NATO Phonetic Alphabet Converter
Convert text to NATO phonetic alphabet representation and vice versa.
About This Tool
The NATO Phonetic Alphabet Converter is a free browser-based utility that translates text into the standard NATO/ICAO phonetic alphabet and decodes phonetic words back into plain text. It supports the full set of 26 English letters (Alpha through Zulu) and the 10 digits (Zero through Nine) as defined by the International Radiotelephony Spelling Alphabet.
The NATO phonetic alphabet was adopted by NATO in 1956 and is formally known as the International Radiotelephony Spelling Alphabet. It assigns code words to each letter of the English alphabet so that spoken communication over radio, telephone, or noisy environments is clear and unambiguous. For example, "B" and "D" sound similar over a poor connection, but "Bravo" and "Delta" are easily distinguished. The alphabet is used worldwide by military forces, aviation (ICAO), maritime communication, law enforcement, emergency services, and customer service representatives.
This tool provides bidirectional conversion: type plain text to get the NATO phonetic spelling, or paste a sequence of phonetic words (such as "Alpha Bravo Charlie") to decode it back to letters. The reference table displays all 26 letters and 10 digits with their assigned code words. Use the swap button to quickly reverse the conversion direction.

What is the NATO phonetic alphabet?
The NATO phonetic alphabet, officially the International Radiotelephony Spelling Alphabet, is a set of 26 code words assigned to the 26 English letters: Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, and Zulu. It was adopted by NATO and ICAO in 1956 for clear radio and telephone communication.
Why is the NATO phonetic alphabet used?
The NATO phonetic alphabet exists to prevent miscommunication when spelling out words over radio, telephone, or in noisy environments. Letters like B/D, M/N, P/T, and S/F sound similar when spoken, but their NATO equivalents (Bravo/Delta, Mike/November, Papa/Tango, Sierra/Foxtrot) are clearly distinguishable.
Does this tool handle numbers?
Yes. The converter supports digits 0–9 using the standard NATO pronunciation: Zero, One, Two, Three, Four, Five, Six, Seven, Eight, Nine. In the NATO system, some numbers have modified pronunciations (e.g., 'Niner' for 9, 'Fife' for 5) in voice communication, though the standard English number words are used in this text-based tool.
What happens to punctuation and special characters?
Characters that are not in the NATO phonetic alphabet (such as punctuation marks, symbols, and non-English letters) are shown in brackets in the output, e.g., [!] or [,]. Spaces between words are represented by a forward slash (/).
What format should I use for NATO-to-text input?
When converting NATO phonetic words back to text, enter one code word per letter separated by spaces. Use a forward slash (/) to indicate a space between words. For example: 'Hotel Echo Lima Lima Oscar / Whiskey Oscar Romeo Lima Delta' decodes to 'HELLO WORLD'.
Is this the same as the ICAO phonetic alphabet?
Yes. The NATO phonetic alphabet and the ICAO (International Civil Aviation Organization) phonetic alphabet are the same system. It is also used by the ITU (International Telecommunication Union) and is the most widely recognized spelling alphabet in the world.
