Spell With the NATO Alphabet

Spell Anything in the NATO Phonetic Alphabet

Type a word, a name, a confirmation code, or a whole sentence and get it spelled out in the NATO phonetic alphabet — A becomes Alpha, B becomes Bravo, and so on through the digits and common punctuation. Flip to reverse mode and it works the other way: paste code words like "Hotel Echo Lima Lima Oscar" and read the plain text back. Everything updates the instant you type.

You choose the spelling. The everyday forms (Alpha, Juliet, X-ray) are the default; switch to the official ICAO/NATO written forms (Alfa, Juliett, Xray) with one tap. The decoder is deliberately forgiving — it accepts either spelling, common aviation number words like "niner" and "tree," and simple punctuation names — and it flags any words it can't place instead of dropping them silently. A full A–Z, 0–9, and punctuation reference table sits right below the converter.

Honest caveat: this covers A–Z, the digits 0–9, and common punctuation. Multi-word punctuation names such as "Question Mark" spell out correctly but don't round-trip cleanly back through the decoder, and the tool is a spelling aid rather than a complete radio-procedure reference.

Common Use Cases

• Read a code over the phone: Spell a confirmation number, license plate, or serial so the person on the other end hears "Bravo," not "B — no, the other B."
• Support and call centers: Confirm names, emails, and case IDs without the endless "was that a B or a D?" back-and-forth.
• Radio, aviation, and marine: Practice or double-check callsigns and coordinates against the standard NATO/ICAO spelling.
• Dispatch and field teams: Turn an address or unit number into unambiguous code words that survive a noisy channel.
• Decode a spelled-out message: Paste the code words someone sent you and read the letters back as plain text.
• Learning and reference: See the whole alphabet at a glance and encode and decode both ways to commit it to memory.
