A VHF call sign is a unique identifier for your vessel and plays an essential role in your safety at sea.
Your call sign helps rescue services identify exactly who they are looking for and should always be used when making Trip Reports, Mayday calls, or other urgent transmissions. Display your call sign clearly near your radio to avoid any delay in providing this critical information.
If you're unsure of your current call sign, contact Coastguard Boating Education. They can assist with updating an existing call sign or issuing a new one.
