Overview

An MMSI (Maritime Mobile Service Identity) number uniquely identifies a vessel's radio and AIS equipment for digital selective calling, distress alerting, and vessel tracking - it is issued alongside your TDRA radio license and programmed into the vessel's equipment.

We handle the MMSI application as part of your radio licensing, and confirm the number is correctly programmed into your VHF-DSC and AIS equipment once issued.

Benefits

Coordinated together with your TDRA radio license application.

Confirmation that the MMSI is correctly programmed into onboard equipment.

Support if a vessel's MMSI needs updating after a change of ownership or flag.

Clear explanation of what MMSI is used for, for first-time owners.

Frequently asked questions

Does my MMSI number change if I sell the vessel?+

It can require updating depending on the transfer, flag, and licensing route. We review the record before advising.

What is the difference between an MMSI and a call sign?+

An MMSI is used for digital radio and AIS identification, while a call sign is a radio identity used in voice communication and licensing records.

Can I get an MMSI without a full radio license?+

In most cases the MMSI is coordinated with radio licensing. We confirm the right route once we review the equipment and vessel registration.
