NATO Phonetic Alphabet: Full A-Z Chart With Pronunciation
The NATO phonetic alphabet is a set of 26 code words, from Alfa to Zulu, that stand for the letters A to Z when you spell something out loud. Instead of saying “B” or “D”, which sound alike on a bad line, you say “Bravo” or “Delta”. As a result, names, codes and call signs get through clearly by radio, phone or in a noisy room.
- The NATO alphabet has 26 code words: 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.
- Its official name is the International Radiotelephony Spelling Alphabet, and ICAO, NATO and the ITU all use it.
- Official spellings are “Alfa” and “Juliett”; “Alpha” and “Juliet” are common English spellings.
- Numbers have their own pronunciations, such as TREE for 3, FIFE for 5 and NIN-ER for 9.

How to Say Numbers in the Phonetic Alphabet
Digits matter just as much as letters, because flight levels, phone numbers and grid references are full of them. So ICAO also set out how to pronounce each number. Several of them sound a little odd at first, but each change has a purpose.
| Number | Spoken As |
|---|---|
| 0 | ZE-RO |
| 1 | WUN |
| 2 | TOO |
| 3 | TREE |
| 4 | FOW-ER |
| 5 | FIFE |
| 6 | SIX |
| 7 | SEV-EN |
| 8 | AIT |
| 9 | NIN-ER |
| Decimal point | DAY-SEE-MAL |
| Hundred | HUN-dred |
| Thousand | TOU-SAND |
For example, “niner” stops 9 from sounding like the German “nein” (no), and “fife” keeps 5 apart from “fire”. Similarly, “tree” avoids the “th” sound, which many speakers find hard. Our guide to phonetic alphabet numbers covers decimals, large numbers and real examples.
Why the NATO Phonetic Alphabet Exists
Many English letters sound almost the same, especially over a radio. Think of B, D, E, G, P, T, V and Z, which all end in an “ee” sound. On a crackly line, “M” and “N” or “F” and “S” are also easy to mix up. A single wrong letter can send a parcel to the wrong place or, in aviation, a plane to the wrong runway.
The fix is simple. Each letter gets a full word that sounds unlike every other word on the list. Even if part of the word is lost, the listener can still tell “Foxtrot” from “Sierra”. Because the words are fixed and agreed in advance, everyone hears the same thing.
How the code words were chosen
The designers wanted words that speakers of English, French and Spanish could all say and recognize. For that reason, the list mixes everyday English words (Hotel, Golf) with names (Juliett, Romeo), places (Lima, Quebec) and dances (Foxtrot, Tango). Researchers also tested the words for clarity under noisy conditions before the list was finalized.
That international goal explains the unusual spellings. “Alfa” is spelled with an F so that speakers of other languages don’t say “Al-pa”. Likewise, “Juliett” has a double T so that French speakers don’t treat the final T as silent.
A Short History of the Phonetic Alphabet
Spelling alphabets go back to the early days of telegraph and radio. However, early versions varied from country to country and even between military branches. The British RAF, for instance, used words such as Ace, Beer and Charlie between the wars. Meanwhile, the US and UK forces in World War II used the “Able Baker” alphabet: Able, Baker, Charlie, Dog, Easy and so on.
Those older lists worked well for native English speakers but less well for everyone else. So, after the war, the International Civil Aviation Organization (ICAO) led work on a truly international alphabet. After several revisions, the version we use today came into use in the mid-1950s, and NATO adopted it around the same time. That’s why many people call it the NATO alphabet, even though aviation helped shape it.

Who Uses the NATO Phonetic Alphabet Today?
The same 26 words now turn up far beyond the military. Here are the main groups that rely on them every day:
- Pilots and air traffic controllers. Aircraft call signs, taxiways and waypoints are all spoken with the alphabet. See our aviation phonetic alphabet guide.
- Armed forces. Soldiers, sailors and aircrew use it for call signs, grid references and unit names. Our military alphabet page explains how.
- Ships and coast guards. Maritime radio follows the same standard, and the alphabet also names the international signal flags.
- Amateur radio operators. Hams spell their call signs this way on air, as our ham radio phonetic alphabet guide shows.
- Call centers and support teams. Agents use it to confirm names, emails and order numbers. Learn more in phonetic alphabet for customer service.
- Emergency services. Many fire and ambulance services use NATO words, although some US police still prefer the older APCO list. Compare them on our police phonetic alphabet page.
How to Pronounce the NATO Alphabet Correctly
Pronunciation matters because the whole system depends on everyone saying the words the same way. In normal speech, put the stress on the capitalized syllable in the chart. For example, Hotel is hoh-TELL, Papa is pah-PAH and Quebec is keh-BECK.
