The International Telecommunication Union (ITU) adopts international regulations and treaties governing all terrestrial and space uses of the radio frequency spectrum. Within these international regulations, individual countries may adopt their own national legislation. The intent is to provide the maritime mobile radio communications user with a group of standard frequencies that are known to all mariners and can be used worldwide.
The following VHF marine frequencies have been set aside by the ITU for the purposes stated. These frequencies are internationally accepted by most nations and will be found on all VHF Marine Radios regardless of where or by whom they are manufactured.
On the following pages, we have listed marine VHF frequency usage tables for a few countries from around the world. While our list is small, we hope that we can build on these tables going forward. If you have information concerning VHF frequency allocation of countries that we have not listed please send it on to us at and we will get it published.
