What is an MMSI number?
An MMSI number (Maritime Mobile Service Identity number) is a special number which identifies your vessel. After obtaining an MMSI number from a government-approved issuing agency, you then program it into your marine radio. When you send DSC messages, your MMSI number will be added to the message. This is especially useful if you send an automated distress message. It makes it easier for rescue craft to identify your vessel. All DSC-capable radios must have an MMSI number before the DSC features will work. Cobra Models MR F55 and MR F75 are DSC-capable.
