What are MMSI and ISMM?

MMSI (Maritime Mobile Service Identity) and ISMM (Identité du Service Mobile Maritime) refer to the same identification system, with ISMM being the French translation of MMSI. This is a unique 9-digit number assigned to each vessel equipped with a maritime communication system. This number uniquely identifies a vessel in maritime communication systems such as AIS and VHF, facilitating tracking and safety at sea. 

These identification numbers follow a standardized international format where the first three digits (Maritime Identification Digits - MID) indicate the vessel's country of registration. For example: 

• 226 indicates France 

• 235 indicates the United Kingdom 

• 338 indicates the United States
