Understanding police codes can help you stay informed about law enforcement communications, emergencies, and day-to-day operations. In Texas, police officers use a combination of standardized and unique codes to streamline communication.
Knowing these codes can enhance your awareness of safety situations, emergency responses, and law enforcement activities. Below, we explore essential Texas police codes and their significance in everyday life.
What Are Police Codes and Why Do They Matter?
Police codes are shorthand signals used by law enforcement agencies to communicate information quickly and efficiently. These codes help officers convey important messages without lengthy explanations, ensuring fast and clear communication over radios.
The codes vary slightly between states and agencies, but some are widely recognized across the country.
In Texas, many police departments use a combination of the 10-code system and signal codes to categorize incidents and responses. These codes help dispatchers, officers, and emergency responders communicate effectively in high-pressure situations.
Commonly Used Texas Police Codes
10-Series Codes
The 10-code system is widely used across the United States, including Texas. Here are some of the most frequently used 10-codes:
- 10-4 – Acknowledgment (“Message received”)
- 10-7 – Out of service (off duty or unavailable)
- 10-8 – In service (available for calls)
- 10-9 – Repeat the message
- 10-20 – Officer’s location
- 10-23 – Arrived at the scene
- 10-33 – Emergency situation
- 10-50 – Traffic accident
- 10-78 – Requesting assistance
- 10-99 – Wanted or stolen vehicle/person
These codes allow officers to relay crucial information quickly without revealing too much over public airwaves, keeping communications efficient and secure.
Texas-Specific Police Codes
While many codes are universal, Texas law enforcement agencies also use unique codes specific to the state. Some of these include:
- Signal 1 – Officer needs immediate assistance
- Signal 5 – Armed suspect
- Signal 9 – Wanted person
- Signal 33 – Officer in danger
- Signal 100 – Emergency air (restricted radio communication)
Knowing these codes can be beneficial, especially if you monitor police scanners or follow local emergency updates. Understanding what an officer is referring to can give you insight into what’s happening in your community.
How Texas Police Codes Impact Everyday Life
1. Staying Informed About Emergencies
Being aware of common police codes allows civilians to stay informed during emergencies. For example, if you hear a 10-33 (emergency situation) or Signal 1 (officer in distress) on a scanner, you can be aware of high-risk incidents occurring nearby and take necessary precautions.
2. Enhancing Neighborhood Safety
Understanding police codes helps residents recognize crime trends and potential threats. If a dispatcher reports a Signal 9 (wanted person) or 10-50 (traffic accident) near your home, you can stay alert and avoid certain areas for safety.
3. Improving Communication with Law Enforcement
Knowing police codes can make it easier to interact with officers, especially if you’re reporting an emergency. Using the correct terminology, such as reporting a 10-50 (traffic accident) instead of simply saying “a crash happened,” provides clear and precise information that speeds up response times.
4. Assisting in Road Safety Awareness
Traffic-related police codes such as 10-50 (accident) and 10-99 (stolen vehicle) can help drivers stay informed about road conditions and potential hazards. Many police departments share real-time updates using these codes on public radio or social media.

The Evolution of Police Codes in Texas
Technology and communication methods have evolved, leading to some changes in how police codes are used. While many agencies still rely on traditional 10-codes and signal codes, some departments have shifted toward plain language communication.
The push for clear language aims to avoid confusion between different law enforcement agencies, especially during multi-agency operations or national incidents.
Despite these changes, traditional police codes remain widely recognized and used in Texas law enforcement.
