NATO Phonetic Alphabet

The NATO phonetic alphabet (officially: ICAO/ITU phonetic alphabet) assigns code words to each letter of the Latin alphabet — Alpha for A, Bravo for B, Charlie for C, etc. It was standardized in 1956 by NATO and the International Civil Aviation Organization (ICAO) to minimize errors in voice communication, especially over radio where static, accents, and interference can make similar-sounding letters (B/D/G, M/N, P/T) indistinguishable. Used by aviation, military, police, maritime, and emergency services worldwide.

The words were chosen to be: (1) Easily recognizable across different languages and accents. (2) Phonetically distinct from each other — no two code words sound similar. (3) Known words in most major languages. Earlier versions had issues: the 1938 CCIR alphabet used "Able Baker Charlie" (US military), but "Able" and "Abel" caused confusion and some words sounded too similar in non-English languages. The 1956 ICAO revision replaced problematic words — "Alfa" (not "Alpha") was chosen so Spanish/Portuguese speakers wouldn't stress the "ph", and "Juliett" has two t's to indicate stress.

When spelling out a word over radio or phone: say the word, then spell it using code words. "My name is Smith — Sierra Mike India Tango Hotel." Or just spell directly: "Whiskey Kilo Delta". For numbers, use: one (won), two (too), three (tree), four (fower), five (fife), six, seven, eight, niner (not nine, to avoid confusion with German nein), zero. When transmitting over poor-quality channels, also say letters individually then phonetically: "S — Sierra".

British Forces: Similar but with some differences — "Ace" instead of "Alpha" in earlier versions. LAPD/Police: Some US police departments use "Adam Baker Charles David Easy Frank George" (derived from the 1938 APCO alphabet). Aviation vs. Military: Both now use the standard ICAO alphabet. Amateur (Ham) Radio: Also uses the ICAO alphabet but historically used "Adam, Baker, Charlie..." International versions: Many countries have their own versions for domestic communication, but ICAO is universal for international aviation and maritime.

NATO digit pronunciation (for radio clarity): 0 = Zero (ZEE-ro). 1 = One (WUN). 2 = Two (TOO). 3 = Three (TREE). 4 = Four (FOW-er). 5 = Five (FIFE). 6 = Six (SIX). 7 = Seven (SEV-en). 8 = Eight (AIT). 9 = Nine (NIN-er). The unusual pronunciations of 3, 4, 5, and 9 reduce confusion: "tree" vs "three" avoids confusion in non-English environments; "niner" prevents confusion with the German "nein" (no); "fower" avoids confusion with "for".
