Practice Tips

  • Start with your name, postcode, or car registration — things you already know.
  • Say the letter first, then the code word: “A — Alpha”.
  • In noisy environments, keep a steady pace and avoid rushing.
  • For numbers, review UK vs ICAO on the numbers page.

How to Practice Effectively

Short, frequent practice sessions are more effective than long sessions. Focus on accuracy before speed.

Who This Is For

This practice tool is ideal for students, professionals, and anyone who needs reliable communication.

Convert Text to NATO Code Words

Enter any word, callsign, registration, or number sequence. The tool converts each character into its NATO phonetic equivalent. Use the Play button to hear the full phrase with a short pause between words.

More questions

Is the NATO phonetic alphabet the same worldwide?

Yes — it’s an internationally used standard across aviation, military, emergency services and radio communications.

Why not just spell normally?

Normal spelling is easy to mishear (“B” vs “D”, “M” vs “N”). Phonetic words make each letter unmistakable, even with noise or a weak signal.

Is this used in the UK?

Yes. In the UK it’s widely used in aviation and radio contexts, and it’s also handy for everyday phone calls and customer support.

Understanding the NATO phonetic alphabet

The NATO phonetic alphabet is a standardized spelling alphabet designed to make letters unmistakable when spoken aloud. Instead of saying just “B” or “D”, you say “Bravo” or “Delta”. The code words were selected because they are distinct, familiar, and easy to recognise across accents and in noisy conditions.

What it solves

  • Similar-sounding letters: B/D, M/N, S/F and others are often confused on phone lines.
  • Background noise: Radio chatter, traffic, or office noise can mask key sounds.
  • Accents and pronunciation differences: Standard code words reduce ambiguity.

When to use it

It’s ideal whenever accuracy matters: spelling names, email addresses, vehicle registrations, booking references, serial numbers, or anything that would be costly to get wrong.

How to use it correctly

Say the letter and the code word together (for example: “B — Bravo”). Keep a steady pace, and confirm the full word or code at the end if the listener repeats it back.
