Tonga Port Codes and UN/LOCODEs

Tonga port codes use the country prefix TO. Always verify the exact code, facility, cargo acceptance and current carrier instructions before preparing shipping documents.

TO prefix and three-character location code

A Tonga UN/LOCODE begins with TO, followed by a three-character location identifier. Examples in the Ecer Freight sample include TONUK for Nukualofa and TONEI for Neiafu.

City-level and terminal-level entries

A city-level code and a terminal-level or facility entry may appear separately in logistics systems. The two Nuku'alofa entries TONUK and TOTBU should therefore be checked against the bill of lading, booking confirmation and carrier routing instructions.

How to verify a Tonga port code

Compare the requested location with the UNECE UN/LOCODE reference and then review the available Ecer Freight port directory. Confirm the operational facility with the carrier or local agent before cargo dispatch.
