Numbers · ITU International Morse Code
Morse code for 0 is ----- — 5 signals (0 dots, 5 dashes).
The number 0 in international Morse code is -----. All ten digits use exactly 5 signals, making them easy to identify during transmission.
Number 0 is transmitted as: long press, then long press, then long press, then long press, then long press.
Select the correct Morse code for 0:
To transmit Number 0 (-----), use this sequence:
| Speed | Dot | Dash | Letter gap | Word gap |
|---|---|---|---|---|
| 5 wpm | 240ms | 720ms | 720ms | 1680ms |
| 10 wpm | 120ms | 360ms | 360ms | 840ms |
| 20 wpm | 60ms | 180ms | 180ms | 420ms |
Repeat the pattern aloud: ----- — until it becomes muscle memory.
The Morse code for number 0 is -----. All numbers use exactly 5 signals. Number 0 uses 0 dots and 5 dashes.
To send number 0: long press, then long press, then long press, then long press, then long press. Numbers always use 5 signals total.
All Morse digits use exactly 5 signals by ITU standard, making them easy to distinguish from letters (1-4 signals) during transmission.
Number 0 is -----. Lower digits have more dots at the start; higher digits have more dashes. This systematic pattern makes numbers easier to learn as a sequence.
Number 0 (-----) always uses 5 signals, while letters use 1-4. This makes it easy to tell numbers from letters during transmission.
