Morse Code Numbers 0 to 9
Every digit in Morse code is exactly five signals long and follows one simple rule, which makes the numbers the easiest part of the whole code to learn. Listen to each digit, translate any number, and see how operators send years, phone numbers and popular codes like 67 and 143.

The ten digits, with sound
Tap a digit to hear it. Each one is five signals long: dots fill in from the left for 1 to 5, dashes fill in from the left for 6 to 0.
One rule for all ten
The five-signal pattern
Read the table top to bottom and watch the dashes march across. Once you see it, you never need to memorize the digits individually again.
| Digit | Code | Pattern | Rule | |
|---|---|---|---|---|
| 1 | .---- | one dot, then four dashes | ||
| 2 | ..--- | two dots, three dashes | ||
| 3 | ...-- | three dots, two dashes | ||
| 4 | ....- | four dots, one dash | ||
| 5 | ..... | five dots | ||
| 6 | -.... | one dash, four dots | ||
| 7 | --... | two dashes, three dots | ||
| 8 | ---.. | three dashes, two dots | ||
| 9 | ----. | four dashes, one dot | ||
| 0 | ----- | five dashes |
Tool
Morse code number translator
Type any number: a year, a phone number, your lucky number. Digits are converted one by one; letters and punctuation work too.
Need the other direction? Paste dots and dashes into the Morse code decoder to turn them back into numbers.
67, 143, 73 and more
Popular numbers in Morse code
The numbers people look up most, ready to play and copy. Digits inside a number are separated by a normal letter gap (three units); a slash marks a word gap.
67
-.... --...
The most searched number in Morse code right now. Two digits, ten signals: a dash and four dots, then two dashes and three dots.
143
.---- ....- ...--
Old pager and texting shorthand for "I love you": the digits are the number of letters in each word (I = 1, love = 4, you = 3).
73
--... ...--
Telegraph and ham-radio shorthand for "best regards". Operators send it at the end of a contact.
88
---.. ---..
"Love and kisses". A warmer sign-off than 73, traditionally sent to a close friend or partner.
911
----. .---- .----
The US emergency number. In a real emergency, SOS (... --- ...) is the signal that every rescuer recognizes.
2026
..--- ----- ..--- -....
A year is sent digit by digit, never as "twenty twenty-six". Four digits, twenty signals.
10
.---- -----
There is no single code for ten: it is 1 followed by 0, with a normal letter gap between them.
100
.---- ----- -----
One, zero, zero. Larger numbers are always spelled out one digit at a time.
250
..--- ..... -----
Two, five, zero. The 5 (five dots) sits between the 2 and the 0 (five dashes), the two extremes of the pattern.
Advanced
Cut numbers: the operators' shortcuts
Because full digits are long, radio operators in contests and traffic nets often replace them with shorter letters that share the same "shape". These are not part of the ITU standard, so use them only where both sides expect them.
| Digit | Full code | Cut | Sent as | Saves |
|---|---|---|---|---|
| 0 | ----- | T | - | 16 units |
| 1 | .---- | A | .- | 12 units |
| 2 | ..--- | U | ..- | 8 units |
| 3 | ...-- | V | ...- | 4 units |
| 4 | ....- | 4 | ....- | — |
| 5 | ..... | E | . | 8 units |
| 6 | -.... | 6 | -.... | — |
| 7 | --... | B | -... | 4 units |
| 8 | ---.. | D | -.. | 8 units |
| 9 | ----. | N | -. | 12 units |
Practical
How to send dates, years and phone numbers
Every number, however large, is sent one digit at a time. There is no code for "ten", "hundred" or "thousand"; 1,000 is simply .---- ----- ----- -----. Commas and thousand separators are dropped.
Years and dates
Send a year as four digits with normal letter gaps: 1844 (the year of the first telegraph message) is .---- ---.. ....- ....-. For a full date, separate the parts with a word gap (written as a slash) or with the hyphen character -....-: May 24, 1844 could be sent as ..--- ....- / ..... / .---- ---.. ....- ....-. The fraction bar -..-. is the official ITU code for "/" if you want to write 24/5/1844 literally, although in practice operators just leave a gap.
Phone numbers
A phone number such as 555-0199 is sent as ..... ..... ..... -....- ----- .---- ----. ----., with the hyphen sent as its own character (-....-), or more simply as groups of digits separated by word gaps: ..... ..... ..... / ----- .---- ----. ----.. Because digits are long, operators often repeat numbers twice for safety.
Zero versus the letter O
In Morse code there is no confusion between 0 and O, unlike in handwriting: 0 is five dashes (-----) and the letter O is three (---). Listen for the extra two dashes.
Numbers 1 to 100
People often search for "Morse code numbers 1-10" or "1-100", expecting a hundred separate codes. There are only ten: every number from 1 to 100 is a combination of the digits above. 10 is .---- -----, 50 is ..... -----, 100 is .---- ----- -----. Learn the ten digits and you can send any number.
FAQ
Frequently asked questions
How do you write numbers in Morse code?
Each digit from 0 to 9 is a fixed group of five dots and dashes: 1 is .----, 2 is ..---, 3 is ...--, 4 is ....-, 5 is ....., 6 is -...., 7 is --..., 8 is ---.., 9 is ----. and 0 is -----. Multi-digit numbers are sent one digit after another with a short gap between them.
What is 67 in Morse code?
67 in Morse code is -.... --...: the 6 is one dash followed by four dots, the 7 is two dashes followed by three dots. Press play in the "popular numbers" section above to hear it.
Is there a trick to remember Morse code numbers?
Yes, and it is the easiest trick in the whole code. Every digit has five signals. From 1 to 5 the dots fill in from the left (1 = one dot, 2 = two dots, and so on) and the rest are dashes. From 6 to 9 the dashes fill in from the left (6 = one dash, 7 = two dashes) and the rest are dots. 0 is five dashes.
How do you write 10 or 100 in Morse code?
There is no special code for ten or a hundred. 10 is 1 then 0: .---- -----. 100 is .---- ----- -----. Any number from 1 to 100, or to a million, is just its digits in order.
What is the difference between 0 and the letter O in Morse code?
The digit 0 is five dashes (-----); the letter O is three dashes (---). They sound related but are easy to tell apart once you count: the zero is almost twice as long.
Why do radio operators send 5NN instead of 599?
Those are "cut numbers": letters that replace digits to save time. N (-.) stands in for 9 (----.), T for 0, A for 1 and so on. They are an informal convention among experienced operators, not part of the official ITU standard.
Now learn the letters
With the ten digits done, the alphabet is the next step. Every letter has audio and a memory trick.
