NATO Phonetic Alphabet Translator

How to use

1. 1Type or paste a name, license plate, code, or confirmation number to encode it as NATO words. Paste a NATO sequence (Alpha Bravo Charlie) to decode it back to letters. Auto-detect picks the direction.
2. 2Pick a digit mode: NATO aviation (Tree, Fife, Niner) for radio and aviation work, or plain spoken (Three, Five, Nine) for customer service and business calls.
3. 3Choose an output separator (space, new line, dash, or pipe) to match where you will paste the result, then read the translation on the right and copy it with one click.
4. 4Enable Spell out punctuation when you need stops, commas, dashes, or slashes spelled out. Use Use output as input to round-trip a translation back through the encoder for verification.
5. 5Open the reference chart at the bottom to look up any letter, both digit pronunciations, or the supported punctuation labels.

About this tool

NATO Phonetic Alphabet Translator is a bidirectional translator between plain text and the NATO phonetic alphabet, formally the International Radiotelephony Spelling Alphabet adopted by the ICAO in 1956 and used by NATO, the ITU, the FAA, the IMO, police and emergency services, customer-service agents, and aviation, military, shipping, and amateur radio communities worldwide. The tool runs entirely in your browser, auto-detects direction so you can paste either plain text or a sequence of NATO code words and get the right result, and locks the direction manually when you want to override. Encoding maps every A-Z letter to its standard code word (Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu) and supports two digit modes: NATO aviation pronunciations (Tree for 3, Fife for 5, Niner for 9, used so digits cannot be confused with similar-sounding numbers over a noisy radio) and plain spoken digits (Three, Five, Nine, used in business and customer-service contexts). Output separator is configurable: a single space for spoken phrasing, one word per line for vertical lists, dashes or pipes for inline logs and chat messages. Decoding accepts the most common alternate spellings (Alfa for Alpha, Juliet for Juliett, Whisky for Whiskey, Xray for X-ray) and is tolerant of mixed separators (spaces, slashes, pipes, dashes, commas, and newlines) so NATO sequences pasted from training materials, customer-service scripts, manifests, and chat logs decode without manual cleanup. An optional spell-out mode encodes punctuation as labeled tokens like (Stop), (Comma), (Dash), and (Slash) using the same labels FAA and military training materials publish. A complete reference chart at the bottom shows every letter and its code word, both digit modes side by side, and the supported punctuation labels, making the page useful as a quick reference even without a translation in progress. Useful for spelling out names, addresses, license plates, confirmation numbers, IATA airport codes, callsigns, ticket numbers, order IDs, and email handles over the phone or radio without misunderstanding; for training new customer-service, dispatch, or air-traffic-control staff; and for verifying you and the person on the other end of the line are reading exactly the same string. Translation runs locally on your device, so the names, codes, and confirmation numbers you spell out here are never uploaded.
