Police and Emergency Radio Codes

Emergency services utilize various radio codes, such as 10-Codes and 11-Codes, to streamline communication during critical operations.

• Codes are not standardized nationally; departments often set up their own local code sets based on their specific needs.
• Historically, codes were used for security via obscurity, helping to obscure message details from those who were not privy to the information.
• Different types of codes exist, including 10-Codes, 11-Codes, Emergency Response Codes, and Vehicle Codes.
• The codes primarily function to accelerate message relay, providing quick and efficient communication between units.
