Already Have Non-BoatUS MMSI?

If you have an expired ship station license and it included an MMSI number assigned by the FCC
You obtained an MMSI number through Maritel, who is no longer providing the service, you may input your existing MMSI number below to re-register the number through BoatUS.

(Please note: The number provided must meet the particular criteria provided by the FCC & Maritel in order to be entered into this form. If you do not have a valid MMSI number, you will need to obtain a new MMSI by returning to the previous page and clicking on "Free MMSI number" at the top of the page.)
