International Morse Code

International Morse code is the standard used around the world today. It is defined by the International Telecommunication Union (ITU) and covers the Latin letters, the digits 0 to 9, and a set of punctuation and procedural signals. Our translator uses this standard.

International vs American Morse Code

The original American Morse code, used on early telegraph lines, had some letters with internal gaps and different timing. It was awkward to send over radio. International Morse code, sometimes called continental code, simplified those patterns into the clean dot and dash system in use now. When people say Morse code today, they almost always mean the international version.
