What Is the At Sign in Morse Code?
The Morse code for the at sign (@) is .--.-. — a sequence of 6 signals: dot, dash, dash, dot, dash, dot. The at sign (@) was added to ITU Morse code in 2004 specifically to support email addresses. It’s six signals: dot dash dash dot dash dot — essentially A + C combined.
When you search for “at sign in morse code”, “morse code for at sign”, “@ in morse code”, or “morse code @”, the answer is the same ITU-standard pattern: .--.-.. Other common names for this character include at symbol, commercial at.
When to Use the At Sign
Sending email addresses by Morse code (the only reason it was standardised). In high-speed CW conversation, operators often skip non-essential punctuation — but for clarity, accuracy and written transcripts, the at sign stays as .--.-..

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 |

How to Remember the At Sign in Morse Code
Dot-dash-dash-dot-dash-dot — like the letters A and C run together (AC). The newest official Morse character, added in 2004.
Frequently Asked Questions — At Sign in Morse Code
The at sign (@) in Morse code is .--.-. (3 dots, 3 dashes). It’s the standard ITU code used worldwide.
The Morse code for the at sign is .--.-.. Tap the sequence as: dot, dash, dash, dot, dash, dot, with a one-unit gap between each signal.
To send the at sign: short tap, then long press, then long press, then short tap, then long press, then short tap. Keep one unit of silence between each signal and three units between this character and the next.
The at sign uses 6 signals total: 3 dots and 3 dashes. Most punctuation marks in ITU Morse use 5 or 6 signals.
Sending email addresses by Morse code (the only reason it was standardised). Punctuation is optional in casual CW, but standard for formal messages and written transcripts.
Yes — .--.-. is defined by the ITU (International Telecommunication Union) Recommendation M.1677 and is used worldwide for the at sign.
