What Is It and When Do You Need It?

The NATO phonetic alphabet makes spelling by voice reliable. B, D, P and T sound alike on a phone, but Bravo, Delta, Papa and Tango do not. It is used worldwide in aviation, shipping and customer service.

Type any text to see it spelled out, or paste NATO words to read the letters.

How to Use This Tool

  1. Type text or paste NATO words.
  2. Choose the direction and digit style.
  3. Press Run.
  4. Read the words aloud or copy them.

How the Calculation Works

Each letter A to Z is replaced with its code word from the standard list. Digits are replaced with the digit word. Spaces between words become a slash. Decoding matches each word to its letter, ignoring case.

Worked Example

Dev 42 becomes Delta Echo Victor / Four Two.
