What Is the NATO Phonetic Alphabet?
The NATO phonetic alphabet (officially the International Radiotelephony Spelling Alphabet) is a standard set of code words for communicating over unclear call channels. Each letter A--Z has a corresponding phonetic code word, for example, A = Alfa, B = Bravo, and Z = Zulu. So instead of saying "B as in boy", operators say "Bravo", which is easier to hear on a noisy channel.
NATO adopted the current version of the alphabet in 1956. Today, it's used worldwide by militaries, civilian aviation, maritime services, amateur radio operators, and emergency dispatchers.

FAQs
Does the NATO alphabet support numbers and punctuation?
Partly. The alphabet is mostly for letters, but you can spell out numbers ("one", "two", etc.) to communicate digits.
Punctuation is not part of the core alphabet, so users may use different symbol names like "slash", "dash", and "dot" depending on context.
Does the NATO alphabet work in other languages?
Yes, but users often replace non-English letters with their closest equivalent, so Ü becomes U and Ç becomes C, for example.
Some languages also use a different set of NATO words. In German, A is Anton, B is Berta, C is Cäsar, and so on. Turkish speakers use city names: A is Adana, B is Bolu, and C is Ceyhan, etc.
NATO phonetic alphabet vs Morse code: Which is better?
Both systems solve the same problem, which is to make radio communications more reliable. However, they suit different environments.
- The NATO alphabet is effective when you have a reasonable audio connection.
- Morse is better in very limited communication environments. It can also work visually with just flashes of light.
The table below shows the NATO word alongside the Morse code for every letter and number.
