Obtain MMSI (Maritime Mobile Service Identity) number

Before commencing installation ensure you have obtained a MMSI number for your vessel.
A MMSI is a 9 digit number which is sent over a radio frequency channel in order to identify the
originating vessel/station. If your vessel already has a MMSI number (used for a VHF DSC radio) then
the same MMSI number must be used to program your product.
Note:
If a MMSI number is not entered, the DSC functionality of your radio will be disabled.
In the United States of America, the MMSI and Static Data must be entered only by a Raymarine®
dealer or other appropriately qualified installer of marine communications equipment on board
vessels.
The user is NOT authorized to do this.
In some areas, a radio operator licence is required before a MMSI number will be issued. You can
request a MMSI number from same agency that issues radio or Ship Radio licences in your area.
In Europe and other parts of the world outside of the United States of America, the MMSI and Static
data can be set up by the user.
For further details, refer to the relevant Telecommunications Regulatory Body for your area.
Refer to Appendix A MMSI Regulatory bodies and application submissions
for a list of contacts for obtaining MMSI numbers for some areas.
