This tool follows the standard ICAO/NATO phonetic alphabet. It is designed for English characters and numbers. Non-alphanumeric characters may be passed through or ignored depending on the mapping.

• Why is it called NATO phonetic alphabet? The International Radiotelephony Spelling Alphabet was adopted by NATO in 1956 for use across all member nations. It was designed by ICAO to be universally pronounceable regardless of the speaker's native language, ensuring clear communication in aviation, military and maritime operations.
• Is Alpha or Alfa the correct spelling? The official ICAO/NATO standard uses Alfa (not Alpha) and Juliett (not Juliet). These non-English spellings were chosen deliberately so that speakers of French, Spanish and other languages would pronounce them correctly without confusion. In casual use, both spellings are understood.
• When should I use the NATO phonetic alphabet? Use it whenever you need to spell out text clearly over voice channels - reading serial numbers, confirmation codes, license plates, email addresses or passwords over the phone. It eliminates ambiguity between similar-sounding letters like B/D/P/T, M/N, and S/F, which are common sources of errors in verbal communication.
• Are there other phonetic alphabets? Yes. Before the NATO standard, the US military used Able-Baker-Charlie and the RAF used Alpha-Bravo-Charlie with different words. Police forces often use the APCO alphabet (Adam, Boy, Charles). The NATO/ICAO alphabet is the most widely recognized international standard and is used in aviation, shipping and telecommunications worldwide.
