Phonetic Alphabet for Police and Emergency Services

Many UK police and emergency services use the NATO / ICAO phonetic alphabet for clear radio communication.

Last updated: 25 January 2026

What police and emergency services use

Clear spelling reduces errors in names, registrations and locations. The NATO / ICAO set is the most widely recognised alphabet today.

If you’re double-checking a plate, try the practice tool or the quiz for recall.

Common examples

  • Vehicle registration “AB12 CDE” → Alpha Bravo One Two Charlie Delta Echo
  • Incident ref “K9-407” → Kilo Niner Fower Zero Seven
  • Location “NW” → November Whiskey

Tips for radio clarity

  1. Say the code word, then pause: “Alpha … Bravo …”
  2. Use the numbers guide for Tree / Fower / Fife / Niner when required.
  3. Repeat back critical info (names, plates, postcodes).

Why Accuracy Matters

In this context, even a single misunderstood letter can cause delays, errors, or safety risks.

Real Examples

The phonetic alphabet ensures consistent understanding across teams and environments.

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.
