🚨 What Are Police Radio Codes?

Police use radio codes to quickly and clearly communicate over the radio. These codes:

• Save time in emergencies

• Maintain clarity in high-stress situations

• Help conceal sensitive information from the public

There are multiple types of radio codes:

• 10-Codes (like 10-4 = acknowledged, 10-33 = emergency)

• Penal Codes (like 211 = robbery, 187 = homicide)

• Local agency codes, which can vary city to city

📡 What Scanner Should You Use?

To follow scanner traffic clearly, you need a reliable device. I personally use the Uniden SDS100 handheld scanner — it’s one of the most powerful and easy-to-program scanners on the market today.
