What is the NATO Phonetic Alphabet?
The NATO phonetic alphabet, officially known as the International Radiotelephony Spelling Alphabet, is a standardized spelling alphabet used by military, aviation, maritime, and telecommunications organizations worldwide. Each letter is assigned a specific code word (Alfa for A, Bravo for B, etc.) that is easily distinguishable from other letters when spoken over radio or telephone.
The alphabet was developed to prevent miscommunication, particularly when spelling out critical information like names, locations, or identification codes. For example, letters that sound similar (like "B" and "D" or "M" and "N") are given distinctive code words that are hard to confuse.
This free online tool converts any text into NATO phonetic alphabet spelling and can also decode phonetic words back into plain text. It supports multiple alphabet variants including the standard NATO/ICAO alphabet, police codes, and Western Union codes.

History of Phonetic Alphabets
Early Development (1920s-1930s)
Phonetic alphabets emerged with the growth of radio communication. The first standardized alphabet was adopted by the International Telecommunication Union (ITU) in 1927. Different organizations developed their own versions for specific needs.
World War II
During WWII, the U.S. military used the "Able Baker" alphabet (Able, Baker, Charlie, Dog...). The British RAF had their own version. Post-war standardization became necessary for international cooperation.
NATO Standardization (1956)
The current NATO phonetic alphabet was finalized in 1956 after extensive testing. Words were chosen to be easily understood by speakers of English, French, and Spanish, the three official languages of NATO at the time.
Frequently Asked Questions
What's the difference between NATO and ICAO alphabets?
They are the same alphabet. "ICAO" (International Civil Aviation Organization) refers to its use in aviation, while "NATO" refers to military use. The same code words are used in both contexts.
What are the Police/APCO codes?
The APCO (Association of Public-Safety Communications Officials) alphabet uses different words like Adam, Boy, Charles, etc. It was commonly used by police departments in the United States before many switched to the NATO alphabet.
How do I spell numbers phonetically?
Numbers are typically pronounced as their word equivalents: Zero, One, Two, Three, Four, Five, Six, Seven, Eight, Nine. Special care is taken with numbers that sound similar, like "Nine" (spoken as "NINER" in aviation to distinguish from "Five").
