What Is a 31.11 Police Code? 31.11 Police Code

The 31.11 police code meaning for the police forces is Tampering with Identification Numbers.

The 31.11 Police Code is a designated code used by law enforcement to indicate the criminal offense of Tampering with Identification Numbers. This offense typically involves altering, removing, or obscuring serial numbers or other identifying marks on property—most notably vehicles, electronics, or machinery. The goal of such tampering is often to conceal the origin of stolen goods, prevent law enforcement from tracing the rightful ownership, or facilitate fraudulent resale. When officers refer to the 31.11 Police Code, they are calling attention to this specific illegal action, which can be crucial in theft investigations and property crime cases.

Using the 31.11 code in police communications enables officers to report this offense quickly and clearly without having to describe the violation in full detail. By relying on standardized numeric codes, dispatch centers and officers can transmit complex legal information in a format that is both concise and widely understood throughout the law enforcement community.

Why Police Use 31.11 Police Code: Efficient Communication in the Field

The development and use of police codes like 31.11 stem from a long-standing need to make law enforcement communication faster and more precise. First introduced as part of the APCO Ten-Signal system between 1937 and 1940, these codes were designed to reduce miscommunication and speed up radio exchanges. Over time, the system expanded to include codes like 31.11, which focus on specific legal violations.

In real-world scenarios, the 31.11 police code is especially useful during vehicle inspections, property seizures, or when suspicious items are found without proper identifying numbers. Rather than wasting precious time describing a situation involving “tampering with identification numbers,” an officer can simply state “31.11,” and the meaning is immediately understood by dispatch and fellow officers. This allows for smoother coordination during investigations and helps prioritize urgent calls effectively.

What Is Tampering with Identification Numbers? Details Behind 31.11 Police Code

Tampering with Identification Numbers, as defined under the 31.11 Police Code, refers to the intentional act of changing, erasing, damaging, or removing identifying marks placed on property for security or tracking purposes. These marks often include serial numbers, model numbers, and most notably, Vehicle Identification Numbers (VINs). Tampering is frequently associated with attempts to hide the origin of stolen property, forge ownership records, or sell stolen goods through illegitimate channels.

In the context of vehicle-related crimes, tampering with a VIN to hide the vehicle’s true identity is a common tactic used by car thieves and traffickers. When police encounter such cases, they categorize the offense under code 31.11 and proceed with investigations based on potential theft or fraud. This police code not only alerts others to the seriousness of the offense but also ensures that the proper legal charges can be initiated.

The Importance of 31.11 Police Code in Modern Policing

Today, the 31.11 Police Code remains a vital tool for law enforcement agencies across the United States. Its relevance lies in its ability to instantly convey the nature of an offense and streamline the communication process between officers, dispatchers, and support units. In cases where rapid response is needed, or detailed evidence needs to be logged and categorized, the use of the 31.11 police code minimizes confusion and maximizes operational efficiency.

Because tampering with identification numbers is often linked to organized crime, stolen property rings, and fraud, the 31.11 code is frequently used in multi-agency investigations. Police scanners, legal documents, and arrest reports commonly reference this code when officers encounter defaced or altered equipment or vehicles. As a result, it plays a crucial role in enforcing property laws, preserving evidence integrity, and protecting public safety.

The Legacy and Evolution of Police Codes: From APCO to Today

Police codes, including 31.11, originate from a long-standing effort to streamline and standardize law enforcement communications. The system was initially conceptualized by the Association of Public-Safety Communications Officials-International (APCO) during the years 1937 to 1940. These codes were built to simplify radio transmissions, minimize ambiguity, and ensure clear understanding during high-stress, time-sensitive situations. In 1974, APCO expanded and formalized the original set of codes to better serve the evolving needs of modern public safety professionals.

The 31.11 Police Code, like many others, represents a targeted way to convey complex information quickly. In this case, it alerts dispatch and other officers that a suspect is being investigated or charged for Tampering with Identification Numbers, such as Vehicle Identification Numbers (VINs). This type of offense is closely monitored because it often signals broader criminal activity, including auto theft and trafficking in stolen vehicles.

Interestingly, the earliest versions of these communication protocols go even further back. In 1935, APCO’s bulletin proposed adapting U.S. Navy Morse code brevity systems for use in police radio—though those early ideas were designed for Morse, not spoken dialogue. Over time, these codes evolved into what we now recognize as modern police ten-codes and number-based signal codes.
