Using USMEM on your shipping documents
Carriers print the port of loading and port of discharge on bookings and bills of lading as UN/LOCODEs, so USMEM is what you will normally see against Memphis on carrier paperwork and in schedule and tracking feeds. The first two characters, US, are the ISO 3166-1 country code for United States of America; 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, Memphis also has a CBP Schedule D code, 2006. 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: USMEM on the bill of lading, 2006 on the entry summary. Airlift coordinates entry filing through our licensed broker network.
Memphis carries the airport classifier in UN/LOCODE, but the code list does not supply an IATA code for it. We do not infer one: the last three characters of a UN/LOCODE often match the IATA code but are not required to, and a wrong code on an air waybill is expensive. Take the IATA code from your airline or forwarder.
