What Is 4 in Morse Code?
The Morse code for 4 is ....-, a sequence of 4 dots and 1 dash. In international Morse code (the ITU standard), every digit from 0 to 9 uses exactly five signals — a mix of dots (·) and dashes (−). Number 4 is four dots followed by a single dash — almost all short signals, with one long tone at the end.
When you hear or read “morse code 4”, “morse code for 4”, “4 morse code”, or “number 4 in morse code”, the answer is always the same five-signal pattern: ....-.
Why Number 4 Is Easy to Recognise
Number 4 has four quick dots followed by one long dash — easy to count by ear, since the dot run matches the digit value. It is the mirror of number 6.

To transmit Number 4 (....-), use this sequence:
ITU Timing Rules
- Dot (·) = 1 unit
- Dash (−) = 3 units (3× longer)
- Signal gap = 1 unit
- Letter gap = 3 units
- Word gap = 7 units

How to Remember Number 4 in Morse Code
Four is four dots, then one dash — almost all short signals, ending long.
Think “di-di-di-di-DAH” — four quick blips followed by a single long tone.
Frequently Asked Questions — Number 4 in Morse Code
4 in Morse code is ....-. The number 4 (four) uses 4 dots and 1 dash, the standard ITU pattern for the digit four.
The Morse code for 4 is ....-. Tap the signals in sequence with a one-unit gap between each.
To send number 4: short press, then short press, then short press, then short press, then long press. All Morse digits use exactly 5 signals.
All Morse digits use exactly 5 signals by ITU standard, making them easy to distinguish from letters (1–4 signals) during transmission.
Number 4 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.
