Get a Call Sign

A call sign is a unique identifier for your vessel.  In New Zealand call signs begin with the letters ZM followed by another letter and four numbers.  Call signs can be obtained by visiting and following the call signs tab. 

Maritime VHF radio callsigns are issued for vessels operating within New Zealand Waters only. New Zealand registered vessels heading offshore may require an individual ships radio license rather than the standard general user radio license.

Get an MMSI number

MMSI stands for Maritime Mobile Service Identifier.  An MMSI is issued by Radio Spectrum Management and is permanently attached to a callsign. They must not be separated. 

An MMSI, once entered into a radio transmitter or AIS equipment, is very difficult and often costly to remove, therefore it is highly recommended that the callsign and MMSI remain with the vessel.
