Morse Code Numbers
Each digit from 0 to 9 has its own five-signal Morse code pattern, distinct from the letter alphabet. This chart shows every number’s dot-dash sequence, and explains the simple logic that makes the whole set easy to remember at once.

The Pattern Behind Morse Code Numbers
Five Signals, Every Time
Unlike letters, every Morse code number uses exactly five signals, which makes the whole set predictable once you see the pattern. For 1 through 5, the number of dots matches the digit itself, followed by enough dashes to reach five signals total — 1 is one dot and four dashes, 5 is five dots and no dashes. For 6 through 9, it flips: the digit tells you how many dashes come first, followed by dots to fill out the remaining signals — 6 is one dash and four dots, 9 is four dashes and one dot. 0 is the outlier, five dashes with no dots at all.
then dashes fill to five
then dots fill to five
Numbers vs. Letters: Why They’re Built Differently
Morse code letters vary in length — from one signal (E, T) to four (like Q or Z) — because the system rewards common letters with shorter codes. Numbers don’t follow that logic at all: every digit, 0 through 9, always uses exactly five signals, no exceptions. That fixed length is deliberate — it makes numbers instantly distinguishable from letters and from each other, since a listener always knows exactly how many signals to expect.
Commonly Confused Numbers
Because every number uses five signals, the easiest ones to mix up are those that differ by only one signal, or where it’s easy to lose count partway through:
- 4 vs. 5. 4 is four dots then one dash (····–); 5 is five dots (·····). Losing the very last signal turns a 5 into a 4.
- 6 vs. 7. 6 is one dash then four dots (–····); 7 is two dashes then three dots (––···). Miscounting the dashes by one shifts the whole digit.
- 9 vs. 0. 9 is four dashes then one dot (––––·); 0 is five dashes and nothing else (–––––). This is the easiest number mistake to make — it comes down to hearing, or missing, one final dot.
A Faster Way to Read 6 Through 9
Since 6 through 9 are dashes-then-dots, it’s often faster to count the dots at the end instead of the dashes at the front: take the number of trailing dots and subtract it from ten. A dash followed by four dots has four trailing dots, so it’s 10 − 4 = 6. Four dashes followed by one dot has one trailing dot, so it’s 10 − 1 = 9. (0 is the only exception — five dashes and no dots at all, as noted above.)
Numbers in Morse Code: Worked Examples
Numbers rarely appear alone — most real Morse messages mix them with letters. Here’s the year 2026, spelled out in full: 2 (··–––), 0 (–––––), 2 (··–––), 6 (–····) — four separate five-signal characters, each followed by a normal letter-to-letter pause. Amateur radio operators use this constantly in signal reports: a classic “perfect copy” report, 599, is just three numbers back to back — 5 (·····), 9 (––––·), 9 (––––·).
Common Mistakes With Morse Code Numbers
- Expecting numbers to be short, like some letters. E and T are a single signal each, but no number ever is — every digit is always five signals.
- Miscounting mid-run. All-dot or all-dash stretches (like 4 or 0) are the easiest to lose count in, since there’s no rhythm change to help you — deliberate counting matters more here than anywhere else on the chart.
- Confusing the number 0 with the letter O. They’re not actually close in length — see the FAQ below for the full comparison.
Where Morse Code Numbers Are Still Used
Numbers show up anywhere Morse code itself is still active. Amateur radio operators exchange signal reports (like the 599 example above) in nearly every contact. Aviation navigation beacons identify themselves with short Morse idents that can include numbers alongside letters. And in distress or emergency contexts, precise numeric information — coordinates, frequencies, times — has to be sent digit by digit, since numbers have no shorthand the way common letters do.
Frequently Asked Questions
Why do all Morse code numbers use five signals?
It keeps the numeral set completely predictable and easy to tell apart from letters, which range from one to four signals. Once you know a character is five signals long, you know it’s a number before you’ve even finished decoding which one.
How is the number 0 different from the letter O?
They’re not close: 0 is five dashes (–––––), while the letter O is three dashes (–––). If you’re counting signals as you listen, they’re impossible to confuse — the mix-up only happens when someone stops counting and guesses.
Can numbers and letters be mixed in the same message?
Yes, normally. Numbers and letters use the same timing and the same spacing between characters, so a message like “ROOM 237” is simply sent as its letters and digits back to back, each separated by a normal letter gap.
Is there a shorthand for numbers, like there is for common letters?
No. Unlike letters, where common ones like E and T get shorter codes, every Morse code number is deliberately the same length. Some historical telegraph operators used informal shortcuts called “cut numbers” to save time, but these were never standardized and aren’t used in Morse code today. International vs. American Morse Code covers other ways the older systems diverged.
