Morse Code Numbers
Every digit in Morse code is five signals long. Type any number to see it in standard Morse and in the short cut numbers operators often use.
Morse code numbers 0 to 9
| Digit | Standard Morse | Cut numbers (short form) |
|---|---|---|

| 2 | ||
| 3 | ||
| 4 | ||
| 5 | (often sent in full) | |
| 6 | ||
| 7 | ||
| 8 | ||
| 9 | ||
| 0 |
The pattern behind the numbers
Numbers are the easiest part of Morse code to learn because they follow a pattern. From 1 to 5 the dots grow from the left: 1 is one dot and four dashes (·−−−−), 5 is five dots (·····). From 6 to 0 the dashes grow from the left: 6 is one dash and four dots (−····), 0 is five dashes (−−−−−).
Cut numbers
Since the 1870s, operators have used an unofficial short form for numbers. It only works when both sides know numbers are expected, because the short forms are the same as some letters: every run of dashes is cut to a single dash and the dots stay the same, so 9 (−−−−·) becomes −· (the letter N) and 0 becomes − (the letter T). 4 and 6 do not change. Many operators still send 5 in full. The best-known example is the signal report 599, which radio amateurs send as 5NN.
Decimal points and long numbers
The converter keeps a decimal point as the Morse full stop (·−·−·−). Send long numbers in groups so the receiver can check them, and repeat them if they matter.
