MMSI Registration Information

What is an MMSI Number and Why Do I Have to Register?

By law, in order to use DSC features, fixed mount radios must be assigned an MMSI number and you must program that number into your radio.

There are two kinds of MMSI numbers:

Individual numbers for use by single boats and group numbers for use by fleets, boating organizations, event coordinators, etc.

You can get more information on MMSI numbers at these resources:

• The dealer where you purchased the radio.
• Recreational boaters can obtain an MMSI number from the Boat Owner’s Association of the U.S. (http://www.boatus.com/mmsi/ or call 800-563-1536) or Sea Tow Services International (https://www.seatow.com)
• Commercial boaters need a ship station license to get an MMSI number. For more information, visit the Federal Communications Commission (FCC) website at http://wireless.fcc.gov/marine/fctsht14.html

MMSI number not entering?

Due to FCC regulations, all DSC marine radios have a maximum of 1 or 2 attempts to enter the MMSI number (Depends on model) then the radio locks up and prohibits any further attempts.
