Spelling Alphabet Converter

Spell any text using the NATO/ICAO phonetic alphabet (Alfa, Bravo, Charlie...) live as you type, plus a full A-Z and digit reference table.

Source Text

Digits use their real radiotelephony words: 3 is “Tree”, 4 is “Fower”, 5 is “Fife” and 9 is “Niner” — deliberately different from normal English so they are never misheard as another number.

Only letters A–Z and digits 0–9 are spelled out; punctuation and other characters are skipped.

Result

This page opens the NATO phonetic alphabet converter under its other common name: a spelling alphabet, the general term for any system that gives every letter its own distinct word so it survives a noisy phone line or radio channel.

The NATO/ICAO version — Alfa, Bravo, Charlie, Delta... — is the one most widely recognized worldwide, adopted by aviation, the military and countless call centers precisely because its words are hard to confuse with one another in any language.

Type a name, an email address or a confirmation code above and it is spelled out instantly as you type; the full A-Z and digit table plus two other countries' spelling alphabets stay visible below for reference.

Key Benefits

✓ Live conversion: type any word or callsign and see it spelled out in the official NATO/ICAO code words instantly, with no button to press.

✓ Accurate digit forms: numbers use the real radiotelephony words (Tree, Fower, Fife, Niner) instead of plain English digits, exactly as pilots and radio operators say them.

✓ Two more alphabets for reference: the German DIN 5009 and French telephone spelling alphabets sit right below, for comparison.

Use Cases

• Read a confirmation code, license plate or callsign over the phone without it getting misheard: type it and read back the NATO/ICAO code words instead of the raw letters.
• Study for an amateur radio license or dispatch/radio-operator training: the always-visible A-Z and digit table plus the honest note on digit pronunciation (Tree, Fower, Fife, Niner) doubles as a quick-reference sheet.
• Compare spelling alphabets across countries: the German DIN 5009 and French telephone alphabet tables sit right below the NATO/ICAO one for reference.
