If your vessel is registered under the Polish flag, you’ll need a valid MMSI (Maritime Mobile Service Identity) license for legal marine radio operations, including VHF, AIS, and EPIRB communication systems.
MMSI is a unique 9-digit identifier assigned to your vessel. It enables secure communication with coast guards, other vessels, and rescue coordination centers via marine radio equipment.
Note: G1E, G2E, GOC, and ROC are valid for 5 years. Others are issued for an indefinite period.
