So just to be clear, I can get a MMSI from the FCC and have one number in both the Fixed VHF and my new handheld VHF. Correct?

And your ASI etc. Yes.

A handheld VHF transceiver with DSC and an integral global navigation satellite system (e.g. GPS) not intended for dedicated use on a particular ship (e.g. a diver’s radio) should be assigned a unique 9-digit number in the format 81M2I3D4X5X6X7X8X9. While currently means do not exist within the U.S. to assign such identities, the Coast Guard has been in discussions with the Federal communications Commission and others on implementing them.

In the interim, VHF handhelds used in the United States should use the MMSI assigned to the ship to which the handheld is primarily associated, even if another radio on that ship uses the same MMSI. Non-commercial users of VHF handhelds not primarily associated with any single ship may use an MMSI provided by an organization such as BOAT US, SEA TOW and U.S. Power Squadron (see above). VHF handhelds should not be used ashore absent FCC or NTIA authorization allowing such use.

And you get if through the FCC if you are not a Federal user. The NTIA if you are a Federal User.

[Do not get through BoatUS if you are leaving the US]

Another linked point. You can have more than one so long as you maintain all the information accurately.

When I got Sonas the AIS was already programmed with an FCC MMSI. This would have to be taken out and sent back to the manufacturer to have changed. So I had the previous owners transfer that to me.

I already had one for the radios.

MMSI # is assigned to the vessel not the device.

MMSI Overview

Maritime Mobile Service Identities (MMSIs) are nine digit numbers used by maritime digital selective calling (DSC), automatic identification systems (AIS) and certain other equipment to uniquely identify a ship or a coast radio station. MMSIs are regulated and managed internationally by the International Telecommunications Union in Geneva, Switzerland, just as radio call signs are regulated. The MMSI format and use is documented in Article 19 of the ITU Radio Regulations and ITU-R Recommendation M.585-6, available from the ITU.

From FCC release September 1, 2016..... permitting general handheld use ashore....

27. We agree with commenters that the public interest will be served by allowing the use of
portable VHF radios ashore, so long as it is limited to enhancing the usefulness of marine VHF radios
without negatively affecting maritime communications. Such limited onshore use will promote flexibility
in the use of marine radio equipment in a manner that furthers maritime safety by encouraging more boaters
to a carry a VHF radio. Specifically, as suggested by ACR, we will permit use of portable marine VHF
radios only in areas adjacent to the water, such as docks and beaches.86
In addition, as suggested by
RTCM, and consistent with our requirements for offshore use, onshore communications using such radios
must relate to the operational and business needs of the associated vessel,87 and must be limited to the
minimum practicable transmission time.88
We amend Section 80.115 accordingly.89
We caution
operators that the Commission’s Enforcement Bureau will continue to investigate complaints against
operators who improperly use marine VHF radios, particularly any violation that concerns unauthorized
transmissions on 156.800 MHz (VHF Channel 16).

Attempting to get back to the original point of this thread...

How did your MMSI get cancelled? I did not think that they had an expiration date, or that they had to be renewed. Am I wrong?

I read that he has never had one, and that this will be his first.

Sounds to me like the OP had a number, and somehow it got cancelled. I don't understand how it could have gotten cancelled. Anyone?

Failure to pay renewal fee?

Sorry, I was responding to #21.

I did not think that there was a renewal fee for an MMSI number. I understand that you have to renew a Ships Radio Station license periodically, and that you might have your MMSI issued along with that license. But for many of us a Ships Radio Station is not a requirement, and an MMSI can be issued without a Ships Radio Station. That, specifically, is what BoatUS does. I searched BoatUS's site and found nothing about renewing an MMSI (though you can request that one be cancelled).

So I'm still confused (nothing new!). Do MMSI numbers expire and/or require periodic renewal? I did not think that they did, but I have been wrong before (at least once or twice, I think

).

Thanks for the thread guys. I just got my HX870 in the mail ($200 from gpsstore.com) and will program the same MMSI that I have for the VHF on Kinship.

psneeld · 03-23-2018, 12:41 PM

no expiration of MMSI.... can even request same number as previous owner to new owner if previous postets on here were correct.
