SOS in Morse code is written as ··· --- ··· (three dots, three dashes, three dots).
SOS is the most recognized distress signal in the world. Adopted internationally in 1906, it was chosen for its simplicity in Morse code — three dots, three dashes, three dots — making it easy to transmit and recognize even under extreme conditions.
Why SOS Became the Universal Distress Signal
In Morse code, SOS is sent as one continuous signal (a prosign), not as separate letters — this makes it faster and unmistakable. Contrary to popular belief, SOS does not stand for specific words like “Save Our Souls.” Its strength comes from clear timing and symmetrical rhythm, making it effective even in extreme conditions.
