Morse Code for 0
The digit 0 is −−−−−. 0 is five dahs — longer than the letter O (three dahs), so operators never treat them as the same signal.

Letter-by-letter Morse for 0
Digits use five Morse elements. 0 is −−−−− (dahdahdahdahdah).

About Morse for the digit 0
0 sits next to 9 (−−−−·) and the letter O (−−−) — O is only three dahs, not five.
Sending 0 at 18 WPM takes about 1.3 seconds (dahdahdahdahdah).

How to tap 0
- The pattern is −−−−− (dahdahdahdahdah). A dit is a short tap or flash; a dah is about three times longer.
- 0 is a single character, so you only need the tiny gap between its own dits and dahs.
- At 18 WPM this takes about 1.3 seconds. Slow down to 12 WPM if you are still learning the rhythm.
- Press Play to hear 0, or turn on the lamp and match the flashes.
Easy to mix up
0 is easy to mix with O (−−−). Learn both rhythms so they stay distinct.
Morse Code for 0 — FAQ
What is the Morse code for 0?
The Morse code for “0” is −−−−−. That uses 0.
How do you tap or flash 0 in Morse?
Match −−−−−: short for each dit, about three times as long for each dah. Press Play on this page, then copy the same timing with a tap, whistle, or flashlight.
How long does 0 take to send?
At 18 WPM, “0” takes about 1.3 seconds. At 12 WPM the same −−−−− pattern is slower but the dit/dah ratios stay identical.
