Emergency service response codes are a set of codes used by emergency services to communicate information quickly and efficiently. These codes are used by police, fire departments, emergency medical services (EMS), and other emergency response organizations. The codes can vary by region and agency, but they generally serve the same purpose: to convey important information succinctly and clearly.

Types of Codes

Emergency service response codes can be broadly categorized into several types:

10-Codes

10-codes are a system of numeric codes that represent common phrases. They are widely used by law enforcement agencies in the United States. Examples include:

• 10-4: Acknowledgment
• 10-20: Location
• 10-33: Emergency, all units stand by

Signal Codes

Signal codes are another type of numeric code used by some emergency services. These codes often vary significantly between different agencies. Examples include:

• Signal 1: Officer needs assistance
• Signal 13: Major disaster

Code Colors

Code colors are used primarily in hospitals and other medical facilities to indicate specific types of emergencies. Examples include:

• Code Blue: Medical emergency, such as cardiac arrest
• Code Red: Fire or smoke

Plain Language

Some agencies have moved towards using plain language instead of numeric or color codes to avoid confusion, especially in multi-agency responses. This approach is supported by the National Incident Management System (NIMS).

Usage by Different Services

Police

Police departments often use 10-codes and signal codes to communicate status updates, requests for backup, and other critical information. The specific codes can vary by jurisdiction.

Fire Departments

Fire departments may use a combination of signal codes and plain language. They often have specific codes for different types of fires, hazardous materials incidents, and rescue operations.

Emergency Medical Services

EMS providers use a variety of codes to communicate patient status, types of medical emergencies, and other critical information. Code colors are commonly used in hospital settings to indicate different types of emergencies.

Regional Variations

The specific codes used can vary widely between different regions and agencies. For example, the California Highway Patrol uses a different set of 10-codes than the New York Police Department.
