To make a “call” on a phone, you first need a phone number to dial. The9-digit MMSI number acts like a phone number when used in a Position Reportand as a unique identifier to the Coast Guard when used in an emergency distresscall. To obtain a Maritime Mobile Service Identity (MMSI) number, users mustregister their VHF radio with the FCC (Form 605). Garmin does not supply thisnumber!How Are MMSI Assignments Obtained?Non-commercial users (recreational users who remain in domestic waters andonly carry VHF, EPIRB (Emergency Position Indicating Radio Beacons, andRadar)) are not required to have a FCC ship station license. The FCC and CoastGuard have authorized some second and third-party vendors to assign MMSInumbers. This service is limited to registering recreational vessels only.
