Morse Code Alphabet & Symbols Chart
An interactive A–Z and 0–9 reference with copyable International Morse sequences.
International Morse Code Letters: A–Z
Morse Code Numbers Reference: 0–9
How This 36-Character Reference Is Organized
The interactive grid above contains 26 Latin letters and 10 numerals from the International Morse table. Tap or focus a card and activate it to copy that exact sequence. Punctuation is intentionally kept out of this compact grid; use the translator when you need a supported punctuation mark.
Letter Lengths at a Glance
The alphabet is not a list of equally long codes. Grouping letters by signal count makes the structure easier to check and gives you smaller practice sets.
| Signals per letter | Letters | Count |
|---|---|---|
| 1 | E, T | 2 |
| 2 | A, I, M, N | 4 |
| 3 | D, G, K, O, R, S, U, W | 8 |
| 4 | B, C, F, H, J, L, P, Q, V, X, Y, Z | 12 |
This grouping is derived directly from the map rendered on this page. It is useful for checking completeness: 2 + 4 + 8 + 12 accounts for all 26 Latin letters.
The Numeral Pattern
Every numeral uses five signals. From 1 to 5, leading dots increase while trailing dashes decrease: .----, ..---, ...--, ....-, ...... From 6 to 0, leading dashes increase while trailing dots decrease: -.... through -----.
Spot Checks Used for This Grid
| Character | Rendered sequence | Reason for check |
|---|---|---|
| E | . | Shortest dot code |
| T | - | Shortest dash code |
| S | ... | SOS component |
| O | --- | SOS component |
| Q | --.- | Four-signal mixed pattern |
| 5 | ..... | All-dot numeral |
| 0 | ----- | All-dash numeral |
Scope and Source
The A–Z and 0–9 assignments are checked against ITU Recommendation M.1677-1. Language extensions such as Ñ or Arabic letters are documented on their own translator pages because they are not part of this compact Latin-letter grid.
A visual chart is useful for lookup, but listening practice is a different task. Use the audio player to hear timing, or the practice quiz to test recall without looking at the table.
Alphabet Reference Questions
Reading direction and boundaries
Read each character from its first signal to its last, then pause before the next character. The printed space between cards is a visual aid; in sound, timing creates the boundary. Reversing a pattern changes the letter—for example, A is .- while N is -..
Two lookup walkthroughs
Example 1 — CODE: find C (-.-.), O (---), D (-..) and E (.), then keep one letter boundary between groups: -.-. --- -.. ..
Example 2 — 907: look in the numeral grid for 9 (----.), 0 (-----) and 7 (--...). The complete group is ----. ----- --....
Use the grid as a correction sheet during practice, a quick reference while decoding a puzzle, or a source for building short listening drills. For transmitted text, learn the rhythm rather than treating every symbol as a visual drawing.
