NATO Phonetic Alphabet Converter

The NATO phonetic alphabet — officially the International Radiotelephony Spelling Alphabet — assigns a standardised code word to each letter of the Latin alphabet (Alfa, Bravo, Charlie … Zulu) and spoken words for digits (Zero through Niner). It was developed by ICAO and NATO to eliminate ambiguity when spelling out words over voice radio or telephone, where similar-sounding letters such as B and D, or M and N, can easily be misheard.

Simply type any text into the input box and each character is instantly mapped to its NATO code word. The converter handles all 26 letters and the digits 0–9. It is widely used by pilots, air traffic controllers, military personnel, emergency services, and anyone who needs to communicate critical information — call signs, serial numbers, license plates, passwords — with zero chance of mishearing a letter.

How it works

Each letter A–Z is replaced by its designated NATO code word (A=Alfa, B=Bravo, … Z=Zulu). Digits 0–9 are replaced by spoken words (0=Zero, 1=One, … 9=Niner). Spaces between words are represented by a dash (—). Code words are joined by spaces.

Use cases

  • Spelling out call signs, tail numbers, or registration codes over radio
  • Communicating passwords or serial numbers by phone without ambiguity
  • Aviation and air traffic control communications
  • Military and emergency services radio operations
  • Teaching or learning the NATO phonetic alphabet interactively
