Numbers (aviation pronunciation in brackets)
This is the international (NATO/ICAO) spelling alphabet used by pilots, the military and call centres. The official spellings are Alfa and Juliett (you’ll also see Alpha and Juliet). The aviation toggle swaps in the radio pronunciations for numbers — “tree”, “fife”, “niner” — used to keep digits clear over a noisy frequency.

How do you say a booking reference phonetically?
Spell each character with its NATO code word — so “BA286” becomes “Bravo Alfa Two Eight Six”, and adding “as in” helps: “B as in Bravo, A as in Alfa”. The full alphabet runs Alfa, 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. Type yours above to spell it out.
Methodology: The phonetic alphabet is a fixed international standard (ICAO Annex 10), so this tool is pure reference data plus a deterministic converter — every code word is looked up, never inferred. It uses the official ICAO spellings (Alfa, Juliett, X-ray) and notes the common everyday variants. Numbers use the standard number words by default, with the aviation radio pronunciations (tree, fower, fife, niner …) available as a toggle. Letters keep their distinct sounds so they can't be confused over a phone or radio. How we test & calculate.
Because “B” and “P” sound the same on the phone
Try reading a booking reference down a bad line and you’ll hit it immediately: was that an M or an N, a B or a P, an S or an F? The phonetic alphabet exists to solve exactly this. Give every letter a word that sounds like nothing else — Bravo, Papa, Mike, November — and the ambiguity vanishes. Type what you need to spell above and you’ll get the code words instantly.
The traveller’s use case
It comes into its own on the phone with an airline or hotel: spelling your surname, reading back a confirmation code, giving a frequent-flyer number. “M as in Mike, N as in November” gets it right first time. It pairs naturally with the rest of the flying toolkit — the airline and aircraft code lookups, and the dialling-code tool for placing the call in the first place.
One standard, a few spellings
There’s just one phonetic alphabet in modern use — the NATO/ICAO one — though it travels under several names (military alphabet, aviation alphabet, police alphabet). The only quirks are the deliberate spellings Alfa and Juliett, and the aviation habit of pronouncing some numbers differently (“tree”, “fife”, “niner”) to keep them crisp over the radio. Both are covered here — the reference table shows every letter’s pronunciation, and the toggle switches the numbers between plain and radio styles.
Frequently Asked Questions
What is the NATO phonetic alphabet?
It’s the international radiotelephony spelling alphabet — Alfa, Bravo, Charlie, Delta and so on — a fixed standard (ICAO Annex 10) that gives every letter a distinct code word. The point is to spell things out so they can’t be misheard: “B” and “P” or “M” and “N” sound almost identical over a phone or radio, but Bravo and Papa never do. Pilots, the military, emergency services and call centres all use it.
Why is it useful when travelling?
Any time you have to spell something to someone who can’t see it — reading a booking reference or your surname to an airline or hotel over a crackly line, confirming a confirmation code, giving a registration. Saying “M as in Mike, N as in November” removes the guesswork. Type whatever you need above and read off the code words.
Is it “Alfa” or “Alpha”, “Juliett” or “Juliet”?
The official ICAO spellings are Alfa and Juliett — spelled that way deliberately. “Alfa” avoids speakers of some languages mispronouncing “ph”, and “Juliett” has the double-t so French speakers don’t treat the final t as silent. You’ll very often see the everyday spellings Alpha and Juliet, and they’re the same code words; this tool shows both.
What’s the aviation pronunciation option?
In aviation radio work some numbers are pronounced differently to keep them distinct over the air: three becomes “tree”, four “fower”, five “fife”, nine “niner”, and so on — “niner” in particular avoids any confusion with the German “nein”. Flip the aviation toggle and the tool spells numbers with those radio pronunciations; leave it off for the plain number words.
Is this the same as the “military alphabet”?
Yes — what people call the military alphabet, the aviation alphabet or the police alphabet is, in modern use, this same NATO/ICAO spelling alphabet. There were older systems (Able, Baker, Charlie… was used in the 1940s), but Alfa, Bravo, Charlie has been the single international standard since the 1950s, so it’s what virtually everyone means today.
