Before radio, before the telephone, America talked in clicks. This translator converts your text into American Morse code — the original telegraph code that ran along the railroads — and decodes it back into plain English.

Translate Text to American Morse Code

Type a message and it converts to American Morse code instantly, complete with the internal gaps and long dashes that make this code unique. Paste American Morse and the translator turns it back into readable text.

Press play to hear the rhythm of your message, or switch to visual mode to watch it signal. Copy the result or download the audio to use anywhere.

American Morse is not the same code most people learn today. If you're working with ham radio, aviation or a modern Morse chart, use the International Morse code translator instead.

The Code That Wired America

On May 24, 1844, Samuel Morse sent "What hath God wrought" over a telegraph line from Washington to Baltimore. The code he and Alfred Vail used became known as American Morse code.

Within a few decades, telegraph wires followed the railroads across the continent. Train orders, news, stock prices and personal telegrams all moved in American Morse, which is why it is still often called Railroad Morse.

Europe adopted a simplified version in the mid-1800s, which became International Morse code. American Morse held on across US and Canadian landlines well into the 20th century, and telegraph clubs still keep it alive today.

American Morse Code Alphabet & Numbers Chart

In the chart below, . is a dot, - is a dash, ⸺ is a long dash and ⸻ is an extra-long dash. A space inside a code is a deliberate pause, so .. . (C) is not the same as ... (S).

Letter	American Morse	Letter	American Morse	Number	American Morse
A	.-	N	-.	1	.--.
B	-...	O	. .	2	..-..
C	.. .	P	.....	3	...-.

Five letters carry internal spaces: C, O, R, Y and Z. L and 0 are the only characters made of a single long dash, with 0 held longer than L.

How to Read American Morse: Gaps, Long Dashes and Sounder Clicks

American Morse was built for the telegraph sounder, not the radio beep. A sounder makes a click when the circuit closes and a clack when it opens. Operators read the time between those two sounds, not a tone.

That's why the code has more than one kind of pause and more than one length of dash:

• A dot is the shortest signal; a dash is a little longer.

• A long dash stands alone as L, and an extra-long dash as 0.

• A space inside a letter is shorter than the space between letters.

• A space between letters is shorter than the space between words.

Trained operators heard these rhythms like speech. Many could copy 30 or more words per minute by ear while writing out the message by hand.

American Morse vs International Morse Code

Both codes use dots and dashes, but they are not interchangeable. A message sent in one system decodes as nonsense in the other.

	American Morse	International Morse
Also called	Railroad Morse, Morse telegraph code	Continental code, CW
Dash lengths	Dash, long dash (L), extra-long dash (0)	One dash length
Spaces inside letters	Yes — C, O, R, Y, Z	Never
Heard as	Clicks on a telegraph sounder	Tones over radio or a buzzer
Used today by	Telegraph clubs, historians, museums	Ham radio, aviation, emergency signalling

The simpler International system replaced American Morse on radio because spaced letters and multiple dash lengths are easy to garble over a crackling signal. On a quiet wire, though, American Morse is faster to send — one reason railroad operators loved it.

Frequently Asked Questions (FAQs)

1. What is American Morse code?

American Morse code is the original telegraph code developed by Samuel Morse and Alfred Vail in the 1840s. It was used on US and Canadian telegraph lines, especially by the railroads, which is why it's also called Railroad Morse.

2. What is the difference between American Morse and International Morse code?

American Morse uses spaces inside some letters and more than one dash length. International Morse uses one dash length and no internal gaps, and many letters and numbers are coded differently, so the two systems can't be read interchangeably.

3. Which letters are different in American Morse code?

The most distinctive are C, O, R, Y and Z, which contain internal spaces, and L, which is a single long dash. Letters such as F, J, P, Q and X, and most numbers, also use different patterns from International Morse.

4. Why is it called Railroad Morse?

Railroads were the biggest users of the telegraph in North America. Station operators sent train orders, schedules and messages in American Morse along wires that ran beside the tracks, so the code became closely tied to railroad work.

5. Why does American Morse code sound like clicks instead of beeps?

It was received on a telegraph sounder, a device that clicks when the circuit closes and clacks when it opens. Operators read the timing between those sounds rather than listening for a tone.

6. Is American Morse code still used today?

Not for everyday communication. It survives through telegraph clubs, museums, historical railroad demonstrations and hobbyists who restore antique telegraph keys and sounders.

7. Is American Morse code harder to learn than International Morse?

Usually, yes. Its internal spaces and multiple dash lengths demand precise timing, both to send and to hear. Most learners start with International Morse and move to American Morse if they get into historical telegraphy.

8. Can I convert International Morse code directly into American Morse?

Not symbol for symbol, because the two codes assign different patterns to many characters. Decode the International Morse to plain text first, then translate that text into American Morse here.
