One space separates letters; a slash ( / ) separates words. A dot lasts one unit, a dash three — the timing rules are the same whether you write, beep, tap or flash the phrase. Every letter above follows the ITU International Morse Code standard, the same table as our full Morse code chart.
Fun ways to send a Morse birthday
- Puzzle link: press “Puzzle link” in the translator above — your friend gets the dots and dashes with the answer hidden behind a Reveal button.
- Inside the card: write the code across the inside of a birthday card and a tiny “decode this” note; link them to our decoder.
- As a ringtone or voice note: download the .wav above and send the beeps themselves — the message is the sound.
- On the cake or banner: dots and dashes piped in icing or drawn as a border spell the phrase in a pattern most guests will never crack.
Whatever the medium, keep the spacing honest: one space between letters, a slash between words. The gaps are half the message — without them, even a perfect code turns into guesswork.
