Spelling out a word letter by letter over a phone or radio connection is prone to mishearing — the NATO phonetic alphabet solves this with a standardized codeword for every letter and digit.
This tool translates any text into its NATO phonetic alphabet spelling, letter by letter.
How it works
Enter your text. Each letter and digit is looked up in the standard NATO codeword table (A = Alpha, B = Bravo, and so on), and a forward slash marks each space between words.

Examples
Spelling "SOS"
"SOS" translates to "Sierra Oscar Sierra" in the NATO phonetic alphabet.
Who should use it
- Spelling out names, codes, or addresses clearly over the phone.
- Learning or practicing the NATO phonetic alphabet.
Industry applications
- Aviation and maritime communications
- Customer service and call centers
Advantages
- Uses the exact, internationally standardized codeword set.
- Handles both letters and digits in one translation.
Limitations
- Only covers letters and digits, not punctuation or symbols.
Common mistakes to avoid
- Assuming every organization uses a slightly different phonetic alphabet — the NATO alphabet is the single, near-universal international standard.
- Forgetting that punctuation and symbols beyond letters and digits aren't translated, since they're not part of the standard alphabet.
Best practices
- Use the NATO phonetic alphabet whenever spelling something important over a phone call or radio, especially names, confirmation codes, or license plates.
Tips
- If you use the phonetic alphabet often (like reading out confirmation codes), memorizing just the trickier codewords — Alpha, Charlie, Juliett, Xray, Quebec — covers most of the letters people tend to forget.