A few words trip people up:
- Charlie can be CHAR-lee or SHAR-lee; both are accepted.
- Quebec is keh-BECK, not kwuh-BECK, because the original sound follows French.
- Oscar and Victor end in “-cah” and “-tah” in the ICAO respelling, with no strong R.
- Papa stresses the second syllable, pah-PAH.
For a letter-by-letter breakdown, see the phonetic alphabet pronunciation guide.
Tip: When you spell something, say the letter first and then the code word, for example “S as in Sierra”. On the radio, though, trained operators usually say only the code words.
Using the Phonetic Alphabet in Everyday Life
You don’t need a radio to find the alphabet useful. Spelling your surname to a booking agent, reading a reference number to your bank or confirming a Wi-Fi password all go faster with it. In fact, many people learn it after one too many “Was that M or N?” moments on the phone.
Here’s a quick example. The name “Kate Ng” becomes:
Kilo, Alfa, Tango, Echo (space) November, Golf
Similarly, a code like “4B7” becomes “Fower, Bravo, Seven”. It takes a second longer to say, but it saves a lot of repeating.
How to Learn the NATO Alphabet Fast
Most people can learn all 26 words in a few days with short, regular practice. First, learn the words in blocks of five or six. Next, spell real things you see, such as car plates, street signs and product codes. Finally, test yourself until you can recall each word without pausing.
Our step-by-step plan on how to memorize the phonetic alphabet breaks this into a one-week routine. Then, when you’re ready, try the phonetic alphabet quiz to check your recall.
NATO Alphabet vs Other Spelling Alphabets
The NATO list is the international standard, but it isn’t the only spelling alphabet. For instance, some US police departments still use the APCO alphabet (Adam, Boy, Charles). In addition, several countries have their own national lists for everyday phone use, such as the German DIN 5009 alphabet.
It’s also easy to confuse the NATO spelling alphabet with the International Phonetic Alphabet (IPA). The two share a name but do very different jobs. The NATO list helps you spell letters clearly, while the IPA uses symbols to record the sounds of speech. If you’re studying pronunciation or linguistics, our IPA chart is the place to start.
Common Mistakes to Avoid
Even people who know the words make a few predictable slips. Fortunately, each one is easy to fix once you notice it.
- Making up your own words. “A as in apple” or “N as in Nancy” may feel natural, but the listener has to guess. Stick to the standard list so nobody needs to decode you.
- Rushing. Speak each code word clearly, with a short pause between them. Speed causes more errors than any accent.
- Skipping the numbers. Many people spell letters carefully and then mumble the digits. Use the ICAO number forms for long codes as well.
- Forgetting spaces and symbols. Say “space”, “dash” or “dot” out loud. Otherwise, “AB-12” and “AB12” sound exactly the same.
Radio users also pair the alphabet with procedure words such as “Roger”, “Wilco” and “Say again”. Our list of radio prowords explains what each one means. And if you’ve wondered where phrases like “Charlie Foxtrot” come from, our guide to military slang decodes the most common ones.
Key Takeaways on the NATO Phonetic Alphabet
The NATO phonetic alphabet turns 26 easily confused letters into 26 distinct words, from Alfa to Zulu. It began as an aviation and military tool, yet today it helps anyone who needs to spell clearly. Learn the chart, practice the numbers, and you’ll never have to say “B as in… um… boy?” again. For more detail, the International Civil Aviation Organization remains the official keeper of the standard.
Frequently Asked Questions
What is the NATO phonetic alphabet?
It is a list of 26 code words, from Alfa to Zulu, that represent the letters of the English alphabet. People use it to spell words clearly over radio or phone. Its official name is the International Radiotelephony Spelling Alphabet.
Is it Alpha or Alfa?
The official ICAO and NATO spelling is Alfa, chosen so that non-English speakers pronounce it correctly. Alpha is the common English spelling and you will see it often. Both refer to the same code word for A.
Why is it called the NATO alphabet?
NATO adopted the alphabet in the 1950s and its member forces use it widely. However, the civil aviation body ICAO played a major role in developing it. So you may also hear it called the ICAO alphabet.
Is the NATO phonetic alphabet the same as the military alphabet?
Yes. When people say military alphabet, they almost always mean the NATO phonetic alphabet. Armed forces in NATO countries and many others use the same 26 code words.
Why do pilots say niner instead of nine?
Niner is the ICAO pronunciation for 9. It helps keep the number distinct from similar sounds, such as the German word nein. Other numbers have special forms too, such as tree for 3 and fife for 5.
How long does it take to learn the NATO alphabet?
Most people learn all 26 words in a few days to a week with short daily practice. Spelling real words, like signs or plates, speeds things up. Regular quizzes then help the words stick.
