What Is 7 in Morse Code?
The Morse code for 7 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 7 is two dashes followed by three dots — the mirror of number 3.
When you hear or read “morse code 7”, “morse code for 7”, “7 morse code”, or “number 7 in morse code”, the answer is always the same five-signal pattern: --....
Why Number 7 Is Easy to Recognise
Number 7 begins with two long tones, then three quick dots. The two-dash opening makes it easy to separate from numbers that start with a single dash.

How to Tap Number 7 in Morse Code
To transmit Number 7 (--...), 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 7 in Morse Code
Seven is two dashes, then three dots — the mirror of 3.
Think “DAH-DAH-di-di-dit” — two long tones followed by three quick blips.
Frequently Asked Questions — Number 7 in Morse Code
7 in Morse code is --.... The number 7 (seven) uses 3 dots and 2 dashes, the standard ITU pattern for the digit seven.
The Morse code for 7 is --.... Tap the signals in sequence with a one-unit gap between each.
To send number 7: long press, then long press, then short press, then short press, then short 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 7 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.
