What Is a 42.12 Police Code? 42.12 Police Code
The 42.12 police code meaning for the police forces is Discharge of Firearm in Certain Municipalities.
The 42.12 Police Code refers specifically to the offense known as Discharge of Firearm in Certain Municipalities. This police code is used by law enforcement agencies to identify and communicate incidents where an individual unlawfully discharges a firearm within specific city or municipal boundaries that have restrictions in place. The usage of the 42.12 police code allows officers to instantly report such incidents over radio communications in a standardized and time-efficient manner. Instead of describing the full nature of the violation, dispatchers and officers can simply state “42.12” to refer to this firearm-related offense, reducing the risk of miscommunication during high-pressure or time-sensitive situations.
The Role of the 42.12 Police Code in Law Enforcement Communications
Police codes like 42.12 are part of a broader system developed to streamline communication across departments and jurisdictions. These codes were first introduced between 1937 and 1940 as part of the APCO Ten Signals, which were later expanded in 1974 by the Association of Public-Safety Communications Officials-International (APCO) to include a wide range of numeric shorthand. The 42.12 code specifically falls under statutes related to offenses against public order and safety, and its use is especially important in areas with densely populated residential zones or local ordinances aimed at reducing gun-related disturbances.
Municipalities that enforce regulations around the discharge of firearms typically do so to protect citizens from accidental harm, maintain public peace, and prevent reckless behavior. The 42.12 police code enables swift identification of such violations, triggering immediate police response, potential investigations, and appropriate legal action. In most areas where this code is in effect, discharging a firearm without legal justification—such as self-defense or by authorized personnel—can result in criminal charges, especially if it poses a risk to public safety.
What Is Discharge of Firearm in Certain Municipalities? Police Code Explanation
When asking, what is 42.12 Police Code, it’s essential to understand that the term Discharge of Firearm in Certain Municipalities refers to a violation where an individual fires a gun within areas that prohibit such action under local law. These areas are often defined by population size, zoning classification, or proximity to homes, schools, or businesses. For example, in many states across the U.S., cities with populations exceeding 100,000 residents may have standing ordinances that prohibit firearm discharge within city limits unless the shooter is within a licensed range or is a law enforcement officer on duty.
The 42.12 code empowers officers to quickly log and respond to these dangerous situations. It also ensures that departments maintain accurate records for statistical reporting, legal prosecution, and public safety initiatives. If you’re using a police scanner, hearing “42.12” called out indicates that an officer is dealing with an incident involving an unauthorized firearm discharge in a regulated area. Such offenses often lead to fines, misdemeanor or felony charges, and, in some cases, the confiscation of the weapon involved.

The Role and Evolution of Police Codes, Including 42.12
The 42.12 Police Code, like many others in the 42-series, is used to represent specific violations or incidents concisely. Police codes originated in the late 1930s, specifically from 1937 to 1940, when the Association of Public-Safety Communications Officials-International (APCO) introduced the original “Ten-Signals” system to streamline radio communication between law enforcement officers and dispatchers. These early codes laid the foundation for what would become one of the most efficient and widely adopted communication systems in modern emergency response.
Over the years, police codes evolved in both form and function. In 1974, APCO further expanded the use of these signals to keep pace with increasing demands for speed, clarity, and coordination across jurisdictions. Interestingly, the idea of police shorthand began even earlier—Morse code brevity symbols first appeared in the June 1935 issue of The APCO Bulletin, adapted from the procedural shorthand of the U.S. Navy. While these were originally intended for Morse code transmissions, their influence would help shape the voice-based police codes we use today.
