Is Morse Code Still Used Today?

Yes, Morse code is still actively used today, though not the way it was a century ago. It stopped being the mandatory international maritime distress signal in 1999, replaced by the satellite-based GMDSS system, but it survives in several genuinely active, present-day roles rather than existing purely as history.

Amateur Radio, by Choice

Amateur operators keep sending it on the air constantly under its radio name, CW, and nothing has forced them to since 2007, when the FCC dropped Morse from the U.S. licensing exams. The reason it stuck around anyway is practical, not sentimental: a CW signal squeezes into so little bandwidth that it survives conditions — weak batteries, long distances, heavy static — where a spoken voice transmission would simply disappear into the noise floor.

Aviation Navigation Beacons

Many VOR and NDB navigation beacons still broadcast their station identifiers in Morse code, and pilots are trained to listen for that identifier to confirm they've tuned the correct station — a small but genuinely functional piece of Morse code embedded in modern flight operations, still relied on rather than kept as a formality.

Emergency and Backup Signaling

Outdoor educators, search-and-rescue guidance and survival training still teach a basic SOS pattern, since it works with almost no equipment — a flashlight, a whistle, even three marks scratched in the sand — and remains internationally recognized even outside its old formal maritime role.

Puzzles, Hobbies and New Technology

Beyond its practical uses, plenty of puzzle hunts, mystery geocaches and amateur cipher communities lean on it precisely because so many people can half-recognize a dot-dash rhythm without having to look anything up. It's also found a genuinely new job in accessibility technology: apps exist today that let deafblind users tap out and receive entire conversations as Morse-coded vibrations on a phone screen.
