Where are MMSI numbers obtained from?

MMSI (Maritime Mobile Service Identity) numbers are essential for identifying ships and are typically obtained from an authority responsible for maritime communications in a given country. In Canada, for example, Spectrum Canada is the agency that issues MMSI numbers, aligning with the country's regulatory framework for maritime services.

Spectrum Canada oversees the allocation of these numbers to ensure they are uniquely assigned and that maritime communication systems operate smoothly. This process helps enhance safety and coordination among vessels and maritime authorities. Other entities, such as the Federal Communications Commission, may be responsible for MMSI in the United States, but for Canada, Spectrum Canada is the correct source.

The International Maritime Organization primarily develops the regulatory framework for maritime safety and operating standards internationally, but it does not issue MMSI numbers directly. Coast Guard Radio might provide support and communicate with vessels, but it is not the issuing authority for MMSI numbers.
