ITU List V, the List of Ship Stations and Maritime Mobile Service Identity Assignments, 2026 Edition, is the International Telecommunication Union's yearly list of ship stations and their MMSI numbers. Under the ITU Radio Regulations (No. 20.8 and Appendix 16), List V must be provided to every ship station that is required to carry a GMDSS installation.

Edition at a glance

What's inside

• Ship stations listed with their names, call signs and MMSI numbers
• The radio installations and services each ship station uses
• Accounting authority identification codes (AAIC) for radiocommunication charges
• Information supporting GMDSS distress and safety communications

How it's used

Radio operators, coast stations and rescue coordination centres use List V to identify a ship from its MMSI or call sign, and to find how to reach it. That matters most during distress, urgency and safety traffic, when a station has to be identified quickly and correctly.

Who needs it

Ships fitted with GMDSS, coast stations, maritime administrations and ship managers who keep radio documentation up to date.
