Type a name or word and we'll spell it out using the NATO phonetic alphabet — standard for radio, aviation, military, and clear-line spelling.

The NATO phonetic alphabet (officially the International Radiotelephony Spelling Alphabet) replaces every letter with a code word that's impossible to mishear over a noisy line: Alpha, Bravo, Charlie, … Zulu.
Adopted by NATO in 1956, it's now the global standard for aviation, maritime, military, and amateur radio communication — and increasingly used by call-center agents and customer-service reps spelling unusual names.
"M as in Mike, A as in Alpha, R as in Romeo…" — far less ambiguous than "M as in Mark" (does the listener know how to spell Mark?). Banks, airlines, and customer support all use NATO phonetics.
Every aircraft callsign is read in NATO phonetics: "Speedbird Niner Foxtrot Romeo cleared to land." Paste your tail number to practice your radio call.
CQ calls, callsign exchanges, and contest logging all use NATO phonetics over voice. Required knowledge for licensing.
Tactical radio is full of letters — unit designations, callsigns, vehicle plates. NATO phonetics keeps every transmission unambiguous.
Reading a verification code over the phone? "Two-Tango-Niner-Whiskey" leaves zero room for mishearing.
"Nine" sounds too similar to the German nein over a crackling radio. Aviation/military convention pronounces it as "Niner" to disambiguate. Same reason "Tree" is sometimes used for "Three" ("three" can sound like "free").
The NATO alphabet only covers A–Z. Accented characters are passed through unchanged in this tool — handle them however your context requires (often by stripping accents first).
Yes. The US Army used the "Able Baker" alphabet before NATO standardized in 1956. "Tare" and "Item" survive in some old radio films. Modern police forces sometimes use APCO-replicating-letters ("A as in Adam"), which differs from NATO.
