How to use it on a call
When clarity matters, spell each letter with a code word (A = Alpha, B = Bravo…). Say the word, then the letter if needed.
- Speak at a steady pace and pause between letters.
- Use the chart for letters and the numbers page for digits like Tree (3) and Niner (9).
- Confirm back: “That’s Bravo as in B, Alpha as in A…”

Examples
- Postcode “SW1A 1AA” → Sierra Whiskey One Alpha One Alpha Alpha
- Name “Khan” → Kilo Hotel Alpha November
- Reference “AB-409” → Alpha Bravo Fower Zero Niner
Tip: If the other person isn’t familiar, say “Alpha (A)” the first time and then just use the code words after that.

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.
