What Is 3 in Morse Code?
The Morse code for 3 is ...--, a sequence of 3 dots and 2 dashes. In international Morse code (the ITU standard), every digit from 0 to 9 uses exactly five signals — a mix of dots (·) and dashes (−). Number 3 is three dots followed by two dashes — exactly halfway through the rising sequence.
When you hear or read “morse code 3”, “morse code for 3”, “3 morse code”, or “number 3 in morse code”, the answer is always the same five-signal pattern: ...--.
Why Number 3 Is Easy to Recognise
Number 3 has a balanced rhythm: three quick dots and two long dashes. It sits exactly in the middle of the digit sequence, making it a natural anchor when learning the numbers from 0 to 9.

How to Tap Number 3 in Morse Code
To transmit Number 3 (...--), 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
Timing Reference Table
| Speed | Dot | Dash | Letter gap | Word gap |
|---|---|---|---|---|
| 5 wpm | 240ms | 720ms | 720ms | 1680ms |
| 10 wpm | 120ms | 360ms | 360ms | 840ms |
| 17 wpm (this page) | 70ms | 210ms | 210ms | 490ms |
| 20 wpm | 60ms | 180ms | 180ms | 420ms |
How to Remember Number 3 in Morse Code
Three is three dots, then two dashes — the digit and the dot count match.
Think “di-di-di-DAH-DAH” — three quick blips, then two long tones.
Frequently Asked Questions — Number 3 in Morse Code
3 in Morse code is ...--. The number 3 (three) uses 3 dots and 2 dashes, the standard ITU pattern for the digit three.
The Morse code for 3 is ...--. Tap the signals in sequence with a one-unit gap between each.
To send number 3: short press, then short press, then short press, then long 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 3 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.
