Decimal The point inside a number. Said DAY-SEE-MAL, every syllable stressed alike, so 7.5 is Seven Decimal Five. The FAA says point.
Hundred Said HUN-dred. For whole hundreds only, when 00 ends a number that is a quantity: a code or serial number is still read digit by digit.
Thousand Said TOU-SAND, without the th, for the same reason as TREE. Used as in English, for quantities and not for codes.

Punctuation (military list) 6

Stop A full stop that is not a decimal point.
Comma A comma that is not a decimal comma. Written for ",".
Hyphen The FAA says dash. Written for "-".
Slant The forward slash. This page marks your own word breaks with a slash too, so a typed one is always written out as Slant. Written for "/".
Brackets on An opening bracket. Written for "(".
Brackets off A closing bracket. Written for ")".

How this list was compiled: All 55 code words and every respelling were read from the Wikipedia article NATO phonetic alphabet (https://en.wikipedia.org/wiki/NATO_phonetic_alphabet) on 2026-09-19, and each is in the article as typed here. The article takes the 26 letter words, the 10 digit words and their English respellings (capitals mark a stressed syllable) from ICAO Annex 10, Volume II, section 5.2; the 10 compound digit words from the ITU Radio Regulations and the IMO International Code of Signals; and the 6 punctuation words from the Combined Communications-Electronics Board publication ACP 125(G). The list of 26 was checked a second time against NATO's own history page, The NATO phonetic alphabet (https://www.nato.int/cps/en/natohq/declassified_136216.htm), read the same day, which also gives the five words the 1956 version replaced (Coca, Metro, Nectar, Union, Extra). Spellings are ICAO's: Alfa, Juliett and X-ray. The variants a listener may say or type (Alpha, Juliet, Xray, Whisky, Niner and the like) are kept only so the decoder accepts them. In: every code word those bodies publish for a letter, a digit, a number or a punctuation mark. Left out: national and police variants, earlier alphabets such as Able Baker, and the procedure words of radio (over, roger, wilco), which are not a spelling alphabet. Licence: own work

How it works

This NATO phonetic alphabet converter, or phonetic alphabet translator, spells a name or reference as code words, Alfa for A through Zulu for Z, and reads them back. The chart holds 55 words. It spells letters and translates no words.

Spell a line, or read one back

Type a name or a booking reference and each letter becomes its word, with a slash where your own words break. Swap reads code words back, and it accepts the everyday Alpha, Juliet and Niner. The list under the tool gives the respellings ICAO publishes, capitals marking the stress: ho TELL, keh BECK, see AIR rah.

NATO phonetic alphabet numbers, in two sets

Aviation and NATO keep the English digits and bend four: 3 is TREE, 4 is FOW-er, 5 is FIFE and 9 is NIN-er. Ships have a second set of compounds, such as Nadazero, Unaone and Bissotwo. This page spells digits the aviation way and reads both sets back. A number is read digit by digit: 17 is One Seven.

Alfa and Juliett are not typos: ph is not f in every language, and French speakers may read a single final t as silent.
A point between digits is Decimal: 7.5 is Seven Decimal Five. A sentence’s full stop is Stop, but this page writes Decimal for both.
Hundred and Thousand are for quantities: 1300 is One Three Zero Zero as a transponder code, One Thousand Three Hundred as an altitude.

Questions and answers

Is it really NATO's alphabet?

By nickname only. Its formal name is the International Radiotelephony Spelling Alphabet, and ICAO, the civil aviation body, put the final version into use on 1 March 1956. NATO’s own history page says its allies led the last revision, which replaced five words.

Is this a phonetic spelling generator?

Only in the radio sense. In a dictionary, a phonetic spelling writes a word the way it sounds, and a phonetic spelling converter or translator of that kind is another tool. This page spells with code words, one for each letter.

How do I spell my name phonetically?

Type it above and read the code words out one at a time: Sam is Sierra Alfa Mike. Capitals and small letters give the same words.

What is P in the phonetic alphabet?

Papa. K is Kilo, T is Tango and H is Hotel. All 26 letter words are in the table under the tool, each with its respelling.

Is this the military alphabet?

Yes, if you mean the one NATO forces use: NATO adopted these same 26 words. Older military lists differ. The United States alphabet of 1941 was known as Able Baker, after its words for A and B.
