Sao Tome And Principe Port Codes
UN/LOCODE records use the country prefix ST followed by a three-character location identifier. Code status, spelling and operational use should be checked against the latest directory and carrier booking system before shipment release.
City-Level and Terminal-Level Records
A city-level location and an individual terminal may appear as separate records. A port name in the directory does not by itself confirm berth availability, vessel acceptance or current carrier service.
How to Verify a Port Code
Compare the booking instruction with the current UNECE UN/LOCODE reference and the Ecer Freight Port Codes directory before requesting a quote or issuing shipping documents.
