If you’ve ever seen someone reply with “10/4” in a chat and you just sat there thinking… “uhh what does that even mean?” you’re definitely not alone. It looks like a date (October 4?), a math fraction (10 divided by 4?), or even some kind of secret code.
But then you notice people using it casually in texting, gaming chats, or even work radio-style talk, and it gets even more confusing.
Quick Answer:
10/4 means “Okay” or “Message received.” It’s a polite, clear, and slightly old-school way of saying you understand something or agree.
Let’s break down the real meaning of 10/4 and how people actually use it today 👇
What Does 10/4 Mean in Text?
The slang “10/4” comes from the old CB radio (citizens band radio) communication system used by truck drivers and emergency responders. In that system, “10 codes” were used to quickly send messages.
👉 “10-4” specifically means:
✔ “Message received”
✔ “Okay”
✔ “Got it”
✔ “I understand”
So instead of typing “okay” or “understood,” people would say “10-4.”
Example:
A: “Be there in 10 minutes.”
B: “10-4 👍”
This shows that the message was received and understood clearly.
In short:
10/4 = 10-4 = OK / message received / I understand.
