Tips for Best Results
Pause between words
When speaking code words aloud, pause slightly between each one so the listener can write down each letter before the next.
Say 'I spell' first
Before spelling phonetically, say 'I spell' to alert the listener. Example: My name is Smith, I spell: Sierra Mike India Tango Hotel.
Use for confirmation codes
Phonetic alphabets are perfect for reading out booking references, serial numbers, and one-time codes over the phone.
Niner, not Nine
In NATO standard, the digit 9 is pronounced Niner to avoid confusion with the German word Nein, which means no.
Pick the right alphabet
Use NATO/ICAO for international communication, APCO for US police contexts, Western Union for telegraphy history, and Royal Navy for WWII-era reference.
Practice with your own details
Try spelling your name, address, and phone number until it becomes second nature. Start with NATO - it is the most widely recognized.
Use decode mode to verify
After encoding, switch to decode mode and paste the phonetic words back. If the output matches your original text, you know the conversion is correct.
Upload long text files
For long documents, use Upload or drag-drop a .txt file instead of pasting manually.
Check the breakdown table
In encode mode, scroll down to see a table showing each character, its code word, and pronunciation side by side.
