Maritime Mobile Service Identity

A Maritime Mobile Service Identity (MMSI) is a unique nine-digit number assigned to ships, boats, and maritime communication devices. It functions like a digital fingerprint, allowing vessels to identify themselves during radio communication, especially in emergencies or navigation. The MMSI helps coast guards, rescue teams, and other vessels quickly recognize and exchange information with a specific vessel. It is vital for safety, efficient communication, and tracking at sea, much like a unique identification number used in other systems to ensure accurate and secure interactions.
