I still remember the first time someone replied to me with “10-4” in a group chat. I stared at my screen wondering, “Is this a typo? A secret code? Did I miss something?” It felt like I had suddenly stepped into a police radio conversation instead of a normal chat.
If you’ve ever felt that confusion, you’re not alone. Even though 10-4 comes from old-school radio codes, it has become surprisingly common in texting, gaming, and online conversations.
Quick Answer:
10-4 means “Okay” or “Understood.”
It’s a clear, confident, and slightly formal way of saying you got the message.
🧠 What Does 10-4 Mean in Text?
In texting, 10-4 is a short way of saying:
- “Okay.”
- “Got it.”
- “Message received.”
It comes from ten-codes, a communication system used by police, truckers, and radio operators. Over time, it moved into casual online language — especially in gaming, teamwork chats, and organized groups.
Example:
A: I’ll meet you at the entrance in 5.
B: 10-4.
In short: 10-4 = Understood = I got your message clearly.
