What Are Police Scanner Codes? 🎙️
Police scanner codes are short, standardized radio codes used by law enforcement, firefighters, and emergency responders to communicate quickly and efficiently.
Why use codes? Speed & clarity! Instead of saying, “We need an officer at Main Street and 5th Avenue for a suspicious person report,” officers can simply say, “10-20, suspicious activity.” Boom—message received.
There are two main types of police scanner codes used in the U.S.:
1. 10-Codes (Ten-Codes)
These are universal shortcodes used by most law enforcement agencies. You’ll hear them on almost any police radio scanner across the country.
2. Signal Codes & Local Variants
Some police departments ditch the 10-codes in favor of signal codes, department-specific codes, or plain English. Always check your local police scanner frequency list to know which system your local PD uses.
Common Police Scanner 10-Codes 📻
Below is a cheat sheet of the most commonly used police scanner 10-codes in the United States. 🚔
| 10-Code | Meaning |
|---|---|
| 10-1 | Weak signal / Poor reception 📡 |

🛑 Important: Codes can vary by state & city, so always double-check your local police radio scanner guide for region-specific codes.
Understanding Local Police Signal Codes 🚦
Some departments use signal codes instead of 10-codes. These vary by location, but here are a few examples:
🔹 Signal 1 – Officer needs assistance 🚔
🔹 Signal 5 – Homicide investigation 🔍
🔹 Signal 13 – Suspicious activity 🕵️♂️
If you’re serious about listening, take some time to research local police frequencies & codes to get the full picture.
