MMSI allows a VHF radio to act like a phone. The 9-digit MMSI 

number acts like a phone number when used in a position report and 

as a unique identifier to the Coast Guard when used in an emergency 

distress call. To obtain a MMSI number, users must register their 

VHF radio with the FCC (Form 605). Garmin does not supply this 

number!

Non-commercial users, such as recreational users, who remain 

in United States waters and only carry VHF, EPIRB (Emergency 

Position Indicating Radio Beacons), and Radar are not required to 

have a FCC ship station license. The FCC and Coast Guard have 

authorized some second and third-party vendors to assign MMSI 

numbers. This service is limited to registering recreational vessels 

only. To receive information on how to obtain a recreational MMSI 

number, contact 

Commercial users, or those who travel outside the United States or 

Canada, must apply for a ship station license or an amendment to a 

ship station license. To find out if you require a Ship Station license, 

requires licensing by the FCC, you can obtain a MMSI during the 

application/licensing process when you file FCC Forms 159 and 

605.

Federal users can obtain MMSI assignments from their agency 

radio spectrum management office. These procedures are currently 

under review by the National Telecommunications and Information 

Administration (NTIA).

Users can obtain an MMSI assignment from their telecommunications 

authority or ship registry, often by obtaining or amending their ship 

station license.

Industry Canada is responsible for assigning MMSI numbers to 

commercial and recreational vessels. Information is available at the
