The importance of an MMSI number

An MMSI number is a unique identifier assigned to a boat. Only one number is assigned for all applicable electronics on the vessel, such as an AIS transponder, DSC Radio, and EPIRB.

MMSI registration includes contact information to be used in case of an emergency.
All vessels operating on the high seas require a Maritime Mobile Service Identity (MMSI) number to participate in the Global Maritime Distress & Safety System (GMDSS). In addition to GMDSS participation the MMSI number also serves as a unique identifier of the vessel for all communications.
