The letter C is a chaos magnet on calls. Depending on accent and audio quality, “C” can blur into “D,” “G,” “T,” or just get clipped entirely. The NATO phonetic alphabet fixes that by making the letter longer, clearer, and way harder to mishear.
Letter: C
NATO code word: Charlie
Core purpose: Make “C” unmistakable in voice communication.
What does “Charlie” mean in the NATO phonetic alphabet?
Charlie is the standardized code word for the letter C in the NATO phonetic alphabet (used in aviation, radio comms, military-style procedures, and support calls). When you say “Charlie,” the listener should write C—no guessing.
How to pronounce “Charlie” correctly
A safe, consistent pronunciation:
- CHAR-lee (stress on the first syllable)
- Say both syllables clearly—don’t swallow the ending
In noisy environments, slightly slow down and separate it from adjacent words.
When to use “Charlie”
Use Charlie whenever a single wrong letter creates a different identity:
- Spelling names (especially “C/K/S” confusion)
- Email addresses and usernames
- Booking references, serial numbers, verification strings
- Radio communication and operational calls
- Customer support and account confirmation
If you start spelling with NATO words, keep it consistent through the whole sequence.
“Charlie” examples you can copy-paste
Spelling a name
- “It’s Charlie, then H, then A…”
Email address
- “Start with Charlie, then dot, then…”
Code / reference
- “The code is Charlie-4-8-Delta.”
Extra-clear confirmation

Best-practice phone/radio etiquette for “Charlie”
- Code word + letter if needed
“Charlie — C” helps if the listener isn’t familiar with NATO words. - One token at a time
“Charlie… Four… Tango…” beats speed every time. - Repeat critical strings
Repeat once, same pace, same order. - Avoid mixing alphabets
Don’t jump between NATO and “C as in Cat.” Pick one style and stick to it.
Common mistakes with C / Charlie
- Rushing so “Charlie” becomes “Char…”
- Not clarifying C vs K vs S in names (use NATO consistently)
- Skipping confirmation when the listener hesitates
