505 emergency calling

Free direct-dial safety service


505 Emergency Calling is a short code dialling facility that provides direct access to maritime relief. In a time of distress, a seafarer need only dial ’505′ – selected for its similarity to ‘SOS’ – to immediately contact a Maritime Rescue Co-ordination Centre (MRCC).

Please note that 505 Emergency Calling is not GMDSS compliant, and equipment compliant with GMDSS should be used in the first instance by those vessels equipped with it.

In an emergency, calling ’505′ will connect you to one of three MRCCs strategically located across the globe. You will be offered assistance in any type of emergency.

If you require rescue or other action, the MRCC will ensure you receive prompt assistance from those best suited to address your circumstances and location.
