Presently, the codes used are either the MMSI No. or the MID + Radio call
sign or serialized protocols (one per vessel).
The IMO number or national

Access to information concerning the
contact persons (names, addresses, telephone and telefax numbers) as well as
alternative 24-hour emergency telephone numbers, is restricted to
administrations and by extension to Rescue Coordination Centres.
Note:
Administrations will be provided, on receipt of a formal request addressed
to the Director of the Radiocommunication Bureau, with a unique account number,
consisting of a username and password. The account numbers will allow users
access to the information mentioned in the above paragraph. It will be the
responsibility of administrations to provide their account number to the Rescue
Coordination Centres under their jurisdiction, for whom this information may be
necessary for effective and coordinated search and rescue activities in the
current Global Maritime Distress System (GMDSS ) regime.
