. Where a port city runs several container terminals, UNECE often assigns the terminals their own codes alongside the city code — which is why a booking can legitimately show a code you did not expect. Take the code from the carrier booking rather than picking the one that reads most like the port name.
For a US import, San Juan also has a CBP Schedule D code, 4909. That four-digit number identifies the customs port of entry and is what goes in the port field of CBP Form 7501. The two systems are unrelated and are not interchangeable: PRSJU on the bill of lading, 4909 on the entry summary. Airlift coordinates entry filing through our licensed broker network.
