Ship Station License

​​​When you install maritime radio equipment or buy a new ship with maritime radio equipment, you must have a Ship Station License. You apply for this from the Danish Maritime Authority.

When being issued with a Ship Station License, the ship is assigned a call sign and an MMSI number. If the ship has portable VHF equipment with DSC function, a portable ID number will also be assigned.

A Ship Station License is assigned to one ship, and the assigned identification numbers must therefore only be used by that specific ship.

You can read more about changes to and deregistration of the Ship Station License on this page.

Once the Danish Maritime Authority has considered the application and issued the certificate, the owner of the Ship Station License will receive the certificate and a cover letter through e-Boks. These documents will be forwarded by email if you are exempted from e-Boks.

If you are in doubt regarding the application type, then you can read more on the guidance page for Ship Station License or contact us.

Before applying for a new Ship Station License, you must have the following at hand:

  • Your private MitID and credit card
  • Distinctive numbers or letters if the ship is in the register of shipping
  • The ship's field of application according to the ITU ship classification
  • Accounting Authority (AAIC)
  • The radio equipment installed on the ship
  • Contact person ashore in the event of a distress situation

A fee of 175 DKK will be charged for issuing a new call sign. The fee will be settled during the application process.

As the owner of the call sign, it is your responsibility that the information in the Ship Station License is correct.
