Having an MMSI (Maritime Mobile Service Identity) programmed into your AIS (Automatic Identification System) or marine radio is essential for:

1. Safety and Identification: The MMSI serves as a unique identifier for your vessel, allowing other vessels and maritime authorities to identify your boat quickly. In emergencies, the MMSI helps rescue services locate and assist you quickly.
2. AIS Communication: AIS transponders use the MMSI to exchange crucial information with other vessels and shore stations. This communication enhances situational awareness, especially in busy waterways or areas with high maritime traffic.

Our guest expert for this episode of Boating Insights is Linda Berryman, whose role at AMSA involves providing specialist advice on distress alerting, communication and safety systems.

You can apply for an Australian MMSI number by completing an MMSI application online at www.amsa.gov.au/mmsi
